Am I the first to have driven with a ROOTS SUPERCHARGER installed on a S4?

Andy - did'ya maybe do a little too much blotter...back when Jerry was still kickin' it?

You should keep the manifold pressure below 8 psi on that thing. The cast pistons are pretty tough, but turn it too far and you will have major headaches.
That car should run quite nicely on 5 lbs. of boost with no issue at all.

Great job Sno. I can't beleive you got the hood to close. Do you plan on a larger blower? I heard that it is possible to crack the windshield with out the strut brace in there, so be careful!
You have to give us some 1/4 mile times now, you know that right!

You are the man!! Keep us posted. I for one would be interested in a kit, when you get the bugs worked out.

absolutely amazing to see a roots on a 928. How did you relocate the throttle, kickdown and cruise control cables???? This is amazing! Great job!!! <img border="0" alt="[thumbsup]" title="" src="graemlins/bigok.gif" /> <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" />

Thanks everyone that replied.
I'll try to answer a few more questions.
PorKen, I must have to believe I could do something like this
John, Yep I plan to keep it down below 6 without intercooling. I have a pretty good idea of how to build this manifold to include a built in a air to water intercooler though.
Gerry, No plans for a bigger blower. I went with this because it is big enough (the biggest of it's type) and readily available realitively inexpensively as a rebuilt unit. ($600-700 USD rebuilt from <a href="http://www.canadiansupercharger.com)Two" target="_blank">www.canadiansupercharger.com)Two</a> other important factors for the Jaguar Eaton M112 are long snout and rear inlet.
Eurospec, the only cable that was changed was the cable to the throttle body from the linkage. That was pretty simple once I fugured it out.
Pete, I don't know what is up with Huntely's kit. I was hoping to draw him out with this post to give us an update. I had offered my car to him as a test car at one point when I was tired of my project.

I was checkin' my neighbor's Ford Lightning last week. He pointed out the water intercooler which lives down in the 'V' under the SC. Is this how you're figurin' to place the intercooler?
He also noted that the rear entry SC's were more efficient (vs. the top entry on the stock SVT Lightning engine below).

PorKen,
It would be similar and use the same intercooler. The GT 40 engine looks very similar to the Lightning and Mustang. It has a rear inlet Eaton.

John,
I'll take it to the dyno soon to tune. Maybe this weekend if I can find one nearby. It still needs quite a few finishing touches.

I would strongly recommend you check closely for detonation. Remember, you have 10+:1 compression in that thing on cast pistons. Your theoretical limit is probably somewhere around 5 psi at the manifold.
I bit the bullet and am in the process of installing forged pistons in the Bastard to allow me to up the boost....just a bit :0)
