Supercharged M3

I've had the Dinan supercharger kit installed on my 95 3.0 L M3 for about 2 
mos. now , and it has performed exceptionally. 341 hp is more than adequate, 
but the speed bug has already bitten. I want more power, and I've got a number 
of ideas and quite a few questions.

1. The supercharger as geared only reaches about 6.2 pounds of boost at the 
6750 redline. The Powerdyne supercharger in the kit can only spin fast enough 
to produce 9 lbs. of boost.The M3 engine can only handle about 7 lbs of boost 
before it starts to ping and detonate. To raise the boost higher low 
compression pistons would have to be installed, and low rpm driveability would 
be sacrificed. I also don't want to spend that kind of money on top of what 
I've already spent.  I want to know if the supercharger could be geared to 
produce 8 lbs. of boost at a 7100 rpm redline with a wastegate installed to 
start blowing air at 6.5 lbs. of boost. Would the higher gearing draw more 
power from the engine and cancel out any benificial effects, or would the 
gearing have little effect on the amount of power that the supercharger draws 
from the engine? How would torque be affected across the whole powerband?

2. How could an intercooler be installed? A small intercooler could be 
squeezed between the SC and the throttle body, and a NACA duct could be cut in 
the hood to provide insulation. A intercooler could be mounted near the bottom 
of the car, or an intercooler could be mounted behind one of the front air 
ducts. The last two options evolve elaborate tubing with multiple twists and 
bends that could result in a loss of pressure, but they could accomadate a 
more efficient intercooler.

3. The engine internals could be altered. i.e. low compression to increase 
boost or stroker. This is more money than I'm willing to spend, but the gains 
would be large.

Changing the gearing on the supercharger voids the warranty. Dinan won't give 
me a straight answer when I ask them if they're working on any further 
developments. I just want some small gains for relatively small money.

Who is this Jim C. guy? What do I need to do to get in touch with him? I want 
a chip with a 7100 rpm redline in all forward gears. I hardly ever operate the 
car at redline, but when I do the 6750 redline is just a bit restrictive. I 
bounce off it quite often under hard acceleration. I'd like to shift at about 
6750 when I'm punching it.

Is it possible to install the European six speed transmission? Is it possible 
to change the final drive ratio to 3.23 like the 3.2 liters or even higher 
(3.3)? What would cost be?

How much do the aluminum doors off of the M3 LTW cost?
