Gasoline automobile engines typically will have a redline at around 5500 to 7000 rpm. The Gordon Murray Automotive T. 50 has the highest redline of a piston-engine road car rated at 12,100 rpm. The Renesis in the Mazda RX-8 has the highest redline of a production rotary-engine road car rated at 9000 rpm.

Does high rpm hurt engine?
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
What RPM is too high?
Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it’s sufficiently warmed up, you might have a problem. High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well.
Why do Japanese engines rev so high?
The answer is typically for power purposes. As torque remains fairly consistent across a given powerband, horsepower will rise as the revs do. So when an engine can rev higher then it will also make more power. … That’s why an AP1 Honda S2000 revs a bit higher than the later AP2 Honda S2000.
How fast is 7000 RPM in mph?
7000 rpm would be about 91.7 mph.
Why can F1 cars rev so high?
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. … Formula 1 engines and motorcycle engines often have very high bore/stroke ratios, allowing for higher engine speeds (and thus more power).
Why do F1 engines idle so high?
A race engine revs higher so doing so would be far from the optimal in terms of the weight of the parts involved, so we do the opposite: throw the modes as low as possible using rather soft shafts. But then you should not run the engine on these modes so you raise the idle to be above them.
What is a safe RPM range?
For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.
What should your RPMs be at 80 mph?
You should be at around 3300-3400 rpm at that speed.
How many RPM is normal?
For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm.
Does high RPM clean engine?
Yes, higher engine speed is a part of knocking off the build-up but high air flow and high heat loads assist in the cleaning process as well.
Is going 6000 RPM bad?
No rpm is bad for an engine as long as it’s under the redline. It’s as simple as that. So if the redline is at or above 6000rpm, you can happily run it at 6000 rpm if you’d like. Stomping on the gas at low rpm for extended periods, that’s what gets you a worn engine.
Is it bad to go over 3000 RPM?
Running an engine some 3000 RPM below its redline should be absolutely find for extended periods of time. It might “sound” a bit revvy if you run the engine at that RPM when stationary – and indeed it might get hot quite quickly as it will not have the cooling airflow that occurs when driving.
