The 6.0-liter V8 engine produces 361 horsepower as per the claims Pontiac makes. Two runs were made on the dyno and the readings obtained were 286.62 and 310.37 horse power respectively, the maximum value deviating 50 hp from the manufacturer’s claim. The results were spot on as the 50 hp difference accounts for transmission losses. Usually, the power measured at the wheels is about 15% lesser when compared to the power measured at the crankshaft making the claim valid and accurate.

Dynojet dyno was used to calculate the power output and torque values.
