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.

Update on new Hemi cylinder heads for small-block Fords

Update on new Hemi cylinder heads for small-block Fords

After twenty years of reporting developments in racing and performance parts, it’s useful to remember just how confounding it is to accurately predict what new designs might appeal and what might not. But the response to our recent account of the new small-block Ford Hemi cylinder head from Hammerhead Performance Engines was unprecedented. It inspired tens of thousands. Distinguished innovations and their inherent beauty, their complicated geometry and the precision of their machined parts are the things that motivate us all. This being the case, here below are a few of the latest photographs illustrating the assembly of the 427cu-in block on which the first Hemi heads will be attached. This week, December 8-10, Greg Brown, the product creator will debut the new heads, rockers, valve covers at the 2016 PRI exhibition in Indianapolis. His exhibit can be observed at the World Products booth #1343. Contact Greg at: hammerheadperformanceengines.com Read the original story...
Androwick on Oval Track, Pro Stock, a new racing head, an intake and a vacancy

Androwick on Oval Track, Pro Stock, a new racing head, an intake and a vacancy

By Sam Logan: In the past eight years, Mike Androwick’s reputation along with that of his son, Mike Jr. had become synonymous with designing and preparing race-winning cylinder heads for big-block Super Dirt Series championship winners. His heads have graced those winners in 2013, ’14, and ‘15. And this year, as an associate sponsor, they won 5 track championships and finished 2nd 4th, 5th, 6th, 7th, and 9th in the Super Dirt Car Series. Year-to-date his company, Mike’s Racing Heads based in Concord, North Carolina has supplied 150 cylinder heads to these racers. This being the case, you might conclude he had rendered every other racing head market as inconsequential. Except he didn’t. Success boils down to passionate effort and much of Androwick’s passion has been riveted on Pro Stock since boyhood. This year he and his team assisted the Denver, North Carolina-based Gray Motorsports in designing and preparing heads and induction systems for their NHRA Pro Stock campaign. And the results? Three number-one qualifiers, three wins, two runners-up and 15 semifinals Creating successful racing heads and induction systems is a craft, part inspiration but mostly know-how and hard work, which reminds one of that wonderful Bob Glidden line: “All hard work ever did was to make you tired.” Still, when you’re in the shop from around 7am and remain there until 8 or 9pm you’d think the romance of your chosen career would gradually fade. Not so with Androwick. He still embodies the young man’s eagerness for learning and improvement. Displaying at booth 2332 at this week’s PRI exhibition at the Indianapolis Convention center, December 8-10, here are...
The anatomy of the supercharger or what makes it tick

The anatomy of the supercharger or what makes it tick

By Titus Bloom: Superchargers are magical devices. They increase the oxygen supply to the engine by compressing the air, thus increasing its density. Accordingly, the engine burns more air-fuel mixture and produces more power. In a centrifugal supercharger, the air is propelled through the compressor wheel and compressed in the diffuser—the thin passage formed between the compressor cover and the bearing housing—and in the volute or scroll where its kinetic energy is converted to pressure. All of the dimensions, including the diameter of the diffuser, diffuser gap distance, size and diameter of the volute, contribute to the degree of compression. In a turbocharger—exhaust-driven forced induction—the compressor wheel is powered by exhaust flow, but in the supercharger the compressor wheel is driven via a gearbox that takes its power from a crankshaft pulley by way of a drive belt. The gearbox accelerates the compressor wheel from engine speed to a point where the compressor operates efficiently.

Lightweight steering column for racing chassis & hot rods

Lightweight steering column for racing chassis & hot rods

At this year’s SEMA show held in Las Vegas, November 1-4, ididit, the Tecumseh, Michigan-based steering column specialist, won the Best New Street Rod/Custom Car Product award with their new ‘40 Ford special edition column, which also suits the Model A and the ‘32s. Beyond this, Marty Waterstraut, ididit’s national sales manager introduced their new production racing column called the Pro Lite series.  Designed for the Sportsman racer—drag racer, auto-crosser—the entire column weighs a tad over 5 pounds. “Some drag racing classes mandate street-legal specifications and, therefore this column is equipped with turn signals,” says Marty. It also accommodates quick-release steering wheel hubs, making it ideal for driving the car to and from the track. In word and deed this column is all about weight. The Pro Lite series, which makes a great first impression, is now available for the Camaro, Gen 1 and later, the Nova as well as several Mustang models. Current development plans include numerous other examples. Source Ididit Tecumseh, MI 49286 (517) 424-0577...
