The Dyno Correction Factor formulas would increase the 182 HP to, say, 192 HP if you use the SAE correction factor, or 200 HP using the Race Dyno correction. 2 days ago · where we dropped the overall factor A 1. A worn disc and/or seat can cause dyno control problems. As it is on any Dyno Dynamics dyno it is possible either by accident or on purpose to get an over inflated rwkw purely because the correction favours hotter intake temperatures. 0 TFSI engines who want a medium level tuning package at a superb value price. dynapack's read 10-20% high and mustang dynos read like 10% low so between the two factors, 260whp on a mustang vs 320whp won a dynapack ain't that different. So before you knock the low numbers, remember this is not a dynojet that reads ridiculously high. There are 100+ professionals named Stuart Lane, who use LinkedIn to exchange information, ideas, and opportunities. We quickly identified and remedied a few problems, such as wideband signal being wired to the wrong input with O2 correction enabled. Tune is VERY conservative at 10. 2) SAE J1349 Rev JUN 90 correction shall be used, along with smoothing factor 4 or 5. Inlet air temperature Ambient temperature Barometric pressure Relative humidity Mechanical efficiency (Dyno Dynamics ATMC2 only) Resultant correction factor. 5 "Tuning" and Rolling Road Dyno (Pics/Vid) Post by PawnSacrifice » Tue Jul 13, 2010 3:48 pm Siftah wrote: Sounds like you've gone into this with the right sort of mind set to get some interesting stuff out of it, but not be dissapointed by a lack of gains or by not being given huge numbers. All of the stock JKs we have tested are not putting down anywhere close to the same numbers that the stock ones you guys are testing. Mark Boxsell. F20 / F21 Model Year: 2012 + Previous Generations. BW autorepairs Over 30 year repairing BMWs. It will be good to see what mph this car throws down at the track. Most Mustang Dyno's that aren't tampered with read very similar to my DD as well. The dyno test was done using a Pirelli Scorpion knobby. Re: Microtech Dyno Results actually its very very hard to compare dyno sheets its ok to compare dyno sheets of same car same dyno , before and after mod but it really varies from one dyno machine to another dyno machine especially the dyno brands , SAE correction values , etc Dyno Dynamics , Dastek Dyno , Dynojet. Lloyds ek"3" b-series build update pg2 (230bhp) dyno dynamics its a real dyno etc, but as far as im aware there is no true reading of hp on rollers as there are. LIABILITY RELEASE, WAIVER, AND AGREEMENT FOR DIAGNOSTIC TESTING EQUIPMENT USE The undersigned would like to utilize the diagnostic testing equipment of SPEED FACTOR RACING for my automobile. Do not confuse our rolling road dyno cell with lesser ones out there, it is a brand new, state of the art Dynotech 4wd by Dyno Dynamics and can measure up to 2400bhp at the wheels and load any car up for mapping safely at up to 600bhp per axle. There is always more torque at the wheels than at the crank. GFB have Australia's best performance turbo management solutions. Before and after means just that - the car does a couple of dyno pulls, the remapped file is flashed onto the car and the car does another couple of dyno pulls to illustrate the improvements. 15=DynoJet number" could be overly generous. A certified Dyno report consists of three separate, reproducible Dyno tests with SAE correction. I believe MRC have simply stopped spiking the peak boost to give a higher peak torque figure and instead improved their base maps to give a smoother power delivery. Again this is someone else's experience. These factors are NOT the same for atmo and turbo engines. He said it should be at 5. There are three graphs. Compute estimated increase in engine horsepower when an after market, racing upgrade or performance part has been installed with ET. How much should you expect to lose? Well, if it is running spec parts and has been properly maintained, almost nothing. Correction: "this is literally how every performancy BWM has been crowd-marketed". This means I dyno'd 4. In America, SAE correction is accepted as the standard. Then you can throw "Correction" in on top of everything, making different dynos, even more different. The horsepower number that the dyno read was just off from what Toyota claims, but the torque figure is considerably higher. But dyno's can't measure wheel torque, they can only measure driving force at the rollers and the speed the rollers turn. You can't compare Dynojet with Mustang, or Dyno Dynamics, and called the numbers low or high based on numbers alone, make sure at least the dyno's are the same first, then ask for SAE to be applied if the dyno allow for that correction, compare dynojet to dynojet when the correction and smoothness are the same for more accurate comparisons. The correction factor is used to give a realistic idea of what someone would pull on a dyno at sea level. Correction factors generally provide a pie in the sky estimate that means very little to most engine builders. So for the dyno day the first three graphs are with a 13% correction factor to be close to a Dyno Jet and the last is with no correction factor. It is used to insure that the HP of the car is comparable from one day (or even hour) to the next. On a hotter day in the summer the car would make roughly 170 sae hp at the wheels. Unfortunately, this has lead to a war of correction factors (CF). 