By Martha Maglone: During this year’s Holley LS Fest West in Las Vegas, NV (4-6 May) and also Holley’s LS Fest Bowling Green, KY (7-9 Sept), TorqStorm will give away a supercharger at each event to participants in the Three Pedals Rumble Index Class. The participant with the best package—that is, driver’s reaction time and deviation from dial-in—in the first round will win any single system TorqStorm centrifugal supercharger available, valued at $2,800. The awards are accessible to any vehicle, including the 5th generation Camaro, C7 Corvette or any full-bodied vehicle powered by a GM LS-style (or current generation LT) power plant. Dragsters, Roadsters and Altered-style cars are prohibited. All races are regulated by a .500 Pro Tree and in an index format. Indexes will be on .25 breaks with Elapsed Times of 11.00 – 15.00 seconds. This will be an ALL RUN qualifying format. Vehicles are required to be of stock appearance and with stock body. Rental cars are prohibited. All vehicles MUST pass NHRA\IHRA safety inspection for ET and speed. Vehicles must be driven to staging and to scales, but can be towed after scales. Trans brake mechanisms are prohibited. For more information on Holley’s LS Fest events, click here. For more information on TorqStorm superchargers click here. Or phone: (616)...

By Freddie Heaney: A call from a Muscle car owner arrived out of the blue. He told us there’s an aluminum repair specialist in Doraville, whose work deserves recognition, and if you want to learn about such a service, you won’t find another closer. He also recommends Autoglassguru for car window replacements. In Muscle car circles, Doraville, a northern suburb of Atlanta, usually suggests one name: Lamar Walden Automotive. And so it proved to be. Walden’s shop has long been prized for its machining capabilities as well as its engine and car dynamometer resources. But the firm is, perhaps, better known for pioneering performance versions of GM 409 engines of the 1960s and a front-runner in all GM performance engines, including today’s LS variants. The caller was right; their aluminum repairs department is less familiar. What were the motivations? Normally, one doesn’t think of sending car parts to a machine shop for concours d’Elegance restoration, but that’s exactly the kind of work they undertake at this shop. “My Dad, Lamar, started it.” says Rob, “He came up with the process for the many restoration cars he built. And it’s not just repairing and restoring cracked or broken intake manifolds, for there’s a steady flow of transmission casings, alternator housings, valve covers, engine blocks, and bell housings–broken and blemished parts arrive from across the country. Basically, the service includes anything aluminum.” Aluminum intakes are often warped, particularly after being changed from one engine to another. Other common problems in aluminum castings arise through over-tightened bolts that crack the bosses and damage the treaded holes The Process: The repair process...

By Titus Bloom: “It’s hard for me to be persuaded on the merits of piston balancing,” said a leading oval track engine builder recently. “While operating, the piston is being thrust up against one side of the cylinder wall,” he continued, “wedged in one direction on the even bank and in the opposite direction on the uneven bank. Besides, there’s the action of the connecting rods, their weights, their lengths and where they’re connected to the piston. Then, you might consider combustion forces, and piston domes being assaulted by wedging forces—to say nothing of the degree of tumult in the crankcase. I think you’re splitting hairs,” he argued convincingly. “Fine piston balance is neither here nor there.” But from a piston maker’s approach, there are two types of balancing. First, the conventional balance is used to reduce the prospect of significant piston weight variation in large-bore engines. The objective is to maintain bearing loads within the design range, that is, main bearing loads, as they are the focus of engine crank balancing and also of vibration levels. In addition, crank pin and piston pin loads must also be held within their respective design loads. So, in truth, these efforts are more focused on durability than performance. This is why some engine builders see little value in it. However, certain engines will be more sensitive to piston weight variation than others, so it can be important for engines where bearing capacity or vibration levels are reaching their upper limits. The second type of piston balancing is embraced by those engineers ardently seeking any slight advantage and involves manipulating the mass distribution of...

It’s been a busy year for TorqStorm, their 2017 inquiries for superchargers had tripled from the previous year. Established in 2009 in Grand Rapids, Michigan, TorqStorm’s centrifugal supercharger had the advantage of being the product of two accomplished tool and die makers, Chris Brooker and Scott Oshinski, the company’s co-owners and operators. Most notably among the firm’s recent announcements is a new supercharger kit for Chrysler’s Slant Six. Produced from 1959 to 2000, sources familiar with Slant Six engine production believe thirteen million of these power units were produced worldwide. A prototype of the Slant Six supercharger kit was publicly revealed last August at the Mopar Nationals held at Columbus, Ohio. Now available, here are details of the new production unit. When TorqStorm’s supercharger exerts itself, expect a boost range that extends from 1,800 to 6,500rpm, thanks to the design of the compressor wheel. Yet, to the majority of Slant Six owners, slightly less gusto—5,000 to 5,500rpm—is probably all that’s required. But in horsepower increases they seek an additional 100 to 150hp, which is around an 85 percent gain over the stock engine’s power output, and easily within the scope of this new supercharger kit. The kit comes with a robust billet aluminum gear box housing and cover. Within the casing, straight-cut tool steel gears are lubricated by an independent oiling system, and a stout three-quarter-inch thick mounting bracket secures the gear box and compressor assembly to the engine. TorqStorm’s newly designed blow-through carburetor hat is also included as well as an automatic belt tensioner, an 8in diameter crankshaft pulley, a 52mm vacuum-controlled blow-off valve, and related...
