I'm curious how many of you are running a turbo on the 600 and what you are thinking? Im currently riding a M8 (not stock.. but no turbo) and am getting a new sled this year. I'm not a fan of the new Cat- so i don't want to go that way... and i'm not going to get a polaris 800 (i don't mean to bash.... cause i have seen some of the new ones holding up great- but I still have seen some failures- and i'm not sold on them lasting along time) So just interested in how the 600's are doing with boost.... and if that would be a good fit. Thanks
Turbo RMK 600??
- Thread starter mr.deeds
- Start date
I know Shane Hart with HMturbos is building a 660 turbo for a friend of mine... I think they've been waiting for the turbo to come from aerocharger for a bit so they haven't been able to test the turbo... But shane has been digging into the 600 motor and he might be someone good to chat with about it!?
Last week we finished up the 2012 RMK Pro 660 big bore with self contained variable vain turbo charger with the Hm turbos water to air inter cooler for ex RMSHA racer Shannon Barngrover. The sled is 4 pounds lighter and the turbo 6 pounds lighter. It will be about equal to an 800 turbo with an additional 2 to 3 pounds of boost extra, but with more nimble feel. The power was very linear and easy to ride!
does it still run factory headlight
HiMark Recreation out of Utah use to boost 600 H.O's with great success. Those machine will run 14-16 lbs like nothing because they can take the higher boost levels without failure. I would imagine theory holds true on current 600

Do you mean HighMark Recreation out of Boise, Idaho? I ran an '06 RMK with there race gas kit at 14lbs about three years back. about 215 HP at that boost level. Very impressive and fairly reliable with the early carb setup. Rode it hard for two seasons and never had any motor issues. The 600 CFI still utilizes divoriced cylinders unlilke the Monoblock 800 CFI and has more cylinder thickness, this is one big reason why the 600 is a more durrable engine. MAG and PTO cylinders run a little different temp wise and reaction to heat soak varries from each side because of this (my theory). I think a '13 Pro 600 at 10-12 PSI would make a great all around sled. Like noted above the 600 CFI on boost is very comparable to a 800CFI on boost with a few extra PSI but with more linear power band. Most issues with the CFI2 800 in the PRO chassie was in the bottom end (crank). The '13 models have a different crank so hopefully that will cure the bottom end motor issues.

The HM Turbos '12 pro 600 RMK was one of the favorite sleds at turbo days in Lolo last April. At 6 psi non-intercooled it was an absolute BLAST to ride. Just after turbo days it was updated to the Vipec ECU, which made it capable of using the fuel quality selector for different HP settings just like we do on the 800's. Some updates in intercooler technology are being tested on this sled right now and we are very exited about the results we are getting out of the "baby 6". Over all the 600 is a great package in stock, mod, or boosted applications!

I think it was HM turbos that had the vacuum setup design in the charge airbox for low rpm. This diaphram ,so to speek, would open when the engine pulled a vacuum basicaly eliminating the lag feeling.
So their reliable, linear power delivery, can make just as much power and are a blast to ride. Is there a big difference in the torque output or can it be made to spool up fast enough that its a non issue?
Hmmmm....damn it!!! Now you have me thinking about my '12 RMK Carls 660 sitting in my garage. I should wait another year and snowcheck a new stock sled and then add the turbo.
I'm interested in the Vi-Pec stand alone fuel mgmt as I didn't have very good luck with Dobeck boxes. Is this something that needs additional tuning on the customers side or once set, it's done?
Testing for different elevations? Have you tested this setup for sea level elevations with the Vi-Pec?
Any video's of the 600 turbo?
Is this setup for the 600 good enough to essentially cover up the gauges for a day and just ride or do you need to always keep an eye on the vitals?
Curious to hear your thoughts on turbo'ing the 600 vs 660.
To my understanding the way the vipec works u dont need guages id have them just because i like to moniter my motor. And yes from talking with shane it will run from sea level to 10k believe its going to change the industry i wondered why it took so long myself