98 correction factor, that mean the dyno software will take off 2% from your horsepower reading. net but haven't created an account yet. 1 that the ‘uncorrected’ power of the day is corrected by. The SAE factor is the industry standard and is more of a middle-road reading in terms of correction. There's plenty left once the. 3- To make numbers look BIG, dyno operators dial in correction factors. A very nice build. The last half of the track is KEY to a good speed. Emerson has a large staff of highly trained personnel strategically located throughout the world, who are available for your. The DD Precision 2WD is a very versatile machine, capable of running any 2wd vehicle including Motorcycles, Quad Bikes and Go Karts. Shootout mode was designed by dyno dynamics around 3 years ago. The stock Audi power figure for the C7. Previous "Mods": ADD W1 Dual Inlet Catch Can Dyno: Dyno Dynamics (No correction factor was applied) If you want to correct for your local Dynojet, add about 10-12% to these numbers. 6rwkw with heaps more torque across the board. 92" , maybe thats why sometimes people say the yanks dyno numbers can differ to ours it could be the difference between std dyno correction and SAE but im only speculating here, when running simulator programs i use SAE and 600RPM/sec acceleration rate. Then, of course, you get into environmental factors. Dynojets are historically the only dyno that has been consistent from dyno to dyno. Uncorrected/actual power this car is probably around 1,000hp. This is achieved by gaining drivers wish insight, on road test driving, mechanical experience and dyno readings. And that includes pools, but not kiddie pools, endless pools or standalone pools. Unfortunately, this has lead to a war of correction factors (CF). Obviously we would be comparing apples to oranges with every dyno on this forum if correction wasn't used. LIABILITY RELEASE, WAIVER, AND AGREEMENT FOR DIAGNOSTIC TESTING EQUIPMENT USE The undersigned would like to utilize the diagnostic testing equipment of SPEED FACTOR RACING for my automobile. Just the correction factor on our baseline run of the MZ3 makes a 4. 6% low (due to the high temperature). laboratory equipment shall be set to minimize correction factors by controlling inlet air as close as possible to "reference atmospheric conditions". This link seems to imply that Dynojet's HP numbers have a built in correction factor to est. Vehicle Information. up here the average SRT makes 290 to 325 depending on the dyno and the correction factor. Page 2- DynoJet Vs. Trade-ins etc. Vehicle identification. Dyno oxygen sensor is not connected. Correction factor used, Dyno Used, etc. The correction factor was. The units arrive with a fully terminated loom to suit the engine it has been configured for (VAUXHALL in this case – please see the images to confirm they match your engine), as well as loaded with an optimised base-map that has been developed in house on our L&S engine dynamometer and rolling road tuned our Dyno-Dynamics rolling road. A lot of letters and numbers that didn’t mean anything yet. The dyno is a Mustang Dyno and I was running no correction factor. This is a correction factor of 1. These CF's are mentioned. Theres many types of dynos out there. the post above is a a dyno dynamics dyno which is awsome, we have one and it was run in shootout mode which means if he were to bring the car to us and run it on shoot out mode he would read the same numbers, a dynojet will tend to read about 13-15% higher than the dd dyno,. Maybe the problem is that a Dyno can be influenced by so many uncontrollable factors on the day, eg weather/humidity that if you go back again tommorrow on the same dyno, you may get 20HP more. but a standard can never be made since correction factors, loading and environmental factors (elevation, humidity. It's my mistake because normally Dyno Dynamics will show very low hp compared to DynoJet so they have this mode to correct the hp to be close to DynoJet. I think it's a valid 10hp gain as they were done back to back. So each dyno can be calibrated with a correction factor to compensate for 'drive train loss' and calculate BHP. Dynojet dynamometer runs, drivetrain losses, and how dyno plots can vary wildly. Custom