Scott Posted November 2, 2008 Share Posted November 2, 2008 Trying to diagnose whats going on with my second turbo. I may just have to bite the bullet and have them stripped off. Anyway, i've recorded a video of the strange noise that i get when coming off boost. Any ideas?? Gf8ZWBiYFyE Quote Link to comment Share on other sites More sharing options...
Dr_Doom Posted November 2, 2008 Share Posted November 2, 2008 I had a noise like that when my BOV was sticking and not working properly.. What BOV are you running? Have you got another one you can try? How does the car drive on full boost? Does it feel like there's a turbo problem? Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted November 2, 2008 Share Posted November 2, 2008 sounds like a fooked stock BOV to me... or a pigeon Quote Link to comment Share on other sites More sharing options...
Scott Posted November 2, 2008 Author Share Posted November 2, 2008 Its an HKS SSQV type 2. 2nd turbo doesn't come online at all Doom. When it should be coming on, 4000rpm ish, all boost is lost. I assume that there isn't any pre-spool and seems that the boost from the first turbo is rushing out through the 2nd one. I'm thinking either its a VSV problem or the 2nd turbo is cooked. I wanted to see if this noise had anything to do with it though. Cheers Quote Link to comment Share on other sites More sharing options...
