Car drivers often get into the VTEC engines while driving a Honda, but do you know how they perform?
Can you tell us when VTEC kicks in? At what RPM? Typically, while engine speeds are maximized, oil pressure builds inside a piston within the rockers, locking 3 cams together to ensure maximum valve lifting.
This source indicates a “VTEC kicking in” noise. VTEC, however, tends to perform between 4000 and 5500 RPM, based on the engine’s condition, oil pressure, and other factors.
Every rider finds the sensation of increased performance with high efficiency to be particularly thrilling. So we closely check for the moment when the VTEC kicks in. Plus, this article will share how you should utilize the engine like a pro!
What Is the Function of the VTEC Engine?
Before we talk about when VTEC kicks in, we should know how this engine performs. Let’s have an easy introduction to Honda’s VTEC technology.
- In general, the VTEC system is equipped with an engine with various camshaft profiles for low and high RPM operations.
- Rather than a single camshaft controlling each valve, there are two: one intended for low-RPM stability and fuel efficiency, and a second built to enhance high-RPM energy production.
- Commonly, the VTEC moniker is used to refer to any variable valve system that Honda includes.
When Does VTEC Kick In? At What RPM?
Who doesn’t celebrate seeing the kick in time for excitement? Basically, this engine lengthens the time, and the intake valves are left uncovered at high RPM.
The way two camshaft profiles provide power and fuel economy to drive the engine, like Achilles from the Trojan War! Incomparably powerful! However, let’s clarify the exact RPM and the exact time you get the kick!
At What Speed Does VTEC Activate?
VTEC activates based on engine temperature, oil pressure, and other aspects. Though it varies from car to car and how you drive your car, it usually kicks off at 4000 to 5500 rpm.
The VTEC engine consists of two value profiles. One is a regular car, and the other is a sports car. When you think of a racing car, you may notice that its valves are more suited for use at high RPM than low RPM.
On the other hand, a normal car operates smoothly at lower RPMs because it is designed to create greater torque at lower RPMs.
What RPM Does VTEC Kick in K24?
For K24, the maximum kick is 8000 RPM. The K24 intake valve must flow 63 times per second. Therefore, the intake valve must be opened an absurd number of times each second to reduce the speed.
When Does VTEC Kick in FK8?
As the FK8 has a turbocharger, VTEC works in a different style. The turbocharger engine removes hot gases so that fresh air may be given for burning. This can improve the performance of your vehicle.
When Does VTEC Kick in Civic EX?
The previous generation’s Civics started at roughly 3,000 RPMs; however, the current Civics have no noise and start at around 4200 to 4500 RPMs.
It tends to vary by the engine, but in most cases, it kicks in at 5500 RPM. The interesting fact is that it feels like nothing. There is a small bump when it happens, but usually, you don’t feel anything.
What Causes VTEC to Activate?
If you are a car lover, definitely you’re familiar with VTEC kick. Everyone has gone through this. However, it is based on how you drive. When oil pressure increases, the engine’s VTEC activates and starts to kick in. Sometimes you might be low on fluid, which also causes VTEC to kick in.
What Causes VTEC Failure?
Each part of the vehicle must function properly to keep it in good condition and running smoothly. It’s actually frustrating if one of those parts does not work properly. Things are common when VTEC fails. let’s have a look at the common causes of VTEC failure.
- Low oil pressure
- Incorrect VTEC wiring or the wrong wires
- The temperature of the engine
- ICM or internal ignitor problem
- Check the light of your engine
How Do I Fix VTEC System Failure?
The VTEC system failing is a common issue for every rider. When it fails, the engine may lose its power and efficiency. The following strategies can be used to repair the issue.
- Due to oil pressure, this problem occurs. If possible, try to replace the oil and filter it
- If necessary, change the VTEC solenoid wires and other parts. As it is difficult to change, try to consult with experts
- Throughout these checks, if you discover any flaws, replace those items.
How do I know when my VTEC kicks in?
VTEC really improves the sound of the engine; therefore, it is necessary to know how to get it to kick in. However, you should know some facts like:
- The engine needs to run at a higher RPM to make DOHC or VTEC kick in
- It is supposed to kick in around 5000 RPM or 5800 RPM (May vary from vehicle to vehicle)
- As soon as you press VTEC, the volume gets loud
But it’s not like the B series. It has a smooth, steady tone. Although there isn’t much of a change in sound, after some time, you’ll notice that the throttle needs to be turned in farther than halfway before it begins to work.
Just press the gas pedal all the way down. And at 5000 RPM, the DOHC or VTEC kicking in sound should begin to become noisy.
Check out this frequently asked question for further clarification on VTEC kick-in issues.
Q: Does VTEC make a car faster?
Yes, the Honda VTEC engine speeds up and boosts overall performance on uneven surfaces while providing an enjoyable, comfortable ride. Additionally, VTEC changes the cam profile to provide more power and better engine breathing.
Q: Is it safe to tune or remap a VTEC engine to make it kick in at about 4500 RPM?
Yes, it’s safe. In most scenarios, engines can be rebuilt or remapped. In general, engines are set to start at about 4000 RPM. Hence, by reprogramming the engine, you can make it kick in at around 4500 RPMs by investing money.
Q: At what RPM does VTEC kick in on a Gen 2?
Both of the intake valves use the middle section of the camshaft when the second VTEC solenoid operates from 5500 to 7000 RPM. Also, it was uncovered that the latest Si’s VTEC shows up at 5800 RPM.
Honda invented the VTEC engine to operate far better with a wide RPM range than any other engine in the industry. So, we riders get excited about when does VTEC kick in? At what RPM? Note 3000 to 5500 RPM as the kick-in time that we commonly notice, but conditions may vary the RPM level.
Whether it’s a k24, FK8, or Civic, VTEC Engine will give you goosebumps in a certain period of time and you’ll be crazy experiencing that moment. However, discovering the failure of VTEC kick-in, the fixation has been shared above.
