johnc Posted April 28, 2003 Share Posted April 28, 2003 For all you drag racers out there, a horsepower tip from Gary Penn the head of General Motors Performance Parts (as stated in the latest issue of Circle Track Magazine): "At the drag strip, we actualy run our [race] engines out of oil at 1,000 feet and run it with no oil pressure across the finish line at 7,500 rpm. The pump has it all in the top of the engine at 1,000 feet because we only run 3 quarts of 0W-10 in the motor. That frees up a few horsepower because nothing is going through the pump, it just cavitates. Plus there is no oil in the crankcase so you don't have any windage. Even though the engine is running for about two seconds with no oil pressure, we really aren't seeing any undue wear. That's a testament to the quality of synthetic oils out there today..." Either you drag racers are sadistic bastards or this guy is trying to sell a lot more GM performance parts. Quote Link to comment Share on other sites More sharing options...

Mike C Posted April 30, 2003 Share Posted April 30, 2003 I have a friend whose engine builder talked him into same thing. He had a 434 small block in a '67 'vette rag top. About the timing lights, the motor locked up and caused the car to spin.... destroying the motor and causing significant damage to the car when the front hit the guard rail. I don't know about you, but compared to the pain suffered in the complete loss of a $10k small block and ANOTHER $10k in damage to an expensive car, even "significant" HP gains seem anticlimatic. So it seems he may be trying to sell more GM engines! Or he owns a body shop. Quote Link to comment Share on other sites More sharing options...
