So taking your car and measuring HP on a dynojet at sea level will produce
different horsepower than a calibrated dynojet at 10k feet elevation (the
dyno can adjust for the altitude, but what if the car's boost controller works with absolute pressure and not relative?
It was pointed out to me that if you do two back to back runs of the same car on the same
dyno the graph of the results will be
different.
Hot Rod says that this, along with
different engine management, means the Camaro has a thick torque curve, with the
dyno showing 350 lb - ft from 2,000 rpm up to a lofty 6,000 rpm, with peak twist occurring between 4,000 and 5,000 rpm.
