I don't know how much HP, my original setup was designed for 707 WHP. I'm now on a D1X with a 4.5 pulley 7 PSI. I would assume I'm at 650 to 700 WHP. I have NOT run E85.... with the new ZL1 pump. My car is having drivetrain upgrades...

When the ride is back on the road.... I can finish the tune on E85 with the 4.5 pulley.
I have a 4.5 pulley 7 PSI on a full built engine
I have a 4.0 pulley about 10 to 11 PSI on full built engine
I have a 3.85 pulley about 14 to 16 PSI on full built engine, closing on peak impeller speed depending on cam in the engine say 6800 RPM... calculations posted before... going from memory. It maybe a 3.75 pulley I'm not at home...
