How fast at 14psi?

[Turbo_Lover]

I just put a grianger type device on my GLH. How much faster will I go? (Im putting a new rocker arm on it right now. Not gonna down shift in to first when im trying to go to third ever agian! ) Any ways, just wondering about it before i get the Omni back on the road/track.

If you were just running stock boost before, you'll probably pick up at least 25hp. You'll feel it for sure.

If you haven't upgraded the exhaust you'll see even more. I ditched the cat (choke city) and installed a 2 1/4" non mandrel cat back exhaust and picked up 3 mph (30 hp) with stock boost.

if your GLH isn't intercooled, be careful!...93 octane minimum too.......i ran a 14.5 on 14 psi.
