97 sr black top how much power should I see with 10 lbs on a stock turbine?
and should I adjust my fpr higher? Is anyone running 10 lbs whats your set up?

stock TURBO....and this has definitely been talked about many, many times.

So is it an S13 or S14 SR (does the valve cover have a slanted part toward the back?).

S13SR comes with T25, S14 comes with T28.

S13SR with T25 @ 10 psi, maybe good for 215 hp or so to the wheels

S14SR with T28 @ 10 psi, maybe closer to 245 hp to the wheels

just my estimates

I did 249 with my S14 SR20 on 9lbs hitting the speed cut in fourth.

Couldn't even begin to guess why. The car was running the usual walbro 255 with stock injectors and the pump failed ten days after this.
