what kind of engines are in nascar cars
Monster Energy NASCAR Cup Series The cars are powered by EFI V8 engines with compacted graphite iron blocks and pushrod valvetrains actuating two-valves per cylinder, and are limited to 358 cubic inches' (about 5.8 liters) displacement. However, modern technology has allowed power outputs near 900 horsepower (670 kW) in unrestricted form while retaining the conventional basic engine design. In fact, before NASCAR instituted the gear rule, Cup engines were capable of operating more than 10,000 rpm.[31] A NASCAR Cup Series engine with the maximum bore of 4.185 inches (106.3 millimeters) and stroke of 3.25 inches (82.55 millimeters) at 9,000 rpm has a mean piston speed of 80.44 fps (24.75 m/s). Contemporary Cup engines run 9,800 rpm, 87.59 fps (26.95 m/s), at the road course events on Pocono Pennsylvania's long front stretch and at the .526-mile short-track Martinsville Speedway. At the backbone 1.5- to 2.0-mile tri-oval tracks of NASCAR, the engines produce over 850 hp running 92–9400 rpm for 500 miles, 600 mi for the Coca-Cola 600 Charlotte race.
Ford F-Series For 2010, Ford introduced its second high-performance truck, the SVT Raptor. In sharp contrast to the SVT Lightning, the Raptor is based on Ford's 1000 baja truck, with modifications designed to improve its on-road performance while still including standard Fox suspension, and the most capable off-road, mass-produced vehicle available. For the 2010 model year, the base engine was a 5.4 Liter V8 producing 310 hp (230 kW), the 6.2 Liter V8 was an option added mid year. Between 2011 and 2014, a 411 hp (306 kW), 6.2 Liter V8, both were paired with a six-speed automatic was available. The Raptor features a model-exclusive suspension with long-travel springs and shocks. To make room for its larger tires, the Raptor shares only the cab with a standard F-150; the pickup bed, hood and front fenders are wider and exclusive to the model. Initially available only as a SuperCab, a SuperCrew cab was added in late 2010.
