Limited Edition 8v Supercharger Kits Available

[ggehrke at gmail.com (GGehrke)]

Couple questions:

+Timeframe?  When would they need to be ordered?  When would they be
built?  etc.

+Okay so I understand the bit about piping and engine management are
required, but what else (at minimum) would be either required or at
least a very good idea for this thing?  Would a front crossmember
reinforcement be necessary?  Different fuel system?  I'd imagine you'd
need to make provisions for more fuel if you want more power... Oil
system modifications?  Drivetrain?  (beyond just "well adding a quaife
would be nice" - would this trash stock transaxle, cvs, etc).  Any
recommendation for prepping the engine for it (i.e. I'd imagine at the
very least a new headgasket).  There's no intake manifold or
intercooler with it?  Any details on what exactly Peter (or others)
did to their CIS systems to use them with it?
+What sort of options are there for pulleys and such to vary the
amount of boost/power?

Peter started designing this for his Cabby in the late '90's, just for fun. A couple years ago, he made a few (5?) copies of his kit for interested people such as myself....again, just for fun. I can't say how happy I've been with it. Now, it seems enough people have convinced him to do another batch, so he told me to see if any of my friends were interested.

If you've read Corky Bell's "Supercharged" book, you've read about it. In fact, Peter has spoken with Corky and Kenny Bell in the process of designing his kit, in addition to Autorotor themselves. This is the same charger design used on the 500hp supercharged AMG Mercedes V8s and the Ford GT (licensed in this case for production by Eaton...seems Eaton decided their own aren't good enough!). Also sold by Kenney Bell, Flyin' Miata, BBM, and others. Pretty much everything is CNC'd out of billet, with a couple of modified OEM VW brackets.. It is IMHO beautiful work, and so beefy you could support your entire car easily from the main mouting plate.

You're left to determine your own intake/boost tubing, intercooler arrangement, and engine management. Since it was originally designed for a Rabbit/Cabby, it also required a little trimming of the bracing under the hood to fit in my Mk1 Scirocco...I don't know if anyone has ever mounted one in a Mk2 yet, but I imagine it wouldn't be any worse.

>  Just to repeat: you are responsible for fabricating your own intake to the charger, as well as the boost tubes and whatever intercooler setup you desire! Then, you are responsible for making sure it is fueled correctly! If you are comfortable swapping to some sort of programmable EFI (Digifant 1, Megasquirt, SDS, etc) and can weld some mandrel-bent tubes together, you can basically duplicate my arrangement. Or, you can stick with CIS, and play Dr. Frankenstein. The choice is yours!

But properly tuned for moderate boost with an intercooler on a low-compression 8v, and I don't see any reason why you shouldn't expect somewhere around 150whp...at least. That's totally just my guesstimate...YMMV, 'natch. But when you think about it, going from 90 at the *crank* to 150 at the *wheels* (well over 50% increase) would be a pretty good bump.

Personally, I think he's crazy for sticking with CIS, but he manages something like 195whp/205wtq with that setup!

>  As for myself, I run mine on a PG block with Digifant 1 from a Corrado and a custom chip from SNS Tuning. I have a *heavily* modified engine (forged pistons, balanced, crazy head porting, bigger valves, etc.), an air/water intercooler, and produce 235whp/205wtq. That is still on 93 octane pump gas and with a couple smaller pulley sizes yet to go. It is currently listed as the 2nd highest WHP supercharged non-crossflow 8v engine on the Vortex...and higher than just about all the supercharged 16vs I've heard too.
