Yes this is on e85 and about 19.5 for the timing i believe. I had a stock Stegi ported blower before @15lbs with longtubes making a touch over 600. The short time i have behind the wheel of this now, i say it still pulls very hard down low but the top end it crazy.
Results are in on my 07 GT500, 748whp and 729tq @19lbs of boost and 770whp and 768tq @ 21lbs of boost. Car has Innovators west 15% lower and 3.25"(19lbs)/3.0"(21lbs) upper pulleys Was at the edge of the stock maf @ 21lbs so will be running the 3.25 upper with 19lbs for the time being.
Yea, I bought the kit a while back on a previous Lethal sale. It looks to be of nice quality. Recently got the injectors too and the Whipple should be on it's way soon. Will start working on the car any day now and I hope to have it tuned as soon as the weather is nice this spring
