Building a high performance engine is always an adventure. You never know how much horsepower and torque an engine will make until it’s on the dyno. And you never know how well the engine will hold up until it is put to the test on the strip, race track, street...
Boy, has life ever gotten complicated! Back in the late ‘60s and early ‘70s when Jim Kirby, Mike Kausch, and I were racing fueler Chevy funny cars, there were only about six American racing oils on the market. Three were produced by major oil companies (Pennzoil, Quaker State and Valvoline),...
When it comes to a productive engine test cell, the key might surprise you. While the dynamometer satisfies the core requirements, support systems are especially critical to delivering performance – on top of the fact that these systems can significantly reduce risks associated with health-safety issues. And for OEM dealer...
If you’ll recall, in the January issue, we got into the nitty gritty details of what makes a camshaft the “right” camshaft. In this issue, we’ll continue the education. Cam class is back in session! Remember the camshaft makes one complete revolution (360°) while the crankshaft rotates twice (720°) for...
Perhaps the most important property of lube oil is its ability to remove heat from a surface where two or more metals are sliding across each other. In much the same way as air flows around cylinder head fins to remove heat, oil flows through a bearing and removes the...
On a basic level, fuel injection just looks really cool. The intake on a fuel injected power plant is the most visible part of the engine while the ram tubes, injectors and fuel lines make it look intricately sleek. With recent developments, simple mechanical fuel injection (MFI) is also useful...
Flow…that magical, mystical word that is seemingly carved in stone anytime the discussion topic turns to performance cylinder heads. Whether you are a seasoned veteran in the engine wars or finalizing the specs for your first ever build, it is virtually impossible to avoid it. The flip side of that...
