14b typical max 270whp
s16g typical max 340whp
evo 16g typical max 400whp
14b typical max 270whp
s16g typical max 340whp
evo 16g typical max 400whp
When he ran the 11.6 @ 116 he told me over the phone the car was under 2800lb total weigh with driver. I specifily remember this becuase my car was about #280lb heavier and leon and I discussed at lenght the differances between the cars and each area of weight differance. We both agree that the 14b was not going to make more than 315-320whp and all the improvements we could make were in the chassis/weight/driveline departments.
As for curts car. The only way I can see it is it's a combination of a lot of factors.
he smashes the shifts...that's worth atleast 1.5mph right there over normal shifting.
he has atleast 100lb standard weight removed from the car...
some of that weight is rotating weight that helps even more than these hp/weight/mph calculators take into consideration.
The tuning/fuel/parts combination is running the stock turbo ragged and this is probobly only possible in the cold fall temps. I would guess he's making in the 425whp dynojet range.
BUT untill you hear it from the horses mouth..using curts' car for an example is kinda moot becuase no-one knows the exact details for sure.
other than this car there are no examples of an evo8 16g running 450whp.

Here you go!

Not just "A stock EVO" for comparison, but MY stock EVO for comparison. Base line run on that sheet was from about a year ago after a full break in (2000 miles) on the car.
And here is the same car, same day on pump gas:

And befor anyone brings it up, the graphs say "fly wheel HP" This is because on a dynapack dyno you can input a "fudge factor" to give you fly wheel HP instead of wheel HP. The fudge factor (tcf) at Godspeed is set at 1.00 and gives you a direct reading of the wheel HP. The baseline run of 232 wheel HP shows that the dynapack reads almost identical to an AWD dynojet.

I would just like to point out that trap speed is also not the best power indicator. Here are a couple of examples that I have seen first hand:
- removing my wing (GT style) at around 130mph yields ~2 mph
- Going from 26” tires to 23.5” tires yields ~4-5mph
So if you are trapping around 130mph and you change your tires and remove the wing, you could pick up as much as 7mph with out changing your car’s power output. According to the “trusty” hp calculator, that is worth ~80hp on a ~3000lbs vehicle!
