Wheels and Tires From Street to Strip – Part III

Our drag race and street-strip wheel and tire series rolls on. This time we’ll look at the rubber part of the equation. Years ago, slicks ruled the roost in terms of drag race tires. You wanted to race? You ran slicks. But today, many popular racing categories mandate radial tires. Read More

Wheels and Tires From Street to Strip – Part II

In Part I we looked at wheel weights. And while weight is critical, something else is hugely important for wheel performance – wheel offset. The industry is filled with virtually any combination of wheels with specific standard or custom backspace dimensions. So what’s right for your car? Read More

Axle Essentials for Racing and Performance, Part IV

When you need new (quality) axles, how do you measure for them? While it sounds simple enough, more than one person has made a critical error when it came to axle dimensions. And in most cases, once you have them, you have them. But we have a foolproof method for measuring for axles. Read More

  In the past segment of our Axles 101 series, we looked at the material choices (and finishing options) for axles.  If you recall, there’s much more than meets the eye.  But that’s far from the end of it.  You see one of the most important factors when it comes to axle strength is actually […] Read More

Headers: Scavenging Games Part IV

Drag Race 101: Headers, Part IV Recall a few posts back,  when we mentioned formulas and software that can help to figure out header dimensions?  We’ll, we’re bringing you a couple of header formulas below and if you need to check out a neat software program that can do much of ground work for you, try […] Read More

What you’ll see is a pyramid of sorts – one that controls the flow of the departing exhaust gases so that they do not re-enter the primary tube and travel backwards into the engine by way of the low-pressure area.

Headers: Scavenging Games Part III

Getting a handle on exhaust speed is extremely important (exhaust speed is the determined by the diameter and length of the primary pipe). But it’s the not only critical component in a header. Read More
