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 ...
Sprint cars are open-wheel race cars, designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Historically known simply as "big cars," distinguishing them from "midget cars," sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa.
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.
However, certain engine sizes were common, and could be considered the "standard" Offenhauser engines: [7] 97 cu in (1.59 L) - to meet the displacement rule in many midget series; 220 cu in (3.6 L) - displacement rule in AAA (later USAC) sprint cars; 270 cu in (4.4 L) - displacement rule for the Indianapolis 500 under AAA rules [11]
The Dolomite Sprint has been described as "the world's first mass-produced multi-valve car". [12] Multi-valve engines had first appeared in 1912, with the most recent prior to the release of the Sprint engine being the Cosworth BDA (1969) and Lotus 907 (1972), but they had not been not used in mass-production vehicles until after the ...
Like sprint cars, supermodifieds do not have starters, batteries, or transmissions, and are push-started. The combination of high power, light weight, and high cornering ability allows supermodifieds to average over 120 mph (190 km/h) on a 1/2-mile oval and 150 mph (240 km/h) on a 1-mile (1.6 km) oval, with top speeds over 190 mph (310 km/h).
This engine was used in the 1966-67 Tempest and Le Mans and 1967 Firebird. An optional high-performance Sprint version featured high-compression pistons, hotter cam, dual valve springs, split/dual exhaust manifold, stronger coil, and the then new Rochester Quadrajet carburetor. rated at 207 hp (154 kW).

The 1.3-liter inline-four engine offered 70 hp (52 kW), and was the same engine that had been in use in the Suzuki Swift (except for the GT models) in prior years. LSi models produced after 1997 featured the four-cylinder engine with a sixteen-valve head instead of the eight valves of the earlier design, yet was still a SOHC design.
