weird drag question
Seeing as a 1/4 heat soaks the engine, would it affect the aerodynamics to do the runs w/o a hood? and would it help at all with the wind on the s/c? usually aerodynamics are important around what, like 100+? and only doing 115-125 mph tops a run wheres the real loss?

i think this will be a positive -- you will gain in cooling -- and you can set up a simple RAM air setup by removing the snorkels ---
You could lose a tad in aero and looks-- but you will also gain in weigh reduction --
So - that is 2 big pluses in the performance area -- maybe the slightest negative for wind drag -- and a minus for not looking so good --
Also - a big plus in sound because that Supercharger will whine like crazy.

At least not at these speeds my friend.
DRAG FORCE ON A ONE-SQUARE FOOT SQUARE PLATE
Speed
Drag Force Horsepower Required
to Overcome the
Aerodynamic Drag
0 mph 0 pounds 0 hp
100 mph 33 pounds 9 hp
200 mph 133 pounds 71 hp
300 mph 299 pounds 239 hp
Basically, areo dynamics do not mean much below 150MPH. A quick history lesson is from NASCAR when they would trade hoods and front fenders on the super-speedways and still win. Talk about drag

I've seen a 55 with a removable roll cage in it, but seriously if you can get your fastest passes at a track rental why go and slaughter our cars even more just to be allowed to run below 11.49
