Once the Tune Time Performance 2010 Chevy Camaro SS broke into the 11s by swapping on a set of Mast Motorsports CNC-ported Black Label heads (Feb. '10 issue), the potential to move massive airflow through the motor became possible. In "The First Push" (Oct. '09), we used a Mast Motorsports cam (.573/.588 lift, 220/234 duration, 116 LSA), along with SLP headers and exhaust. All the above bolt-ons would help make the 6.2 L99 more capable of expelling the additional atmosphere we intended to pump into it. When adding a forced-induction system (turbo or supercharger) it's possible to add well over 100 rwhp. For those following the progressive push of the Tune Time Performance '10 Camaro SS, in this episode it gets blown-safely.
The power-adder chosen was ProCharger's new '10 Camaro SS High Output Intercooled System. There are four available superchargers (P-1SC-1, D-1SC, F-1, F-1R) to choose from, along with the choice of three drivebelt systems (8-rib, 12-rib, or cog-driven). In the middle of the mix is ProCharger's D-1SC supercharger with the 12-rib beltdrive system. This was the logical choice considering the mods done so far. For even more stealth, we opted for the new helical gearset option for a significant reduction in supercharger noise levels-the car next to you won't hear your supercharger.
Right from the introduction of the new Camaro, ATI was there, measuring and designing its HO Intercooler system kit. All of its homework paid off to make for a perfect fit and easy install. If you have a bone-stock LS3/L99, or one with minimal modifications (exhaust, air intake), the P-1SC-1 head unit is recommended and the stock fuel system is sufficient (though larger injectors and a fuel pump booster/amplifier is extra insurance). Since the Tune Time Camaro has a host of mods, upgrading the fuel system (larger injectors and rails, dual in-tank pumps, adjustable regulator, return system, pump voltage booster) became necessary to prevent lean conditions, which could severely hurt the LS engine. Tune Time keeps a close watch on the air/fuel (A/F) ratio during dyno pulls and tuning and will lift-off the accelerator if any lean conditions are evident.
Initially there were issues with high inlet air temperatures on the dyno, along with lean A/F conditions. The Tune Time crew worked them out by adding methanol injection and upgrading the fuel system. Once sorted out and dialed in with a safe tune, we witnessed a monster power increase. Then we hit the track for dramatically lower elapsed times.
