MADCAP Racing Engines, owned/operated by Bob Reinhardt, posted this video to Facebook yesterday of them testing a 500 cubic inch NHRA Pro Stock engine to 10,500 rpm on their dyno. The engine is revved up to the minimal rpm the engine would see during a 1/4-mile run (~8,500 rpm), then loaded by the dyno, and swept through the narrow, high rpm range to the NHRA mandated peak rpm of 10,500 rpm. Power numbers kept confidential (for obvious reasons) but typical for these engines is ~3 hp/ci.
For the "thin" oil fans here, this engine uses a 0w-8 oil from High Performance Lubricants.
Crank the volume up, and enjoy the beautiful sound of a 500ci V8 screaming at 10,500 rpm.
