The engine in today's NASCAR racecars produce upward of 750 horsepower, and they do it without turbochargers, superchargers or particularly exotic components. small block 5.7
The NASCAR engines have extremely radical cam profiles, which open the intake valves much earlier and keep them open longer than street cars. This allows more air to be packed into the cylinders, especially at high speeds (see How Camshafts Work for more details).
The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either.
They have carburetors that can let in huge volumes of air and fuel -- no fuel injectors on these engines.
They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power.
All of the subsystems like coolant pumps, oil pumps, steering pumps and alternators are designed to run at sustained high speeds and temperatures
ON e nebunie masina asta da mai mult e SHOWCAR ramane de apreciat proiectul si munca depusa..motorul poate sa fie de TOYOTA FORD DODGE CHEVROLET
