Sprint Cars are powered by a naturally-aspirated, methanol-injected overhead valve V-8 engines; with a displacement of 410 cubic inches (6.7L) and capable of engine speeds approaching 9000 rpm. [3] A lower-budget and very popular class of sprint cars uses 360-cubic-inch (5.9L) engines that produce approximately 700 horsepower (520 kW). [4] [5 ...
A WoO Sprint Car must weigh at least 1,425 pounds (646kg) with the driver in the car. [9] The mandated 410-cubic inch engine (6.7 litre) produces over 900 horsepower, uses mechanical fuel injection and must run on methanol fuel.
Until the early 2000s, sprint cars in Australia were restricted to 6200 cc (372 cui) V8 engines as opposed to the 410 cui (6.7 L) engines used in the United States and New Zealand. Brian Healey, the Sacramento-based Australian who owned Parramatta City Raceway, pushed for the change in 2003 to follow both nations to 410.
Sprint cars weight 1,475 pounds and have 410 cu in engines that produce 900 horsepower. A typical Midget weighs about 1,000 pounds and produces up to 350 horsepower from its four-cylinder engine. [3] They are intended to be driven for races of relatively short distances, usually 2.5 to 25 miles (4 to 40 km).
The MEL 410 cu in (6.7 L; 6,720 cc) engine was the only engine offered in the 1958 Edsel Citation and Corsair models. It was rated at 345 hp (257 kW) and 475 lb⋅ft (644 N⋅m). Bore and stroke were 4.20 and 3.70 inches (106.7 and 94.0 mm) respectively.
