Hits 9 psi at like 5800 rpm, then it starts sliding off. at first we thought belt slip, but not slipping at all.

only hit 427 whp and 368 ftlbs.

I think this impeller would be suited better on a mustang etc.. after about 6000 rpm, the boost starts tapering off. it feels way faster then before, but i think thats cause its boosting sooner.
