Sun Oct 12 23:34:56 EDT 2008

Just so we don't put 3-fan Chris and the other non-racers too sleep with all these cooler air to carb and oil cooler biz lets talk  "diffusers" like on the back of the McClaren....thinking of ways to clean up the bad air at the back of the Pantera above 170-175 short of turning it into something that no longer resembles a Pantera. ;-]>
  Dawg, keepin it.... kinna stock
