i have a redtop sr20 and im using a greddy bov (not sure thos bought it with the car). Here is the thing tho im hearing that some B.O.V’s dont work well with some motors so i need to know if this is true and if so, what do u guys recomend? I need one asap.
What are u guys using?? I have heard hks is really good
Non recirculated BOVs (ie atmosphere) can cause stumbles with MAF equipped cars. Most of the time a bit of adjustment can take care of it. If you run it too soft (blows off all the time) you’ll notice when decelerating sometimes the idle will drop or the motor will stumble.
Recirculated BOVs won’t have this problem, but they won’t have the loud PSSHHH sound.
yeah, make sure your BOV sounds how it’s suppose too.
not sure about the type r, but the s is a very high pitched knife edge sound, the RS is a WOOOOSH sound.
if you’re hearing something that sounds like a turkey or a fluttering, then your BOV is crap.
one way of checking if it’s a knock off or not is that on the body of the BOV (close to the flange) you will see a small plate piece sticking out, if it’s a reall greddy it will have ‘greddy’ etched into it, if it’s a knock off, it’ll just be blank.
in that case, you need to get a properly working BOV, and if you go HKS, remember, you’ll have to buy an HKS flange and have someone weld it on.
but then again, I’ve heard with a little hacking that the hks/greddy flanges can interchangeable.
yeah i have the same problem when i let go of the throttle. The car will sometimes stall. I have the greddy bov but not sure if its the rs or r but it’s adjustable. The problem is i don’t hear it at all so i don’t think it’s set to soft… What could have cause this problem?
FYI…mine is recirculating, i would not use a dump type in a MAF system (as i dont care about noises ect…)…and make sure the recirculating is after the MAFS…cause that air is already metered for
