Is it OK to rev in a manual car?

If done correctly, revving the engine will not negatively affect your engine, drivetrain, or any other car components. Revving a manual is different from revving an automatic car, but they work on the same principle, disengage the gear in some way and press the gas pedal.

Can you rev a car in neutral?

Depending on the year/model, the rev limiter will not allow you to redline in neutral.It will cut off the engine before the rpms can do damage. Usually cuts it off at 4000 rpm – depending on year/make/model.

Do you rev a car in park or neutral?

With the vehicle in park, press the accelerator down slowly, and the RPM needle will climb. You can also rev the engine with the car in neutral, but if you opt for this, be sure your other foot is on the brake; in neutral, the car can roll forward and backward.

Why do modern cars rev hang?

As Road & Track contributor Jason Fenske explains in his latest YouTube video above, rev hang in most modern cars with stick shifts is a result of manufacturers attempting to reduce emissions generated by the engine during gear changes.

Is it safe to redline a car?

Consistently redlining your car can cause serious damage to not only your tires, but also your engine. For those with manual-shift modes or manual transmissions, it can be quite easy to redline (whether on accident or on purpose) and eventually cause your engine to wear down prematurely.

Is it good to rev your engine occasionally?

When you rev your engine, you place additional and unnecessary stress on your car and its engine. This is imperative when it’s cold outside—revving your engine before it has had time to warm up is especially damaging, as the engine’s oil hasn’t had sufficient time to circulate and properly lubricate your car.

How do you rev a manual car in neutral?

With your car in neutral, press on the gas to rev your engine. You should see the needle on the RPM gauge move when you do this. Once the needle on the gauge starts falling again, press the brake so that you can shift back into drive.

Is it OK to rev in park?

No, revving your engine while you’re in park is generally not bad. You can also rev it in neutral without hurting it—just be mindful of how much you’re revving your engine, and for how long.

What is free revving?

free revving – that’s an easy one – it is describes as the engines ability to change speed – revoloutions per second. this depends on a few factors – all of which effect each other.

Is it good to redline your car once in awhile?

After all, when redlined, an engine can sound like it’s about to blow. 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.

How To Rev A Car in 4 Simple Steps

Disclosure: We may get commissions for purchases made through links in this post.

Even if you’re not an automotive expert or mechanically inclined, you’re probably familiar with the concept of revving a car. Maybe you heard someone revving their engine at a stoplight, or perhaps you just got an exhaust system upgrade and want to show off the loud noise by revving the engine. But how exactly do you do it? We’ve done the research so you don’t have to.

To rev your car, do the following:

Turn the car on. Wait 10 to 20 seconds for the engine oil to properly lubricate all of the engine components. With the car in park, press the accelerator. The RPM on the tachometer will increase as the accelerator is pressed. Make sure the RPM doesn’t reach the redline. Release the accelerator, and the engine will return to its idle RPM.

If you have some additional questions about revving a car, hang around. In this guide, we’ll teach you all you need to know about revving a car. Just keep reading for more information!

What Does It Mean To Rev A Car?

So what does revving a car mean, exactly? Simply put, revving means suddenly increasing the engine’s RPM by pressing the accelerator when the car is in park or neutral. People primarily rev engines to show off loud exhaust systems. Drag racers might also rev their engines right before starting a race to accelerate as quickly as possible.

Revving Tutorial

Here we’ll discuss the steps we mentioned earlier in more detail.

1. Turn The Car On

In order to rev a car, the engine must be running. Like we established earlier, revving refers to the sudden increase in engine speed, so the engine must be turned on in order to rev it.

2. Wait For The Oil To Circulate Through The Engine

It’s always a good practice to wait 10-20 seconds after turning the engine on before increasing engine RPM, but this is especially true when it comes to revving the engine. Idling for this length of time allows the oil to circulate through the engine to properly lubricate the engine’s components.

Since the engine RPM will increase substantially when you rev it, the engine can be more easily damaged if it’s not adequately lubricated with oil first.

