i would guess your crank hp to be about 360. just get it on a chassis dyno and ask what the average drivetrain losses are and do the math and that should be pretty accurate as to how much hp you have on the engine

I would not put too much care into how much power the car makes in the engine.....I would be more concerned with how much it makes to the rear tires and how do I get it there.

But to answer your question 355-360 or so.

I would guess that you will be making around 370 flywheel.

I know that it sounds more impressive engine than wheels! Its like me saying I make 440rwhp. I could also say, figuring an average of 16% drivetrain loss, that I am making 506hp.

I just asked about how much it makes in the engine cause a few people at work wants to know how much hp it will add...and some of them don't understand the difference between hp to the wheels and hp in the engine. Thanks again guys...I really appreciate you taking time to answer my question!!

Is that counting the underrated HP? I thought the cars were closer to 350hp from engine. if you take 16% away from 350hp you get like 294hp to the wheels which is what A4s dyno about right?
