lee_kelsey Posted July 18, 2002 Share Posted July 18, 2002 Guys, I bought the SSQV from Justin at the weekend, I got round to fitting it yesterday, and it sounds the badgers balls! Anyway, I noticed when taking the car out for a run, (to make sure all was ok!) that it appears to have increased my boost quite considerably! I normally have my boost controller on 50% which runs about 1.0/1.1bar. While I was blasting it down the road, my limiter started beeping. I have this set at 1.3bar! I turned it down to 40% boost and it was peaking at around 1.2bar. I lowered it to 30% and its now reading about 1.0bar. I couldn't believe that this new bov would have made such a difference! What do you guys think? and how can I work out a safe pressure to run my turbos at? cheers Quote Link to comment Share on other sites More sharing options...
Adam W Posted July 18, 2002 Share Posted July 18, 2002 It sounds like your old BOV was starting to open under boost, and some the air was escaping through it - hence, your turbos were working really hard but some of that air pressure was being squirted out into your engine bay.

Dragonball Posted July 18, 2002 Share Posted July 18, 2002 Lee Excellent M8 - Very interested in hearing the noise that your BOV is making! Apart from Boost readings has it improved performance? If not at Billing - you around next Friday? Cheers Paul Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 18, 2002 Share Posted July 18, 2002 FWIW whilst dynoing my engine the HKS SSBOV was found to be leaking badly. The Blitz one was fine. Quote Link to comment Share on other sites More sharing options...

Terry, this is a reply from Justin F about the bov, may explain the problem you found! ********************************************* Glad you like the dump valve, glad it arrived on time, this is the sort of service you should normally receive from me. The bolt at the back of the SQV is for fine tuning the spring strength. On cars with MAF sensors (like UK supras), it is possible for the car to stall if the spring strength isnt enough (to increase wind the bolt in). loosening the bolt, should increase dump valve volume and response, too lose and you may have stalling problems or (I think) it may leak boost pressure. Try unwinding the bolt a little and see what the results are. ********************************************* Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 19, 2002 Share Posted July 19, 2002 If only! The bolt had to be closed completely to stop the thing leaking. I am on an anti HKS trip at the moment as I currently have faulty: HKS SS BOV HKS Cam Gear ( Teeth wore down & destroyed the belt) HKS GT Wastegate ( The thing turned up with a hole in the diaphragm!)

tDR Posted July 19, 2002 Share Posted July 19, 2002 I always did like Blitz Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 19, 2002 Share Posted July 19, 2002 The new Blitz one works faultlessly. I may replace the HKS with another Blitz on soon. Quote Link to comment Share on other sites More sharing options...
