REVIEWS & CUSTOMER MEDIA
This is a great replacement to the factory recirculating bypass valve, for those that want performance, without the noise that comes with a blow off valve. Installation was simple and the product is well built.
Product is of very high quality and fitted up very nicely to all the existing hoses (with no need for an extra bit of vacuum hose like the turbosmart one). To get maximum response the instructions say to keep adjusting the spring stiffer until you hear compressor surge and then back off a bit. If you have the standard airbox then it is almost impossible to hear the compressor surge. So a bit tricky to setup perfectly but thats not the bovs fault. If you have an aftermarket intake this will not be an issue.
Item is quality as usual from GFB so no problems there. Their own instructions say for maximum response to keep adjusting the spring stiffer until you hear compressor surge when lifting off the throttle and then back it off a bit. With it set to as stiff as it will go I cannot hear any compressor surge. So the spring is too soft for this application!! Very disappointed :(
