I spent a lot of time learning and looking into ram effect or resonator intake systems. It is used on cars, dragsters and even racing bikes but no one seem to have thought of making a new intake system for the raptor. I used some of the formulas to determine what would work best on a raptor and the 1st thing is have noticed is that the intake runners are way to short. The airbox volume is also way off. I believe it might be possible to make a new intake system for the raptor and get some extra power. Anybody working on this?

 

I made this, it's good for 1 to 1.5 HP. Adapter

 

going from stock setup I think it would add A LOT more!

 

Good post! What kind of numbers are you getting on the stock intakes too air box volume with the lid off? Engine builders have been sitting the carbs back for more intake volume...so you are on the right track.

 

Hey sixsixT... how much to make me one of those?

 

Yeah that's comparing to running without a lid.

 

Is this kind of the same thing as velocity stacks? Surely someone (aka sixsixt) could make some aluminum tubes for this.

 

Im interested in this to. How did you do that SixSix, it looks awesome! Is that a stock airbox that the dual filters are in? Make me one!!! lol. I didnt know Duals would fit side by side like that.

They have a radiused inlet somewhat like a velocity stack.
