Parts for average street cars are not interchangeable with racing parts in Hesperia, CA intended for high-performance engines. Not only will they not be able to withstand the pressures placed on them when you rev to high RPMs and triple-digit speeds on the track, but they are unlikely to fit in your engine anyway. Here are seven differences between street and racing cars that show why you want the right parts:
- Engine size: On a street legal car, 358 cubic inches and 5.87 liters is considered a large engine. Engines on racecars are much larger and meant to exceed the 300 horsepower often considered “high-performance” with cars you buy in the showroom.
- Exhaust systems: You are required by law to have a muffler and catalytic converter on your daily commuter. This is especially true with California’s emission control laws, which place further restrictions on your exhaust system. Race engines do not include mufflers or catalytic converters, and the exhaust system is tuned to provide additional boost. This is to assure an advantage in competition, and it is not considered acceptable with consumer grade vehicles.
- Ignition timing: There are few parts on a racecar that are not made to maximize speed, and that includes ignition. The system is programmed so customized spark timing provides the most power at different points of acceleration.
- Pump systems: If you took your regular vehicle and raced it like a NASCAR performer, you would first discover multiple systems overheating—likely all at once. That is because the pumps in your engine would not keep up with that performance. In racecars, coolant, steering, oil and alternator pumps are designed to withstand this high demand so you can keep in a race and avoid a trackside breakdown.
- Precision: Machining for racing parts in Hesperia, CA is a precision art. Cylinders, crankshafts and other rotating parts are designed with specific tolerances in mind. Making these parts too big or too small increases friction that can compromise power and performance. Even being off by one quarter of a millimeter can reduce your racetrack performance.
- Testing sequences: Once assembled, a race engine is put through a series of tests to see how it tolerates the high speed and excessive heat resulting from its performance potential. In each test, it must run for 30 to 120 minutes consecutively so technicians can check for weaknesses and address them. Once the engine passes, it is ready to be installed in a car for racing. Street legal cars are also tested once they leave the assembly line, but not to this extent.
- Intake valves: Part of the cooling process of racecar engines is the intake valves. They remain open longer than on street vehicles, and that gives the cylinders more air and increased power. That process is not necessary for consumer models.
