600 HP numbers??

[pura vida]

Yes, they have my top end for the 2012 RMK right now. Just came back from plating and will be shipped back to me today. Price isn't that bad - $1500-1600 for the 660 top end kit and ECU reprogrammed.

Not sure why they aren't listing it on their website though, still list for the carbed engines.

but does that count all the other necessities? pipe, reeds (maybe not necessary?), clutching, intake, etc?

probably not and it is the entire package that carl's puts together that really makes the thing shine. NOT all 660's are created equal. would still love to have one. not this year but i will have some up close, first hand experience with one with all the goodies on it. i'm betting it's going to be a ripper as long as there aren't any low elevation bugs in it similar to what popped up in the cfi-4.

There was no Pro Ride 600 in 2011
Was still in the IQ chassy

This is the first year of the 600 engine in the Pro Ride chassy

Yes I know. I was listing the differences between last years 600 in the short track 600 V this years and there aren't any. However it sure seems like a very different motor in this years Pro-RMK. It would be great if someone got into one and looked at all the differences. I feel Polaris is being quiet and letting their machines do the talking after the 800 low dyno noise. The new pros rip and the motors are solid. New mills are usually put out in the mountains first, lets face it if it's gonna break a mountain rider is going find out. Aren't you having work done by Carls ? I can't think of a Polaris dealer who has more of an insider track than Carls, ask them.

As of now, the recommended kit includes the following:
660 top end and ECU reprogram - $1600
Clutch kit - $300
SLP air intake - $65

SLP doesn't have a pipe for the 2012 600's yet. Not sure if I will buy one once they release it - $685 seems kind of expensive.
Reeds? Stock will be more than fine.

I live in MN and ride out West a couple times a year. I ride at 1k feet here and my first trip will be in CO (11-12k feet - Buena Vista, CO). That should be a good mix of min/max elevations.

 

[yep]

Hahahaha, Ya right. Maybe more than a 10 year old carbed 700. The new chassis is what makes the solid 600 a much better sled.

Right but we're discussing horsepower and the fact is that Polaris quit building the 700 for a reason. Otherwise why not put a 700 in it if it was making more power then the 600.

It's all about money and marketing in my opinion. The 600 is used on the race sleds and the 800 is the common big engine. The Polaris 700 would be left in a class all it's own and would require additional parts to be manufactured costing Polaris money. They are in business to make money and HP numbers are a thing of the past, thats why they don't post them like they used to.

It's kinda odd that they didn't use the long stroke race motor for the new 6. Couldn't be that hard to inject it.

On the micro fiche Polaris is using the same gearing and secondary clutch setup for the 600 and 800 pro. The primary seems to run the same spring and lighter weights of course but if the 600 can pull close to the same setup as the 800 it must be a pretty strong running motor then. If it would snow soon I Could give u a ride report.

I rode with my dad on Thursday and he bought the 600 pro this year and I got the 8. It wasn't the greatest snow for a good impression and he was taking it easy to break it in. My 1st ride on it felt ok, the motor felt really smooth and responsive, but obviously lacking in torque compared to my 8. Later on in the day my dad changed weights and the spring in the primary and I rode it again and it felt a lot better. It pulled pretty good through the midrange and not bad on the top. I had an 07 600 rmk last year that my wife rode that had a SLP pipe and can on it and I think the pro definitely felt stronger. Hard to get a great comparison though after not riding for 5 months. We also raced up a hill for about 300 yards that had soft and hard windblown snow and my 8 with a 163 would take him by 4-5 sled lengths over the top. Not a great review for ya but hope it helps a little.

thought id share some info from the service manual that was posted today regarding the Pro 600 and the 600 RMK "engine differences"

Model numbers do differ:600 Pro-S4452-6044-OL6G vs 600 RMK-S4316-6044-OL6G
but so does the 800 Assault & the 800 RMK...and there aren't two different 800 egines

The important info:
displacement for both - 599cc/2
bore for both-3.04/77.25
stroke for both-2.52/64
type & number of fuel injectors for both-DC-CFI-2
throttle body bore for both-46mm
top gear for both-20th
bottom gear for both-42th
drive clutch spring for both-black/green
driven clutch spring for both-black/purple
clutch weights-6-8k 10-58 weights

so as you can see these two sleds are identical mechanically speaking
there ARE NOT 2 different 600 engines
which was also confirmed w my sales rep here

the differences are as i stated above:

different steering post, running boards, handlebars/riser set up, suspension, winshield, the 600 144 has an extra cooler at the front, and of course track length and graphics

but the determining question....what are the HP numbers...who knows!!! LOL!
my guess is still between 125-130HP +/-

either way, anyone on a 600 PRO RIDE .... is gonna have a TON O FUN!

BINGO, Polaris was the last hold out on the 700.

First: The guys that want HP are getting 800's the ones that do not need the ponies get a 600. The 600's are arguably more reliable and in the PRO a fun ride no doubt.

Second:The cost of a 3rd engine that is 10-13% (Based on 125, 140 and 160 hp from the 6,7 and 8) different from the engine above and below it is not a viable build option. A different can, clutching, track angle etc. will put the 600 even closer. Why build a sled that a few people will buy when you already make two great choices.

well said my friend

Got 30 miles on my 600 and this motor is strong. I had a 600 etec last year and the Polaris motor is a lot stronger. I think with a light rider it will keep up with some of the 800s. Should find out tomorrow.

They've been running the same setup for 10 years on the secondary helixes, springs and primary springs for 6/7/8's, only thing changes is the weights. Lots to be left on the table for performance from clutching on all.
