Must be spring.

NO CHIT apex with a 174 and that?????? Either that or the smoke at the bottom of the hill ain't comin from a 2 stroke!!!!!!!

163km/h yesterday on the ice field. hard pack snow, apex 162, 17lb, 310mcx, stock gears, 10,250 rpm.

can someone tell me where me what rpm my rev limiter should be at? and is it adjustable?

 

[zebiraross]

rev limiter is 11,200. You can't adjust your rev limiter unless you use RB3.

I was on good set-up spring snow. It was a steep mountain though and at 10,000 ft. That being said I was suprised my 174 turned that fast as well.

 

[dcturbo]

WOW!!!.. My nytro bd 162. 71mph 18#s elevation is at 10,000ft..

 

[Thistledoo]

My MCX nytro at 12lbs on saturday was running 70ish mph in a deeper heavy wet snow on a good climb....at 6800ft and I was smiling all day long Cant beat this for april 26th

 

[Polarisrocks]

Saw 95mph with it at about 19-20 lbs saterday. 162x16x2.5 The sled was rippin!!!!

 

[apache]

what rpm should my sled be at at full throttle? I'm only getting 10250rpm with my clutching. am I missing out on power?

 

[JSCC]

At 12 mine turns around 85-86 with the Mav in stock position. Hard setup snow. 9500'.

 

[Sapling-Thrasher]

Apache, Clutch for 10,500-10,600. The power is so broad you might only be missing out on a small bit of power though....

 

[zebiraross]

At 12 mine turns around 85-86 with the Mav in stock position. Hard setup snow. 9500'.

Jed, what speeds did you see at Fairview? I thought you were 107? I know that was on higher boost then 12 though

 

[WesG]

apples and oranges

I think we need to split this into uphill drag speeds and real snow hillclimbing track speeds.

JMHO

Uphill drag speeds just over 90 mph @15lbs
Real snow climbing 65-75 mph @15 lbs (loaded up on a steep hill with tonnes of snow ie not racing up some packed runway).
apex
2860
170lb rider
Stock mav 162 turned around.

 

[Nytroman]

Nytro MCX 12# stock track, hard pull heavy snow arking out at 95 to 105 km
climbing hard pack as fast as 155km

 

[JSCC]

I agree, speeds under good snow conditions will be different. So we just need to post what the conditions were like when we were testing.

Zeb, while I was testing at Fairview I was seeing 107. I never looked once we got back to race bowl. I would bet back there it was far less. I had to remove some helix back there just to pull the hill.......need more boost,lol!
And yes, that was at 17-18lbs.
