FYI: NEW PRODUCT... POWER ADDICTION PRO-RMK 800CFI BILLET HEAD AND HPS SILENCER COMBO

[Clarke673]

I was under the impression that the det sensor listens for a certain frequency that it thinks is detonation. I am wondering if the head changes the frequency at which the motor will detonate negating its effectiveness.

the same head brad maid for the dragons will bolt up to our new sleds. I am not aware of much changes. It is not only the higher compression, but the shape of the dome.

I did extensive testing last year on my 09 dragon i was building for hillclimbing and after i ate my first set of pistons, i put hte stock head on because i had a long trip planned and didn't want any issues. I took the sled for 2 hour night ride and went home, added a bit more fuel to my map, swapped heads that night and enjoyed some epic snow with no bogs.

Thease heads work. nuff said. Buy one and enjoy it, or get your *** kicked by another stock pro that has $400 more into it.

Finally got to ride my sled after putting on head and can.All I can say is wow.Sled seams to have a lot more snap down low and in the midrange. It seemed to lose a couple hundred rpm during the day But I think it was heat related. I cant wait till we get more then 8 inches of snow to really see how it goes. The hps can does seam a little loud, but I can put stocker back on if need be. I would recomend this product to anyone on the fence.just get it it works.Thanks

I wonder how a tuned MDS set up work with the head......

Did you have to add weight to the clutches from stock what elevation and what weights

 

[RZRNUT]

I have 2 Pros. one for me and my son. His sled always ran a little bit better. We both have 163s. I put the 13.6 Head on mine and did the track mod as well. We both had the HPS cans already on. I was running 10-58s at 9 to 11k elevation, I put 10-60s in mine. Noticed a very nice increase in throttle response. The low and mid range is much more crisp. No problems with the DET sensor at all. I was seeing 8000 to 8100 rpms in 18" of heavy snow. A great Mod for the money. Now my sled runs better than my sons. If only I could just ride like him.

I have 2011 Pro 163" ran it stock all last year. This year put HPS can and 13.1 head on and I ride at 5-6000ft.
Last year I was running 10-62 weights and it ran 8100-8300 consistently and I was hitting the rev limiter once in a while. I knew that I needed a little more weight.

This year I installed 10-64 weights and I am still hitting the rev limiter once in a while.....That to me proves this head make more power.

I am not sure if the Hps can does anything other than loose weight. I would like to see dyno results with this can.
I guess if a dyno chart came out showing a slight power loss we all would be dumping these cans and HPS wouldn't be selling anymore.

I have not added any weight. I'm riding at sea level to 4000 ft. I di notice a couple hundred rpm drop but I'm running an old belt and it was after the clutches got warm. Came back after letting it cool when we stopped for a break.

Last couple days I unloaded at about 2k...which is the first 2 days on this head (already had HPS)....running 13.6 domes....experienced the DET code twice...turned it off....started it again and it ran fine as long as I didnt really get on it.....also had a definite bog if I tried WOT under 5500....but once at 5500 it ran and worked great.

Pump fuel?

Pump fuel?

X2 Thats asking for trouble!

X2 Thats asking for trouble!

Closer to begging than asking. I ran those domes for a month last year and needed 96-98 to keep it cool...but they RIIIPPPP at sea level hahaha...I was fully loaded on weights, 2g more hardly kept it inline..it was crazy.

Oh and Tim I got your weight rivets in today...ill ship em next week swing through the shop on your way through anchorage sometime and pay

 

[MNSLEDNECK56308]

Yes, that was exactly my point, he doesn't mention anothing about the fuel he was running and if he was running 13.6's at 2000ft on pump fuel its no wonder he had a few hiccups!

RZRNUT you are leaving some snort on the table. Trust me I ran the same setup (stock helix spring combo and just threw weight at it...lots of R's and 250 of heat settling on a climb or trail to deep snow) and found another substantial gain from a better clutch kit. The Carl's Cycle Sales setup for this application is DEAD ON MONEY! My 155 pulled 8050 on a good climb in the Trinities on Sat at 8000ft with 64 grams. It's the exact clutch kit that I run at McCall from 5500 to max 8000 (mostly mid 7000s). HOW MANY PEOPLE ASK YOU IF YOUR SLED HAS A PUMP GAS TURBO AFTER THEY SEE IT GO UP A HILL?

The real gain on this application is THE COMBO OF head, track, and clutching...all on stock exhaust. Do these three things and your sled destroys a stocker. RZRNUT you already did the scary stuff in the track trim and head...NOW CLUTCH HER AND REAP THE REWARDS!

 

[Finnlandr]

Pump fuel?

94 octane.....if I have to start at 2000 should I run a higher octane?

 

[skippy]

94 octane.....if I have to start at 2000 should I run a higher octane?

Absolutely!! The 13.6 domes you are running are meant to be ran 5000' elevation or higher using minimum octane of 91 anything lower then 5000' and you will have to start mixing in some race gas in order to not detonate. If you don't want to mix gas you might want to think about getting the 12.5 or 13.1 domes depending on your riding elevation. What elevation do you mostly ride at?

 

[Finnlandr]

^^^...ride mostly above 5500 which is why I bought these domes....but traveling to other places like I just did I had to start out lower....would 91 + octane boost work?...110 too much?....thanks for your help

You could mix up to 95 octane either using a high quality race fuel concentrate like Torco or Klotz, or a blend of av/rav gas whatever works, but I would not pin it anywhere below 4k elevation...like I said, i needed 96-98 right at sea level-3k

Thanks IQRIDR

I'll call you Monday. I'm on the IR but could med up and make a run if I was going to feel the 1100! That would be worth the pain!
