The best blend of overall performance and economy, VP’s X16 was developed for naturally aspirated engines and is an economically priced choice for two and four-stroke engines with compression ratios of up to 16:1 and for engines employing nitrous up to 300 HP. X16 provides the energy and protection of top 116 octane racing fuels for a decrease value and is an excellent fuel for a wide array of motorsports applications. As the decade came to a close endurance racing vehicles had lost their close connection to road-going sports vehicles with most main races being contested by dedicating racing vehicles. There is probably equal number of teams operating synthetic racing motor oil as these who run regular racing oil. The occasion will be hosted by the Don Garlits Museum of Drag Racing and sponsored for the 16th year by Mopar® Overall performance Parts. My husband also drag races, he has a rear engine dragster, does about 8.30 seconds in the quarter mile.
By the late 1960s the SCCA’s Trans-Am road racing series had morphed into a monster, and Chevrolet’s new Camaro was gearing-up to offer pony auto competitors a swift backhand… to the face… with a torque wrench. Cylinder head porting demands to be accustomed to the usage that the engine will operate at. A head modified for drag racing operating among 7,000 and ten,000rpm will be useless to a rally engine needing far more midrange torque and operating among 3500 and 7500rpm. In the course of racing events the automobiles are classified according to various criteria like configuration of cylinders, engine capacity, frame variety, construction supplies, horsepower to weight ratio, wheelbase, cylinders, or even model and make for the restricted entry fields.
For example, the intersection of the wing and the fuselage at the wing root has considerable interference drag. The ECU tune is a low cost and easy mod, and dyno charts show that this upgrade provides huge horsepower and torque gains all via the rev band. Of course, the obvious way to gain horsepower cheaply is to minimize the weight of your auto. Capable of withstanding lengthy intervals of intense heat, it operates especially properly with alcohol and methanol and is very common in sprint automobiles, late models and World of Outlaws racing. After the racing was over we went back to town, had a barbecue and shake and headed back to Memphis about 1 AM. Road races were run on the higher banked speedway and infield road course, The drag races have been held on the speedway backstretch.
Special attributes of Roush Drag Pack Mustang consist of new place of battery to produce better weight distribution, smaller sized ROUSHcharger pulley and engine calibration, new tachometer with shift light, and the inclusion of an external on/off switch. The trend soon shifted to little-block engines to take benefit of a tangled pounds-per-cubic-inch guidelines recipe that incorporated weight breaks—reportedly typically influenced by inside politics—for longer wheelbase automobiles like a 4-door Ford Maverick.
Teams ran the Chevy 427 Mk IV, Ford Boss 429 or 427 SOHC and the Chrysler 426 Hemi in lightweight ponycars and even compacts like the Chevy Vega and Ford Pinto. The racing fuels may possibly not be utilized for recreational offroading or other non-competitors makes use of. Used in large (500 CI or higher) normally aspirated engines with ultra high CRs of 14:1 or greater. As you can see from our summary above, the planet of drag racing is wide open – someplace out there is a location for you. Other go-rapidly components include Eibach Drag Launch springs, Koni struts and shocks, four-wheel discs from Stainless, Weld Alumastar wheels and Mickey Thompson tires. My Dad was a enormous fan of the Ford 427, which he considered the ultimate engine.
