Losing the airbox.....any thoughts?

Postby mnsnowboy » September 27th, 2003, 2:47 pm

Well, I have been kickin' around the idea of losing the fat ass airbox on my '96 FIII. I was gonna run K&N's straight off the carbs to save some weight and possibly pick up a pony. Any thoughts and/or suggestions on this? Yes/no? I have never made an airbox mod to a sled before. I suppose I will have to rejet, not sure about that though. The sled runs mint now, and if this will help get 'er some fresh breath that would be slick as hell. Let me know!

Kick ass!

Just an opinion ............IF IT AIN'T BROKE........DON'T FIX IT !!!!!!
I know I'm gonna get beat up on this one, however I've always believed that STOCK is where a trail sled motor is meant to be. If it runs sweet the way it is, why mess with it ??
Again...Just one guys opinion !!

It's up to you, but unless you are changing jets all the time or need access to that area of the sled often there isn't much of a advantage. For sure the sled will be louder (ever turn your air cleaner lid upsidedown for that "cop car" sound?). Sled will probabily be kind of fat on the bottom also. The K&Ns will keep dirt out and they make quality products but are expensive.

Just my thoughts.

If your gonna be busting any, ANY powder then your gonna have snow coming in and getting sucked onto the k&n's. Heat from the enging will melt that snow and then refreeze from the air gettingsucked into the carbs. They will freeze up dude, think about it. Consider gutting the airbox and putting an extra filter in there or screen type filter. Could get costly if you freeze those K&N's up and you lean it out too much. Im with him ^.

I agree w/ these guys... but if you want a "little" more air to run a "bit" more lean(fast), drill ten 3/8th holes in the air box. It's a farmer method. lol

Leave it alone! You are asking for a lot of problems. You will be playing with the carbs all the time to get that thing to run right.

Don't SLP make a cool airbox unit that's easy to take off and get at the carb's? And also you don't have to rejet so rich to make up for not having the airbox?

I used to grass and ice drag a 96 F-111, and can tell you the stock air box isn't very restrictive. Pull the snow filters out, and it flows pretty well. It's designed to pull cool air in from behind the windshield, which is always better that filters pulling in hot air from under the hood. The weight of the box is negligible, although it is bulky and hard to get in and out. I'd pull the powder filters out, otherwise run it and enjoy it as it.

If you want to gain some performance, concentrate on chassis alignment, ski alignment, track tension, clean clutches, clutch alignment, and belt deflection. It's free horsepower, and won't affect how the stock engine runs.
