Balance of Power

Balance of Power

Harmonic Balancer Types and Tech. It’s easy to underestimate the cost of a deficient harmonic balancer. But they can have a profound effect on the fortunes of the able race engine—a natural enemy of crank and bearings. With the engine running, camshafts and crankshafts vibrate torsionally (in twist) and, as the saying goes, for every action there’s a reaction. Camshafts are affected by the forces related to the opening and closing of the valves while crankshafts by the combustion events. Each time the cylinders fire, torque is imparted to the crank, causing deflections—twisting it as much as 2 degrees. All of this partially complicates the timing of the valve openings as well as the cam and ignition timing to say nothing of the oppressive conditions in which the crank operates.

Garlits talks tire shake…

Garlits talks tire shake…

with Prudhomme, Austin Coil, Mongoose… “In my heyday, to deliver the perfect drag racing run we raced a very fine line,” asserts Don Garlits. “If you had the exact right size tire for the weight of the vehicle and the clutch set exactly right for the horsepower of the vehicle and a track surface compatible with the combination, you could make a perfect run. But if the tire is too big it will shake. Read the full story courtesy of Drag Racer...
Pedal Performance

Pedal Performance

Enthusiasts with manual transmissions might know whether their clutch release mechanism is operated by cable or by a hydraulic bearing. But if it’s the latter it’s unlikely they could tell whether the bearing operates in constant contact with the clutch fingers or intermittently—that is, operating only when the clutch pedal is depressed. More interestingly, what would lead a manufacturer of high performance hydraulic clutch bearings to adopt one style over the other? Read Ram’s article on the proper way to install hydraulic bearings (courtesy of Fastest Street Car). Ram also provides an excellent video of understanding factory clutch hydraulics in late model vehicles – view the video...
Tech tips for steering in the right direction

Tech tips for steering in the right direction

If you aspire to own or build a great rod or replica, don’t take the positioning or the proportions of the steering column assembly for granted. A number of variables are involved in creating a comfortable setup, including the cockpit shape and seat location, particularly seat back tilt and cushion height, as well as steering wheel design. The rim’s diameter, and whether in dished or flat form, along with human proportions, all come into play. Read ididit’s story on what to consider before ordering and installing a steering column (courtesy of ReinCarnation...
What is a good clutch?

What is a good clutch?

There are several schools of thought on the question of what constitutes a good clutch. But first there are two separate strands to this narrative that need to be addressed: street or track. It’s key to distinguish whether the car will be used mostly for high-performance street-travel or for track use and its purpose needs to be decided. In either case the clutch has to transmit the car’s horsepower and torque and a stock clutch assembly will flounder in thermal shock and abuse, even in a slightly modified car.

Labor of Love

A supercharger with a low-boost fix and how it was almost never made. Published in the July issue of Power and Performance News In their delivery of instantaneous power, superchargers flourish when compared to turbochargers. They suffer no turbo lag. Beyond this there is now a street-performance centrifugal supercharger that combines this asset with a further dazzlingly effective characteristic. Commonly, the boost range of traditional centrifugal superchargers is initiated between 3,000 to 5,200 rpm. But Grand Rapids, Michigan specialists, TorqStorm, has taken a further leap forward by inducing boosted power at around 1,850rpm—and it continues to generate it all the way to 6,500 rpm. This masterwork is accomplished mostly by clever …Click here to read the full story.      ...
