more boost = how much more hp?
 

for every boost you turn up on the vj-20 turbo, how much hp do i gain? so its ~180 at 8psi...

$#@$#@$, ok lemme be more specific, every time i add more pounds per square inch of air (PSI), for every one more i add how much hp do i gain? :rolleyes: :D

well i dont know if this will help
i know someone that has an 98 integra, so far the've done the ls/vtec and installed a turbo along with internals...blahblahblah
anyway, the place that installed it for him said that for about every psi you go up, you get about 3whp

I got my copy today!!! After Amazon kept on saying the order was gonna be delayed, I just went to borders and bought the damn thing. ($10 more though :( )Gonna get crackin' on it soon :D

was i suppose to know corky bell was a friggin book? everyone always bitches about posting similar threads, i thought you were just bitchin at me to search for that thread. wish everyone wasnt on their period when they reply to posts.

it's chill, ill have to take you for a spin in a few weeks when i move to bradenton, is that close to you?

:eek:

That depends on how fast he wants to go. ;)

If you're past a turbo's efficiency and continue to increase PSI, you will actually lose horsepower. All things being equal, with a small displacement engine, small turbo, etc, you may see 10-15hp per PSI, but as previously stated it DEPENDS :)

yah, 14s as high as im gonna go, when i turn it up ill today ill see if i can feel anything.

"for every boost you turn up on the vj-20 turbo, how much hp do i gain? so its ~180 at 8psi..."

there's this universal equation that seems to give you a rough ballpark figure.
i have the 1.5L engine that's rated at 92hp. so if i wanted 6psi running on it, i would like to figure out how much hp i would be making.
1) 6/14.7=0.408
2) 0.408+1=1.408
3) 1.408*92=129.55hp


((desired-psi/14.7)+1)*(n/a rated hp)=final hp

thats closer to what ive heard... usually bout 10 hp per psi on a 4-cylinder... one of my frenz is a turbo GOD (and sellin his evo8...) lots o shit done to this one, and hes very soon throwin a gt 35/40 on his "Crotch-Rocket Killa" 1st gen rx7 gsl se... cant WAIT to see this thing run... :D :eek:
