Do 4 cylinders rev higher?

Four cylinder engines seem to you to operate at general higher rpm’s because they are generally small displacement engines that have small pistons with low inertial mass. … But eight cylinders can be designed to run at higher rpms. For example the V8 engine in the Ferrari 458 has a maximum rpm of 9,000.

How do smaller engines produce more power?

By revving harder and therefore working harder, smaller engines can match bigger engines for power. A two-litre four, for example, will produce the same power as a four-litre V8 when it’s revving twice as hard as the bigger engine, provided it’s equally efficient.

Is it bad to rev engine high?

What is considered high rpm?

For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.

Why do rotary engines rev so high?

Rotary engines are also known for revving high, and that’s because in eschewing pistons altogether, they don’t have any reciprocating mass, just rotational mass. You also need lots of air, which is why the Honda S2000 employs variable lift on its intake valves.

Why is a high revving engine good?

The main reason why you may want a high revving engine is simple. Higher revs equals more power, which is particularly nice to have, especially in a sports car. A simple way to go about creating a high revving engine is making sure the bore is larger than the stroke.

What is a dangerous rpm?

If you drive at 5,000 RPM, that bearing is going to use up its lifetime twice as fast as if you were driving at 2,500 RPM. On the other hand, “lugging” an engine at too low an RPM can be harmful, as well. If your prime directive is mechanical lifetime, shoot for lower RPM within a reasonable range (i.e. not lugging).

What should rpms be at 80 mph?

Anything close to 2400 rpm at 80 mph in 6th gear would be great.

What should my rpm be at idle?

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. Two-cylinder motorcycle engines are often set around 1000 rpm.
