Spec Sheet 700hp LS2
Running a mild Lunati Voodoo cam, a set of Trick Flow CNC-ported LS1 heads, and a FAST LSX intake, the Vortech supercharged LS2 produced 710 hp and 610 lb-ft of torque. The impressive thing about this supercharged combination was the fact that all this power came at just 7.7 psi of boost.

Running the LS2 crate motor from GMPP, we added Trick Flow Specialties CNC-ported LS1 heads, a small Lunati VooDoo cam (212/218 duration), and Hooker headers. Though the Vortech supercharger kit was equipped with an air-to-water intercooler, we also ran a Snow Boost Cooler water/methanol injection system to further keep detonation in check. This also allowed us to get more aggressive on the timing and air/fuel ratio to maximize power production. Running a peak boost pressure of just 7.7 psi, the supercharged LS2 produced 710 hp and 610 lb-ft of torque. Note from the curve's shape that the power was still climbing at 6,500 rpm.
