[DeTomaso] Techno question: cold air induction "turkey pan" style for the Pantera

[CharlesMcCall]

I've seen a couple of sealed systems that drew outside air into the carb, but know of nobody that has dyno'd their engine before-and-after to know how much it helped. 

I'm thinking right now of Geoff Peters' Dart blocked stroker, which is stout enough on its own without outside air... it has a carb box and a pair of flexible tubes running to the gills, all fabricated by Johnny Woods

Dear Rob,

It doesn't seem to be too difficult to seal things up. The real question is how much more "cold" air can be inhaled by the engine and how much that would translate into more horsepower. I think that the answer is that only a small benefit *might* be derived. I was hoping that someone would share their first hand experience. We shall see.

Warmest regards, Chuck Engles

I think it would only work if fresh air was being introduced from
elsewhere.   The Cobra pan works because the carb is sealed against the underside of
the hood, and 100% of the engine's air intake is coming through that hood
scoop, from outside.   On a Pantera, a cold air box with side scoops achieves
the same thing.   But putting a setup such as you describe on a Pantera,
without any other modifications, wouldn't achieve a darn thing, because the
engine would still be forced to breathe the air that's around it, and that air
is flowing from underneath, past the floor of the apparatus, and then into
the engine.

Or so it seems to me....

Mike
