take rwhp/.85 for manual

I like that, it gives me 603 at the crank and all this time I have been saying 575. How accurate is this formula? Thanks!

That's why I asked about the formula. I'm happy with the 575 number. I actually expected 480 RWHP out of my setup in the first place, I'm going to get another dyne run on a different type to see what I get in.

their is generally a 15% power loss thru the drive train. thats how you get the formula of rwhp/.85

Is it linear?

to find drivetrain loss percentage take the 426hp the car was supposed to make and compare that to what your car put down stock... then use that percentage to find what ur new crank hp is versus what you have now at the wheels. I wanna say mine was around 18%.

Lil progression of dynos... the numbers mean nothing unless you can see your gains!

This is one of the big debates ... I think the loss should be a static number. In my logic way of thinking, your loss will be determined by the mass and friction of the drive train. If you aren't making any changes to the drive train (anything aft of the crank) then mass and friction should be the same.

Using this logic, if you start with a rated crank hp of 426 and have a wheel hp of 362 there would be a loss of 64 hp through the drive train. Lets say you put a few bolt on parts such as headers, exhaust, cai and tune. Now lets say it's running 415 at the rears, logically the loss should be the same and you should be around 479 at the crank. The only way to 100% on your numbers would be doing an engine dyno before doing a chassis ...

First number is bone stock. Second number is after E-Force with 3.5 pulley, ADM CAI, Kooks complete headers and cat-back and a custom tune.




This is with a custom blower cam from JRE, valve springs and 65lb Injectors and a re-tune.
