ColdScrip Posted December 10, 2010 Report Share Posted December 10, 2010 Doing a car up as a daily driver. The idea is MPG, reliability, etc. Would you recommend a BOV or not? I am stuck debating because:1. Compressor Surge2. Possible chance of leaking3. Running rich inbetween shifts Ideas? Link to comment Share on other sites More sharing options...

patra_is_here Posted December 10, 2010 Report Share Posted December 10, 2010 well, run the BOV. since, if you're concerned about mileage, that means you wouldn't be flooring it, which means you wouldn't be building boost, which means you don't need to worry about running rich between shifts killing your gas mileage, because if you're not building boost, there's not going to much for the BOV to blow off. follow the logic? theres absolutely no real debate. if you are concerned about reliability, and you plan on sometimes 'wasting fuel' by driving heavy footed, then the reliability of a BOV and the chance of it sticking greatly outweighs the failure that would occur from bad compressor surge. compressor surge shortens the life of the turbo. so either you replace turbos or you replace a sticking BOV.

Technology Posted December 10, 2010 Report Share Posted December 10, 2010 I got 16.5mpg on the highway last time I checked. I'm sure it's worse now, but alot of it has to do with how fast you go and how quickly you get to that speed. I can't drive...55. Dah dah dah dah, dananana, dah danananaaaaaa *air guitar*!

The stock fuel system turns off the injectors when you let go of the throttle at high rpm. The nose switch is partially responsible for that. When I shift at high rpm setting off my BOV my AFR goes full lean. Link to comment Share on other sites More sharing options...

Technology Posted December 10, 2010 Report Share Posted December 10, 2010 With a properly functioning everything, including nose switch, it should go vey lean if not air on engine decel above some certain rpm (I don't know what that rpm is).

StarquestRescue Posted December 10, 2010 Report Share Posted December 10, 2010 I ran a basically stock car with out one for many years. Same with my truck. Nothing bad ever happened. I would think mileage would be slightly better. But maybe not enough to really notice.Pretty sure the average stockesh car would run better with out all that air leaking in and out.
