Charlie,

Sounds like a "turkey pan"(cold air box). By drawing only outside air into the trumpets, you get a major boost in horsepower.

I watched a guy aim a house fan at an 8 stack EFI manifold(Cobra/302W on a chassis dyno). Voila! 20 more horsepower on the next dyno run! [img]/ubbthreads/images/graemlins/cool.gif[/img]

At some point, I will have a turkey pan built for my car. I've had a scale engineer's drawing of my manifold for over a year now, just haven't gotten around to it yet. A local machinist, who does work for NASA, quoted $500 for a 6 piece, CNC cut, screwed together pan. I told him that I wasn't planning to drive to outer space, but the price was still $500.
