hi i came across this site on google

http://www.geocities.com/dynocenter/turbo.html

it says its a 96 LS turbo with no other mods listed. so im guessing its just a stock LS running turbo.

255hp/215tq

how many pounds of boost does it take to get that on a stock LS w/ turbo?

i know it can't be for sure but just a good guess anyone?

 

probably around 8 - 10 psi MAYBE 12

 

Psi is just a measure of pressure--not how much air is flowing into the engine. How much power you make from one turbo pressurizing the intake at 10 psi is not necessarily going to be the same as another turbo pressurizing the intake at 10 psi. The one which can flow more air at that pressure is the one that's going to make more power. How much power the motor makes also depends on intercooler efficiency, what sort of exhaust you have, etc.

That said with your typical T3/T4 applications available in the Drag, Revhard, etc kits on a properly set-up LS motor, 10 psi will yield around 230 whp given proper tuning. So for 255 whp figure like 13-15 psi assuming the rest of the setup is up to the task.

 

I'd say its more around 10psi. I have a couple friends who made 280whp on 12psi stock internal LS. They were also making about 230@8psi. It would all depend on who tuned it.
