who owns the number 3 car in nascar
Dale Earnhardt A common misconception is that Richard Childress Racing "owns the rights" to the No. 3 in NASCAR competition (fueled by the fact that Kevin Harvick's car has a little No. 3 as an homage to Earnhardt and the usage of the No. 3 on the Camping World Series truck of Ty Dillon), but in fact no team owns the rights to this or any other number. However, according to established NASCAR procedures, RCR would have priority over other teams if and when the time came to reuse the number. RCR owns the stylized No. 3 logos used during Earnhardt's lifetime; however these rights may not prevent a future racing team from using a different No. 3 design (also, a new No. 3 team would most likely, in any case, need to create logos which fit with their sponsor's logos).
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.
