How two valves working in tandem prevent crisis

How two valves working in tandem prevent crisis

Nitrous Supply’s latest developments. By Alfie Bilk: The long 5/8in OD supply tube extends down into the nitrous oxide cylinder, its flared end reaching within 5/8in of the cylinder floor. Like a velocity stack the 45-degree flare is formed because fluids or air don’t react well to deviating more than 15 degrees says Nitrous Supply’s Mike Flynn. “If we left it squared-off, the flow in the tube would be adversely affected”. Their valve, he claims, has the highest flow of any valve you can put in a nitrous bottle, so forming the bell mouth at its entry helps smooth the flow and uses the full capacity of the tube. The supply tube is connected to the bottle valve which, in turn, is connected to the nitrous oxide bottle or cylinder via a number 8 fitting. The seal between the two components is aided by a white Teflon® O-ring. On one side of the bottle valve a pressure relief device is positioned. Sometimes known as the racers’ safety valve, it is an emergency mechanism that vents dangerously high-pressure gases into a tube through its nozzle end. Set to deploy should the cylinder pressure escalate to 2700psi, the vent tube, which is connected to the safety device by a -8AN fitting, is routed outside the vehicle. Recently, the nozzle of the safety device has evolved and now features four 3/32in holes rather than one large hole. The four holes act as an effective diffuser should pressure build and activate the emergency relief mechanism. In dire circumstances, one hole can be potentially dangerous suggests, Mike Flynn. What would cause the pressure relief device...
EPA threatens ruin to motor sports

EPA threatens ruin to motor sports

About twenty days have passed since three SEMA delegates paid a visit with two senior EPA enforcement officers in Washington DC.  SEMA had uncovered a few sentences buried in a 630-page document and was seeking clarification. The document related mostly to the emissions of heavy-duty on-road diesel vehicles but also included further proposals that would have extraordinary ramifications to our aftermarket industry. The EPA’s current interpretation of the Clean Air Act is thus: any vehicle that conformed to emission compliance when constructed but is now out of compliance is in violation. The SEMA representatives asserted their disagreement and informed them that their opposition would be robust. Four days later a conference call was made to several heads of state. The callers included approximately twenty associates from our industry, including those representing SEMA, NASCAR, NHRA, IMSA, and original equipment manufacturers. Currently, SEMA is seeking legislative relief and considering judicial relief in the courts if necessary. When they released their petition earlier this week, SEMA’s goal was to obtain 100,000 signatures. By Wednesday evening, numbers had exceeded 119,000. In the hope of ending these destructive policies, please go to the Click here! request below and add your signature.     SEMA has issued a press release informing the public that the U.S. Environmental Protection Agency (EPA) is aiming to make it illegal to convert automobiles originally designed for on-road use into racecars, even though such conversions have been made for decades.  Under the EPA’s proposed rule, it would also be illegal to sell any performance-related products for those cars.  The EPA’s proposal would have a devastating impact on motorsports since many types of...
How hospitality wins the day: Stroke of marketing genius

How hospitality wins the day: Stroke of marketing genius

By Vic Moore: There are many things for which the 2016 MPMC conference will be remembered: the fact that I didn’t have my accommodation at the host hotel booked on time, which caused me to encamp around the back at the Best Western—saving $200! Or the fact that my visitation card had pegged its limit at 42 meetings over the three-day conference—a convention held each January in Orange County, California by the Motorsports Parts Manufacturers Council, where 100 of our finest innovative companies meet the media. But no; for hospitality one meeting overwhelmed all others. Who could forget the welcome as Autometer’s irrepressible Joseph Mills allowed us to settle in then proffered a glass of Jack Daniels? Furthermore, the grateful recipients automatically became the fortunate winners of a prize. Momentarily, mine was a battery charger until an opportunist, mentioning no names—MONGOOSE McEWEN— deftly reached forward and snatched the spoils, saying his need was more profound than mine! But who could argue with hospitality that energizes the relationship, rejuvenates the day and, no doubt, assisted several imbibers through their afternoons!   Tach season is upon us – generous discounts always leaves favorable impression with racers There are few things more recognizable in the performance world than an AutoMeter tach.
