I suppose what I'm looking for from him is what you just said... it will run rich, but it's not enough to matter.. I'm still curious if he's still using the electronic control system for them...

Don - some comments for your consideration - LONG - shortyq 2002-09-24 23:09:39 (1680 views)

Very interesting, as are your cars : ) - what's that smell?st 2002-09-25 10:08:32 (959 views)

Interesting info - thanks Scott. BTW I've been practicing my left foot braking. =) - markbradford 2002-09-25 07:16:49 (994 views)

Okay let's review: How much sheer abuse did BOV folks endure here before this? - sans-audi 2002-09-24 16:11:49 (1231 views)

A ton. Why? Because they were FULL OF CRAP. - nyet 2002-09-24 16:13:37 (1368 views)

Some people admitted it, in their defense : ) - what's that smell?st 2002-09-24 17:05:17 (794 views)

Well, yeah. - sans-audi 2002-09-24 16:18:08 (705 views)

Don what about "engine wash" - WJM 2002-09-24 14:52:35 (1368 views)

All cars are subject to the same emission standards, both high and low rpms - DonIstook 2002-09-24 19:30:47 (1048 views)

very true A/F ratios are what they are... - WJM 2002-09-25 12:28:38 (832 views)

Thanks Don! I still have a question about the design with a MAF though. - Joshua (wishbone) 2002-09-24 10:54:23 (984 views)

I think he is saying it only runs overly rich during idle (if the valve is misadusted and open) - nyet 2002-09-24 11:12:15 (931 views)

Naw, the car runs rich in essense because say for example you take your Forge valve - zapco98 2002-09-24 11:23:15 (1302 views)

ah got it. - nyet 2002-09-24 11:24:22 (651 views)

Don, can you confirm that these are the right ones? - DABearS4 2002-09-24 10:28:27 (1040 views)

Thanks for the info! Now my S4 will be perfect! - DABearS4 2002-09-24 10:25:35 (866 views)

what about metered air dumped between shifts? - BOOSTD 2002-09-24 09:39:49 (778 views)

I was wondering that too. Must run rich during shifts no? DOn, would you recommend this for...... - markbradford 2002-09-24 13:06:48 (873 views)

Well - I was thinking about this the other night - I don't think the ECU really knows what is coming - zapco98 2002-09-24 10:43:09 (846 views)

the mix getting to the O2 sensors is probably how it knows... - TRM @ velozt.com 2002-09-24 11:09:27 (838 views)

Does it matter how much is coming back?? - Joshua (wishbone) 2002-09-24 11:07:16 (737 views)

Right - but figure that if it goes back through the MAF, and say you're off throttle for a couple - zapco98 2002-09-24 11:13:39 (837 views)

Well... - Joshua (wishbone) 2002-09-24 12:38:34 (609 views)

[edit] but now the extra pressure in the INTAKE system will prevent MORE air from passing the MAF - nyet 2002-09-24 11:17:51 (722 views)

*and the whole S4 group moves to BOV's* ;) great info Don! - Audiboy 2002-09-24 08:51:28 (969 views)

;-) - TRM @ velozt.com 2002-09-24 08:59:59 (615 views)

Would this valve also work in the TT? Is all the information accurate also for the 1.8t? - Power5 2002-09-24 05:37:21 (835 views)

track this thread FOREVER! good stuff Don - thanks for sharing. - TRM @ velozt.com 2002-09-24 04:58:09 (575 views)

so can you tell us exactly how to setup the valve to keep it closed at idle? (amount of washers etc) - andre d 2002-09-24 02:27:36 (721 views)

Trial and error, but it is easy - DonIstook 2002-09-24 04:46:52 (839 views)

Did you use software to measure any particular value? What did you use to confirm that you had - what's that smell?st 2002-09-24 05:50:04 (710 views)

The software was my finger on the valve to feel if it opened or not at idle. - DonIstook 2002-09-24 05:56:41 (834 views)

Cool, thanks. - what's that smell?st 2002-09-24 05:57:27 (666 views)

Yeah, that would be my next question also. - what's that smell?st 2002-09-24 04:17:03 (599 views)

Hi, so basically any BOV would work on 1.8T as long as I get the adapter kit from Turboxs? Thanks. - Jack Wang 2002-09-23 22:44:28 (1130 views)

no meng.... - wnut 2002-09-24 09:53:19 (899 views)

Oh, Ok, so for 1.8T the BOV will be where the BPV is..am I thinking right? - Jack Wang 2002-09-24 11:49:08 (1869 views)

there's about 3 ways to mount a bov on a 1.8t - wnut 2002-09-24 12:12:22 (1246 views)

Is there much to do with the H valve to install it? Or is it just "plug and play"? - naptownnogaro 2002-09-23 22:16:47 (839 views)

iirc they're about $150 a piece... - wnut 2002-09-23 22:20:53 (1180 views)

this is what i've been saying all along... - wnut 2002-09-23 21:53:58 (1019 views)

Saw this on rookie Edwards car . . . look a mechanical throttle valve . . . . ! - boscoj 2002-09-23 21:11:56 (1534 views)

i'm 99% sure that it's a forge bov. - wnut 2002-09-23 22:29:32 (1705 views)

You can barely see the pop off valve on Galati's and Bell's car in this pic - boscoj 2002-09-23 22:38:57 (1755 views)

Yup, they have a single BOV (which Subaru folks use) - Audiboy 2002-09-24 08:54:07 (826 views)

by jove I've think you've got something . . . - boscoj 2002-09-23 22:36:56 (716 views)

This is the one that I found on the site is this the right one??? - FAS4T 2002-09-23 20:53:09 (1915 views)

that bov is crazy loud! - wnut 2002-09-23 22:31:39 (1415 views)

As Stealth4 says-I think he means this one. You're going to order two of them tomorrow, aren't you? - gr 2002-09-23 21:06:32 (911 views)

I could buy them right now, tempting! but what about the mounting hdwe? - FAS4T 2002-09-23 21:12:32 (920 views)

I think its the regular H one, unless ur making ajoke - Stealth4 2002-09-23 20:54:50 (657 views)

no really I think I may be blind this is the only one with an H that I found on the site.... - FAS4T 2002-09-23 21:06:48 (891 views)

http://www.turboxs.com/ - DonIstook 2002-09-23 20:17:28 (1937 views)

How about the mounting hardware? Is it the same as they have for the "1.8T?" - zapco98 2002-09-23 20:30:41 (790 views)

you are awesome, thanks for the real life tested info. - Stealth4 2002-09-23 20:12:58 (789 views)

hey, you said a "little tip" - Odorless-Clandestine 2002-09-23 20:10:59 (918 views)

Well, the tip itself is small, but it took a while to get there - DonIstook 2002-09-23 20:16:02 (1072 views)

Well, it's tremendous to see someone take the time to post up such concise and useful info (truly). - Odorless-Clandestine 2002-09-23 20:21:47 (911 views)
