Alright, got my combo dyno'd. All supporting mods etc, E85, 3.12 pulley on a 10 percent od 4v with a v1 ti feeding it with a 8rib. I also only had the big ass MT 28x11.5 bias tires to put on it and its running 4.30 gears. She put down 677/530 at 11lbs. Tuner is the best in the business and im still battling belt slip pretty bad and this was acknowledged by the tuner himself. Boost was falling due too coolant, we got that corrected and the last 800 rpm looks like a sin wave now due to slip. You guys think this is all this blower is going to do or do you think I still have some head room? Blowers ratted for 950 hp. I know the 28inch tires and 4.30's are eating up some power how much who knows but the 28's are getting replaced for smaller street tires for the next dyno. Im obsessive with this crap and I will keep dumping money into her just want moral support in thinking it will be for something. Goal was 750+whp but reality is reality. Bigger blower time?
