Title: What is the Calculation for Air Mass Intake to get BHP
Post by: vRS Carl on March 11, 2010, 12:22:55 pm
As per title what calculation do you use for a K03 turbo car to turn Air Mass Gm/s into BHP

Is it 0.85 or something else

Cheers

Divide by 0.8 should give you a rough idea.

This presumes that the maf cross section area is stock. If you have a larger intake diameter at the MAF then there is a cross-sectional correction factor to do first isn't there?

That means my car is astonishing then for a k03.

My Average g/s is 234 = 292 bhp. Pushing the limit of a K03

My Peak (and have the log to prove it) was 241 = 301 bhp which aint gonna happen on a K03 car.

I know it's rough but 301bhp aint happening on a K03 motor  :grin: :grin:

Out of interest how do i add logs on here or do i have to type them out?

I'm going to post up another thread to explain why i was doing this today but that is just proof that K03 Cars on stage 2+ REVO make more than 205 g/s  :P
