If you’re wondering why your car is so loud, you’ve come to the right place. This article will help you understand the different components of your engine, including the i-VTEC and CRX engines. While the engine can make minor noises due to injectors and accessory drive pulleys, the exhaust is by far the loudest part of your vehicle. VTEC improves fuel economy and power by using a more aggressive camshaft profile.

The i-VTEC system is a modified SOHC VTEC. The large lobe operates the intake valves directly, and the smaller lobe engages during VTEC. The result is a loud engine. The sound has been described by critics as “dancing about architecture”.

The change in cam profile is responsible for the increased loudness of the engine. The old B-series VTECs ran out of puff at around 6000 rpm, but the i-VTEC hits its redline at a range between 7400 and 8100 rpm. This makes the engine loud, but not too loud.


The reason why Honda CRX vtec is so loud is the DOHC motor. These are more efficient, which means more air movement. Also, the dual runner intake manifold has two sets of runners – one set of short runners and one set of butterflies. The VTEC solenoid is activated by the ecu and opens the short runners, which means more air is consumed by the engine.

While the engine is the main source of noise, the exhaust and intake are also significant sources of noise. Some minor noises can also come from the accessory drive pulleys and injectors. But the exhaust is the most recognizable sound. The VTEC system has a slightly more aggressive camshaft profile, which helps to improve fuel economy and power.


If you want to know why your CRV vtec is so loud, you should check the oil level in the engine. A leaky valve gasket could be the culprit. A broken thermostat or coolant level could also be to blame. In addition, your CRV vtec should have its spark plugs and air filter replaced every 15,000 to 30,000 miles. You should also check for any leaks in the oil and replace them if necessary.

Noise comes from two places: the intake sucking air and the exhaust. The exhaust, however, is the most noticeable noise. There are also minor noises from the injectors and accessory drive pulleys. The vtec technology in the CRV makes the exhaust more pronounced because of its aggressive camshaft profile. This allows more air to flow through the engine and boost its power and fuel efficiency.


A Skunk2 intake manifold is designed to produce the best VTEC sound possible. It uses three separate stages of operation. The first is low lift, the second is high lift, and the third is a combination of both. This results in a smooth and predictable torque curve. By contrast, a single-stage intake manifold would only amplify the effect of the cam lobe change.

The main reason a car exhaust is so loud is because of the amount of air it is sucking in. When the engine produces more air, it will emit more noise. A vtec exhaust manifold can increase this noise by increasing the amount of air going through the engine.

CRV turbo

The Honda CRV turbo VTEC engine produces a lot of noise. This noise is typical for any turbocharged engine. It is generated when the turbo is under pressure. Often, the cause of the noise is insufficient lubrication of the turbocharger mechanism. This can only be determined by a professional mechanic. In general, there will be a warning light on the dashboard if there is a problem with the turbo.

Another issue with the CRV is vibrations that occur from time to time. This issue is most prevalent in cold climates. Honda has produced a video explaining the problem and a technical service bulletin that details possible solutions.


If you’re wondering why your K24a VTEC is so loud, you’re not alone. The K24A is a gigantic engine, and that means it inhales MASSIVE amounts of air. The noise is so loud, in fact, that if you don’t have a proper intake muffler, it will blow your eardrums out. The K24A’s big, high-profile cams, starved primary cam, and massive secondary cam profile all combine to make a huge noise. Even though the K24A VTEC engages a lower camshaft angle than a typical engine, the noise is still very loud.

The K24a engine is quite reliable, and is capable of lasting over 200,000 miles. There are some problems that may crop up as the engine ages, but if maintained properly, the K24 will give you many years of trouble-free driving.
