Engineering dollars are critical to part design, and the companies that spend them in the right places are oftentimes rewarded with a ‘must-have’ part for a particular competition level. That’s what Comp Cams is betting on with their new Elite Race Solid Roller Lifters, as they have come up with a clean-sheet design after quite a bit of time spent on research, development and tons of testing. The lifters are designed to hold up to just about anything, and a high-RPM race engine is where they are happiest.


Depending on who you speak to, we lose 10- to 20-percent of our torque due to friction losses in the drivetrain. Naturally, no one likes losing torque after spending so much money and working so hard to create this rotating force. This is, after all, the force we use to move the car and no matter which class you run, the name of the game is to move the car. So if we’re going to be good racers, one of the many questions we must ask is, “What can I do to reduce torque loss due to friction in the drivetrain? In this article we show you a few ways.


Drag racers have had a good problem for the past few years – horsepower, and lots of it. That’s what it’s taken to get some of the heaviest door cars into to sub-7-second range. The advancing technologies in fuel injection systems, digital ignitions, and overall engine design have made horsepower not only easier to obtain, but also easier to control. It seems in just a short few years, door slammers have become brutally fast to the point of surpassing the mandated chassis certifications. The problem was, there was not an SFI spec to “allow” some of the quicker/heavier cars run legally, that is, until September of 2009 when the new certification “25.3” was introduced. Let’s take a good look at 25.3 and what it means to you.
