2012 800 RUSH
Dan, what if I want to have a better performing motor. Do you have any options for porting or a different cylinder head? What about using someone else's products ie; Doug Ruth Porting and PAR cylinder head and CPI pipe along with your bottom end and pistons?
Thanks, Dawg
Wow !! You asked alot of questions in a short paragraph.
#1 I am a big fan of Dougs porting in Lake race & Full Mod Motors ( have not seen alot of his porting for pump gas trail motors. )
Translation of sled customer to performance shop is a very complex arena.
Most of the time the sled owner wants more then is possible given his or her situation, And most sled shops main goals are to improve performance. The amount of horse power the OEM's get out of the motors has gone up.
The quality of the fuel has gone down ( If you think about it, That is an amazing undertaking ).
It is important for the sled owner and the performance shop to get on the same page....... But sometimes they are not even on the same chapter.
The reason for this gets more complex every year, Alot of times the sled shop knows that the customer is expecting more then is possible with the amount of $$$$$ set aside for the project.
Indy Specialty for the everyday rider is not a big fan of porting or Big Bores....... Reason being ( Me the Owner Dan Turen ) Is 50 yrs old this year. And alot of our customers want mainly 3 things.
#1 - Above all.... dependability.
#2 - Easy of service, and they do not want to be put on the trailer by exclusive parts that cannot be repaired or exchanged at a dealer.
#3 - Bang for Buck.
When the big twin made its way into the market and the 3 cyl died off, I have stayed away from the performance side of the twin simply because
the gains for the money never mde much sense to me.
And the fuel injection systems Polaris has designed
prior to the CFI 2 has not given Indy Specialty a warm fuzy feeling.
Porting makes cylinder exchange unpractical so we rarely do it anymore.
Big Bores make motors to exclusive for the direction Indy Specialty is going in.
Indy Specialty Has been laying in the weeds for many years somewhat hiding from motors and chassis that just have seemed alittle behind unless the sled owner took charge and made the sled work for him or here.
Last fall I bought a new Victory Vision, And I must say Polaris proved to me that if they put their minds to it they can build some of the most amazing products.
The New PRO Chassis ( RMK, Or RUSH ) with the CFI 2 Motors has lite a fire in Indy Specialty and made Snowmobiling fun again.
Last Winter my local Polaris Dealer ( Red Wing Polaris ) Rerally push me to get a New 800 PRO R RUSH.
After the frist trip the Ash River in Northern Minnesota I was hooked on the chassis and really could not believe how much I enjoyed riding it. ( Were talking about a guy who only liked lake racing and bar hoping 40 miles a day max ) To a 50 yr old that now wanted to ride all day !!
I had the Big Windshield on it, and i had the side wind protectors on it, and all the storage bags......This machine was Warm to ride, had lots of storage, and most of all fun to ride.
My only disappointment was the top end speed, ( 99mph flat out on the lake ) The first trip I was schooled by a new 2012 E-Tech Ski Doo.
Next trip we did alittle work to the clutching, and brought a few extra clutches with so we could tune and adjust fast.
The first test ride out on the lake i knew i was onto something. ( 105mph ) The ski doo boys had heard in the bar that I had the 800 Rush running alittle better this year. ( There were 3 800r's this trip ) and a white 2011 they said was the fastest. We lined them up un a fire road and they drop an arm. The RUSH jumped the DOO pretty bad out of the ole and I never saw him for at least a 1/4 mile. ( I did over hear him tell his buddies he was catching me ) That is possible because that night out on the lake at extended full throttle for miles on Kabetogama 2 of the Doo's got by me at creap. My speedo was on 106mph on the max.
The next morning i made one more change and went for a test ride ahead of the group and saw 110mph on the max speed indicastor and could hold 108 pretty easy.
The Doo Boys rode with another group that day I and I never got my chance get back into the top end war.
This was with stock 22/36 gears with the biggest wide clyde windshield polaris makes.
All the ski doo's had the mid-high windshields, I refused to to go to the mid-high windshield. This windshield costs you a solid 2 to 3 mph on the big end.
The wrap up.
This summer I want to get my head around tuning this sled and learning the CFI2 on the asphalt. so we pounded this sled all summer 7 race week-ends of test and tune 5 to six hours every Saturday and race on Sunday.
1/8 Mile track ( 660 Feet )
This 2012 800 PROR went from 92mph the first week-end.
To Week Seven, To 115.8mph Back to back runs
Stock porting, Stock Bore, Stock Crankcase, Stock Stroke.
Altered OEM Pipe. Altered OEM Canister ( Stock sound ).It has a fuel management system on it.
It was running race fuel, as would any other Single pipes OEM 800 or Big Bore for that matter to run this speed. A turbo would need race fuel to run 115mph.
It was an eye opening summer to take a trail sled to numbers most people can't imagin. I will post the time slips.
3 time trials -
C. Miller my Step son is the driver.
Dan
) LOL!! That was GREAT !!!
