Boost gain for hp

[GSX93DSM]

Somebody asked me how much hp you gain by ever psi you turn it up. I heard 8 and 10. I was thinking the same thing kind of thought about it but never try to figure it out. Does anybody know?

It all depends on yours setup turbo, supporing mods? A t88 and a t25 will have different hp gains even if your increasing the same amount boost.

Like a big 16g?

It still depends on your supporting mods because without decent supporting mods after a certain amount of psi you will tend to lose power rather than gain it.

100hp for every 10 lbs of air the turbo flows. Thats a general answer to make things easier.

Just a thought thanks I just thought I ask

As Black94DSM stated, it's generally accepted more or less that 1 psi = 10 hp.

You mean 1lb of air = 10 hp. Different turbos will flow different amounts of air at 1psi.

Woops, didn't realize my mistake. Thanks for the correction.

say i have an intake a 3'' turbo back exhaust, rest is stock, and i raise it to 16psi. what would you say my cars hp would be?

More than 1, less than 1000.

Every car is different. We can't dyno your car for you in our heads. You could have 20psi of compression in 3 cylinders for all we know: Now your intake and 3" exhaust are totally moot points.

Trying to guess how much horsepower you have, will have, need, etc. or how fast your times will be, or who will win a race is considered bench racing. We don't do it here.
