Topgunz - air to air upgrade

welp i can say, dont buy the low to mid range impeller.
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.

Crap where'd you get this impeller from? I have a low mid range impeller from SCR that I haven't put in yet.

mines from SCR too. its really a different car then before, its more usable on the street, and the power comes on way sooner. i was just hoping for better numbers uptop but oh well!

What pulley setup you running and what do you top out on boost?
