Why do turbo cars not rev as high?
It is simply much more expensive to make high reving Turbo petrols. Need much better balanced rotating components, lighter & stronger internals. NA engines may rev to much higher rpms but they aren’t making much torque at those RPMs, high horsepower is simply coming from more revs( hence more bangs per minute).
Can turbo engines rev high?
So, yes it’s not impossible to have a high rpm turbo engine. -High rpm means higher piston speeds which again means going the oversquare route (stroke is smaller than bore) like McLaren’s engine is. Fully doable and not that big trade offs.
Why do turbos rev lower?
So the bottom line is: turbocharged are slower because they don’t need to be faster.
Why can’t engines rev higher?
Generally, the limiting component of regular cars’ ability to rev higher is the valvetrain. Moving components in the engine have inertia. This means that when they are moving, they want to keep moving. As the engine speed increases, the speed of the components increases inside of the engine.
Why do turbo cars have lower redline?
To make more power in an NA engine of limited/fixed displacement, you need to suck in air more often, which means higher revs. Therefore, high-end modifications to NA engines are focused on allowing the engine to rev faster without breaking anything.
Does a turbo lower rpms?
Turbocharged engines make big torque at low rpm, but those two numbers, peak torque and its corresponding rpm, don’t tell the full story, as boost pressure isn’t solely a function of engine speed.
What is the highest revving V6?

How do Formula One engines rev so high?
Formula 1 Cars Rev So High To Achieve Maximum Power
Combustion occurs at the top of each cylinder; the pistons are forced down, turning the crankshaft. The crankshaft turns the main shaft in the gearbox, and the energy is driven down the driveshaft to the wheels.
At what RPM do turbos kick in?
The turbine in the turbocharger spins at speeds of up to 150,000 revolutions per minute, which is 30 times faster than most car engines can go.
At what RPM is Turbo activated?
The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) — that’s about 30 times faster than most car engines can go.
How do you stop turbo lag?

- 5: Sequential Turbocharging.
How do I make my engine rev higher?
One of the simplest ways of creating a high revving engine is to start with an oversquare design (larger bore than stroke). There are multiple advantages of this type of design, but as far as engine RPM is concerned it keeps the piston speed relatively low.
Why is 7000 RPM the limit?
Petrol engines usually redline at 7000-8000 RPM while diesel hits the peak at around 4500 RPM. This is because diesel engines are not made for high RPM in the first place. They are slow to combust than petrol and are mainly focused on more torque rather than RPM.
