just wanted to know which BOV are 100% recir. this damn RFL sux cause it makes my car bog out badly!!! thanks for the info!

 

I don't think that the bov would cause it to "bog" down. You run rich between shifts, but not THAT much to cause you to stutter like that (if it's as bad as you make it sound).

Many bov manufacturers have recirc. kits you can purchace.

 

running an open ATM BOV set as closed as possible (adjusted as far down as it goes) caused my car to bog when the turbo would attempt to build boost while my throttle plate was still partially closed. thus, pressure in the IC would force the BOV open, and release some air under part throttle at high RPMs. made the car bog and stuter badly. not a lot of fun when autocrossing or even just trying to run a steady speed at high RPMs driving at all.

 

I know the bosche bov or diverter valves are true recir. Vw uses them on all their turbo cars. The only problem is that they feed hot air back into your intake before your turbo. Also forge makes a direct replacement for the little pieces of plastic crap (oem on vw break easily and often).

 

its doing that because of the maf sensor. if you want a good bov for cheap try a first gen dsm bov and recirculate back to the intake. but ive seen people run them out to the atmosphere. i really dont understand how thats possible and have the car run right.

 

yeah i do know that it is becuase of the maf sensor...however i dont want a peice of plastic doing my blowing off...my two friends with there evo 8's have gone through 2 stock BOV a peice...need soemthing that isnt gonna break easily, thanks for the info tho'

 

the forge replacements are metal and handle inceased boost pressures

 

the first gen dsm bov is an aluminum piece and can be had for about 40-50 dollars with a flange. if you crush the top in its good up to about 14 psi.

 

why was my post deleted

 

On my 1992 eclipse gsx i hit a 13.0 @105mph on a stock bov at about 21 psi before i swapped it out. It worked well. another good one is the greddy type s because you can recurculate it.

 

don't use a 2nd gen dsm bov because they are junk. they are made out of plastic!! if you wan't a 1st gen bov i still have mine if you want to buy it.
