To test the Plasma Booster's horsepower worthiness, we made the short trip to Coastal Chassis Dyno in Tampa, Florida. Owner Sam Lippincott had just recently opened the doors when we came looking for dyno time. Sam is also building a Real Street car for NMRA competition. Coastal utilizes an MD-250 Mustang dynamometer with a wide-band O2 setup to monitor air/fuel ratios.

The dyno numbers listed represent those of our 3g GT, which is what we used to test the Plasma Booster. While the engine is stock, it boasts an ATI-ProCharger P-1SC supercharger, a MagnaFlow X-pipe, and a Steeda side-exit exhaust. Sam informed us the car was running a little rich, but we didn't want to push our luck and try to get even more horsepower out of it. We ran two baseline runs and used the second for the "before" numbers. We did the same with the "after" numbers. Our tune-up didn't change between the before and after numbers. We weren't quite sure what to expect out of the Plasma Booster, but we were floored when we realized an increase of a solid 12 hp and 12 lb-ft of torque. There aren't many sub-$300 products on the market that will give a 12 and 12 increase in both horsepower and torque.

Dan Flowers at Idle Wild Racing tested the Plasma Booster on his naturally aspirated '01 GT, which features a cold-air kit, a Bullitt intake, and underdrive pulleys. Dan's GT gained 4 hp at the peak and 6 hp at 5,800 rpm, but the torque stayed the same across the board. Dan also reports an easier start-up and that his car revs cleaner with the Plasma Booster installed. He cites easy installation and great value as benefits of the Plasma Booster.