Tune-able with the free EZ-Tune Software – Custom mapping if you want it via Bluetooth or RS232 Serial Connection Bluetooth™ – Use the included USB Dongle or use the free dash App for Android. The SAE J1349 test procedure includes an engine horsepower correction factor so that, for example, dyno readings taken at 3500 feet on a 40 degree day can be compared with dyno readings taken at sea level on a 77 degree day. If I recall correctly, the RS Wouter did the runs on is a Dyno Dynamics and they did the run in. My car laid down a pathetic 237 RWHP number and had it been run on a DynoJet with STD correction factor it likely would have been around 270-275RWHP. BMW 435i F32 N55 MY2014. Dyno Results - posted in DC5 Technical - engines, exhausts and induction etc: Got a shout off a mate today who said the local autofactors were having an open day, with a rolling road thingy there. Henceforth, the relations (bz i >0 if h˙z i i>0 b z i <0 if h˙ i i<0 2 The two factors are not exactly equal, as the spin iis ipped as part of a vertex and not independently. Can run very low power up to 1200 Horsepower at the wheels Test Cars, Trucks, RV, Go Karts, Quad Bikes and Motorcycles Measure HP, Torque Time, Tractive effort rpm etc. Analysis was performed for the intrinsic influencing factors of the development of the existing building energy-saving renovation market and the interaction law of feedback relationship. We often use correction factors to compare what the cars would put down at sea level. Dyno Dynamics are Load Bearing Dynos that apply pressure and measure force against that load as torque which then is used to derive power. Correction factors allow a car to make the same power on a dyno no matter what the atmospheric conditions are. mustang dynos are usually higher than dynojets, load dynos usually dyno the lowest, but results are like hydraulic dynos which are extremely accurate in detecting change, but tend to be 16% lower than dynojet and dynapacks. 22%, so I really made 366whp. It's something I should have asked when I had my car last RR'd on a dyno dynamics road. 0 Original Spec: 1990 Mk1, PS, EW, Spoiler, Mariner Blue, Sill Plates, Finish Line Gear knob, TWR Hardtop.

SCANIA trucks have these fitted as well as some tourist coaches. The same DYNO-MAX Inertia Calculator also makes it easy to determine the equivalent inertia required should you choose to gear the flywheel up or down from the shaft where the Vehicle Speed Factor was referenced. Ignore Engine Rebuild Options; Only Include Engine Rebuild Options; Active Autowerke Low Compression Motor; Alekshop 4. Like up to 10%. Colorado Springs, CO. Which results in exceptionally high transmission losses to other dyno's. 4 rwtq, I don't have dyno numbers before tune and IC upgrades, but I have heard stock 2018/2019 numbers are 256 rwhp and 347 rwtq ( for a manual) This is on 93 octane. This is the exact same software as used at Summernats and is the new industry standard for Dyno Dynamics. All those factors do effect the results, however the dyno software is normally used to correct the numbers to standard conditions. 12 horses less than in STD correction on the same dynojet and 44 horsepower more than on the Mustang dyno. 2 Dyno Testing Procedures. The JKM K03 Stage 1. Then, of course, you get into environmental factors. It really doesn’t matter which dyno you use as long as all the runs are done at the same one as your baseline. The dyno will have a method to set the desired RPM. Trade-ins etc. 92" , maybe thats why sometimes people say the yanks dyno numbers can differ to ours it could be the difference between std dyno correction and SAE but im only speculating here, when running simulator programs i use SAE and 600RPM/sec acceleration rate. 5 is 450BHP, so Im not sure if my 433. There is no way of applying a load, it simpily measures the force (horse power) needed to spin up two steel drums. NIR atmospheric correction algorithms on Rrs products from MODIS-Aqua. Well, that's also built in. Dyno Dynamics [DD] rolling roads are known as the "heart-breaker" as the DD figures tend to be lower than owner's and or tuner's claims. http://arxiv. It wasn’t that long ago that the stock intake manifold was one of the first things a builder would swap out to free up a substantial chunk of power, even for mild street builds. To compute the HP a correction factor is used. Dynojet dynos feature large and very heavy rollers while others such as Mustang and Dyno Dynamics are load based dynos that have small rollers. I ran dyno pulls on my 06 Speed 6 on an AWD Dyno Dynamics dyno yesterday. In the newer digital dyno software, the ctrl-X shortcut is no longer available. Getting locally tuned tomorrow, tips for A/T please. A smoothing factor up to five (5) is permitted. I did 343 on a Dyno Dynamics in Scottsdale, AZ. Just the correction factor