User Description: Growling - happens when debris in the supercharger causes the rotor to hit the housing. Clacking - then there is an idle issue if this condition is present at idle but goes away under load. Then the coupler may be damaged if the issue continues after engine rev. Whistling - Supercharger units produce a whistling sound through the atmosphere going through the system though in the event that sound is very loud there might be vacuum pressure drip. Gear Whine - Gear whine is normally as a result of age but the majority commonly takes place as soon as the unit is run without oil. Sound Increase - A smaller pulley will generate more noise as a result of the increased motion of the atmosphere through the system. Simply Noisy - several times the supercharger is blamed for noise and has to be examined by hand to find out when it is certainly the origin of the sound. Vibration - this is certainly never ever due to the supercharger unit considering that the device is balanced. The vibration may be the engine. Of course with any part it is a idea that is good have the car inspected by a certified mechanic before making a decision about fixing or changing a supercharger product. Hey guys, I simply bought a 2005 cobalt ss a couple of months ago and was wondering making the supercharger whine louder. The vehicle is 100% stock with no gm stage upgrades. We saw a ss yesterday evening at a car show when he left the supercharger sounded pretty sweet. Is it just an after market consumption system that makes the noise? I have to get different injectors and retune the computer if I change the intake does that mean? I no nothing about these computer automobiles. We race a 9 vette that is second the strip but its a carbohydrate setup so going from that to this is foreign if you ask me. We do not want to get too crazy with this specific automobile since it is my daily driver but if there exists a easy mod I'm able to accomplish that makes the vehicle whine I would want to get it done. By simple I dont mean inexpensive after all effortless. To learn about This Site and their explanation, check out the website her latest blog. I've read in reviews, and heard on my very own try out, that the S4's Supercharger is very quiet, in the verge of being invisible. I have constantly enjoyed the noises my cars make. Hell, one of many mods I became planning for my STI was gears that are straight-cut because I loved the noise. Are you able to alter the car to obtain that Supercharger sound right back? I am aware on my past Turbo automobiles, removing the consumption Silencer would do miracles for the induction noise, but my only Supercharged car, a Toyota Tacoma, has already been quite loud, and so I don't have much experience with them. Then you should look for a good cold air intake if you want to get more supercharger whine, without making anything else louder. People choose to fit an Alta cool atmosphere intake kit – because these are the loudest. Important advice from fosterscmods there is usually a synthetic filter behind the intake, and if you remove our when fitting a intake that is new will also make the supercharger sound louder. making supercharger whine louder Incorporating a pulley can make the supercharger also whine sound clearer. They can be a good alternative to an Alta – but any cold air intake will probably make a difference if all you have now is the stock fitting if you can source an H&K. In the event that you fit simply the pulley, without the intake, you will probably notice some huge difference to how the vehicle noises but it'll be slight. It’s a tiny improvement in pitch and volume and never the clear but smooth whine that most individuals are searching for once they fit a cold air intake kit.
