Stillen SC Build 500 WHP?

EVOHUNTER · 09-12-2012, 08:39 AM

Is it worth getting the impeller and shims from 928 motor sports? or just do the cog set up?

The Impeller works, I read a ton of stuff on it, Mr.Sqeeze made power with it and the cog set up, Not sure how much soon the PSI comes in but the 360 WTRQ is nice, I got mine from Vortec cause it was there for the warranty work.

With the cog and impeller upgrade? Squezze did, Ran out of MAF @6500. The injectors will work but 90-95% duty cycle. Maybe one of the other guys will chime in on the duty cycle also.

Maybe with the cogs +2 PSI you are ok? The impeller should be another 2 PSI and boost comes in sooner in the RPM band and more PSI then also, I was reading over on the Cobra forums, Guys were seeing double the boost at 3k, " Say they where seeing 3 PSI @3k after the did the impeller they woud see 6PSI at the same 3k"

You probably didn't have a problem because your still on the stock impeller that comes with the blower . It flows less CFM that the SI upgrade from vortech and 928 impeller . What are your numbers I would love to see a graph .Also are you using the same cog combo I used ?
