Re: Spring Dyno Day Results and Pics!
 

Sweet. At DB? That's a nice place. I also like that it's in Rogers so I don't have to drive way into the cities and get lost going the wrong way on some one way street or something (I'm actually not bad at directions, I just don't like driving in the cities - don't like driving in St Cloud much either).

I should be getting it back to AWD sometime in the next week or so. Then I can actually accelerate again instead of just burning the tires in the first 3 gears, well 2 since I almost never put it in 1st gear.

Scheides..I WAS there with my car..you just didn't care to go see it I guess.

Re: Spring Dyno Day Results and Pics!
 

i bet drive train loss is somewhere around 15-18%. At least that would be the case with the EVO, and im sure the early dsm's are different but you can expect about that much.

Re: Spring Dyno Day Results and Pics!
 

According to what the stockish EVO's dynoed at, loss must be over 20% or closer to 25%. That doesn't sound unreasonable does it? Maybe on a dynojet you could figure 15%?

Was the dyno in 'shootout mode'? I heard that might make it read a little higher hp numbers than it otherwise would because of corrections being different. I was reading about the dyno dynamics dyno after the dyno day to learn more about them, and that's what I got out of it -- besides about 3 different forums calling them the heartbreak dyno because of lower readings than any others.

Re: Spring Dyno Day Results and Pics!
 

Matts right, I've been told drive train loss on my dsm was about 18% or so on a dyno dynamics.

But yes, dyno dynamics are the lowest reading dynos out there, yet most accurate imo. Either way, a number is just a number and doesn't really mean a whole lot. Now a track number...that's different :)

Re: Spring Dyno Day Results and Pics!
 

My stock evo dyno'd at 233/248 stock is like 278 or somewhere around their so you figure about 18% or so. 25% is high.

Re: Spring Dyno Day Results and Pics!
 

Now how much drivetrain loss does a fwd dsm get?

Re: Spring Dyno Day Results and Pics!
 

No shit, Dyno don't mean nothin' if you can't drive worth a damn.

Let's see some timeslips from all the dick waggers! ;)

Re: Spring Dyno Day Results and Pics!
 

i went 14.2@99.99mph with a 2.6 60ft, hehe. I can't wait to see what it'll do now. I'm going to go out on a limb and say I can get 12's with it next time it's out. w00t.

Re: Spring Dyno Day Results and Pics!
 

14's at a high mph. :spin:

Re: Spring Dyno Day Results and Pics!
 

Well I was thinking yours was the one that was claimed to have a couple pounds more boost than stock? Am I maybe thinking of the 227hp one below then?

Here's the two I was going off mostly:
evo 8: 271 rated - 212awhp = 21.77% loss
evo 9: 286 rated - 227awhp = 20.63% loss

also the t25 gsx only pulled off a 149, although it's old enough that it may need some work to be as good as stock.

Re: Spring Dyno Day Results and Pics!
 

I ran on the dyno day because 50 bucks didn't sound too bad to me, and because it sounded like fun -- I've never even watched a chassis dyno in person before, only an engine dyno a few different times with my V8 Ford racecar engines.

It seems that there are quite a few people who think a car CANNOT be tuned without a dyno. Sure you will gain power, but I think you should be able to be tuned pretty solid before you get there if you've spent time driving and street tuning. If you are going to try some different parts on your car while at the dyno, then it would be extremely useful -- I would assume that the average person doesn't do a whole lot of that though.

For me, about 3/4 of the fun of having a performance type car is tuning it myself. I wouldn't have much fun to put on a bunch of parts and then hand the car to someone else to do the tuning, or especially have someone else do all the work on the car as well.

Re: Spring Dyno Day Results and Pics!
 

Yea with Scheides uping your boost a hair with Tephra and an Intake system that is what you made. ;)

So it could be more than 18%. :)

Re: Spring Dyno Day Results and Pics!
 

Evos are underated from the factory, if anything. They put down more power to the wheels AWD than STi's on our dyno and the STi is rated at 300hp. AWD Dynojets read very high.

To get from the normal numbers that our dyno gives AWD to AWD Dynojet numbers, you needs to take your numbers and add 18-20%. On EvoM they pretty much use 1.2 as the correction factor needed to go from an AWD Dyno Dynamics to an AWD Dynojet. So an EVO putting down 300awhp on our dyno might be around 360awhp on a Dynojet. The Dynopack(the one you take the wheels off and connect to the hubs) reads even higher than a Dynojet. The difference between 2WD numbers on the Dyno Dynamics and Dynojet is not as much.

For stock 2003-2004 Evo 8s, I usually see 205-210awhp. For the 2005 Evo 8s, usually 210-215awhp. And 220-225awhp for a stock Evo 9. Stock 04-05 STis I have probably seen 195-210awhp. Stock or close to stock DSMs are usually in the 140-150awhp range. Stock 02-03 WRXs are 145-155awhp.
