I remember when I first saw this video 12 years ago and watching it today is still awesome, if you need to start an avalanche just ride this thing through the valley.
It actually is 750hp. It's a Nitro Methane fueled drag motorcycle engine. It just could be more efficiently clutched and geared. Putting 750 to the snow and gaining traction is no easy task.
yes! top fuel dragster nitro nos gas racer pro comp extra boost turbo double supercharger exlusive head gasket trippel handlebars lyxury seat and a big ass engine
Until you set the front end at 150 miles Per hour on your way up the hill and go tumbling and yard sale your stuff all over the damn Mountain eh’..... ....... bummer😕 And at the same time F yeah!!!
I read this report/story in one of the motorcycle magazines here in the United States in 1989. I still have the issue somewhere, it was either motorcyclist, cycle, cycle guide, or cycle world. I subscribed to all four of those magazines at that time. ..every car manufacturer from Chrysler all the way down to dahatsu (spelling??) was working on and had running 2cycle powered automobiles. The Toyota was actually one design that checked the engine crank case oil with a dipstick. It was not a total loss oil system.. every manufacturer had cars just about ready to go into production. Overall their findings were, they could get twice the horsepower per pound from a two cycle engine compared to a four cycle engine. Which meant, they could have the same horsepower with a two cycle engine that weighed half of what a four cycle engine weighed, or, they could make an engine that weighed the same amount as a four cycle engine, and have double the horsepower. One little thing prevented two cycle engines from powering automobiles. The EPA. It wasn’t completely because of tailpipe emissions. It was because two cycle engines in these automobiles could not pass emissions once the car had a proximately 100,000 miles on the engines.. any mechanic that has experience with two cycle engines, knows that the engines pistons are the first things to go out of spec because of marginal lubrication from diluted lubricants.. I understand that a film of oil is only so thick, and I understand that the low compression of a two cycle engine does not burn the oil ..I am sure that today, they could develop materials they could survive in a two cycle engine combustion chamber, the piston, the cylinder walls, better than the materials they had in the late 1980s when we were close to having two cycle engines in cars.. I raced to cycle motorcycles years ago. I actually won six road racing championships, and 2 National road racing championships using 2 stroke engines.. I had a few Engine seizures on the track and on the 2 Cycle syreet bikes I rode at the time on the street. Pistons in my road racing machine, the factory recommended changing the pistons every 600 miles, and the crankshaft every 1200 miles.On my dirtbike’s in those days, you would hear the piston rattling, and engines would get hard to start once the Pistons clearance in the cylinder became too large to keep the rings square in the cylinder to maintain compression enough to keep the engine running or to permit it to start.. on my dirtbike that was the first sign you need a new piston, it was hard to start when it was cold. Water cooling masked the sound of piston rattle somewhat, it also increase the life of the piston because the cylinder did not distort The way that an air cooled cylinder distorts because of uneven airflow carrying the heat away, and the cylinder being cooled differently in different parts like the transfer ports ran cooler than the area around the exhaust port.Crank seals were critical And lived in a hostile environment and became brittle. Losing their ability to maintain crankcase compression. So, a 2 Stroke St. bike engine pretty much needed a new piston/bore job/crank seals at 20,000 miles.. at the same time, if you checked the thrust washer ware on the crankshaft, you would find that would be out of spec , And the crankshaft being ball bearing or roller bearing or needle bearing, they would need to be replaced while you have the engine apart doing the top end job. so sure two strokes make a lot of power per cc, but they don’t last as long as a four cycle engine. They also don’t like to cruise at. steady speeds on the highway. They tend to surge as the RPMs approach reach peak efficiency (power band)make them want to surge...I suppose a heavy fly wheel would tame them somewhat.. saab had 3 cylinder Two stroke engines in their cars. I myself had a saab sonnet, but it had a V4 fomoco four stroke engine... The three cylinder two stroke saab did not have and oil injection pump system. The driver of the 2 stroke saab had to wait till the car needed to take at least 10 gallons of fuel. Then pull into a gas station and put in a small container of two-stroke oil into the gas tank, and then pump in only 10 gallons of fuel to mix the two-stroke oil with gas..I would not like that myself. I never liked pre-mixing oil. On one of my race machines that I won all those championships with, it had a oil injection system that I never removed like some of my fellow racers did. I did lean the pump down So that the oil pump did not reach full stroke until the carburetors were at full throttle. The racers that eliminated the oil pump system and went to pre-mixing, tended to put a little extra oil in the fuel, and unwittingly !leaned their fuel mixture out which caused overheating and seizures because they did not realize that they were leaning out their jetting when they put just a little more oil in the gas for premix... in those days, some of the manufacturers recommended a pre-mix ratio of 16 to 1 or 20 to 1. It’s a wonder those engines ran at all with their very weak ignition systems and some of them using Champion spark plugs. Fouled spark plugs were very common.. I had many two-stroke motorcycles, I prefer them riding in the dirt. But I would not want to have one in my street bike. But it appears we will all have to get used to electric powered cars. And we will be talking about how much we miss gasoline powered four stroke cars when everything is electric in about 30 years
@kartz4fun It's a four cylinder supercharged Kawasaki motor detuned to 750HP. The motor is out of a drag bike, where it made about 1000HP. It also runs on 90% nitromethane.
im from the south and i no absoutely nothing about sleds but i no bad ass when i see it....wow....that thing is freakin insane....awesome vid and sled.....
My Big block 650 Wildcat used to shredd belts too from the torque just like cattail fuss in your mouth - under the hood made a major mess -the end of the day you could`nt bend your arms from being stretched from torque can`t imagine what that would be like .
That thing is crazy, pretty brave to ride it, hopefully someday someone is crazy enough to point it up at Turbo Hill here in Revy, Sure hope I there for it
this is only at 1/4 to half throttle hes just testing it to see how the belt will hold and not slip and what else he needs to do to it so it runs solid
Pretty cool . But in my opinion snowmobiles are going in the wrong direction in advancements . Way way way to big, long, heavy and way to wide for trees, big rocks and tight sections. I guess if you ride on well groomed trails, tracks, flat lakes and smooth rolling hills a sled with 5000 hp, ten foot long weighing 900lbs works real good.
Yep you are right, I still love my old 1969 Ockelbo 300. It has a sach 290 engine pushing out a massive 25 hp lol. Still it's a small machine, nimble and fun as hell.
@kartz4fun you are probably right, but i know how hard it is to make power out of a 4 cylinder let alone 2. i don't know it is a big number for such a little engine
