BOV trouble

[evanisonfire]

just got my turbolife FMIC today and my TurboXS type-H. i tried to hook up the BOV to the stock intercooler just to see how it sounds. and it didnt make a sound.... it expelled the air and thats it.. i tried adjusting it with the washers and still nothin... no sound. here is a pic of what i did

i just took out the BPV and put the BOV there and plugged the whole where in the intake. maybe i hooked it up wrong??

You cant hook it up like that, because where it needs to be a recirculate back into the turbo. Have you try driving it? the car will stall out because the air is not reading right. you might have to relocate your MAF.

well ya i have the turbolife FMIC i jsut got in today. so i will be relocating the MAF on the coldpipe. but i jsut hooked up the BOV to my stock intercooler just so i know what it sounds like.. but it didnt make any sounds.. it would open and release air but it wouldnt make a loud blowoff sound. i know i cant drive the car like that i just set it up temporarily to hear it. so i dont know whats going on. unless it will sound good with the right settup??

whats the point if you're going to be putting the rest of the piping in? JW

Were you actually driving or just sitting there revving the engine? You're not going to build enough positive pressure sitting there in neutral to warrant a decent blow-off.

Also be warned, I could not get ANY TurboXS BOV's (Type H and Type H-RFL) to work with my turbolife kit with a relocated MAF. They all leaked and caused system too lean CELs. Hopefully this isn't the case for you, but for me TurboXS BOVs are crap.

oh really? is there not guys on here that have made them work i thought? also (i dont know if it matters) but did u weld on the flange? and yes i was parked and reving it but normally even that gives a loud enough blow off the head through the hood.. especially if its supposed to be RFL.

I made a custom cold pipe with my kit because I needed the bends to be in different locations. I had a shop do all the welding (this includes the BOV flange) and I used the supplied aluminum flange I received from TurboXS. At first I had the Type H and for the most part the car ran just fine. However, while idling at stoplights or whatever, about every minute or so the car would stumble, my wideband would go lean for a second, then catch itself and be fine. After doing this maybe, 3 times the CEL came back on and I wasn't even home from the shop yet. Because the only thing that changes was the BPV, I decided to pressure test it and sure enough, it wouldn't hold vacuum. I chalked this up as a defect and returned the Type H and got a Type H-RFL in return. This one I didn't even install and tested it right there on my desk. Surprise, surprise it wouldn't hold vacuum either. So I called TurboXS to inquire about this and all they kept saying was "add more washers". When I finally got them to listen about the vacuum issue they responded by saying it was normal because it is a metal-on-metal seal so some leaking is to be expected. Well because of this, I knew their BOVs would never work on my car because the vac line to BOV was pulling extra air, bypassing the MAF and placing it into the intake manifold. After that I got an HKS and everything has been fine since that day.

As for revving it in neutral - I can't even build positive pressure in neutral so I have no idea how you expect to hear anything. Even with my HKS I get a barely audible "whoosh" sound. I have to be in the 5+ psi range to get a good chirp.

yikes... well thats not good news for me i dont really want to weld on the flange if the BOV wont hold pressure. i may just create a custome rubber seal to stop the leakage. think that may work?
