Jim Green's 90q 20vt - 636whp 07k

None of the 7A heads I have, nor the 3B head has the breather nipple. Interesting...

As you can see, I've found a need for lots of breathing out of the valve cover, a dash 6 and -10, -6 goes down to the block outlet, -10 straight to the breather can:

The 7A isn't even supposed to have the nipple, but some of the heads do, and it's capped. I had to go under the 3B slides to even find the part number for the rubber cap when it started leaking and caused a major warm/hot idle problem (car would stall). The AAN slide doesn't list even the nipple (on the 3B and 7A, it is actually removable) or a cap that I could see. Also looked at the vacuum system slides for the 3B, doesn't show anything connecting to the nipple on the valve cover.

So.....?

I've never seen a 7a valve cover with a nipple, and never seen a 3B/AAN w/o a breather nipple, not sure about what ETKA has to say about it, but in the US, what you're descirbing is extremely rare, and all I5 turbos have come with ventilation to the valve cover. Only the NG and 7A come to mind that don't have venting in the valve cover.

Anyway, great job JIM! :woowoo:

Well, the one I had has the nipple...It is now residing in Jonathan's shop on his 20v motor, I have his 3B cover. The "slides" I was referring to was actually ETKA, US version current to MY2003 cars, the ABY/AAN slides clearly show the breather hooked into the cover, but the 3B slides do not. The cap is an 8mm item with an AL12-22 clamp, found under the 1991 200q20v (US and Euro) and the 1991 urq (RR engine), the S2-3B does not list the cap but rather the breather setup.

You can see it in this picture:

And even better in this one (see attachement).

I have the car running at about 13 lbs of boost and I can't get used to how it just keeps building power! This is too freaken cool. It hit 18 psi last night when I had the wg cranked down a little too much and I was getting torque steer like I did on the 20v with race gas in it. I can't amagine what it's going to be like with the WI hooked up and close to 30 psi of boost. :woowoo:

so that's how you break an engine in?

audifreakjim · Post by **audifreakjim** » Fri Jan 13, 2006 8:52 am

Yep, brought it up to temp, let the fan kick on 3 or 4 times then let it sit overnight. Next day, changed oil filters, re-torqued the headstuds, and commenced flogging. The 18 psi was a little much for now. I think I'll leave it at 13-14 psi for the next 500 miles.

It's nice at this level, there's no surge in the turbo. I can stomp on it in 5th and the car accelerates really well even at 3500 rpms.

Sounds good to me! I'm not a fan of babying a new engine, you gotta "break" that sucker in.

this isnt an issue with the 4 cyl blocks is it?

audifreakjim · Post by **audifreakjim** » Fri Jan 13, 2006 9:17 am

I doubt it, but I should have known better when installing the studs. I noticed that this stud was higher than the others. I pulled it out and looked in the hole and saw metal at the bottom. I never thought to look on the side of the block and see what was screwed in right there. So the moral of the story is if there are holes tapped into oil or coolant galleys proceed with caution. :wink:

One more thing I didn't mention, I'm running a new 4 bar MAP sensor that Javad offers. Now I can see all that boost, and the car runs great down low too :-)

olsonjus · Post by **olsonjus** » Fri Jan 13, 2006 9:37 am

So only 1 map sensor? Sounds like a really fun car. I need to get off my ass and finish my car. The money tree has been hit really hard in the last few months. Once it recovers I'll be building up the motor.

Regards,
Justin

Yep, we update the internal map sensor inside the ECU to 4BAR, and it still reads down to 20kpa like the 2.5 BAR sensor 8)

Audilard · Post by **Audilard** » Fri Jan 13, 2006 10:00 am

So it's an internal 4BAR senson now. Am I confused in thinking you only offered the external unit...or am I just retarded.

Yes, you are confused, doubtful you're retarded

We are going to release this as a new option/feature coming soon, Jim was Beta testing it and clearly its working fine, no bugs etc.

Look for a more official release about this coming soon, and hopefully less confusion :-)

I'm a little confused too... seems like 2-3 months ago you were 'splaining that we had to give up resolution in the fuel/spark maps off boost/down low in order to get control above 2.5 bar...

Is the upgrade all software or harware software...???

glückliches Fahren to you Jim... kudos for getting a super conversion done fast and back on the road...

Whew! Glad I'm not retarded. I'll keep my eyes open for this, and try to read more carefully.

Doug, like Nate says, this is a NEW product offering.

More info coming soon. 8)

AAahhhh, this is what confused me....I knew there was something out there.

Of course, we still have that too, and that doesn't require sending the ECU back, but like I said, more info soon

do you guys have quite a bit of blow by, more than most cars?

Why would "we"? :?

My 80tq motor, after all this time and running over 38psi boost, has less than 5% in 3 cyls, 8 in one, and 10 in the 5th, completely acceptable and low for what this motor does and has been through.

pkw · Post by **pkw** » Fri Jan 13, 2006 12:14 pm

shrug. just wondering because of the added venting in the cam covers you guys are doing. must need more than the usual vent in the block? with the stock set-up as you know, if you try to take a peek, through the oil fill etc, the engine dies. figured audis might all have a lot of blow-by and many would never be able to see it. wanted your .02

The reason the engine dies is due to the fact that you're bypassing air around the MAF into the motor, as you likely know, has nothing to do with blowby. The main reason why Audi routes the crankcase back into the motor is emissions related, the rings seal fine w/o vacuum, and yes, there is an awful lot of air coming out of the crank case when you're making 800HP, as Nate's emperical formula proves 8)

Its the better of 2 evils, Satan being sending oil back into your combustion chamber.

Hmm, by my super rudamentary logic 5+5+5+8+10/5=6.6% blowby X say 750bhp=49.5hp worth of gases coming out the breather system. The gas flow numbers get pretty crazy at the insano HP levels

Maybe Javad can call his Speed Channel connections and get Jim an all expense paid trip to Toronto to get the Ginster Monster on that dyno segment of Sports Car Revolution with the ultra-hot blonde???

I know it would fit my definition of good TV!
