someone over on LISC.com said that the RFL bov was crap and that they needed 6 washers to close the valve at idle, but then it was too tight and caused turbo surge... but i run a stock wrx... anyone wanna shed some knowledge on the RFL on a stock WRX? good bad? any opinions on the greddy type s without recirc?

See, the thing most people are missing, is that whether the valve vents to atmosphere or recirculates, that air is not going into the intake anyways. Yes, in the case of a recirculating valve, the air is still in the intake tract somewhere, but this is not a large amount of air, nor does it happen over the course of several seconds. If that was the case, yes, it probably would make it run rich. But, it happens for a split second and it is a very small amount of air. And, the valve opens when you let off the throttle, which tells the ECU to cut the fuel anyways. So, no, they don't make any car I've ever had a wideband on run rich. I don't claim to know how they work on an Eclipse, or on a Supra, or any other turbocharged car, but on a WRX, they do not. Period.

If I get a RFL from turboxs, does it come with a plug for the inlet pipe? How much do they run for if they are sold seperately?

arent RSX's MAP based, and there for dont meter the air comming into the system but instead measure the pressure in the manifold?

If you get the WRX kit, it comes with the plug and adapter plate. If you buy just the BOV, that's all you get.

Rich Conditions

I just put the type-h on mine, it did run rich at first but that was due to the BOV not being tuned right, i had to throw a couple of washers in there to tighten the spring up and it now idles perfect, never drops real low and back up.. Now for other cars, my 2g eclipse I just sold for my WRX it did how ever run rich and die a lot from venting to the atmosphere... to kinda answer 2 posting questions I had the greddy type-s on there and it sounded good venting to atmosphere it is loud and sounds good, but on eclipses the air is metered by the maf and when the air is dumped back into the tract there is fuel to compensate for the amount of air that is suppose to be dumped back into the tubing... So as long as the BOV is tuned right your WRX should not be running rich and stalling.

Talking

The HKS is good. I have it on my wrx and it sounds great. Running full boost it is load as hell. HKS sells a recirculating piece for 12 bucks on there website that attaches to the BOV. And about the backfires, it's from no cats. I have none and it pops and farts all the time.

Actually, yes, they do. Three of the ones around here have gone bad. Mine included. Everything wears out. If you are running much more boost than stock, expect to get about a year out of an HKS BOV...

Are there ways to "rebuild" it, or is it basically a fancy paper weight when it goes bad?

I haven't heard of anyone rebuilding it, but I'm sure you can. Most people just buy a new one.

I finally got my BOV installed lastnight (among many other things.) All around i would have to say that i like the TXS RFL BOV. Its loud and doesnt sputter out like the TXS type-h. I also like the sound of this one over the HKS its not a high pitched. One thing i havent decided if i like yet or not is that it blows off realy loud even at only 3000 rpm... Over all im happy.
