Wow, those are pretty neat. Not a lot of info on their site though.

Damn i wish we could do Youtube at work.

Found a few discussions on them, and the youtube video on this first one worked at work. I dont' know how.

Anyways, the set screws I don't like, and the action of it moving, while it looks cool, could be dangerous in the engine bay.

Think about it a bit.

Hah!

OBX has already struck.

The MFR's actually post here.

 

bah and more bah.

Seems to risky to not just use a coupler and adapter and KNOW that it will seal. Rather than rely on an o-ring and some set screws.

I like the theory...just too many flaws

 

True. I mean O Rings on the space shuttle failed, these could too.

LOL

I'm kinda suprised they made it like this and not something you just put a couple of couplers on.

 

I think some of your are lacking in your engineering competencies tongue.gif O-rings have been used to seal pipes/nipples what ever since the day of time and are quite successful at doing so. Example, quick disconnect fittings on compressor airlines use o rings in the female base to seal around the male nipple that is pushed and locked it. I run my industrial compressor at 175 psi for my sandblaster that has quick connects on the inlet hose. They never leak unless worn out from too much use. Anyone here running 175 psi of boost? These are rated for 200psi.

The key element in sealing is the OD of the pipe must be in tight tolerances with the seal of the BOV or else it wont seal worth a damn. That tolerance is what will make the difference between a GOOD seal like quick disconnect fittings or vacuum leaks out the wazoo. Secondly, the possible damage of the o-ring from installing/reinstalling, environmental elements, heat, chemicals, etc. Hopefully, they have replacement o-ring kits laugh.gif

 

Yeah but how perfect are the ends on charge pipes? rarely ever perfectly round. to each his own.

Good point tho tanc

 

Looks cool, I also dont like the set screws...

Why couldent they just make the ends longer and fit regular couplers over it...???

 

I'd prefer just to weld mine in. No o-rings, no set screws, no hassle. I guess there method for set screws is that it easily removable. The o-ring really locks the pipe in, all the set screw does it hold the pipe there as a backup. Myself personally, wouldn't like searching for tiny set screws under near the pipe to take the bov off but this way does provide only 2 spots for leaks rather than 4 with couplers. My weld in method has 0 spots for leaks however tongue.gif
