******* wrap a sock around it. You don't even need to waste a zip tie; just knot the sock up on it.

Looks like a diverter valve, but its adjustable.
Has 3 different rate springs.
Just looked on their site and couldn't find the exact same one.
I'm sure you can find one used for a decent deal.


The ONLY other bov that I love (and would run on my car if given the chance) is the TiAL....

Regardless of the internet online arguments, I like that engine bay.

I dig the black compressor, the silver blades stand out!

Thanx
I added a black intake+gray filter to it now cause I can't be driving around with no filter for ever.

Thats the once I have. It sounds more like a woosh, with a faint pshh. I hate the squealing of the hks type ones, so thats part of the reason I like it.

Second reason is that they are built great. I took mine apart to check it, and the piston / o ring / machine quality is exceptional. Easy to overhaul, and it seals 1000x better than the ebay one I had before.

Also, they sell a spring kit, so you can fine tune it for your boost levels / car.

They usually don't leak much, thats what the spring is for. That doesn't matter anyway, you are running an adaptronic (which I assume you are using a MAP sensor with). So it won't mess with your ECU at all if it leaks a little at idle.

Well i just got my bov. Now i get how it works. There is the regular piston controlled by the vacuum thats outside, there is also another piston inside the big piston. The outside piston is like a master of the gates. When its closed, both are closed. When its open the inside one still remains closed. The outside one is the one with a lot of force on it and thats controlled by the vacuum. The inside piston has little force just enough to keep it closed when the outside piston is open. During regular vacuum operation, the outside piston is open, the inside is closed. When you spool that turbo up, and let go of the gas, the vacuum pulls the outside open, the inside is then pushed back by the pressure build up inside the pipes forcing it open. The real question is how much pressure is required to push the inside piston open or will i still be surging if i dont step on it?

At least 3000000 pounds of cake are required for fullfillment of such exhibitory feline activities. Such soup is often a pain in the ***; remember to put lids on it!

Mine sounds exactly the same and I hate the little chirp. I have it re-routed which seems to have gotten rid of the chirp. I'd rather just vent it in order to have less piping, but that damn whistle is so ghey

cant you add 2-3 inches of hose to the end of it and still vent it? That should get rid of the whistle. From what i can think of the whistle is caused by the air hitting the outside edge of the horn. Also isnt that bov open in vacuum as its made to recirculate?

I have this one, and it sounds like...


Oh and chicks dig straight-cut gears, with a stock exhaust.

What the hell happened to the quality of my video? It's been on youtube a long time, but has never been that crappy looking!
