Eddie fixes downside of serpentine belt kits

By Vic Moore: I often wonder how Joe Rode, the able manager of Eddie’s Motorsports, will cap his career. Why? Because he’s constantly observing, endlessly productive. Tall, lanky even, with a physique that doesn’t vary too much, I remember studying him on foot along a crowded corridor at a PRI show some years ago, his strides were inordinately long, he hugged the wall because it was the quickest path forward through the throngs and he traveled three times faster than anyone else. Rarely sharp or opinionated, his voice is usually peppered by a compliment or two, but it is his substance that makes him special—a calling that requires him to get things done. This week he has unveiled Eddie’s most important new product in over a year: eight-rib serpentine pulley kits. Cleverly, this pulley kit is fully independent; it doesn’t rely on various cylinder head mountings. Instead it uses the water pump’s mounting base for consistent trouble-free installation. Here are details of the kits’ merits and its appearance when installed: S-Drive Plus Eight-Rib Serpentine Pulley Kits from Eddie Motorsports › 33% greater contact patch than standard six rib kits › Improved belt traction limits slippage in higher horsepower applications › Handles increased torque loads of 33% more than six rib › Greatly reduces Span Vibration(belt whip/belt waves) › Improved belt life Eddie Motorsports offers the most complete serpentine pulley system on the market. One part number provides everything you need to embellish the front of an engine including all accessories, fasteners, pulleys, and belt. – Simple, trouble free installation using simple hand tools – No need to chase pieces...
Motown LS: Unfamiliar hybrid

Motown LS: Unfamiliar hybrid

By Sam Logan: What’s the motivation for adapting LS cylinder heads to a small-block Chevrolet engine? Why not just go out and buy a used LS-series? It’s a modern power unit; it’s bestowed with high flowing heads, it’s readily available and it’s affordable…all the benefits you could desire. Except there’s a catch—the inconvenient fact is there’s a ton of work required to get it installed properly, coupled to appreciable expenditures. If you are empowering any pre-1990s Muscle car with an LS-series engine it is usually not a simple swap. And it’s not just exploring engine and transmission mounting solutions and clutch actuation, but there are EFI and ignition considerations, a fuel system design as well as numerous cooling and engine accessories questions to resolve. The fact is that mounting a pair of LS-series cylinder heads on a small-block is a much more practical solution. Likely, the most interesting new engine for 2016 will be the Motown LS. Under the insightful command of Dick Boyer, the architect of the last year’s 454 Man O’ War Ford block, World Products committed to foundry tooling expenses for the production of such a hybrid. It is unique. Weighing 210lb and employing standard LS deck height, the Motown LS is a cast iron small-block that accepts LS-series cylinder heads. Boyer’s uncommon design made its first appearance in public at December’s PRI show. Available in two versions, a street-strip and a race variant, he had displayed the former although not yet tested. When tested the 427cu in engine generated just under 640hp at 6,400rpm. Not bad for a street-based engine. The drag race version uses...
New clutch concept for modern Muscle cars, dual- and triple-disc

New clutch concept for modern Muscle cars, dual- and triple-disc

For some time, Ram Clutches had been seeking lighter pedal effort on high performance clutch systems while maintaining adequate clamping loads but couldn’t devise a diaphragm pivot arrangement within the traditional steel cover assembly to achieve it. Though their current designs perform well, in this crusade they offered little potential for improvement, prestige or reward. So, to develop their new series of clutches for contemporary Muscle cars, they set about constructing their own billet aluminum cover assembly that resolved this problem and two others. › Revised mechanical ratio brings light pedal › Direct replacements for new Corvettes, Mustangs and Hellcats › Higher diaphragm fingers prevent over-center shifting issues › Straight retaining straps improve durability   Columbia, SC: Ram is announcing new Pro Street clutch systems. They contain their best-operating geometry yet. To date they are available for six contemporary Muscle cars (listed below). For a long time the mechanical ratio in most high-performance street-vehicle clutches has remained fixed. The clamping pressure within the familiar steel clutch cover assemblies has been adapted to adequate standards but the pedal effort is not always so. In addition, the conventional straps that secure the pressure ring to the cover assembly, though capable, have been susceptible when exposed to abuse—usually from violent downshifts or by missing a gear—and the height of clutch fingers was rarely optimum. Last year Ram embarked on developing new aluminum billet cover assemblies. Their principal purpose was to gain control over the positioning of the pivot points—the diaphragm spring fulcrum—and thereby attain the elusive lighter pedal. They also improved the layout of the pressure-ring retaining straps, which now adopt a...

Servicing Mass Airflow Sensors

Ray Bohacz is a journalist in the automotive field and author of CarTech’s book “How to tune and win with Demon Carburetion”. He is also a monthly contributor to Hemming’s Muscle Machines magazine. Additionally, Ray writes short articles for the agriculture industry and is featured in a series of videos as the SF (Successful Farming) Engine Man. His videos introduce brief, informative features which apply to both farm and automotive equipment. Most modern fuel injection systems employ a mass air flow sensor (MAF) that is located between the air filter assembly and the throttle-body. The MAF measures the air flow into the engine. This data is mainly used by the engine controller (ECU) to determine fuel injector pulse width. The MAF output is also combined in an algorithm with the outputs from the crankshaft and throttle position sensors to determine engine load. This influences both fuel and ignition timing. The MAF output will skew when coated with air-borne contaminants. This is how to easily restore its accuracy. Watch the...
Helpful tips you need to know about racing oils

Helpful tips you need to know about racing oils

Meet specialist Len Groom. By Freddie Heaney: Between a crankshaft journal and a rod bearing a film of oil resides in a space approximately the thickness of a human hair. In last year’s Pro Stock 500cu in V8 racing engines, crankshafts were spinning near 11,500rpm. In 2006 the V8 Cosworth F1 racing engine reached an astonishing 20,000rpm. Oil film operating in passages the thickness of a piece of paper prevented their parts from touching—as it is in most racing engines. Oil film, which is also referred to as an oil wedge, can be better understood if you consider a piston ring moving down a cylinder. When in motion, the oil begins to accumulate before the ring and forms a wedge-like shape. If severe, the ring can hop on top of the oil wedge, which breaches the seal between the ring and cylinder wall, causing blow-by of combustion gases. Though more difficult to visualize, the wedge effect is also present in the lubrication space between the crankshaft journal and the rod bearing. Its depth measures approximately 0.003in. Recently, at the annual MPMC conference where 100 racing parts manufacturers met the media, AMSOIL’s Len Groom was on hand, as intelligent a man as ever discussed synthetic racing oils. High quality racing oils, he explains, demand attention in several key areas in order to provide protection. Two of the most important areas lie within their film strength and resistance to viscosity loss under high pressure. “In fact,” says Groom, “when racers using our 15w-50 tell me they are running oil temperatures of 260F, I don’t get too concerned so long as the...

He begins: It was the same sound you hear when you pour too much lighter fluid on the charcoal as you’re preparing a Fourth of July barbecue. A giant “whoosh” followed by a flash of flame. Except it was a thousand times louder. And it wasn’t charcoal that was on fire. It was me. Read the full article...