Watch this video to get a better idea of how engine oil circulates through an engine:

3. Press The Accelerator

Now that you’ve waited 10-20 seconds, the engine oil has made its way through the engine and is providing much-needed lubrication to the engine’s components.

With the vehicle in park, press the accelerator down slowly, and the RPM needle will climb. You can also rev the engine with the car in neutral, but if you opt for this, be sure your other foot is on the brake; in neutral, the car can roll forward and backward.

When revving the engine, be sure to not let the RPM get into the red area on the tachometer (we’ll talk more about the dangers of redlining later).

4. Release The Accelerator

Once you’ve revved the engine to your heart’s content, simply release the accelerator, and the RPM needle will return to its idle position.

Video Tutorial

This video goes over the process of revving the engine of a car:

Is It Bad To Rev Your Car?

At this point, you might be wondering about how revving a car affects the engine. While revving a car might sound really cool, doing so does cause unnecessary wear on the engine, so it’s best to not rev your engine often.

When you rev the engine, the engine speed increases drastically in a short period of time; the engine speed goes from idle (approximately 600-1,000 RPM) to extremely high (5,000+ RPM). In normal driving conditions, many engines virtually never reach such speeds. If they do, the engine speed increases more slowly. Simply put, the drastic increase in engine speed from revving puts more stress on the engine’s components.

Thus, it’s best to avoid revving your engine often. Doing so on occasion likely won’t cause engine damage as long as you only rev it briefly and avoid redlining it.

What Happens When You Redline A Car?

An engine’s redline is the maximum speed at which an engine can operate without causing damage to the engine and its components. In other words, if an engine’s RPM goes past the redline and stays there for a prolonged period, catastrophic failure will undoubtedly follow.

It’s important to point out that redlining the engine doesn’t just pertain to revving the engine while parked. Pushing your engine to the redline while driving is just as harmful to the engine and its components. Always keep an eye on your engine’s RPM to prevent it from reaching this speed.

Can You Rev A Car In Park?

Yes! If you do plan on revving your engine to show off a new exhaust system, the safest way to do so is while the car is in park. As mentioned, if you rev the engine while the car is in neutral, it can roll forward or backward.

How Do You Rev Your Engine While Driving?

If your car has a manual transmission, there are two ways to rev the engine while driving.

Press the clutch in and press the accelerator. Since the clutch is pressed in, the engine is disconnected from the rest of the drivetrain, so you can freely rev the engine without affecting the speed of the vehicle. While driving, press the clutch and shift into neutral. Once in neutral, you can freely rev the engine. This method is simply a more roundabout way to rev the engine in a manual car.

In Closing

Revving the engine can be a fun way to show off your car’s new exhaust. If you want to rev your engine, refrain from doing so frequently, and when you do, make sure the RPM needle doesn’t pass the redline.

We hope this guide has helped you better understand how to rev your engine. Before you go, be sure to check out these other automotive guides:

How To Rev Engine Without Moving In Automatic And Manual Car

Want to rev your car? Can you rev your car without moving? Here’s a simple guide on how to rev an engine without moving in an automatic or manual car.

While the internal combustion engines are still alive, why not seize the opportunity and hear the engine roar.

There are a few reasons you would want to rev up the engine. You may do it to hear the sound of the engine or exhaust, or perhaps you want to get off the line as quickly as possible.

In some cases, revving up the engine could help diagnose or even fix some car problems.

Whatever the case may be, we will guide you on how to rev an engine, regardless if you have an automatic transmission or a manual one.

Here is everything you need to know about making your car go “vroom”!

Table of ContentsShow

Principles Of Revving An Engine

While there are differences when it comes to revving an automatic versus manual, there are some principles that are universal and applied to both types of transmissions.

The first thing to consider is to rev at an appropriate place and time when it is safe to do so. Your neighbors would certainly not appreciate waking up to you revving the engine.

People like to rev differently; some like to rev in short intervals, gradually building up toward the redline (but not reaching it).

