[urq] Bigger IC - group buy???

[urquattro at comcast.net]

Brandon,
Sounds like a really cool idea. I have daydreamed about such an idea myself. Obviously I've already gone the hard road with the full 944t unit myself, but have been interested in developing a bolt-in "middle ground" solution just for fun. I think the increased thickness -would- increase the cooling quite a bit, as well as increase flow (most of the heat exchange area is on the longer horizontal surfaces, or should be at least). Obviously, uberkill shrouding would be necessary to maximize efficiency. 

I had imagined using a chopped 944t core and the end tanks from the stock IC, with simple 4-sided "wings" on each end to adapt the end tanks to the wider cores.  Material cost per unit would be minimal this way, and a welder with a jig could devise the "wings" and cuts to the end tanks quite easily, I imagine.

Guys- 
Following my decision to not use the 944T IC due to alternator issues,
I'm talking to Bell Intercooler about making a custom IC from one of
their stock cores.  www.bellintercoolers.com  Bar and plate
construction. Dimensions would be same length as stock so that the
alternator can stay put, same height, basically, but make it thicker to
increase flow - go to about 4.5" thick instead of about 2.5".  By
looking at their tables, the stock IC looks like it flows about 250 to
300 CFM, whereas my design should be closer to 450CFM.  Any additional
cooling would be nice, but really my goal is increased flow as I feel
it's a bottleneck on a chipped 3B w/ RS2 turbo.  I'm assuming there
would be very little if any additional cooling.  I don't see any reason
it would not bolt right in as I used stock plumbing when I had the 944 T
IC in there, and it is 5.5" thick.  I still have a few things to measure
twice, but I want to move forward with this little project.
 
I don't know if I'll be able to order a bolt-in unit - I'm pretty much
assuming I'll get something as close as possible, then have a local guy
do some tweaking with welder.  I don't know.
 
Any thoughts?  Anybody else interested in going in on something?  Core
price is $219 - no idea about pricing with endtanks yet.  Have not even
asked them for a group rate - but will if there is interest.
