As one of the final steps in the development program for the Supersport, the car was taken down to Road Race Engineering and put on their Dynapack chassis dyno to accurately measure exactly what kind of horsepower and torque the GM Ecotec 2.0L engine is putting out in the current trim.  The results of the Dyno tests were outstanding!

We have been working with Trifecta Performance to develop a more powerful and reliable tune for the engine.  The dyno results show that we have achieved all of our goals and more.  The engine put out 293 rwhp at 5200 rpm.  The engine has a nice broad flat torque curve producing over 300 lb.-ft. of torque from 2800 to 5000 rpm with a peak of 339 lb.-ft. at 4100 rpm.

We have established a shift point of 5700 rpm and redline of 6000 rpm so the stresses on the engine are low, insuring a long engine life span.

Thanks to Mike Welch of Road Race Engineering for the excellent dyno job!
