bigbloodyturbo Posted March 12, 2009 Share Posted March 12, 2009 My Sard bov is not as in yer face as some, also looks quite good under the bonnet. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 12, 2009 Share Posted March 12, 2009 Stock one? It's a re-circ one but does the job without making the car sound like a bus. Also, it'll be fine without one so no need to worry. Quote Link to comment Share on other sites More sharing options...

Also, it'll be fine without one so no need to worry. are you sure it will be fine? i read this in the FAQ's: When you take your foot off the accelerator to change gear or whatever there is suddenly a lot of pressurised air from the turbos that has nowhere to go as the throttle plate is shut. A BOV is a valve that is triggered by the pressure difference in the manifold and gets rid of this excess air. If this didn't happen it would cause the turbos to suddenly stop spinning, which would not only knacker them in short order but mean they had to spin up from a standstill when you got back on the throttle again.

Nic Posted March 12, 2009 Share Posted March 12, 2009 are you sure it will be fine? As Homer says it'll be fine without one. The most popular aftermarket BOV is the HKS SSQV, there is a kit specifically to fit the Supra, easy DIY job to install. I have in stock, give me a shout if you would like prices.

mikeyb10supra Posted March 12, 2009 Share Posted March 12, 2009 I capped mine off about a year ago now. Some people worry about the compressor still producing boost after the throttle has been closed and it having no where to go, but mine has been fine to date. You might get a chattering sound if you dont have a stock intake and panel filter. Mine is slightly muffled becuase of this but some people like it Quote Link to comment Share on other sites More sharing options...

SimonT Posted March 12, 2009 Share Posted March 12, 2009 You can change the sound of an SSQV as well by changing the inserts to them! Dont think its a huge different just a slight change! Quote Link to comment Share on other sites More sharing options...

Hi Nic, Could you pm a price for one of these please. Do these sound different on Autos and manuals? Quote Link to comment Share on other sites More sharing options...

SimonT Posted March 12, 2009 Share Posted March 12, 2009 Do you mean the loudness or the pitch? From what i have read its the pitch?! I think Nic knows about them as im sure he has posted up a video before of the different sounds with the different inserts? Quote Link to comment Share on other sites More sharing options...
