May 31, 200916 yr Just wondered if there is a way to make the standard dumpvalves more noisy, as i have changed my mind about fitting aftermarket ones as i want to keep her stock. Not fussed if theres not a way just wondered. thanks
May 31, 200916 yr you cant make them louder as they are recirculating ones - the boost is held in pipes and fed back into the turbos (highly technical there!) when youre back on the throttle. aftermarket ones are atmospheric dump valves, where the boost is dumped into the air (and therefore audible). is your motor an auto or manual mate?
May 31, 200916 yr 92 uk manual i was going to say if it was an auto it might not be worth having aftermarket BOVs installed because the car changes up through the gears without the need to back off the throttle, so the only way to get an auto to dump is to literally throttle off (pssshhht), then throttle on, then the car changes up!
May 31, 200916 yr Author oh ok mate, think i'll leave her as she is for know then, as my to do list is big enough already lol. thanks Dom
May 31, 200916 yr i did! if you remvoe the pipe on the standard re-circ, the one that goes from the valve to the air intake, and block the ends up, the re-circ turns into a HKS SSQV sound!
