To verify the tremendous acceleration we were all agog about, we ran our S302 Extreme tester over the Dynojet rollers courtesy of Magnaflow Performance Exhaust.
The results were encouraging, with a maximum torque of 494 lb-ft, and max of 524 hp. Adequate, as the man from Rolls Royce used to say, and a real accomplishment in a 50-state legal, EPA ultra-low-emission vehicle. Furthermore, these maximums came after driving the car an hour and a half to the chassis dyno. The power was simply read out; no icing, extended cool downs, or other tricks were employed.
Magnaflow's wideband O2 sensor also showed the Extreme was running a rich 10:1 air/fuel ratio at wide-open throttle throughout the meat of the powerband. This is a point and a half richer than optimum for supercharged power, but protective against detonation--a requirement with a production supercar. So, even more power could be made from this combination should the driver be willing to carefully monitor temperatures and environmental conditions, which we highly recommend against in a street car.
As it is, the power curve is wonderfully linear and easy to drive, and the lie-detector Dynojet shows the Saleen power ratings are correct assuming an 18 percent driveline loss or slightly more power under ideal test conditions.
