Grassdragger, I like it! I was planning on making some ductwork to channel some cold air to my air filters in the future. Your setup seems original to me, but I like the theory. pretty cool!
And on the dyno, you have no 15-25 degree cold air coming in the vents( and I'm sure anytime your going over 30 there lots of it), so OF COURSE IT WILL MAKE LESS POWER!!!
Obviously warm air is less dense, so therefor less oxygen to accelerate the fuel burn. I know it will have less potential energy if you will, making less power. Blah blah blah it's common sense man, but is it enough to matter in this application where I'm cranking along in cold winter temps with lots of vents in the hood? probably not. I mean sure for all out strictly racing I would make sure i had the coldest air possible. In racing EVERY little thing adds up and that's how you win. Well that and a driver who isn't scared of anything! haha
if you really wanted to get picky, I but you gain a little bit with any kinda of pipe before the carb regardless of cold air or warm air. The air is probably not as turbulent. Bad for fuel atomization, but better for flow and scavenging effect. That's why you see every old carb'ed high end race car has velocity stacks. airflow is airflow.
oh ya, and of course if you unscrew the top of the airbox you can get at the rubber boots that go over the carbs. How else would you do it without taking the cover off??? I used to persuade the rubber over the carb with a long dull regular screwdriver. It's still BS tho. JUNK!
THE ONLY thing I have to undo to get my carbs out is the 2 clamps holding them onto the boots at the reeds. The way it should be. It's a toy, it should be simple.