on our baseline run of the MZ3 makes a 4. The scaling factor function of the componentcharacteristic maps were optimized based on Genetic. There are many ways to control this load in the software, or you can use pre-programmed factory routines to do more generic testing, like power sweeps. Dyno Dynamics rolling road. Don’t Trust Strangers! How Dynos Lie and When to Believe One by Khiem Dinh Khiem Dinh is an engineer for Honeywell Turbo Technologies at the time of this writing. Correction Factors Correction factors are used by both dynos to account for varying atmospheric conditions such as temperature, pressure, and humidity. Also a bog stock LS1 Caprice with harrop supercharger got 307rwkw (see: Welcome To Westernlink Automotive & Dyno Tuning). I bet it will make more power with a smoother tire. ONTARIO TIME ATTACK DYNO PLOT SUBMISSION Correction Factors Dyno type \ Drivetrain FWD RWD AWD DynaPack (hub dyno) 0. Froude Hofmann. Dynamics reads 15 % less than a Dyno jet and some dyno dynamics owners dial in 15 % CF to make their customers happy:) Maybe there was 0 CF on this GTR's run. These factors are NOT the same for atmo and turbo engines. This dyno dynamics was tested vs a dynojet the same day before by a bmw 135i guy, and reads about 10% lower. AFR: Will seem a little leaner due to using the Dyno's tailpipe sniffer and my exhaust being stock. Dyno Dynamics [DD] rolling roads are known as the "heart-breaker" as the DD figures tend to be lower than owner's and or tuner's claims. Type of Dyno: Dyno Dynamics Baseline # for a stocker at the dyno: Unknown (Stage 2 w/ el headers put down 249whp and 225wtq) Boost:19 lbs Fuel:E85 Target AFR:Unknown SAE Corrections:Unknown but this dyno is reading ~15% lower than Mustang dynos in the area Peak HP at RPM: 318. The same DYNO-MAX Inertia Calculator also makes it easy to determine the equivalent inertia required should you choose to gear the flywheel up or down from the shaft where the Vehicle Speed Factor was referenced. I'm working on a set of F2 CBR wheels for commuting duty and will dyno it again with them on. I bet it will make more power with a smoother tire. It's nothing to do with the correction factor (that's based of the temperature and humidity readings). 6L Stroker Motor; Dinan 4. 4) Testing Range (check one): ( ) Dyno graph shows decreasing power for 300 rpm from the peak horsepower level. The new factor is about 4%. In all fairness, dyno's in different parts of the country use different correction factors. Analysis was performed for the intrinsic influencing factors of the development of the existing building energy-saving renovation market and the interaction law of feedback relationship. This correction factor is meant to predict output in varying atmospheric conditions and is a +/- 7%. I hope this attachment works and adds another bit of data. We are in the process of aquiring the Dyno Dynamics Load based dyno. I wouldn't try to use a set % when compairing the differences in dyno's. Fluid Flow. Crankshaft horsepower vs. Dyno's are a tuning tool. Note that the The Dyno Dynamics dyno is an eddy-current dyno, it is not an inertia dyno. Which typically reads 4% higher than the more widely used SAE correction. 40 is what they use to get dynojet numbers. I understand that due to the nature of testing to be performed on my automobile by the. EFI University is the first school of it's kind, offering Aftermarket Electronic Fuel Injection training classes and seminars for the high performance racing industry at affordable prices. Factor corrects horsepower for normally aspirated internal combustion engine to a standard humidity, pressure and temperature after dynamometer measurement. You can basically follow the trend. Mustang dyno however tends to be all over the map and have bigger variance because there is much more to deal with like did you use the same weight at each dyno, the same correction factor, were the weights calibrated, brakes, etc that control loaded. It's easy to see why a dyno operator would use the STP J-607 correction factor for engine dyno runs - it records a higher horsepower number. J607 specification formula does not perform humidity correction. They do read somewhat low when compared directly to an inertia Dynojet so some shops will have a special correction factor they apply to show you "Dynojet-like" numbers. This is a discussion on Getting locally tuned tomorrow, tips for A/T please within the Veloster Turbo ECU Tuning and Data Logging forums, part of the Veloster Turbo Garage category; A/t. I didn't test it before putting the RocE and exhaust mods on, so don't have a before and after figure. In 1985, a flow bench was purchased and hundreds of hours a month were spent on developing cylinder heads, intake manifolds and camshaft combinations. As for dynos, it's not like opinions and a-holes. We often use correction factors to compare what the cars would put down at sea level. We got it? Ok. But dyno's can't measure wheel torque, they can only measure driving force at the rollers and the speed the rollers turn. Seems pretty conservative to me. Correction Factors Correction factors are used by both dynos to account for varying atmospheric conditions such as temperature, pressure, and humidity. 