They are shipping the kits with this adjustable black one. Any better than the old silver plastic valve?

 

Ed, did you get an answer about the correct orientation of the valve?

I figure that the butterfly only swings one way to open (clockwise I believe-but i didn't crawl under the car to verify), therefore, in the orientation i have in pic below, the valve will slam shut under boost-if it was turned around the valve would be forced open by boost and unecessarily recirculate the charge air.

At idle, vacum would hold the valve open (no matter which way it was positioned, you would only really have a problem under boost)

 

That one looks alot better then the POS they sent with mine when i had my kit....

I have not ask about it. I can't see it being a problem either way. But what do I know.

I'll fire off an email to EPP and see what they say.

The valve does look nicer than mine. Its only $47, so debating on changing it.

 

As per the instruction manual:

Either way, the valve should block flow. However, you'll note that the actual butterfly is offset in the housing. I'd probably put the "shorter end" on the intercooler/pressure side, so that the butterfly bolts are on the backside of the valve (in relation to air flow). I hope I didn't say that backwards.


I was somewhat curious -- this is my first blower (twin intercooled D1sc). How 'leaky' should that surge valve be? Even with the butterfly closed, I can easily blow thru the housing -- seems that it would bleed off a lot of pressure. Perhaps the butterfly just needs readjusted...

 

Anything is better than the old silver style one. That thing leaks like no other.

 

You might want to check that price....I'm pretty sure it's more like $147.

 

Double checked my PM $47. Going to order it tomorrow

 

Well, good luck getting it at that price-I ordered one a couple months ago and it was about $100 more than that. Whoever you're getting it through is loosing a bunch of money!

 

Just ordered it for $47 :dunno:

 

You may want to make sure you ordered the 'ProFlow' valve. That is the one that comes with most kits, but they do have the 'Standard' valve, which is a small plastic Bosch valve-by that price, I would assume you ordered that one.

 

I ordered the one in the above pics.

 

Cool Ed ! See, it was worth helping me so you got a good look at the new BPV !


...and nobody has commented on my busted-*** swaybar mount ! (It's been fixed since the pic was taken).

BTW, car is running great. I was throwing P0101 (MAf freq) the last few days but after some research I made some small adjustments to the low RPM/idle VE and it's much better cold starts and no more bucking at all during low RPM low load situations (which was when the P0101 was getting thrown).

No codes on the way to work this morning or during the lunchtime drive !

Oh, and got the McMaster Carr check valve installed too. So far no problems.

Cheers !

Who did you order from? I want one too!!!

 

Hmm.... would have been worth it if you bought it for me :p

Glad the install is holding. *knocking wood*

My heads should be ready today, and if they are. I am going to try to install them this weekend. :woot:

 

Bob from EPP

 

Woowoo ! Let me know maybe I can come lend a hand ! Let's do mine next !!

Rob (Bad30th)

 

Yep got them!

I think I will start on the install tonight.

 

For $47, I'd be willing to bet Bob misunderstood what you were asking for and gave you the price of a Bosch bypass valve. It looks like there is a fair amount of machining time and assembly time into that new ProFlo bypass valve. Bob is a hell of a guy, but I doubt he'd be willing to sell a $150 part for $47. Just my .02

 

I see the Fry's ad wasn't too far away
