Why do race engines rev so high?
The pistons in F1 engines are different to the ones in usual car engines. They have a greater diameter and a lower height, therefore allowing a lot higher RPMs. An engine that has a lighter weight reciprocating mass can spin a higher rpm.
What is the advantage of a high revving engine?
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. A wider bore also leads to improved airflow at high rpm – F1 and motorcycle engines make for the best examples.
Is it bad for your engine to rev 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 VTEC engines rev so high?
revolutions is the only replacement for displacement. Honda engines are usually oversquare, (shorter stroke, larger bore) then other engines of the same capacity, Allowing them to change direction more quickly. Hence they can rev higher.
Is 3000 rpm too high?
3k is not high revs… you car can take more, actually it is good for your car to be pushed higher than that but i would not redline it constantly either. IN my daily commute I usually drive in town or traffic and hardly go above 3000-3500 rpms.
How fast is 7000 rpm?
7000 rpm would be about 91.7 mph.
Is going over 4000 rpm bad?
There’s no harm running your engine at 4000 rpm for five minutes as long as the engine or cvt don’t overheat. Vehicle manufacturers regularly test engines on dynamometers at wide open throttle for hours at a time.
Is it good to redline your car once in awhile?
However, there’s no need to worry. Redlining will not damage an engine or cause it to explode, no matter how cruelly you treat it. Therefore, revving the engine to its maximum speed several times a week is not a problem. Just remember never to do this while the engine is still cold!
Is driving at 5k rpm bad?
You’ll be fine. The reason it’s so sluggish is that the transmission is programmed to save fuel so it’s always in a higher gear. Great for fuel economy, bad for performance. Depending on your speed, it could downshift 3 gears to get the performance you’re looking for.
What should rpm be at 50 mph?
1500 rpms for 50 mph sounds about right. your overdrive works.
What RPM should my car be at 80 mph?
You should be at around 3300-3400 rpm at that speed.
