Question Recirculating the HKS SSQV BOV

Hey guys,

I'm installing an HKS SSQV blow-off valve and I want to recirculate it, but I'm kind of stumped on the installation. I have the recirculation fitting, but the kit doesn't come with the pipe/hose to go from the BOV to the intake, so I'm left to purchase or fabricate one. If I mount the BOV in the way the instructions say - right next to the fuse box - recirculating it will be a pain in the ass because of the angle and distance from the front of the BOV to the intake. I could use the stock hose that holds the bypass valve to mount the BOV lower, but then I'm not sure if there is enough room down there for everything.

I know a lot of people recirculate these things. Can someone who has pulled it off give me some pointers, or better yet, some pics of the installation?

Thanks!

EDIT: Oh also, how did you overcome the problem of the BOV recirculation adapter being 1" (outside diameter) to the intake's 1.25" (inside diameter)?

Awesome, thanks! I see that you mounted the BOV backwards in order to make the piping work. That's a good idea. I'm really curious as to what piping you used, specifically, and how it's routed down there. I hope it's not something like this?

Regardless, I look forward to seeing the pics. Thanks dude!

No its not like that! haha. Luckily I had all my intake components out (because Im doing the 60K tune up). Yea, I was in the same boat as u. I searched everywhere to find how to make it work and ended up just taking a stab at it and it turned out really nice.


Here is the overall setup:

The MAF slides right over the piping.

Here are some other close up shots of my setup:



I used a small plumbing fitting to connect to the bubble section because of the 90 degree turn it needs to make. (Most of the stuff you need will be in the plumbing section).




Hopefully your kit came with one hose. If not you can just get extra to fit what you need.
I cant remember the exact size of the hose piping I got. Just take your BOV to loews with you and find something that fits snug. You dont want vac leaks.

Hope that helps! Good luck

Hmm, interesting. What's the black wrap you have around the ends? And tell me more about the pipes... where did you use the one that comes with the kit, and what is the original purpose of the ones that you got from Lowes? I'll swing by there or Home Depot after work tomorrow with BOV-in-hand, but more information can never hurt

Thanks, I appreciate the help!

I was looking at radiator hoses, for sure, but I couldn't decide which shape to get. You can't really bend them too much and they come in pre-bent shapes, so I would need to get just the right part. Now that I've thought about it some more, though, I don't think the output pipe of the BOV needs to be anything hardcore. Mainly it needs to be able to withstand heat and tough enough to not break when I tighten it down on its ends. It doesn't need to withstand much pressure since all it's doing is venting pressurized air back into an unpressurized intake. It does need to be solid enough to not collapse on itself when the engine creates a vacuum in the intake, though.

Inflam, is that vacuum hose wrapped in a heat shielding tape that your BOV sits on top of? It kinds of looks like that way from the pictures.

Thanks guys, I'll get this figured out one way or another

Yea I just some heat wrap to make sure it was secure and had no vacuum leaks as well.

Im pretty sure this is the kind of stuff I used:
Polyethylene Tubing

I cant remember the exact size. (maybe 1 in.? or 1.25 in? dont take my word)

The one hose right below the BOV right here Im pretty sure the stock BOV hose.


I added some tubing to it to elongate it up to the y-pipe.


Here I used the extra piping to connect to the other side of the BOV with the bubble part. They have vacuum fittings that make a 90 degree to connect to the tubing.

hey guys,

I'm looking for some help. I have a 1996 Mitsubishi VR-4. I had a blitz blowoff valve. The way I had installed it was hitting the shifting arm and was damaged. I replaced it with with HKS and did something like the pictures show to get it to recirculate. The problem is after the car warms up it won't shift or go in gear. It,s never done this before until I put on the new valve. if I put back on the old one and it works fine. Any ideas?
