How much boost can you get from an s-trim? Is 8-10psi unreasonable for a small head unit?Should I have any problems getting 430 to 450rwhp from a LT1 with longtubes and 3in. true dual setup?

Supposedly max is 20psi. I am running 9psi max at redline and am getting 480 rwhp on my LS1.

I've seen Mustangs run 19psi and put 560 to the wheels. That is plenty of blower to do 450

I have friends who have done 430-450rwhp with an S-Trim on LT1's, very doable. They ran anywhere from 11 to 15psi.

I made 533RWHP and 588RWTQ on my mustang with an s-trim. It was running around 13#'s on a 347 stroker.

I have gotten 8.5lbs after the throttle plates and FMIC on my 383, with very good heads, small solid roller (230/236, 112LSA), long tubes and full dual 3" exhaust. The blower is the V-2 SQ S-trim.

The blower hits its max rated redline (50,000rpm) when I hit about 6200 rpm, but I am overspeeding it just a bit with my engine redline at about 6500rpm.