Others prefer to rev the engine by pressing down the pedal to the metal, hitting the rev limiter at the redline, which may damage the engine (more about that at the end of the article).

Whatever way you prefer, revving an engine is like directing a symphony. It is possible to be bad at revving, which will be noticeable to other people.

The greatest mistake beginners make is that they press the gas pedal too hard, release it and then press it again at a too-long interval.

Also, please do not rev the engine when it is cold as you risk damaging it.

How To Rev An Automatic Car Without It Moving

There are a few ways to approach if you would like to rev your car and have an automatic transmission.

The best way to rev an automatic car is to put it in neutral (N) and press the gas pedal while simultaneously pressing down the brake pedal.

The latter is not always necessary if you are on a flat surface, but it is still recommended to prevent any movement.

Many times, people are concentrated on looking at the rev counter or have their minds somewhere else, not noticing that the car is slowly moving as it is in neutral.

Therefore, make it a habit to keep the brake pedal down when revving.

It is also possible to rev the car in park (P); the procedure is the same as when the vehicle is in neutral.

Some cars with paddle shifters allow you to momentarily switch to neutral by pressing down both paddles simultaneously, which can come in handy as everything is by your fingertips.

An important thing to keep in mind is to let the engine’s RPM go back to normal idle before putting the car into first gear or driving. If you don’t, you risk damaging the transmission, which is not cheap.

How To Rev A Manual Car Without It Moving

Revving a manual car is easier and more common to do, and the reason lies in the third pedal, the clutch.

The clutch enables you to go in neutral at all times, even when driving 85mph on the highway (not recommended).

If you want to rev while standing still, you can either do so by simply being in any gear, fully pressing the clutch while revving by stepping on the gas pedal with varied pressure.

It is also possible to rev without pressing the clutch by putting the car gearshift in neutral and pressing the gas pedal.

In both scenarios, you may also engage the e-brake to ensure that the car won’t go anywhere.

While it does not cause the same damage as in an automatic, it is preferable not to drop the clutch while in gear before the RPMs go down to idle.

This would be analogous to suddenly putting the car in “D” when the car is revved up.

Advanced Manual Revving

While revving the engine is very straightforward in a manual car, there are some instances where revving the engine is a bit more complicated, namely when rev-matching.

Rev matching is done when downshifting the car at relatively high RPMs to match the new gear’s engine- and transmission speed.

For example, if you are on a racetrack and driving with around 3500 RPMs in fourth gear, slowing down for a corner, you would want to downshift the third gear to still be in an effective powerband.

This would enable you to have a significant amount of power when accelerating again.

By rev-matching, you enable the engine to match the RPMs of the new gear, providing less stress on the driveline and limiting severe weight transfer (inability to steer).

It is done by pressing the clutch pedal, switching to a lower gear, and before releasing the clutch pedal, blip the throttle and normally release the clutch.

This is not only exclusive to racing but can be implemented for everyday driving, even at lower RPMs. It will result in a smoother ride and, if done right, less wear on your transmission and clutch.

How To Not Rev An Engine

Now that you know how to rev both an automatic and manual car, there are a few things that you should avoid when revving an engine.

While you may come across the internet that revving will pressurize the fluids, and make the engine oil circulate faster, which has some truth in it, you should not, at any time, rev a cold engine.

Only rev an engine that has reached normal operating temperature with all the related fluids.

If you do not, you risk damaging internal components of the engine as the oil is ineffective in lubricating parts when cold.

Therefore, if you are going to rev, make sure that the oil and engine have heated up. This can vary depending on the weather outside. Drive at least 30 minutes before revving to be on the safe side.

Another thing to consider is “dropping the clutch” or putting an automatic car in drive at the high RPMs.

These two things are almost analogous to each other. But a significant difference is that you should under no circumstances put the car in drive when the RPMs are excessively high.

Dropping the clutch can be done without the incredibly high risk that the automatic has; however, it is still inadvisable.

