i wasnt there but a buddy of mine was just talking about how they got a 95? i believe thats what it was, mxzx 440 going 147 mph in 2 miles, for gearing i think they ran something crazy like 30-38 and for the longest time all they did was blow belts so one of them came up with the bright idea of slowly laying on the throtlle until the one mile mark where they actually can grab her than she slowly picked up speed to 147 which was recorded at the 2 mile mark on bare ice

ummmmmm i dont thnik so. Thats like getting a stock honda civic to do 147mph. Its impossible

he has vids of it, on 8 mil cam so will see what i can do

with some insane gearing you could probably get some good top speeds, I dont know though. Must take a while to get her up to any sort of speed though!

There was a 77 srx 440 held (and possibly still holds NSSR world record) 101mph in 1000'

77 arctic cat z 250 went 94.7mph in 1000'

Either way those old sleds were moving!!!

my dad ran on the grass back in the day. A 79 skidoo 440 snow pro. on the grass he ran 101mph in 500'

Jacques Villeneuve hit 110 mph 2 years ago with his skidoo champ 440 at the CPTC ice oval race track in Beausejour Manitoba, i saw it for myself.

a 1999 polaris 340 at 110 mph.....i was towing it with my rev 800

Dads exagerrating.
World record 440 only pulled 92 mph in 500 ft. on grass.

101 is a pretty good mph for 660' on ice though.

Fastest 440 I've seen was a MXZX 440 with a turbo 122 mph. 1500 ft. pull.
Stock '99 ZR440 111 mph.

I also agree with you Rosco...I'd say thats definately exaggerated!

Terry Wahl on his Champ 440 at the CPTC got 111 mph outta his champ. Of course those arnt even close to being a stock 440.

in 1998 ,dan boyle from maine turned 109 mph in 660 ft at presque isle me on his 440 mod.it was about -15 fahrenheit that day. dan ran that sled all the way up to the open class before finally being defeated by rheaume rodrique on his1000.

5.8 secs,110 mph,2001 world series,660ft

I am pretty sure the nssr speed record on a 440 Open Mod ( Dart???)Rotax Sno Pro motor with a 13" speed track is no more than 125 mph . Thats with a 270 lb sled and the best Aero package available. So thats pretty much reality unless your going down a Ski jump. MMR

Our Drag sled bone stock 1999 zr440 snopro 99.9mph in 600' we won a-lot of rewards that day very fun sled! :beerchug:
