Is It Bad To Hit The Rev Limiter?

What happens if you hit the rev limiter?

A hard limiter cuts either the spark or more commonly the fuel, halting combustion and robbing the engine of all its power in an instant.

That’s what creates such a fierce effect when you hit one.

Power is restored as the engine speed drops by a small amount, then gets cut again as it reaches the limiter..

Why do bike engines rev so high?

Bikes have small combustion chambers because of their small capacity, and they have “oversquare” cylinders, i.e. the diameter of the bore is greater than the stroke of the piston. Both of those reduce the piston speed at a given rpm, or to put it another way, at a given piston speed, the engine will rev much higher.

Is it bad for your car to hit the rev limiter?

If you’re not accelerating, you’re spinning, which is wasted power. Same thing with the rev limiter. If you’re hitting it, your engine is not making as much power as it could to turn the back tire.

So if you rev up the engine in neutral, and shift the transmission into gear, you might just sit there in neutral until the RPMs come down enough for the transmission to engage.

Is 4000 revs too much?

One hour at 4000 RPM twice as much movement as one hour at 2000 RPM. … Max RPM is the limit that the engine can take before severe damage. Running at or near max RPM for extended periods will drastically reduce engine life. Engines are usually more efficient at lower RPM as well.

What does removing the rev limiter do?

Rev Limiter. The rev limiter on a car is there to prevent over-reving, which will destroy the engine. … Some sports cars have it set slightly higher to allow the engine to make more power in the high RPMs. Simply removing the rev limiter, without making any other modifications to a car, will do next to nothing.
