In today’s video, veteran engine builder Richard Holdener is going to demonstrate the power gains that can be achieved from upgrading the intercooler.
The core has two jobs — to flow air, and to dissipate heat. The more air you flow, and the more heat that is dissipated, the more power your engine will make.
First, Holdener dyno-tests a 427 c.i.d. LSX engine. The result: 656 horsepower and 592 foot-pounds of torque.
Second, Holdener installs a new ProCharger D-1SC supercharger kit but retains the standard naturally aspirated, air-to-air intercooler. The result: 943 hp and 794 ft.-lbs. of torque.
Finally, Holdener upgrades the intercooler to a larger, high-flow cooler.
The result: More than 1,000 hp, and a 70 ft.-lb. increase in torque.
You should definitely check out the video to see what happens, how it happens, and to consider how your cooling system might be impacting your engine performance.
Well done production!
I wanted to have a look at free samples of college essays. I’ve found them on this website. They don’t charge for reading them.
