I'm not much of an expert but why are the whp #'s on a DynoJet so much higher than on DynoDynamics w/ the same exact mods ? There seems to be about a 40-50whp difference between the two Dyno's. I've seen people claiming 320whp w/ a TBE, MBC and a Flash. A stock Evo IX puts down 220whp right? I doubt that you can get 90-100whp from just a TBE, MBC and a Flash. With the same exact mods I've seen 270-280whp on DynoDynamics. Does this mean that 320whp on a DynoJet is roughly 270whp on DynoDynamics? I can see a 40-50whp gain w/ just a TBE, MBC and a Flash but not 90-100whp. Anyone else see this trend ?

 

I made 280tq/270hp on dynodynamics with TBE and 21.5 psi (stock bcs). Stock IX's baseline betw/ 210 ~ 220 on this particular dyno where I had my car on. Dynojets read higher than DD, in general.

 

I figured right around 220whp for a stock Evo IX. DynoJet reads ALOT higher especially w/ mods in the equation. Is it fair to say that 270whp on DynoDynamics is the same as 320whp on DynoJet? I'm really confused with people doing the same mods, same brand even, and getting such different/inflated results on DynoJet. I would be really dissapointed/pissed to find out that my car is putting 50whp less to the wheels than my tuner's Dyno showed. I could pretty much look at your engine setup and make a guess within 50whp. What's the point of getting on a Dyno that's not accurate, I could make an inaccurate guess myself.

 

Usually Dynojets read higher than the Dyno Dynamics...

My first dyno was on a Dynojet. WIth dp, hfc, catback, intake, mbc and e-flash at 22psi i saw 328whpand that waht a hot day. Exactly after six days i dyno'ed the car again (Evo-NY Dyno day) on a dyno dynamics and i saw 299whp... that's 29whp difference...

However, since then i have been tuning and dynoing the car on the same dyno dynamics so i can always have comparable data instead of getting confused with dyno comparisons, defferences and so on...

Since then my 299whp on that dyno have become 344whp on the same gas and boost pressure.

Now theoritically if i apply the 10% difference that i saw on these two dynos, if i dynoed the car again on the Dynojet i would probably see almost 380whp. Is it true? i don't know until i do it...

Try to use only one dyno get you are tuning and checking your progress and of course visit the track. E.T. and Trap Speed are 100% accurate if you want to see how powerful your car is and how you have progressed with your mods...

 

Were these figures obtained from “The Shop” dyno in CT?

 

All dyno's are diferent, its just the way that dyno is calibrated, some dyno jet vs dyno jet will be different, no dyno is the same, the best to do is look at your before and after results or to compare 2 differenent dynos then use the same exact car on each dyno to compare your results

 

Yes...

Their service is incredible and all the guys there are very friendly... and Jimmy the boss is Greek... and i am Greek....

Hopefully this Saturday when i installed the last parts i have on the car and retune i will break the 350whp mark on pump...

 

As stated before, the old school Dyno Dynamics dynos have a calibrationn that produces heartbreaking numbers. The DD dyno at the Shop uses the newer calibration settings and will probably read closer to the dynojets. It makes goal seekers happy.

 

This is simple stuff. It's not about one dyno being inaccurate and the other being accurate. It's all about before and after gains. Absolute numbers mean nothing, and it's this lack of knowledge that drives dyno owners crazy, because noobs think that one shop knows how to make so much more power than the other shop just because the dynos read differently.

DDs typically read much lower than Dynojets, and so do most Mustang Dynos (not all, though). You can't worry about absolute numbers. You just have to worry about what a stock Evo does vs your modded numbers.

 

My friend wait no more than the end of this month...

We will have dyno numbers on their dyno, on another dynojet and of course the track...

Also, last week i used some road dyno calculations which are based on car weight with driver, speed in mph, rpm, time in msec and and i run all of my last logs. The car averaged 377whp as i drive it on the road with 24psi spike in 4th gear....

As far as the Shop's dyno is concerned let me tell you that Evo IXs with the usual intake, TBE w/ testpipe, fp, mbc, custom tune read around 317-318whp at 22psi which is much less than the 345-350whp that this level of mods is seeing with the above package on the dynojets... And this is not last year but 2 weeks ago...

Similary Evo IX with similar mods as above saw 342whp.... BUT he was running 26psi on a 93/104 octane mix...

i would say that their dyno read around 10% lower than the dynojets, and until now it is proven multiple times.... Indeed maybe other DDs read even lower, maybe 12-15%, but don't get mistaken... even 10% on a 340whp car is 34whp less!!!

 

+1

As my friend Warr puts it...

Dyno racing cannot become a sport... Simply check the numbers of a stock Evo on that dyno... then check the numbers of your car... That's how is works...

Now "calibrations", non-calibrations, dynojets, mustangs, dyno dynamics, dynapacks, even Mahas and Vamags are just tools for car tuning...

 

Kouzman, you spend way too much time trying to defend this. I believe the DD at The Shop does read normally, but it's the fact that they normally apply a 1.1 CF that threw everyone off, because no one mentioned the CF that was being applied at first, so the numbers were much higher than normal for a DD.

 

A dyno is a tuning aide - nothing more nothiong less

What is relevant is

That the load is repeatable and that the machine has good resolution to quantify gains and losses

A dyno jet is around 60 - 70 K

Dyno Dynamics is just about double that

To me the power figures the machine spits out are meaningless - (although I understand that many customers are interested in them)

The main use of a dyno is to properly tune a car in a controlled envirnment

 

on pump gas i made 372/380 stock turbo on a dyno jet. and 22/23 psi 93 oct

 

DynoJet reads ALOT higher bottom line in every whp claim I've seen on this site. Is it fair to say that 270whp on a DynoDynamics is the same as 320whp on DynoJet? I'm really confused with people doing the same mods, same brand even, and getting much higher whp #'s on DynoJet. Again I could pretty much look at your engine setup and make a guess within 50whp. What's the point of getting on a Dyno that's not accurate and gives you inflated #'s? When you say DynoJet reads lower do you mean it's more accurate, I just want to know which Dyno gives you REAL #'s.
