Twin Turbo Update... (10/13)

As most of you know, my twin turbo project is coming along pretty
nicely. I spent a few hours at Callaway today with Chris McCulloch
talking to Mike Zoner. We discussed intercooling and exhaust options. 
The setup would be either one intercooler in in each corner (at a 45
degree angle from vertical) and duct the hot aftercooled air out the top
of the hood with an exiting duct, or weld two intercoolers together with
a plenum in the middle and mount that in front of the radiator. For this
set up, I would have the pressurized air enter the intercooler plenum at
the top corners, and exit the plenum in the bottom center. That seems to
be the best way, although it would be cool to see intercoolers looking
down my hood!
  The easiest way to build the headers will be to use Weldels. These are
pre bent pipe pieces that you weld together to make something :)
Callaway used it for their twin turbo vette, but they are damned heavy!
The other option is using T-304 SS tubing, but then I have to mandrel
bend everything. I have to check the Omega catalog now also, since I'd
like to put a K-type thermocouple in each header tube to help set up the
fuel injection properly (and prevent a meltdown!) Callaway had a twin
turbo there that we looked at (getting upgraded!) and also a C7 vette
with neat carbon fiber ductwork everywhere. I think the 98 Camaros
should use those headlights (as if they'd fit) instead of the factory
jelly bean style :p I've got parameters for turbos, and now just need to
look at the spec charts and choose a good one! 

Later,
