Dynojet is the official NASCAR dyno. The tuners use dynojet because of its standard feature. Renntech runs baseline with it and final results with it. I
Then goes through conversion(actually powertrain loss %calculation) and gives out flywheel hp. So as most tuners. I believe that, at least, you need to stick with one dyno product to get the consistency.

I should do at least high 12's. As everyone pointed out, yes I sucked at 60' almost 0.7 seconds slower than my best 60'(which was 1.817) but somehow the car made a comeback, which means that there was enough HP available to reach 110 at the end. I used to get 4.83 for 0-60mph. And that's before pulley. These days, I get about 4.5. that means something.

HP was not calculated by seconds.
HP is calculated though the equation that uses how much power required for an mass to travel 110mph at 400m.

Forced induction engine performs a lot better than NA in a cold weather. And most of those claims are not supported by actual dragsliips. So I don't buy their claims no matter what. 12.5 I will buy because it's from the magazine.

Also What matters in real life is Wheel HP and TQ , not the engine HP and TQ

I must say for a 2.5 60ft, your ET is VERY good. You must have LOTS of HP. I do 13.0 but only trap 108 (with a stock E46 M3). But that's with a 1.9-2.0 60ft. If I had a 2.5 60ft I'd be in the high 13's for sure. Gotta' have lots of HP to make up time in the 2nd half of the 1/4 mile. Well done. If you could get the 60t down, you would do 12's easily.

With Gtech's measure, I was producing 338.2bhp and 383.7wtq.
Given that i used smokemup.com's calculation of 434bhp, if this numbers are close to the real or actual hp produced at the time including transmission loss and drag coefficient. I am producing 433bhp(just with 22% tranmission loss).
I am more impressed and impressed with this car. Can't wait until I put my headers on this weekend.

my friend, the m3 owner was also saying that he felt like he was in W211 E55 when accelerating with mine. it's just an opinion but it counts. So please W209 CLK55 owners.. wait 1000 miles patiently to breaks in and maintain well.

this is why your HP calcs are working out

at 35deg a 350hp car can actually be "making" 400hp, just b/c of weather conditions.
