[DeTomaso] cooler air to carb

[Tomas Gunnarsson]

Exactly, and didn't the early cars have a cold air snorkle system down along the firewall originally? I think Chuck had pics of that on his site.

  Same as used on many cars like my 944, a simple ducted route to unheated air that is sucked in by the induction system only.
  It works or they wouldn't do it at Porsche.

    Richard,

    I took a stock aircleaner in rough shape and modified it. I made a new snout to match the original aircleaner hole that went from a rectangular cross section to a round cross section. I then bought flex hose as used for kitchen fans (i.e. it doesn't burn easily) and routed it towards the ground. At "ground level" I simply made a short tube to clamp the hose to and bolted the tube to the chassis. No scoop, no flaring, just a straight cut tube end that points to the ground. I also filled the vacuum operated port and duplicated the snout/hose installation on the drivers side of the car. My air cleaner air temp is marginally above ambient at speed. All this is barely visible standing behind the car looking into the engine bay and to the unknowing appears stock.
