It’s no secret that an open differential (fondly referred to as a “peg leg” in some circles) just doesn’t cut it in a high-performance application. Having one tire go up in smoke while the other does nothing won’t get you down or around the track in short order. That’s why spools and positractions are so common in motorsports.
When left you in the last article in the series, we showed how Van Steel (website: www.vansteel.com) stripped the C3 Corvette rear end center section, in preparation for blueprinting along with the install of 30-spline stub axles (Chevy calls them “Side Gear Yokes”).
When we left you the last time around, we presented a dozen different fast facts on connecting rods, crankshafts and associated components.
There are a number of different ways to install pistons (with rings, obviously) and connecting rods in your engine. Different builders take different approaches.
Pin the throttle, dump the clutch, hang on. The car hooks and rockets forward. Then, just as you’re watching the tach as it bends toward the redline, the thing noses over
When many aftermarket manufacturers build a “fits-all” universal” part, they really have no idea what your application may be. It’s up to you to figure out how to mount the component. Common examples of these fits-all pieces might be fuel filters, fuel pumps, accumulators and so on.
Assume you have a custom-built car you’re working on. Assume you have an engine. At some point you have to mix the two together. No big deal right? Probably not.
It’s no secret my background was drag racing, and I’ll be the first to tell you that most sharp weekend warriors (and even many seasoned racers) don’t like taking all of their tools to the track.
The truth is, if you’ve ever drilled a hole in something, bolted it down, then had the darned thing break or fall off a few days or miles later, you’re probably looking at an article of interest.
When we last left you, we were deep into the workings of MSD’s entry level Atomic EFI. If you recall, we showed how simple the system is to work with, and how easy it is to install.
