Toms Supra Posted May 15, 2005 Share Posted May 15, 2005 I removed my HKS bov and put the standard one back on but without the recirculation pipe. I have found it dumps more freely gear change is smoother and quicker (auto) and it makes a long tussh noise rather than a high pitch sqeak like the HKS. I presume the HKS ones are quite restrictive thats why they make a high pitch sqeak rather than a low tuush like the standard one. Its not as loud but does seem better. Just thought i would tell others my findings! Quote Link to comment Share on other sites More sharing options...
Dragonball Posted May 15, 2005 Share Posted May 15, 2005 Sounds like the HKS may not have been set up right! Normally quite a large 'whossh' - depends on how tightly set? Quote Link to comment Share on other sites More sharing options...
Toms Supra Posted May 15, 2005 Author Share Posted May 15, 2005 Well most HKS ones i have heard are just a short high pitch sqeak. not just supras. so most be normal. I know blitz bovs make a long whoosh. Quote Link to comment Share on other sites More sharing options...
tepster Posted May 15, 2005 Share Posted May 15, 2005 tom, which one is the recirc pipe? adn what have u put there instead?? Quote Link to comment Share on other sites More sharing options...
Toms Supra Posted May 15, 2005 Author Share Posted May 15, 2005 right, the one under the small vacuum pipe heading towards back of car. you need a bung to go on the turbo manifold after you take it off though. I will get a pic if you like. Quote Link to comment Share on other sites More sharing options...
tepster Posted May 15, 2005 Share Posted May 15, 2005 pic if u could. I have the SARD r2d2 but may go back to the standard one if ur getting good results. When i ease of the accelerator just before the dump valve goes the damn red triangles light up on the dash along with the handbrake light. This may be due to unmetered air (from another post)so amlookin to resolve one way or another. Quote Link to comment Share on other sites More sharing options...
Homer Posted May 15, 2005 Share Posted May 15, 2005 As I've said several times before, IMO the HKS SSQV sounds shite, its best described as a high pitched squeak. The old style Blitz BOV I had was MUCH deeper and nicer sounding. Imagine that every time you take off even a little bit of throttle someone blows a whistle in your ear - well that’s the HKS for you... I'm now in looking to go back to a twin stock valve as the HKS one drives me nuts!! Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted May 15, 2005 Share Posted May 15, 2005 Personally I prefer the sound of the SSQV over a whooshing sound.. that reminds me of escorts and the like Quote Link to comment Share on other sites More sharing options...
Homer Posted May 15, 2005 Share Posted May 15, 2005 But the SSQV sound EXACTLY like the crappy BOV's seen with Escort/Fiesta/Cossie's as well as R5GT-T and small those type of small CC cars!! Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted May 15, 2005 Share Posted May 15, 2005 I think the SSQV sounds less like you're showing off than a lot of other BOVs I've heard. I can understand why some people don't like it but the whistle really doesn't bother me... then again maybe it's a lot louder on a BPU, I'm only running about 0.9bar at the best of times!
