So that gives you an idea of how much aluminum is sitting on the floor when we are done.. The foundation of the NASCAR-Approved Spec Engine is a production GM LS2 block (6.0L / 4.000) with LS2 CNC ported heads. These performance enhancements that ECR creates is all part of the teams engine development philosophy, which is not to develop the engine as an 8-cylinder engine, but rather as eight one-cylinder engines. The next regs are to be introduced for a six-year period, 2021-2026 inclusive, and on-track testing will commence in the summer of 2020. [24] The injection system used by NASCAR is a different system from that used in IndyCar Racing and other motorsports series; the EFI system that NASCAR put into use was compatible with the old restrictor plates, allowing NASCAR to continue to use them to keep the speeds lower at the superspeedways and save costs for race teams. [28] A NASCAR Cup Series engine with the maximum bore of 4.185 inches (106 millimeters) and stroke of 3.25 inches (83 millimeters) at 9,000rpm has a mean piston speed of 80.44 fps (24.75m/s).

We can customize the engine for each racetrack for each week based on the particular engine speed characteristics and throttle characteristics of the track and even the driver who is going to be driving it, to make sure that the power curve is optimized to produce minimum lap time at that specific event.. "Our drivers have been asking for more horsepower and thanks .
