Supercharger 3rd week, ugly charge tube (temporary). Carbon fiber Air to Water aftercooler
<center><img src="http://pictureposter.audiworld.com/131990/s8_number_5_049.1.jpg"></center><p>
Keep in mind the pipe and rubber from the compressor housing to the throttle body is just to test the units operation. I will also incorporate the bypass valve into the new charge tube/aftercooler intake tract, this will give a much cleaner look and also eliminate most if not all off the 1'in hose.
Currently I have this setup working and running and this is what I discovered. The Audi 32v V 8 does not seem to mind boost thus far and neither do I, LOL. But too date I have not done any hard driving as the car now needs to be tuned. The smartest move I made was to put the compressor housing on the drivers side allowing nothing to need modification. The 1st challenge;the Drive belt setup, which is the product of about 10 to 20 engineers collectively thinking on lunch break. As you may already know it was no easy task to rout a belt under and up the side of a forward mounted engine mount. Everything else was pretty cut and dry. The second challenge: intercooling, I was going to turn the supercharger volute 180 degrees toward the cars skid plate and pipe and plumb a front mount air to air intercooler. But I had reservations of turning the engine bay into something I always see on rice tuner cars, miles of pipe and holes in every corner of the body's plastic underbelly and radiator support. So my solution is to mold a carbon fiber "box" in the shape of the passenger side valve cover that extends all the way over "length wise" to the throttle body and compressor outlet. This carbon fiber housing will hold a water to air after-cooler.
I will be building this in junk plastic this week first to make sure the hood shuts.

Before he can give an honest opinion ...
he really needs to get the finished car onto a dynomometer and have it custom chiptuned, as he mentioned.
That could be $500 to $2500 depending on how much shop time it requires.

I have to give you credit, initially thought this was going to be another wishful thinking post
there have been a bunch of people in the past who have threatened to put a turbo or supercharger but then you never hear anything again.
You might have yourself a nice little side business (if you want it) at some point.

Re: Looking great

That's just not true.
So many speed shops cater to german cars and Audis in particular. I can spit and hit 2 tuner shops with dynos from here, that I'm *aware* of.

Alcohol injection is also an option
First off - you rule! I'm glad somebody finally said 'damn the torpedoes' and did this.
As an engineer who has built a few cars - nearly from scratch - I just thought I'd chime in here...
There are a some shops supercharging stock engines with alcohol injection up to 1 bar or more. There are computerized alc. injection systems that limit boost if you run out of alcohol and offer rising flow rate, etc.
I am already running an ABZ engine using a standalone ECU, which I doubt would play nice with the transmission computer, but I suppose anything is possible.
Keep it up and let us know when we can buy that bracket from you (!)
