Chris Wilson Posted June 24, 2008 Share Posted June 24, 2008 I have never run a BOV in all the years I have been running turbo engines. They WERE designed as noise suppression devices, and if they gave less lag and longer turbo life would they not be fitted to F1 engines when they ran turbos (they were not...) or Indy car engines with turbos (they are not....) or the Group C cars (they were not...)?

Gaz6002 Posted June 24, 2008 Share Posted June 24, 2008 Good thread. I'm going to get rid of mine soon. The noise makes me cringe every time I come off throttle. Quote Link to comment Share on other sites More sharing options...
bignum Posted June 24, 2008 Share Posted June 24, 2008 Its not compressor surge though is it, Quote Link to comment Share on other sites More sharing options...
miko_supra Posted June 24, 2008 Share Posted June 24, 2008 Hmm interesting...I can see why they would be put on commercial cars as the general public isn't interested in odd noises on their new expensive cars Quote Link to comment Share on other sites More sharing options...

Pabs Posted June 24, 2008 Share Posted June 24, 2008 interesting read! Anyone running a supra without any BOV at all, and got info on the best way to do it? Might be worth a test to see if mine is actually leaking or not... Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted June 24, 2008 Author Share Posted June 24, 2008 Mine is going soon as im sure its the recirc leaking interesting read! Anyone running a supra without any BOV at all, and got info on the best way to do it? Might be worth a test to see if mine is actually leaking or not... just cap off all ports that the stock BOV uses....job done Quote Link to comment Share on other sites More sharing options...
Pabs Posted June 24, 2008 Share Posted June 24, 2008 just cap off all ports that the stock BOV uses....job done thanks mate - my ssqv is in the standard bov position, so if it's removed I'll just plug up all of the hoses going to it then Quote Link to comment Share on other sites More sharing options...
Ric Posted June 24, 2008 Share Posted June 24, 2008 so the myth that running a Turbo engine without a bov can damage it is twoddle, ok Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted June 24, 2008 Author Share Posted June 24, 2008 thanks mate - my ssqv is in the standard bov position, so if it's removed I'll just plug up all of the hoses going to it then to be honest, I would just leave it. I only got rid of mine as the noise was getting on my nerves but it worked a damn site better than my stock recirc and didnt leak Quote Link to comment Share on other sites More sharing options...
robin Posted June 24, 2008 Share Posted June 24, 2008 Any ideas on the best method to cap the hoses though? Quote Link to comment Share on other sites More sharing options...
Scott Posted June 24, 2008 Share Posted June 24, 2008 Broomstick or get/make a proper plug. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted June 24, 2008 Author Share Posted June 24, 2008 Any ideas on the best method to cap the hoses though? just order 2x19mm rubber ferrules and jubilee clip them on....the actuator line will need a much smaller nipple to go over the top but not sure on the size of the top of my head. But if your stck recirc is working ok I wouldn't bother changing it Quote Link to comment Share on other sites More sharing options...
Andy Blyth Posted June 24, 2008 Share Posted June 24, 2008 I found that a 1/2" (female) to 3/8" (male) socket adapter fits nicely in the stock BOV pipework. Add a jubilee clip and jobs a gooddun. FWIW, I find the sound of the Supra with no BOV pretty undesirable. It's just lots of oscillating wategate sounds. Interestingly, you also get a "tschh" sound that it remarkably similar to the stock BOV when recirculating. Quote Link to comment Share on other sites More sharing options...
Pabs Posted June 24, 2008 Share Posted June 24, 2008 the only reason i wanted to remove mine was to see if it was leaking and causing lower than expected boost/power figures. But I'll see how I get on with other things first I think! Quote Link to comment Share on other sites More sharing options...

steb9780 Posted June 24, 2008 Share Posted June 24, 2008 I work with Cord from the GTR register, he also works at RB motorsport and built Keith Cowies engine. He says bin it. I remember him also saying something to do with 360 degree bearings. It was when I asked him about the BOV on my Rover Coupe Turbo when I fitted my GT28R blower to it.
