I've heard nothing but good things about the PA head and mixed reviews on SLP's kit. Problem is I can get a discount with SLP
If I didn't have a warranty I would probably go with RKT's kit. Polaris will find ANY way to get out of warranties...

me and my riding partner both have rkt drop in kit in our 12 pros both 155 and both run very very well. my sled has the stock pipe and my buddies has the slp pipe. he had to add 2.5 grams of weight after putting rkt drop in kit in his sled it woke the sled up allot. there is a big difference in a stock pro and ours with this kit. it works very well i am running 63.5 gram Polaris weights and he is running 64.5 gram weights at 8k to 10k feet and holding 8300 to 8500. have not been around the other kits but i would recommend this kit to anyone.

does his kit change the power curve so you need to be running 8300-8500rpm?? I assume there is a range of compression ratios like the PA head?

 

[treedocker]

it changes everything from top to bottom, and yes it runs very good at higher rpms.

I built a 12 PRO with a SLP Stage IV for a customer and it just rips. He can almost climb with my 11 PRO turbo, granted he is 50#'s lighter. Just saying that this sled runs and is very fun to ride!

So for clarification...in three feet of fresh snow a stock PRO got stuck and your kit'd up PRO (pistons..head...stock exhaust..stock track..team tied clutching..???) went over the hill at 50MPH?

Any response to the above. I am a serious buyer wondering the same. EW

We have many 800 Drop In kits out there running. Just because they are not posting on SW does not mean they are not out there.

The drop in kits are running exceptionally well... Very happy with the results. They really do deliver.. The 858 kit is running very well also as is our custom patented head.. ALL 3 adding significant power to this engine..

The Pro with some power enhancement is a whole different sled.. So, we are finally enjoying the Pro with this new found power.

Increasing mid rpm range power is always good (and all of our kits do that) but I have never climbed a hill or raced anybody at 7000rpm (midrange).. So, we designed these kits for Mid-range power AND ,more importantly, top end, WOT power increases..

Last week in 3ft of new bottomless POWDER the difference between a stock Pro , DOO, or Cat and the Modded Pro was significant.. Stock Pro not being able to go up the hill and the mod Pro going straight up it at 50MPH... So, very happy with the outcome of these kits..

And we where was the Cat with your BB? I think I know!
