Hello Mike, I have a ton of Experience with Centrifugal Supercharging using Vortech Superchargers since the early 90s.
We currently have an LS3 Stock Long block that puts down 800 RWHP on 100 octane unleaded race fuel, owned by Bigdog.
Vortech YSI supercharger
Vortech optional Cog drive
JRE Rough Idle blower cam
2 inch long tube headers
Magnaflow 3 inch exhaust.
1000 cc Injector Dynamics injectors
ADM dual fuel pump system
JRE custom Tuning.
Centrifugal superchargers are Easier on Parts as the boost is Linear with Engine RPM.
We have Hundreds of supercharged cars running around with 6-10 PSI for years and years drag racing and daily street driving.
Give me a call and I will Hook you up, I have a Polished V3 Vortech system in stock.
GQ4life has about 40,000 miles on his and He is NOT easy on it by any means
