Thanks, no detonation issues with the head
Thanks

Thanks for the reply, had any one ran one side by side with a stock head 850 ? I am trying to decide if it's worth it as I am in Canada and have to deal with the exchange rate. I don't want to deal with the Det issues guys have been having with putting a pipe on the 850's riding 3000-6000'. Thanks again
I rode with the SLP Power Dome on my 850 last year. I ran the whole stage 1.5 kit. I had zero issues with the head and just as @wfieldin said I also had zero detonation. Here is a 40 second WOT pull .
My buddy has 3400 miles on his 2020 850 with slp head and can. (Low elevation domes)
runs strong and no detonation issues.
SLP Outlaw Stage 2. Head, twin pipes, clutching, and tune. 8000' and up. Flawless. I run 8oz. of VP C-12 everytime i fill up. Don't like dealing with octane boost in a plastic bottle that i don't know the shelf life of. I'm good with using the VP the following winter if i don't use up what i bought for this winter.
This sled is so much fun, throttle response is excellant, and it just never quits pulling. I have always been pleased with SLP's performance and this set up is no different.
Kurt's gear down in the trailer. Hope i can hang on at my age.

just curious, what is 8 oz of c12 going to do at 108 octane with 640 oz (5 gallons) of 91 fuel? even to mix 5 gallons of 91 up to 92 octane you need 38.4 OZ of C12....
I am not a scientist or chemical engineer. I go by experience and what SLP recommends. They recommend 1oz of Lucas oil octane boost/gal. of 91 octane above 5000' and 20% race gas below 5000' for detonation. I used the octane boost in a Pro chassis SLP Stage 5 that my son raced without issue. With out the octane boost it would detonate and go into limp mode. In his Stage 4 Axys i started using C-12 mixed with 91 octane with no issues. I called SLP about using race gas at elevation rather than octane boost in my twin piper and was told that would be fine and i would need just a "splash". I find the octane boost hard to find without ordering from Lucas and can't find a shelf life for it. I live at low elevation and once in while run my twin piper here, so the race gas just the right mix for me also. I still have all these sleds and all still run flawless. I just settled on 8oz for no other reason than its easy to measure in a ratio rite.
Ran one for the last 1000 miles on my 2020 850. Rode from 3-10k. Always just ran pump premium. Rode the sled stock for 1 year. Runs awesome with the head, and never had any det issues.
Ran one for 600 miles last year on my 21 from day 1... 8-10k ft...never had detonation ran premium fuel no additive... only issue was gotta throw some extra weight in the clutch this year. And hopefully the update driver kit and she will be nasty.

Similar question, i live in northwestrn BC and the majority of my riding is 3k to 6k ft and i am thinking about getting a head for my 22 RMK Matryx, my dealers mechanic who actually rides says it is a waist of time and money for our elevation. I see a lot of different heads out there and am just wondering if anybody that rides in similar elevations has tried out a head and what their feelings are? I don't want to take the word of 1 guy, I would rather listen to several people and make an educated decision. Thanks
