What allows an engine to rev higher?

Lower piston speeds means less stress on the connecting rods and crankshaft as well as acceptable flame propagation speeds, allowing the engine to rev even higher. Also, by having a wider bore, you can have larger intake and exhaust valves, leading to better airflow at high RPM.

Do cars not have rev limiters?

Most [modern] cars, if not all of them, have rev limiters, regardless of the transmission type. Most, if not all, if your car is fuel injected. Older cars do not have this limiter in most cases.

Do all cars have a rev limiter?

Yes, pretty much every car has a rev limiter, and modern ones are always controlled by the ECU. Rev limiters are usually done one of two ways – by cutting the amount of fuel injected (fuel cut) or by not firing the spark plugs (spark cut).

Is it safe to remove rev limiter?

If you remove the rev limiter without much expertise, you run the risk of damage to the gearbox, engine or other components. In addition, the change ensures that the wheels and tires are exposed to a greater load.

Does revving damage engine?

When you rev your engine, you place additional and unnecessary stress on your car and its engine. This is imperative when it’s cold outside—revving your engine before it has had time to warm up is especially damaging, as the engine’s oil hasn’t had sufficient time to circulate and properly lubricate your car.

Does driving high revs damage engine?

Your engine is most at risk from damage when cold, so putting undue stress on it by high revving will exponentially increase the damage done. The combustion process does not become efficient until the engine reaches its operating temperature. An inefficient burn leaves acids and other toxins that eat your engine.

Is it OK to hit the rev limiter?

The rev limiter does not hurt your engine, but bouncing the car off the rev limiter continuously is not a good idea either. If you hit the rev limiter before you shift it slows your run and wastes fuel.
