Is Revving a Car Bad?

Whether or not revving is bad for a car depends on a few factors.

Some car engines are designed to be revved. No matter how much revved you do to these engines, no damage will happen.

On the other hand, some engines don’t love rev at all. They love to work at low RPM, which is considered safe and secure. If you force these engines to reach a high RPM level, you risk engine damage. Frequent revving will permanently damage these engines, and you must say “goodbye” to it.

Now one question might have popped up in your mind, is there any rev limit?

The straightforward answer is YES. For average engines like V8 engines, the rev limit is 6,500 RPM. Going beyond this rev limit will damage your car engine severely.

Meanwhile, engines like BMW or Honda engines love revving, and the limit is 8,000 RPM. You must not surpass this ROM level. Otherwise, you are increasing the chance of engine damage.

In the end, frequent or non-stop revving should completely be prohibited. How much power your engine is or how much HP it makes, constant revving will damage your engine for sure.

What Happens When You Rev a Car Too Much?

As I already stated, too much revving will definitely damage your car engine. Let’s see what damage can happen you’re your engine.

Engine Block Damage

When you rev too much, possible scarring will appear in the cylinder walls. Heat-related complications will also arise, which could crack or damage the block. We suggest you not rev your car engine when it is cold.

Failure of Engine

Your car engine may fail dramatically when you rev it suddenly. There must be oil between the crankshaft and the bearing. During a sudden rev up, the bearing may spin without proper oil presence and cause engine failure. Don’t take a chance to rev your car engine in the cold because engine failure is an expensive fix.

Turbo Damage

Rev can damage your turbocharger turbine as well. Without oil, the turbo will not perform efficiently. The oil is thick during engine starts, and it takes time to thin and lubricate the turbo. If the rev happens suddenly, it might be bad for your turbo and cause it to fail.

Last Words

You must not rev the engine if it is not built to be revved, as such work will damage your car’s engine and related parts. At the same time. Avoid revving cars in cold or snowy conditions. I suggest you rev the engine when it is hot. Otherwise, you will end up with many engine-related complications, which can ruin your day and cost you a lot of bucks.
