I have been noticing Vitos adds in atv mags advertising a Raptor intake spacer. Looks like a 660 spacer by the looks of the intake diameter(s).....but not sure. They are claiming 3hp increase and I would not be surprised if this is an exaggeration. BUT, if this $60 mod gives a solid 1.5hp it would be well worth the casholla if there are no negatives like torque loss, moves carbs to far back, etc. etc. Anyone have an opinion on this mod? Thanks.

 

If you add a spacer your going to move your torque band up. Your lengthening the intake, just like adding a tunnel ram. So yes, you will loose bottem end. How much? Who knows?

3Hp. You would have to have me standing right next to the dyno for me to believe that.

 

True....normally....but we have old info available here (I think still) from people more in the know than myself that touts otherwise.I may be asking to much for Raptor specialists to step up at this point and time. Appreciate the reply bro.
