terribleturner Posted May 10, 2005 Share Posted May 10, 2005 It will allready make a very quite whoosh noise, but yes you can upgrade it later. A very easy job that takes no time to do. Quote Link to comment Share on other sites More sharing options...
ADD Posted May 10, 2005 Author Share Posted May 10, 2005 am i right in saying that air i just recirculated round again? are you not able to take a pipe off so the air is forced out?? hence the noise Quote Link to comment Share on other sites More sharing options...

ArghJae Posted May 11, 2005 Share Posted May 11, 2005 Glenn, Can your mod be done on a UK spec car? Quote Link to comment Share on other sites More sharing options...
crimbo Posted May 11, 2005 Share Posted May 11, 2005 i need to know too please........ Quote Link to comment Share on other sites More sharing options...
Nic Posted May 11, 2005 Share Posted May 11, 2005 Glenn, Can your mod be done on a UK spec car? Venting the BOV to atmosphere is not advised on a UK car, due to air flow sensor. Doing so could result in incorrect A/F mixture. Not a problem on J-spec cars as these use an air pressure sensor instead. Quote Link to comment Share on other sites More sharing options...
geoffvalenti Posted May 11, 2005 Share Posted May 11, 2005 UK cars (and VVT-i J-specs) use a Mass airflow meter to control the fuelling. While it's possible to do the mod, its inadvisable because, AIUI, you'll be dumping metered air, causing the engine to firstly run rich, and then lean. CW did post a much more informative article about this a while ago. Its probably worth doing a search if you want to know all the ins and outs. J-spec cars are OK with dump to atmosphere BOVs (If you like the sound ) Quote Link to comment Share on other sites More sharing options...
Suprasteve Posted May 11, 2005 Share Posted May 11, 2005 i done the little mod that makes the standard 1 go whooooosh Have you just unplugged and blocked off one of the pipes ? Apart from the noise are they any other differences ? Quote Link to comment Share on other sites More sharing options...
Jake Posted May 11, 2005 Share Posted May 11, 2005 i done the little mod that makes the standard 1 go whooooosh What's the point of this mod? Does it improve performance in any way or is it solely an attention seeking device? Quote Link to comment Share on other sites More sharing options...
LeeT Posted May 11, 2005 Share Posted May 11, 2005 What's the point of this mod? Does it improve performance in any way or is it solely an attention seeking device? i could never understand the appeal of a dump valve either. ive only replaced the stock one now because i had to.

GlennMR2 Posted May 11, 2005 Share Posted May 11, 2005 no improvement in performance i just like the sound. i guess that makes me a barry boy then Quote Link to comment Share on other sites More sharing options...
Jake Posted May 11, 2005 Share Posted May 11, 2005 I guess you're right. Quote Link to comment Share on other sites More sharing options...
wez_p Posted May 11, 2005 Share Posted May 11, 2005 replacing the stock airbox with an induction kit will also make it more noticeable (but nothing like a proper atmospheric dv) you also get alot more whistling noise from the turbos and the air being sucked in sounds like a hoover sometimes!

Bobbeh Posted May 11, 2005 Share Posted May 11, 2005 Yeah, I've got the HKS on mine.. tbh it doesnt sound much running with stock boost anyway. Might be getting rid of it in the near future. Quote Link to comment Share on other sites More sharing options...
Kopite Posted May 11, 2005 Share Posted May 11, 2005 it is a bit pointless replacing them unless it's necessary, i still changed mine though! anythin to try and make myself look cool Quote Link to comment Share on other sites More sharing options...
JohnK Posted May 11, 2005 Share Posted May 11, 2005 And don't go thinking an e-manage's anti stall feature will help you, far more trouble than its worth on a UK car. Quote Link to comment Share on other sites More sharing options...

Bobbeh Posted May 11, 2005 Share Posted May 11, 2005 far more trouble than its worth on a UK car. I dunno why you keep saying this, I've had no problems at all, neither do any of the thousands of people who use them in the US. Quote Link to comment Share on other sites More sharing options...

Have you had the A/F mixture checked to make sure you are not getting overfueling/underfueling? Dusty at MVP recommends that a recirculation kit is fitted if fitting the SSQV to US cars still running MAF Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted May 11, 2005 Share Posted May 11, 2005 I've had it dyno'd since having it fitted. No problems at all. Does anyone actually KNOW of a UK spec supra with problems... or all this based around the MR2 that was originally spoke of. I'm not disagreeing with the logic etc.. I've just not heard of any Supra in this country with issues. Quote Link to comment Share on other sites More sharing options...
Toms Supra Posted May 11, 2005 Share Posted May 11, 2005 I might try that mod on mine, see how it compares to the HKS. Coz the HKS dont sound that good to me. Quote Link to comment Share on other sites More sharing options...
Geezabloke Posted May 11, 2005 Share Posted May 11, 2005 Again, ive an HKS BOV on my UK, had it set up wit THOR and dialled out the rich side on my AFSC. The graph / plot showed no signs of running lean? However i have heard of UK cars stalling with after market BOV's? Dave Quote Link to comment Share on other sites More sharing options...
Ian C Posted May 11, 2005 Share Posted May 11, 2005 The stalling phenomenon definitely exists, but anti-stall features aren't simply and "on or off" thing, if set up wrong they will cause as many stalls as they save. I'm chatting to John offline to see if I can help -Ian Quote Link to comment Share on other sites More sharing options...
JohnK Posted May 12, 2005 Share Posted May 12, 2005 The anti stall is a big compromise that takes a LOT of fine tuning, stalling an auto is a major PITA. The MAF sensor is a weakness in the UK car as it creates problems when modding the car. Having a UK car has many advantages but I will not defend it to the hilt if I think it has a weakness in an area being discussed. Also worth noting is that my BOV is fully plumbed in and I still get the odd lift off stall, I have the anti-stall set up almost right now but it takes a lot of time to get it right. The e-manage itself is a great piece of kit that I whole heartedly recomend, but I pity anyone who thinks they can just fit and forget these things.
