max55uk Posted November 19, 2007 Share Posted November 19, 2007 Hi Guys, Just fitted the mk2 HKS SQQV Dump Valve to my Twin Turbo 1997 vvti, i have checked all the pipes everything is fitted according to the diagram, The car boosts normal, no missing, even when its idle its fine. However i can hear a whining noise when the car boosts. Just wondered if anyone else has had any similar problems? Cheers Quote Link to comment Share on other sites More sharing options...

mikeyb10supra Posted November 20, 2007 Share Posted November 20, 2007 if its a uk mate....could be the dreaded death whine I would check all boost hoses first though to rule that out Quote Link to comment Share on other sites More sharing options...
jaymdee Posted November 20, 2007 Share Posted November 20, 2007 How loud is it? As you always hear the turbos when they spool up Quote Link to comment Share on other sites More sharing options...

mikeyb10supra Posted November 20, 2007 Share Posted November 20, 2007 yep...if they are UK turbos they could be on there way out http://www.mkiv.com/techarticles/dea...eath_whine.wav http://www.mkiv.com/techarticles/dea...deathwhine.WMV Quote Link to comment Share on other sites More sharing options...
Class One Posted November 20, 2007 Share Posted November 20, 2007 It's a 97 vvti so not a UK then. Have you changed your intake at all. Some aftermarket intakes make the spooling noise of the 1st turbo more prominent. Quote Link to comment Share on other sites More sharing options...
max55uk Posted November 20, 2007 Author Share Posted November 20, 2007 Pics bellow, well the car has an HKS Induction kit and before all you could hear was the Induction Noise but now thats disapeared and instead i'm getting a whiny noise, its not a quite spool on both turbo's, the car has been modded, HKS FMIC, HKS Fcon V, Oil Cooler, Exhaust, Blitz power reader which displayed 370ps @ 140mph and i let go..lol Might be Uprated Turbo's? as its set to run @1.1 bar boost, i might just get rid of the D/V and back to standard, Quote Link to comment Share on other sites More sharing options...
Pete Posted November 20, 2007 Share Posted November 20, 2007 Well for one thing you've not fitted the recirc kit which the VVTi requires for the MAF sensor not to get so upset. If you fit the MAF sensor you won't hear the pssssh much though.. I had one and removed it as the car drives so much better with stock setup.

mikeyb10supra Posted November 20, 2007 Share Posted November 20, 2007 It's a 97 vvti so not a UK then. Whoops I missed that first time round....I was going by his username that had UK at the end Quote Link to comment Share on other sites More sharing options...
