RRP Exhaust setups

[danielpak_ek9]

So currently I'm running an RRP laydown and RRP waterbox with water being injected into the box. From my research, people have been saying that the RRP box is not that great since you can experience water injestion into the motor since there isnt much baffling in the box. With that, I sometimes do experience that when riding my ski. So I picked up a PFP box to solve that problem since its baffled much better that the RRP. My question is to all those that ran that same setup. Do you still inject water into the box? The waterbox doesnt have a port to install a fitting. Im thinking to get a bung welded on there and get that sorted. But before I do I was curious if anyone here is running an RRP chamber with a PFP waterbox and how you guys set that up.

Same setup, no water injection, you’re chilling

I believe the rrp instructions call the waterbox injection optional

How hot does your water box get? Do you run a bigger jet into your head pipe to get more water thru the chamber?

Never sizzled water on me but hot enough to be uncomfortable to touch thru wet gloves after about 5 seconds
Between a 95-110 Jet depending on water temps.

I'll give it a shot. Thanks for the input

We run our 1200 at about 120°, the RRP pipe about 125 to 130° and the RRP water box I would love to get to 130 to 140° but with no water in it at all, it only gets up to about 129°. You don’t want water to sizzle on the RRP water box but if water steams that’s about right.
