I have one and love it! Very Very loud :evil: I think I paid about 160 for mine so I would say that is a good price.

Not to highjack the thread, but where can one buy a flange for this BOV. I bought a used one and it didn't come with the flange. . .

I have an amunium flange you can have...
However I found the cost of welding the flange on was the same price or more then buying a pipe with flange off Ebay.

I like my RFL but I wish it was Louder :)

I've got the TurboXS type H and i love it, it sounds awsome. Its almost the same as the RFL, just doesnt have that cone shape on it.

So I'm looking at about $176 for the BOV and flange pipe? :(

Look up BOV and you'll find a dual horn RFL, it's not a turbo XS one but it's a little bit louder and quite a bit cheaper. probably be 70-80 dollars for the BOV and flange pipe after all is said and done

40 bucks for the valve and I think the weld on adapter(Im using exhaust pipe for the intercooler pipes) so thats a great deal how does it hold up.

As far as quality aftermarket BOVs go, the RFL is probably one of the cheapest around. I have heard a lot of people doing well with them.

I have a Garrett TiAl on my GTS, and it ran me right around $240 after shipping, just to keep the price on the RFL in perspective.

I bought the K&N that FWD-P sells for $35

Got Midas to give me some 2.5 and 2.25 inch pipe, and weld my flange on for free. (I have connections.:eyebrows: )

Total cost of my BOV project was around $270, but it was worth it from my point of view.:D

You mean the TiAL 50mm valve? If so, TiAL has zero affiliation with Garrett/Honeywell, just to clarify for you.

I had no idea, from all of the companies that carry the valve they made no indication that the valve was made by Garrett .
It came in a box that said "Garrett Turbochargers"
It is also pictured and listed on turbobygarrett.com:

It looks as though Garrett is simply carrying the TiAL product now, interesting.

From the website... "This custom TiAl manufactured Blow-Off Valves," so they at least state they are manufactured by TiAL. No matter really, just wanted to make sure you didn't pay the price for a real TiAL valve and get some imposter off of ebay claiming that it's a "Garrett Tial!" Ya know?

Yeah, I was in disbelief when I saw the box!:) I threw it in the closet because it had a pretty cool design. I guess it is probably a generic Garrett box, and they just packaged the TiAl in it. There are stickers that idenfity the fact that there's a BOV in it, probably just a generic box then.:nod:

Well, now that we have that settled, back to topic.:D

I had the TurboXS RFL on my car(s) for a while. It always functioned perfectly and I never had to add the washer/shims even running 18 psi with it. I liked it although I'm the kind of person who likes loud BOVs. For ~$149 I think it's a good BOV to get.

I'm now using the ATP RS BOV on two of my cars. The sound is very similar to the RFL. They both use large air horns on the discharge and both were about as loud as each other but the RFL still sounded a bit better IMO. The versatility of the ATP RS BOV can't be beat though.

Ground Rat
03-02-2006, 07:13 PM
Well I bought the cheap RFL knockoff off ebay, less than $40 shipped! I hope it works fine; I'm only at 12psi. Now I'll just have to find the right size pipe to mount the BOV on and weld it to my IC pipe.

My BOV got here today, just need to install it now. It comes with a bunch of washers. How do I know if I need them? What are they for?

Garret
03-05-2006, 01:36 AM
If you twist on the cap where the nipple is it will come apart and you can shim the spring with the washers, you won't need to use any of the washers now but save them just in case

What is wrong with it?

Ground Rat
03-06-2006, 10:22 PM
I think there must be a vacuum leak; the BOV won't open and the air pressure is going back out my intake. I took the BOV apart and the valve moves up and down fine so I doubt that's a problem. I am still hitting 12psi when I drive my van so it must not be leaking around the flange. Maybe I should JB weld the vacuum nipple to the top of the BOV?

If the nipple threads in fine then don't JB weld it, that'd just be stupid.

What are you using as a vac/boost source?

Right now I'm using the nipple off my TB. I also tried disconnecting my boost gauge and using that one for the BOV, but nothing. Those two vacuum sources are really the same though. Here is the BOV I have:

BTW, I'm not using any shims (washers).

03-06-2006, 11:09 PM
You might want to try a better vac source. I have read differing accounts of using the TB nipples. Seems like they are hit or miss.

Garret
03-07-2006, 01:28 AM
Yeah that's your problem you have it hooked to the wrong nipple on your TB, use a different vacuum source :)

Ground Rat
03-07-2006, 02:37 AM
Hey guys, I just disconnected the line from the TB, plugged it off and tried my boost gauge vacuum source again. It is getting vacuum directly from the manifold right above the fuel rail. The BOV still does not work. I'm thinking there has to be a leak somewhere; do you think that makes sense?

BTW, my TB has two nipples and says Holley on it. Is this an aftermarket TB?

Garret
03-07-2006, 02:40 AM
Nope that's a stock TB. Hmmm, next thing you need to try is just sucking on the nipple LOL to see if the piston is moving up or if it's just leaking if it's just leaking, you might need to seal up the threads on the nipple with teflon tape, I run that same BOV and it worked just fine outta the box

OK, I guess I'll bust out the teflon tape then. I suck on the nipple as hard as I can but nothing happens. :o

Garret
03-07-2006, 12:26 PM
yeah it should've moved just a bit so it's probably leaking out of the threads

With the engine running and vacuum applied to the top port, the piston should be closed, but easily open if you reach through the horn and push on the piston with your fingers.

use the brake booster as a vac source...much better.
Also since is a cheap knock off perhase the piston is not sealing properly..i'd try greasing it abit to help seal.

You win!!!1 lol I hooked it up to my brake booster and now it works (and sounds awesome).

There is a new problem though. The thing starts to open at about 5psi; I can hear it leaking. I tried puting in the shims that came with the kit and they only seem to control how long the valve stays open. Even with all five shims (washers) in there, it would still start to leak around 5psi. The only noticable difference was the valve closed quicker. If I put a g-valve between the brake booster vacuum source and the BOV nipple to adjust the amount of vacuum seen at the BOV, do you think this would help?

Thanks a lot for your help so far guys. I can't wait to get this working 100%. :nod:

Garret
03-07-2006, 10:39 PM
is it 5psi while driving, or 5psi while in neutral?

While driving. I don't think can I get 5psi while in neutral.

Garret
03-07-2006, 11:05 PM
Hmmm, my only question then is the valve you hooked it up too a check valve that doesn't see boost? because if it's hooked up the brake booster there should be a check valve preventing boost from going in. Because there should be the same amount of boost pushing the valve closed

CanadianDaytona
03-07-2006, 11:32 PM
No check valve on brake booster, thats how mine is hooked up (however mines a real RFL)
with 5 shims in there it should not be blowing off at all really

Here are a couple of pics. I was hooked into where I normally get vacuum for my boost gauge in these pics.

thats going to make it worse it just needs some good vac to the top of it,listen close ly to it while theres vac on it and see if you can hear it leak around the piston.

The stiffer spring should stop it from leaking, but I agree that it is an issue of not getting proper vac.

hooked mine up a little bit ago I had a turbo xs type s and there was a little surging due to the valve being to small. I used the vacume fitting on the top of the TB then only thing that is different on my set up is that I have a brass fiting on the BOV were the nipple was that is for a -4 an fitting and I have a old stainles braided line I just cut one end off of with a grinder and slid on the vac nipple on the TB and held it with a clamp this was the same thing I used on my type s due to the vacume line colapsing from time to time. I didnt get tto take it out of the garage tonight or off the jack stands cause it is in the prosess of being painted and there is a omni broke down in the drive way so I just got to rev it once or twice and it didnt sounds to bad.
