The better air flow to any engine is key.. compensated with a turn of a screw"fuel" and less restricted exhaust......I plan on polishing the horns on my 04 rx1 and the ports they mount to..The shinier , the better flow...I found 3" cone breathers with fans in them that I would adapt to each carb and delete the airbox...like a tornado set up......Manufactures claim 5 hp gain on a 50-150 HP engine.....I'm talking 4 carbs with its own little twister fan filter.........I'd like to know what some Sled Heads think about my idea.....Good or Bad and why...Thanks.
