JohnK Posted May 3, 2006 Share Posted May 3, 2006 Ive only heard of a couple of people getting away with an atmospheric BOV on a UK auto. I certinly had the stalling issue and unless you have something like an e-manage to compensate I wouldnt bother. Quote Link to comment Share on other sites More sharing options...
Sharpie Posted May 3, 2006 Share Posted May 3, 2006 what if you run twin BOV's ? i.e. stock one and HKS one ? Quote Link to comment Share on other sites More sharing options...
AntD Posted May 3, 2006 Author Share Posted May 3, 2006 Thanx for the reply mate.I suppose I best be looking at getting a new stock BOV then... Quote Link to comment Share on other sites More sharing options...
JohnK Posted May 3, 2006 Share Posted May 3, 2006 what if you run twin BOV's ? i.e. stock one and HKS one ? You're still venting metered air out of the system. Quote Link to comment Share on other sites More sharing options...
Sharpie Posted May 3, 2006 Share Posted May 3, 2006 true - I hope to have my SSQV fitted very soon to see if I have this problem also - bit by bit prepping for single If I do, I can just swap out the IC pipe for the current one and move back to normal.

JohnK Posted May 3, 2006 Share Posted May 3, 2006 What ECU are you planning on when you go single? As far as I know the SAFC cant do anything with atmos BOV E-manage blue has a workaround which is acceptable but not perfect. E- manage ultimate I would imagine has the same or better than the blue, it is possible to remove the MAF with this but I dont think anyone has got it working 100% yet. Anything better than that will be standalone and do away with the MAF anyway, so no more problem. Quote Link to comment Share on other sites More sharing options...
Alex Posted May 3, 2006 Share Posted May 3, 2006 HKS do an IDLE Stabilizer...I've seen them on EVO's for atmospheric BOV's but I've not seen one on a Supra. If an HKS Idle Stabilizer can be fitted, then this will allow a atmos bov on a MAF based car. The reason it stalls is because the MAF measures the air coming in at the filter....the air then travels through the turbo and onto the throttle....the BOV is mounted post turbo and so if an Atmospheric BOV releases the measured air into the engine bay instead of keeping it in the system. But the ECU's still expecting it and so it adds enough fuel to compensate for the amount of air that SHOULD be there...only for it to actually flood the engine because naff all air actually turned up. MAP based Supra's measure air at the plenum (intake mani) and so don't suffer this issue. Why can't you move the MAF to be post BOV?? Because it measure's temperature too. It's calibrated to measure the temperature of the air at the filter, not turbocharged and therefore HOT air. Also, you'd suffer REVERSION. When the throttle slams shut you'd get a double air reading as the air that just passed through the MAF bounced back and races to the BOV to escape. This would double the amount of air registered.

Sharpie Posted May 3, 2006 Share Posted May 3, 2006 John, if you questions are at me - I'm not 100% sure right now but, am leaning towards a standalone. Oh, I also have the HKS SSQV Re-circ kit too so, have all option available to me during testing. Quote Link to comment Share on other sites More sharing options...
Sharpie Posted May 3, 2006 Share Posted May 3, 2006 HKS do an IDLE Stabilizer...I've seen them on EVO's for atmospheric BOV's but I've not seen one on a Supra. Good info Alex! Sounds like a job for our resident Pimp to source HKS EIDS ~ $135 http://www.hksusa.com/products/?id=2175 http://www.hksusa.com/images_products/L_2307.jpg Quote Link to comment Share on other sites More sharing options...
