There's also a 10,500 rpm limit and the IRL is committed to stable rules for several years. The Infiniti Q45 provides a perfect platform for the race engine and this will be Infiniti's introduction to motor sport. The engine installation is a fully-stressed installation. The engine is all-aluminum and fully skirted. The main bearing studs are continued through the bottom of the pan for stability.
Significant parts are from the production car.
We expect 650 horsepower, well now that's a real number, 2.6 hp per cubic inch. This is a high technology engine. The speed of the engine is 207mph. At 10,500 rpm, the intake and exhaust valves each open 87 times per second. One of the other important features of how everything's coming together in the IRL is the unusual cooperation between Nissan, GM, Dallara and G-Force.
