boost calculations

ok i got very boared at work during training so i started to do some math

based on the equal CFM's and RPM's

150whp @11lbs
187whp@17lbs
252.52whp@25lbs

thats calucating a 25% drivetrain lose for the ol dsm
so if more or less 200 stock fly horse wheel power how does that sound

also if you have the true equation plaease post it because i need somthing to do the rest of the week

thanks

i figured it to be about 185whp when i was running it, so id say your calculations are about right, but not the final one at 25psi...you begin losing efficiency, id say 220-230 range.

as i said cfms being equal to hp ie doesnt mean the stock turbo just the most efficent turbo for the hp

at 20psi on the 14b, you should be very close to around 280whp.

Evos with a few mods are putting out numbers around that level. By your numbers, I should be running high 12's in my nearly stock dsm at 20 psi. I haven't taken it to a track, but comparing it against a bpu supra I've ridden in that should be running at least low 13's, I'm not running any 12's. Would be nice though.

hartman, are your number based on a basically stock car with mbc and K&N? I've been looking for a good estimate of what power level basic mods should put out, those numbers look pretty good. I can't wait until I can get a 3" o2 elim dp, that's got to be good for at least 20-30 hp over stock, running open downpipe through a cutout

yes im basising this on a basically stock car but as i said as i increased i did the math with equal cfms per amount of boost
