<center><img src="http://pictureposter.audiworld.com/AudiWorldPics/2000/Mvc-699f.jpg"></center><p>Here is the aluminum throttle body. Louis Milone fabricated this piece. We installed Turbonetics 2 1/4" to 2" adapter hoses and I fabricated the aluminum tubing from the intercoolers to the throttle body. The intercoolers have an outlet of 2 1/2" so I used a Turbonetic hose to reduce the size down to the 2 1/4" aluminum tubing. I used "U" bends and cut off the angles that I needed to produce the bends in the tubing. In the picture, you see the stock Bosch blowoff valve. We initially used Turbonetic aluminum valves, but the rubber gasket inside would blow apart too easily. The factory part has a steel plate inside...the same as the 993 turbo...and they are pretty good.

Don are the A4 OEM valve and S4 the same?

I'm just asking because there is alot of us upgrading with new valves, and we're obviousley running alot less power than you.

Thanks

00'1.8T + $$$'s of other stuff

also why did you reverse the postion of the valves

any reason other than the boost pipes are so Friggin' huge?!? ;P

I'll be gone until Saturday FYI though

I run them that way so that the hotter pressure gasses coming off of the intercoolers will hit the metal part of the valve instead of heating up the rubber gasket first. I bought the aluminum valves from Turbonetics, but I don't think that they make them. the rubber gasket inside of them is flimsier than the factory Bosch part......actually, the Bosch part is pretty good....it is also used on the 944Turbo and the 993 turbo

I will try to look on the microfiche tomorrow and let you know.

Part # 034 145 710a

also I think they use a bigger turbo than the Ko3.

They might not be getting the high intake air temps I've been seeing on chipped street cars

I can't help thinking it's a heat stress
failure issue.

Is this a recent pic...or from several months ago. I know you had to do some work to repair one of them from the San Diego race. I am just curious how it turned out.

Thanks

about a year ago you posted what everything weighed as you removed it from your car.I had this post saved but i lost the link.could you please repost? thanks in advance!

I don't think that I posted everything......if I did, I no longer have those figures.
Our carweighs right at 2,925 lbs without fuel and driver. Our roll cage weighs about 160-175. The seat/belts/fire system etc weigh about 50 lbs.

The stock car dry weighed 3,500 lbs, so without the above, we removed about 800 lbs.

These pictures were taken two days ago. The right frame rail was pretty tweaked pretty bad from the shunt in San Diego, but we straightened it at the track. We tweaked it again in the race due to me trying to push start a Corvette in front of me (well...he braked going down the straightaway when I was on his tail drafting on him) but you can't really see the bend.

About the crash......I ran about three hot laps in practice and then pitted to let the brakes cool. While I was sitting in the pits, unknown to me, the piston seals litterally cooked. When I went back out on the track, I tested the brakes and they were ok. As I went onto the straight.... I was going about 120 and hit the brakes to slow for turn one......nada...zip...nothing...the pedal went all the way to the floor and stayed there. I had about a split second to decide if I wanted to hit the concrete barrier head on...put the car in a spin and take my chances...or what? I was coming up on a slower car...a 993 that was to my right.
I made a split second decision to slip behind him as I was coming up and punch him in the rear...actually hitting him intentionally....so that is what I did. I felt that was better than hitting the wall head on or even sideways. I tore up the right front of my car and his left rear. I talked to him later (ironically, we had reapired his engine for him earlier that day) and he certainly understood...it was a self-preservation move.

We both repaired our cars.....we had to take a new left intercooler...cut off the top and bottom of the right, and make a new right from the two, since no one had a right.

During the race on the second lap.....I had moved up eight places on one lap...the rad. cap blew off.

By the way...we solved the boost problem...we could run two bar if we wanted too out of the RS4 turbos...we used a manual controller out of a 935 Porsche that I had sitting at my shop..works great.

See ya.....Don

When can I drive it???
