We have proved them wrong! You the owner-operators of North America, Alaska, Hawaii, Australia, New Zealand, and Switzerland, along with us at Pittsburgh Power Inc.
I loved and still do enjoy working with my hands. However back in 1977 diesel engines were dirty, noisy and slow. A small cam NTC 350 was a big hammer and this was the start of the Big Cam NTC Cummins. In 1977 nobody no one gave extra fuel to diesel engine, but I did. I realized that most owner-operators were gear heads just like I was and if I could drive a high performance Corvette as my every day car why couldn't an owner-operator have a performance diesel engine in his every day truck.
We talk about this subject quite often and continue to learn more about the value of fuel and exhaust flow while testing trucks on our new Taylor Dyno. For instance, our ported and ceramic coated exhaust manifold flows 20% more exhaust, lowers the exhaust temperature by 125 degrees and improves the spool up time of the turbocharger.
What we have recently learned on the C-15 Caterpillar single turbo engines is coupled with our High Performance Cat Turbo the engine gains about 100 horsepower.
We are NOT adding any additional fuel just eliminating restriction and turbulence and the net gain is 3.12 horsepower per pound of turbo boost. That is an incredible gain of power just by changing two items on the engine. Keep in mind these trucks that we test already have our high flow quiet performance mufflers and most of them have the Fleet Air filters already installed. Every day we get back reports from owner-operators that install the manifold and turbocharger at the same time and they tell us they have to learn how to drive their all over again because of the power, rate of acceleration, and response and know we know why they feel such a difference, they have just gained 100 horsepower.
