So your thinking... ok, ok, enough chatter... show me the numbers! Six cars and seven hours later the results were in. For peak horsepower and torque, APR nosed ahead of the field and put out a pack leading 303.1 horsepower and 302.1 lb-ft of torque. Most of the rest of the field was pretty tightly bunched right behind APR (within 10 hp and 4.9 lb-ft torque of the best numbers) but there has to be a winner, right?
The big surprise of the day was AMD coming in a distant 6th place, behind the stock car, making a whopping 31.7 hp less and 2.8 lb-ft torque less than stock--a real head scratcher considering the upgrades to the car.
OCT was the only software that did not
lose torque compared to stock over the RPM range. While
the APR car had a peak torque higher than any other car,
it was under the stock torque curve between 4000-4700
rpm. GIAC had a huge deficit in torque between 3000-5000
rpm compared to stock. Even though it's peak torque was
at 3000 rpm, it could not hold the power across the
3000-5000 rpm range. AMD was way below stock torque
output during the entire rev band. Both OCT cars stayed
well above the stock torque curve, consistently.
Seven dyno pulls were made with AMD with the later runs yielding the best power. Only two of the seven runs are included below.
The B6 shootout was an interesting event to participate in. All the cars were pretty consistent. The ice cold temperatures and cooling fans helped keep the cars from heat soaking run after run (some even performing better after a pull or two). Even under the harsh conditions presented by a dyno the 4.2L V8s just kept twisting out power without fuss.
