TPI low boys in airbox ?

[NY_Nytro]

Has any tried TPI low boys in the airbox lid on their RX?

I remember seeing an article awhile back in one of the snow mags.

I have used them in the past in my last sled (Cat) with good success.

They work but you gotta go up on your main jets.

I was also interested in these and the picture on there website shows 5 of these Low Boys installed on an RX air box! This looks like a very effective way of gaining power!
Has anyone installed 5 of these to there air box and come up with the proper main jet size to use? And if you have, what where your results?

I believe DOM has them on his rx-1. I know he re-jetted also. This is all in combination with the flo commanders he installed. I haven't hard him complain at all.

Any Details? How many did he use? What main jets? What kind of performance gains?
