LS2 Intake vs. TPiS Modified LS-6 Intake
The intakes were tested on a mild built streetable 412 cid LS2 with our TPiS 1-3/4" headers and TPiS calibration. The test was done back to back on the same day with all variables staying consistent through both tests. The only thing that was changed was the intake manifold itself, and the stock LS2 throttle body was used in both tests. At peak horsepower at 6200 rpm on both configurations, our intake was 43.6 hp bigger and peak torque was 28.1ft/lbs @ 5500 rpm. The torque and horsepower figures are bigger throughtout the entire rpm range. A huge gain.