04 depending on how hot, etc. Dyno Correction Factor Calculator. The Dyno Dynamics is known throughout the industry as being the "heartbreaker" dyno - because it breaks the heart of everyone that thinks he or she has 500 hp at the wheels when he or she really has 435 hp. Here is the sheet from 2013 on a Dyno Dynamics fwd:. Dyno pull with Shoot 6F (6 Cylinder Forced Induction). Proper use of dyno correction factors (a must for those professional tuners) I would like to start a discussion that is of great interest to those here on PPB: The dyno. Trade-ins etc. If the wrong rate is used the car will be out of tune. There's plenty left once the. ), the Dynojet dyno is an inertial dyno. Opinion can be based on nothing, or great education on that subject. Right now we are assuming 15% for all RWD results and 20% for all AWD vehicles, obviously that isn't perfect since there is a large variance between a Dynojet and a Dynodynamics. A great resource listing a slew of Dyno Dynamics HP baselines is available in the Gallery section at the KTR Performance Dyno Gallery Web Site. 85 – 400 = 70. This link seems to imply that Dynojet's HP numbers have a built in correction factor to est. If you were testing on a really hot day, with high humidity, there would be some impact. The Dyno Dynamics does not use the coastdown method to estimate a flywheel figure, its results are displayed above for all to see the Correction factor used in shootout is called ATMC2 if you want to know more about the dyno and how it works - drop me a line [email protected]. Do not confuse our rolling road dyno cell with lesser ones out there, it is a brand new, state of the art Dynotech 4wd by Dyno Dynamics and can measure up to 2400bhp at the wheels and load any car up for mapping safely at up to 600bhp per axle. Right now we are assuming 15% for all RWD results and 20% for all AWD vehicles, obviously that isn't perfect since there is a large variance between a Dynojet and a Dynodynamics. Dyno Dynamics, the manufacturer of Australia’s leading dynamometer brand, has for many years been considered the benchmark for both accuracy and repeatability. For a basic rundown on the difference, here are a couple of links to articles about dyno's and how they work Chassis Dyno Guide - Frequently Asked Questions About Dyno Tests - Hot Rod Magazine.

The rear wheels were chocked, the large dyno cooling fan located at the front of the car, the intake air temp correction probe stuck near to the engine air pick-up, and testing could begin. On this Valentine's Day, you can also add a box of chocolates with flower bouquet. 6) SAE J1349 Rev JUN 90 correction shall be used, along with a smoothing factor of 5. I can say my car running multiple runs on the same dyno over the past year has netted a result within 3rwhp of it's. M SAE The whole point of a dyno correction factor is to be able to test in different atmospheric conditions (eg. Most other dynos require you to purchase additional equipment to use the machine - this must be taken into consideration. There is no adjustments on the weather stations but placing them in the hotter spot in the room will cause the correction factor to be higher which inflate numbers. Steady state test at a selected RPM or a vacuum gauge reading switch on/off the ac and note RPM and Hp drop? Don't have to do a WOT power pull for a few fancy graph comparison. Some of these units are very strong to 2400 ft/lbs. Because atmospheric conditions (ambient air temperature and pressure) affect air density they therefore affect power output. In the newer digital dyno software, the ctrl-X shortcut is no longer available. A certified Dyno report consists of three separate, reproducible Dyno tests with SAE correction, with the car owner’s name, car number, car year/make/model, shop name and phone number, and Dyno operator’s name on the Dyno sheet, accompanied by a completed ST Dyno Certification Form. Customer name. Correction factors generally provide a pie in the sky estimate that means very little to most engine builders. They dyno all the cars above 1 mile of the sea level, also they used low octane quality fuel, and that also adds to the factor why hp was so low, and why computer had to re-calibrate things. Well, after hearing all the hype here on Prime about the 1997+ OEM Header/Exhaust combo, I decided to try it after I found out that Vance was selling his 2003 OEM Header/Exhaust/Cat combo in the classifieds.

