At Atco Raceway in New Jersey, the Procharger was tested with and without the meth injection. Hauffe reinstalled the stock Brembo brakes and wheels with 275/40R-20 Nitto Drag Radials out back. The test weight was now over 2 tons, up to a portly 4,170 pounds (the supercharger and meth equipment added over 120 pounds). At 4,050 pounds the best pre-ProCharger e.t. was an 11.81 at 119.27. On this 92-degree day (29.81 barometer, 45 percent humidity), the best e.t. without meth (7 degrees timing) was 11.10 at 126.73 mph. On the best meth-injected pass (18 degrees timing), the e.t. was 10.92 at 129.99 mph. Using a Density Altitude calculator, the DA was 2,407 feet above sea level. Corrected to 33 feet above sea level for the track we ran, with an SAE corrected standard of 72 degrees, we could've (in theory) posted a 10.62 at 133.58. That's a gain of 1.19 second and 14.31 mph, making it easy to understand why a ProCharger Intercooled system was Hauffe's power-adder of choice.
