MarkR Posted August 17, 2007 Share Posted August 17, 2007 Or you could look at this? http://www.envyperformance.com/index.cfm?fuseaction=product.display&Product_ID=5087 My vvti does the same thing. Backfires when I lift off after fitting the SSQBOV. I'll be calling Gaz/Kevin on Monday... Quote Link to comment Share on other sites More sharing options...
styggen82 Posted August 18, 2007 Share Posted August 18, 2007 Maybe not blown it up YET, however there have been people who have had issues with MAF equipped cars (UK's and VVTi's), who have had hassles with atmospheric BOV's. Is just one example.. I personally have experienced this on my VVTi as well. Please note the comment regarding detonation...... I`m experience the same after I fitted a Tial BOV on my 98vvti TT... not very often but sometimes I get a some unburnt fuel in the exhaust... a couple a times a month maybe... but how is this affected if you run bpu and 1,2 bar boost? regarding the fuel mixture that you might have problems with on J-spec supas? I`m no expert but hopefully somebody knows? Quote Link to comment Share on other sites More sharing options...
Nic Posted August 18, 2007 Share Posted August 18, 2007 I`m experience the same after I fitted a Tial BOV on my 98vvti TT... not very often but sometimes I get a some unburnt fuel in the exhaust... a couple a times a month maybe... but how is this affected if you run bpu and 1,2 bar boost? regarding the fuel mixture that you might have problems with on J-spec supas? I`m no expert but hopefully somebody knows? The VVTi Supra uses a MAF (Mas Air Flow) Sensor, this is mounted in the intake and measures the amount of air going into the engine. This measurement is sent to the ECU which adjusts the fueling accordingly. The problem with a vent to atmosphere BOV on a car with a MAF sensor, is that it releases this measured air from the system, which causes the engine to run rich.

Cool, thanks Nic Hope no offence was caused earlier by saying I was going to Envy, but I thought you'd have mentioned the recirc kits if you knew about them..

MarkR Posted August 29, 2007 Share Posted August 29, 2007 Just an update! Refitting the original Toyota BOV in mine has worked a treat. Feels like a new car again The power is far more stable, no dips and surges etc, just smooth power delivery all the way! Anyone with a VVTI might wanna rethink the vent to air BOV's.

Pete Posted August 30, 2007 Share Posted August 30, 2007 I've just received my recirc kit in the post and will have a play when I get chance. I will probably end up going back to stock. Quote Link to comment Share on other sites More sharing options...