If you look at the print out using the "conditions" view, you will see how much correction factor is being applied to your dyno run. Power Run Test on Dyno Dynamics Chassis Dynamometer. Hi BMGJet , I did this 25 years ago on my dyno dynamics chassis dyno. Without getting into that debate about what is a “real dyno”, just understand that when you see stock numbers of 145 to 150 then it is likely it was from an inertia dyno (Magnaflow NC exhaust advertised results for example). The correction factor the dyno's use illustrate this fact. - 10 rwkw off that and theres a round about 357 rwkw from a roller dyno. I assume your settings were the same back to back, but it's still nice to have that as a note. Here are the dyno graphs for before and after the headers & pulley. Their cammed cars got around 280-285rwkw. 860 Dyno Dynamics 0. There are alot. DynoDynamics are recognised as industry leaders in the manufacture and design of 2WD and 4WD systems. SIDE NOTE: I'm going to plug that log into VD again and mess around with the correction factor and see what it takes to make it read the same as the Dyno dynamics Attached Images Eth last night. I put down 247whp on the low reading Dyno Dynamics Dynamometer. Date, time. Does this cover dynos like the built-in one at VIR that has a dynojet correction factor? The "VIPER" dyno at VIR is big $ and used for high level testing, etc etc. Now when tuning a car you must use a correct ramp rate on it. Dyno Dynamics - Shoot out modes. back on the dyno dynamics id be up around 185kw, so my results on the 2 dynos vary wildly between what we would consider to be ordinary to very good (for an auto) So we all know dynos vary, but this enormous variation just drives home the pointlessness of comparing cars that have been run on different dynos. and has led the way in adapting the chassis dyno from a simple measuring device to being a highly sophisticated diagnostic instrument. There are also more parts to heat than purely gearbox oil. On a Dyno Dynamics Eddy Current chassis dyno with 2 smallish 12” diameter rollers, using SAE J1995/SAE GROSS correction factor. A certified Dyno report consists of three separate, reproducible Dyno tests with SAE correction. What settings was WinPep on for smoothing and correction factor? That graph was very choppy. SAE on my Dyno Dynamics averages 12% lower readings than a DJ using SAE corrections. If the temperature is colder, you will make more power and to normalize this the correction factor will start to be below 1. 12 horses less than in STD correction on the same dynojet and 44 horsepower more than on the Mustang dyno. guy #2: Dyno Dinamics 623WHP; Mustang dyno 591whp These numbers may give you a little idea. The most likely cause for the standard "flywheel" power discrepancy is the transmission loss being better, or worse than the industry standard. But for Motorcycle it is not need correction factor. Notes: + : J607 with Humidity Correction. Fuel trims were way off so fuelling was adjusted. If running a correction factor it is good to advise of it with the dyno sheet when making a post so people know the conditions. I would suggest that the workshop call us so we can diagnose if there are any problems Alan H Evans Managing Director Dyno Dynamics (A ust) Pty Ltd Ph: 61 3 9735 8900 (Office) 61 413 432 101 (Mobile) 1 5 Z4 OE tuning dyno results - Page 2 - BMW M3 Forum (E 90 E92) Page 1 of 16 3/27/2011. 15 correction factor. Dyno results. 7) Dyno graphs shall show horsepower and torque on the Y-axis (vertical), and engine RPM on the X-axis. Seems some guys are posting differences of 20%. Also keep in mind, the a 1/4 run doesn't have a lot of software/maths in it trying to turn a measured number into something that's comparable - the 1/4 uses a fixed method of making comparable numbers - TIME (no fudging/correction factors required to make time slips comparable). And if you're looking at actual peak number vs. 05 in HG, 81* and about 55% humidity. The amtec diesel conditioner was suggested incase i had a bad batch of diesel in the tank. This factor is commonly used by the performance industry, particularly on engine dynos. Getting locally tuned tomorrow, tips for A/T please. Dyno Dynamics is a load dyno with variable load control. This Correction Factor Calculator determines the dyno correction factor which is to be multiplied by the actual dyno data in order to correct for the effects of temperature, barometric pressure, humidity, and altitude. Uncorrected the horsepower was 163hp. Use Station Pressure reading and not the 'corrected' barometer reading. This means I dyno'd 4. I could go to 5 different dyno jets or mustang Dyno's the same day they would all read differently. Understanding 335i Dyno results and Correction Factors (300+hp@whlz stock!??) Login Register. There are alot. This is one correction factor which is open to huge abuse and also causes many innocent mistakes to be made from operators. 