WASHINGTON: Alarm bells rang in the auto enthusiast community recently after a trade group [SEMA] warned that the EPA was threatening to ban the type of modified street cars that generations of amateur racers have taken to the track. “Relax,” said the EPA, “There’s no new ban being proposed. Fact is such modifications have always been banned under the Clean Air Act.” So what is going on? In our article of last month entitled “EPA threatens to ruin motorsports” we reported that SEMA delegates visited with EPA enforcement officers in Washington DC seeking clarification on the alleged banning of modified street cars. Read Automotive News’ report below: By Ryan Beene, Automotive News, February 15, 2016 Call it a muddled exchange that nonetheless sheds light on one of the EPA’s enforcement priorities in the wake of Volkswagen’s diesel transgressions. In short, the EPA’s concern is not about the emissions of race cars but about keeping all road-going cars free of modifications that would neuter their emissions controls. Adam Kushner, a partner at the law firm Hogan Lovells and former enforcement official at the EPA, says it should be no surprise these days that regulators are scrutinizing how emissions-control systems are being modified in the new-vehicle and aftermarket sectors. “The regulated community is going to need to be watchful,” said Kushner, who was director of the EPA’s Air Enforcement Division from late 2003 to late 2008 and director of its Office of Civil Enforcement from late 2008 to late 2011. The EPA proposal that sparked the recent controversy seeks to add language to a “prohibited acts” section of existing light-vehicle regulations saying...

Since we’re always looking for smart ways to gain more horsepower, one of the best approaches is supercharging. It’s a device designed to grab Mother Nature by the scruff of the neck and shake her silly. Supercharging dramatically ups the ante on the pressure and quantity on your intake charge thereby making significantly more power for an internal combustion engine. Call it “unnatural aspiration”. The concept has been around for 131 years and even helped generate the power for some of history’s greatest prop-driven fighter planes.

By Fergus Ogilvy: Right at the end of the last century, probably the autumn of 1999, senior R&D man at Renault F1, Dave Hamer, was asked to investigate what could be done to stabilize their wind tunnel model. At that time it was a half-scale model (50 percent) of their current Formula One car and it had a tendency to yaw (move laterally) during wind tunnel testing. Previous attempts at reinforcing the supporting strut had failed; to their dismay it merely increased its natural frequency of oscillation. “The supporting strut is very under-damped,” explains Hamer, “therefore it was easily triggered into oscillation.” Could a mass damper stabilize the model in the wind tunnel? To oppose and kill the oscillating forces, he suggested the use of a tuneable mass damper, similar in concept of those placed at the top of some skyscrapers to protect them from the effects of earthquakes. The Taipei 101 skyscraper uses a tuned mass damper that weighs 800 tons. “We hired a specialist company to conduct a stability analysis of the model,” said Hamer, “and our drawing office designed some devices. But they didn’t work very well. Confined space within the model was the chief impediment.” Then four and a half years later, in 2004, another attempt was made. By now the wind tunnel and the work performed within it was more refined. Most significantly, the R&D department had access to a vibration specialist, who was on loan from Renault at the time, and between him and the then Head of the race team’s R&D department they introduced a leaf spring to address the instability of...

Written by Moore Good Ink Using the most powerful processors in the industry, Big Stuff 3 EFI controllers dominate Pro Mod, Outlaw 10.5, NHRA Comp Eliminator, Bonneville competition—and now it’s the impelling force in hundreds of street-strip engines. In 1983 John Meaney, originating from the south side of Chicago and now in his early twenties, had an idea for a carburetor. But his Professor at Valparaiso University said, “Don’t waste your time on those things they’ll be extinct in five years. Why don’t you consider an electronic fuel injection system?” Persuaded by its novelty and its potential, he, aided by his professor, made an EFI system, adapting it for use on his 1969 Camaro. On the last day of school he gave some of the engineering profs rides in the parking lot. “They were all smiles,” exclaimed John, “They thought it the best.” After college John took employment at UTC (United Technologies Corporation) in Michigan. UTC owned aerospace manufacturer Pratt & Whitney and worked closely with GM, who was embarking on an ambitious program to create a replacement Bosch injector. “But when I realized the program wouldn’t get off the ground, I went to work for Bosch at their Farmington Hills location in Michigan.” Bosch years At Bosch, a Germany company based in Stuttgart, luck intervened on John Meaney’s side. Not only was he responsible for developing the full engine management program but also he discovered his supervisor was an ardent racer with a 1969 Camaro. Normally an engineer would be assigned to a single project, like developing a fuel injector or a fuel pressure regulator or an O2...

Written by Moore Good Ink: Why precipitate the loss of a perfectly good clutch when it can be avoided? Ram Clutches offers two valuable tips: On chassis dynamometers Probably the greatest threat to the longevity of a clutch system is imposed by the chassis dynamometer. Because there is no tire slippage during the run, any hint of engine lugging can cause the clutch to slip. Consequently chassis dyno time is much more strenuous and abusive on your clutch system than racing passes at the drag strip. At the drag strip On the burnout make certain the tires are wet but not operating in the water. As they begin to gain traction with the pavement, depress the clutch pedal. Do not attempt to extend the burnout toward the tree. When the tires hook they exact a heavy load on the clutch, especially in 3rd or 4th gears. To extend the burnout further exposes the clutch system to a tremendous and unnecessary load. Though this may sound elementary, make certain your car is in first gear before you leave the starting line. Leaving the line in 3rd gear will almost certainly destroy your clutch system. So, prior to pre-staging always ensure you select 1st gear. Lastly, ‘hot lapping’ can transmit severe heat to the clutch. Though some events require consecutive runs always try to provide sufficient time for the clutch to cool. Focus on making quality runs rather than quantity.
