supraGZaerotop Posted October 5, 2017 Share Posted October 5, 2017 (edited) hi all, my car came with a hks ssqv, been on the car years. theres nothing wrong with it other than the fit has always bugged me a bit. find the hks fit is very close to the intake pipe and actually presses up against the link pipes. I just spent a few quid changing all these parts and so it thought I wanted something that fits in that space better while not rubbing up against other parts in my engine bay causing cosmetic damage over time. ive sort of made my own kit using a baileys dump valve and a pipe I bought and cut to size. the fit is pretty nice, I think I like it although I do like my hks, its hks right anyhow ive plumbed this lot in and it looks ok to me, ive not driven the car yet as I wanted some opinions on the bailey bov first. its this dump valve ok for the supra do you think, also I'm not sure if that filter thing that fits on the hks vac line kit is anything needed but ive not fitted it!!. here some pics. the last one is of my original config Edited October 5, 2017 by supraGZaerotop (see edit history) Quote Link to comment Share on other sites More sharing options...
ben_harmer32 Posted October 6, 2017 Share Posted October 6, 2017 I switched back to the standard recirc valve on mine. Car ran a lot better and still had a whoosh sound due to aftermarket intake Quote Link to comment Share on other sites More sharing options...

supraGZaerotop Posted October 6, 2017 Author Share Posted October 6, 2017 anyone used a bailey valve on they're supra? Quote Link to comment Share on other sites More sharing options...
squiffy Posted October 6, 2017 Share Posted October 6, 2017 If it's the sound you're after, the Bailey will sound a lot better then the hks "chirp" imo Quote Link to comment Share on other sites More sharing options...
supraGZaerotop Posted October 6, 2017 Author Share Posted October 6, 2017 (edited) do you think so? interesting. il have to take it out for a drive when i get back home. does it make any difference not having the vac filter, i assume thats what it is that comes with the hks bov. like an inline flying saucer lol- whats it for? because the way this bailey fits there is only need of a very short length if hose Edited October 7, 2017 by supraGZaerotop (see edit history) Quote Link to comment Share on other sites More sharing options...

Ric Posted October 7, 2017 Share Posted October 7, 2017 remove it completely gives the chattering sound, It's cool, gets annoying quickly i think and still some debate whether compressor stall causes issues over time? Quote Link to comment Share on other sites More sharing options...

supraGZaerotop Posted October 7, 2017 Author Share Posted October 7, 2017 bk in 2004-2008 i owned a s14a 200sx. loved that car. had it up to about 300hp front mount, fuel pump, fcd, colder plugs, boost controller, intake, complete double decat. tubular manifold, new turbo, was a flying machine i use to have a sard r2d2 bov fitted, and sometimes id disconnect it to get the flutter and i loved the noise way more than than the bov noise. soon as i started reading about compressor stall i stopped with the flutter Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted October 7, 2017 Share Posted October 7, 2017 (edited) soon as i started reading about compressor stall i stopped with the flutter Recirculation valves are fitted by manufacturers to stop the noise of compressor stall. I've never seen any evidence to backup the claims of increased longevity of a turbo nor have I seen a turbo killed because the engine wasn't running a BOV. Chris Wilson doesn't run a BOV on his race Skyline which pretty much says it all for me. Every International Group C sports car to 1991 no BOV Every F1 car from 1979 to 1988 no BOV Every Indy car from 1970 to 2006 (maybe beyond) no BOV DJR Group A Sierra till its last races no BOV Nissan say they only run one to reduce noise. The CA18DET has no BOV. If you have a look at the engines that have had them fitted, you will notice that they got fitted at the factory after the new/tighter noise and pollution restrictions came out. But if you like the sound get one Edited October 7, 2017 by Frank Bullitt Spelling. (see edit history) Quote Link to comment Share on other sites More sharing options...
supraGZaerotop Posted October 8, 2017 Author Share Posted October 8, 2017 i do miss the flutter, so much better sounding than a blow off valve. i take it all id have to do to blank it is removed the bov all together and buy a 25mn cap for the ypipe side and blank off the vac feed? whats the best way to block off the vac line!

supraGZaerotop Posted October 11, 2017 Author Share Posted October 11, 2017 well for some reason my supra didint seem to like that bailey valve much. just seemed to boost funny. valve was running fine on idle and seemed to be running fine. anyway changes bk to hks now. much better Quote Link to comment Share on other sites More sharing options...
