Just remember never to do this while the engine is still cold!

What happens if you rev your engine too much?

If an engine goes overspeed, commonly called “over-revving”, damage to the piston and valvetrain may occur when a valve stays open longer than usual. Valve float can possibly result in loss of compression, misfire, or a valve and piston colliding with each other.

Is it safe to rev engine in neutral?

Yes, this causes engine wear. When the transmission is in neutral and the engine is “revved” without any load, the spinning engine internals will accelerate, gathering rotational and lateral forces at a faster rate than designed by the manufacturer. Rapidly revving an engine will heat up the piston rings much faster.

Does high rpm hurt engine?

High RPM get much worse nearing max 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.