What does dropping the clutch mean? It simply means that you rev up the engine while being in gear, pressing down the clutch to then viciously drop it, making your car launch.

This will affect the transmission, drivetrain, and other car components.

Another thing that you should avoid is to rev the car to the red line, which usually has a rev limiter installed to hinder even higher revs and more significant damage.

While the engineers set a good margin to protect the engine, revving and reaching the rev limiter at the red line will wear the engine components much faster.

Summary

Revving the engine is not necessary for your everyday commute. However, sometimes you would like to hear the engine spin or listen to your newly installed exhaust.

If done correctly, revving the engine will not negatively affect your engine, drivetrain, or any other car components.

Revving a manual is different from revving an automatic car, but they work on the same principle, disengage the gear in some way and press the gas pedal.

Make sure that the engine is heated to its operating temperature, as well as the engine oil. This is important for the protection of the engine components.

Avoid continuously revving at the red line, especially when the engine is cold.

If you drive a manual car, you can implement rev-matching, which will make your downshift very smooth and minimize the wear and tear of your transmission.

Can revving the engine in neutral cause damage?

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.

Why will the engine wear? (not an exhaustive list):

Piston compression ring expansion

Rapidly revving an engine will heat up the piston rings much faster. Because they have a much smaller thermal mass than the cylinder liners they expand at different rates. If the compression rings expand too much, they will generate increased friction on the cylinder liners, causing the cylinder liners to wear out (reducing compression).

In the worst case scenario, the compression ring ends touch, pinch the cylinder liner and will most likely cause the piston to crack. Then you’ll have metal fragments flying around destroying the head and cylinder.

On a very cold engine or while lean (not enough fuel), it is easier to get a larger thermal differentiation between the cylinder liner and piston rings.

Some early rev limiters implemented used a fuel only cut which could cause a cylinder to lean out “slowly” and develop a piston hot spot from detonation.

Contrary to other comments & answers given, the cooling system is NOT able to help, as piston failure happens within 4-10 milliseconds after a hotspot develops on a piston or compression ring. (See video for references to fuel injection millisecond times below)

Oil system starvation in wet sumps

More common in continued over revving – the cylinder head & block doesn’t drain the oil at the same rate that oil is pumped out of the sump, leaving the sump empty, common in the Rover V8 engines. This is very common in engines that don’t have the minimum oil required. Engines that are not serviced have dirty oil systems and are prone to blockages at high rpm.

This can also be caused if the block uses the same pipes to drain the oil that is also used to ventilate the sump causing oil vaporisation. However the engine would most likely already be overheating for this to occur.

Some poorly designed oil pumps (and water pumps too) can aerate and are unable to pump oil when increased in rpm too rapidly.

The next two points are much more common in performance engines where the manufacturer has tweaked output leaving no room for improvement. You’ll find plenty of videos on YouTube of motorcycles and Italian supercars revving without any load and destroying themselves.

Engines that can handle repeatedly being held on the rev limiter without any failure generally have a conservative rev limit set or have lots of performance parts available.

Connecting rod (conrod) warping

Some conrods will stretch/bend during excessive rpm acceleration. Worst case scenario is it will put greater unbalanced forces on the crankshaft and bearings (higher compression ratio only needs 10 thou). If the engine has tight tolerances it will also bend valves.

Crankshaft warping

The crankshaft or engine block isn’t designed to withstand such a sudden increase in internal force (similar to harmonic imbalances). It only takes a thou or two (0.0254 – 0.0508 millimetres) for the crankshaft to gouge a main bearing. This is common in performance & motorsport engines so they have increased strength built into the block by adding more ribs and webbing to the cast or billet.

If you’re curious what a “catastrophic” harmonic engine failure looks like at 11,000 rpm with load on a dyno, watch https://www.youtube.com/watch?v=1LkxGx5WJzA and skip to 15:55 where Cosworth gently explore the limit of their turbocharged 4 cylinder during F1 engine research & development.
