Well just got back from the dyno, had the car tuned with the new vortech 3.3 at Mid Atlantic performance by Mike Rousch in richmond, VA. I didnt know how much boost it was going to make, it had the 4.25 upper with a 4lb lower. Well it made 24 psi and being on 93 octane timing was kept at 15* and tune was conservative given the boost. With Mike dialing in the air fuel and 2 people sitting in the trunk to keep it from spinning it laid down 725hp 617tq SAE, 755hp 643tq uncorrected. I think the 3.75 pulley and race gas would be crazy!
