SLP stage 2 or 3 kit for pro rmk's

[d8grandpa]

I have about 200 miles on my 13 stage 4. It is very strong in the bottom and mid, but we still need to find more top end. My friend with a new etec has, reeds, pipe, can and belt drive and pulls about 3mph more on a climb. It just slowly pulls away. We weighed our sleds at the beginning of the season and my pro is 25lbs lighter (the etec belt drive is about 10lbs savings). Overall he is a bigger dude and I figure there is about 70lbs difference ready to ride on our own sleds.

I was curios if anyone had tried the dyno port y-pipe, pipe combo with the pro compared to the slp pipe setup. I know on the dyno last year on the xp the dyno port pipe and can combo did make about 3hp more than the slp setup. But that was on an xp.

Was also curious if anyone has any results from installing extroverts, I really have to run my track tight and am pretty sure there is some track speed to be gained with extroverts.

I am pulling 8350, with 64gr belly busters in the primary. Holds rpm well and bulls hard out of the hole, but I just feel like its missing 3-5hp on the top.

Cheers

what are you getting for track speed on a pull in deep snow?

Stage 3 for sure over stage 2! Riders in our group all have slp setups that work very well. I will be upgrading from 3 to 4 this year on a 2011 pro. However not a big fan of the vforce reeds.

x2! Keep the stock reeds

I have stage 3 12.6 cr head, pipe, stock reeds and fuel controller running 64 gr polaris weights at 6,000 - 8,000 ft and around 8,000 rpm and here at home 1,600 ft 70 gr and 8,000 rpm. SLP map in the mountains is rich, but tolerable but could squeeze more out of it at home it seems fine.