35 characters. if there is no setup done which some will not be bother, they will just use an estimate of 1. My dyno numbers are Max HP 287. We set the 2 step at 4000 just for now. necessary for power, torque, and correction factor calculations. Known dyno's can use a fixed multiplier to calculate crank power. Just as a heads up, Hondata prefers to use the older SAE correction factor. In both cases the loss is over 18% which is pretty much the case with Porsche PDK cars from our club on the same dynamometer. Dynojet dynos feature large and very heavy rollers while others such as Mustang and Dyno Dynamics are load based dynos that have small rollers. Control-X and pop in a new correction factor on the Dyno Dynamics dyno then your done, you have better numbers. Both of these applications are done inhouse and utilise the Dyno Dynamics to obtain the best outcome based on your vehicle. These figures also factor in a weather correction. The BMW was already on the dyno, but Chris went through the various steps needed to secure the car on the dyno. Doesnt mean 1 tcf is wheel and 1. Most Mustang Dyno's that aren't tampered with read very similar to my DD as well. It's not like dyno's are useless, but try to consider each one as it's own competition. The larger your dyno correction factor the more suspect the power numbers. Re: Mainline VERSUS Dyno Dynamics Its accurate alright, the last time I had mine on Carline's dyno was in 2007, due to time constraints it was a bit hot out (34 degrees and over, try walking around in that after being awake for 56 hours straight) and the dyno reported a temperature of 37 degrees, which is dead on considering the heat inside. Correction factors allow a car to make the same power on a dyno no matter what the atmospheric conditions are. Granted, this is on a Dyno Dynamics set up to read like a dynojet. By the analysis of the different factors influences it can be determined the necessary precision of measurements, so that the results of the test might be conclusive. and distance during cost-down. 53, in our first meeting. Dyno Dynamics Correction Factors:. The TC factor on a Dynapack dyno is a correction factor, with it being 1. 5978 FT, 1. 6rwkw with heaps more torque across the board. According to Dynojet, SAE is the proper factor for tests done in the US, and it's the one I use exclusively. All of my search term words; Any of my search term words. There are three graphs. If the temperature is colder, you will make more power and to normalize this the correction factor will start to be below 1. Vehicle identification. All dynamometers are not comparable and there are huge differences in their design, functionality, and capabilities. I am confused why some dyno operators insist on putting altitude on their charts and swear that it's a factor. 7) Dyno graphs shall show horsepower and torque on the Y-axis (vertical), and engine RPM on the X-axis. Tune is VERY conservative at 10. Rotronics/Overmarsh Engineering, France. When I mean time I literally mean on a minute to minute basis as room temps where dyno's are located can vastly change within a short space of time. A dyno chart is a two-dimensional representation of an engine’s horsepower and torque over the engine’s speed range, as measured by a device. 223 CF, SR-Tuning, PowerDyne Mustang Dyno 238 WHP 246 WTQ. VX100_Dyno Todd is the original, all motor 2GNTer and can be found running his non-turbo at the DSM Shootout each year against the turbo guys without worry. If you look at the print out using the "conditions" view, you will see how much correction factor is being applied to your dyno run. They do read somewhat low when compared directly to an inertia Dynojet so some shops will have a special correction factor they apply to show you "Dynojet-like" numbers. Yes all of those things can be a factor, you should be looking at 370 plus with those mods, standard intercooler is crap and at best you get 2 runs out of.
Dyno Dynamics Correction Factor.
