What’s the future of engine technology? While most of the focus has been on electric engines, a Canton, OH company is convinced the future of engine design actually lies in the past. Radial Engine Innovations (REI), Inc. has begun developing a modern-day version of the radial engine called the RA-92 that traces its roots to pre-World War II
First- and second-generation Camaros and Firebirds (1967-81), along with 1968-up Novas and other GM X-body derivatives, were built with a big, bolt-on front subframe assembly. This huge subframe was originally held in place with only four rubber and steel cushions for the actual body and two smaller rubber and steel cushions for the radiator support. The rubber
The manual transmission is still the preferred gear-changing option for many high performance enthusiasts. For some, though, the manual tranny remains a mystery. And even for seasoned stick shift drivers, the science behind the inner-workings of the manual transmission can be somewhat murky. That’s why we’ve decided to pay if forward by sharing this 3D animation, which
New engines aren’t cheap. And rebuilds can be costly and downright time-consuming. It’s no wonder unfamiliar sounds from our engine compartments can cause immediate concern. Seriously, anything except “vroom,” “roar,” and perhaps the whine of a supercharger are completely unacceptable. The key is figuring out the source of odd-ball sounds, so you can address any potential problems
Big cars need big brakes. While a common drag car might weigh 2,400-2,800 pounds, today’s street-strip machines can easily weigh more than 3,500 pounds. Often these heavy, fast cars tax the rotors, and the thin drag race-only pieces can become cracked or warped due to excess heat. Plus, the small, drag race-style calipers can flex at the
It’s one of the most-searched automotive questions on the internet. It’s also one of the most-common reader questions we get here at OnAllCylinders. “Why won’t my battery hold a charge?” Truth is, it might not be your battery’s fault at all. It could actually be a problem within your vehicle’s charging system at large. We realize
As we told you in Part 1, there is a formula to creating a stroker engine. Bore size, overbore, crankshaft stroke, and connecting rod length must work together to produce the desired displacement without creating clearance problems. That’s why we worked with the experts in the Summit Racing technical department to do some of the essential math
Fuel pumps come in a variety of designs. In the most general terms, you can choose between mechanical, belt-drive, and electric (inline and in-tank) pumps. We wrote an earlier post discussing the differences between mechanical and electric fuel pumps and another on how to choose the right size fuel pump in terms of volume and pressure. One
Your tires might be telling you something. Are you listening? The condition of your tires could warn you of premature wear or be a sign of issues in other areas of your vehicle. You may simply need to add more air pressure to your tires, or you might need to have your suspension system checked
Turbocharging continues to gain popularity. But there are still a few areas of a typical turbocharger setup that remain fuzzy to turbo newbies. One of the most common misunderstandings involves the basic difference between a wastegate and a blow-off valve. So here goes… What is a Wastegate? A wastegate prevents the turbo from creating too much boost. Once
