I've been daily driving e85 at this power level for 4 years and over 100k miles now. Vortech 3.48 pulley at like 8.5 psi max. High hp low torque. The blower doesn't come alive until 4k rpm, but if i'm banging through gears, I don't see below 4k. The stress on the motor down low is not that big of a difference than stock. Everyone scoffs at the vortech's torque when in reality it's the SC kit that makes the highest hp with the lowest boost pressure.
