HR L99 to LS3 Camshaft Dyno Numbers and Video

A big thanks to the guys at Heintz for all their work and professionalism. The car actually runs the way I was expecting and just sounds plain mean. Videos are posted in the video section. Now to get it to the track and see how it does.

Run down of the modifications installed by Heintz Racing: Vigilante 3200 Stall, 160 T Stat, ATI Underdrive Pulley, Melling Oil Pump, C5R Timing Chain, Comp Trunion Upgrade, HR Custom Camshaft 22x 23x .58x .60x 113+2 LSA, Patroit .650 Valvespring Set, Hardened Pushrods, LPE L99 to LS3 Swap Kit, Tuning Via HP Tuners

Peak Gains with the addition of the cam were +63 RWHP and +20 RWTQ. The torque carrys way farther into the RPM range, and at times picked up around +60 ft lbs. Final numbers are 403 RWHP and 373 Torque.

Most underdrive pulleys depending on the % underdrive can net about 7-10HP. With the ATI, the balancer and dependability were more important than the small HP gain.
