102 MPH @ Keystone on 195's?

post #1 of 27
Thread Starter 
I would really like any input you guys had on this one. I have heard a claim that someone was going 102 mph on Frenchman @ Keystone. To me this seems to be to tall a tale to beleive. When I expressed my disbelife I was told that he was on "195 Kastle's with a race tune". To me 195 Kastle means womens GS, not a speed or even a DH board. What do you people think? Could this be true?

not true

I don't think the skis would be that much of a limiting factor - my question would be whether that run is steep enough to get up that much speed. 70 or 80, maybe, 100 seems unlikely.

Perhaps they meant Kph?

Only with a 3/4 race cam.

An old college friend of mine was a dedicated KL skier: to achieve the grail of 100 mph or 164 kph, you need KL (kilometre lancee) boards, speed suit, ridiculous fairings, pointy helmet, funny pole and a serious screw the torpedoes outlook on what might be a very short life. And get yourself to a super steep specially prepared piste that is basically ice.

So, no, the odds are against it.

This is a job for Physicsman! Terminal velocity aside...At KEYSTONE???? I seriously doubt it, and its not official without a speed measuring (timing) device. Anyway, for speed skiing, do these look like 195s to you
post #7 of 27
IIRC, drag increases with the square of velocity. To get to 160 mph you have to be dropped out of an airplane or jump off of a building. I doubt doubt doubt it.

There is no way frenchman is steep enough. It's basically a few blue level drops that feed into a green trail merge at the bottom.

100kph, probably, 100mph no way.
post #9 of 27
Sure it wasn't 10.2 MPH? Now that i can believe. By the way how much were you guys drinking at the time this story came Up?

Thanks for the replys. I did not think is was possible, but I wanted to get some other opinions. He was pretty emphatic that it was MPH. I have trained DH at Whiteface on 215's, and have driven the Autobahn and know the difference between fast and holys#$@t fast.
As some backround, what are the average speeds at a WC DH? Top speeds?
post #11 of 27
I heard the peak top speed at Birds of Prey is in the neighborhood of 90-100mph. Was watching it but wasn't really paying attention to the speed.

Bob and onyxjl are right. It's KPH. That's only 62.5 Mph and that's fairly "easy" to hit. I've done that when I used to work in NC on a mountain that isn't know for it's steepness. I hit 50+ mph on my road bike on a 10% grade, so I'm sure that 60ish on a 20-30% grade wouldn't be out of the question.

The fastest World Cup DH course is in Norway with high speeds in the 90's. Kitzbuhel is also up there with speeds in the high 80s
post #14 of 27
I thought they said some top guys were hitting 98 mph in the Wengen training runs too. I might have it confused with one of the other recent downhills though.

Regardless, 102 MPH is rediculous.
post #15 of 27
I've never skiied 100mph. However, I did hit 178mph on the Autobahn in a BMW a few years ago. Yes, BMW's go that fast.

This is correct. they clocked people in the speed trap in the 95-98 mph range in the Wengen DH training runs. You don't need all the aero fairings etc. That said, you do need a hill a whole lot steeper than Frenchman, and you probabkly need to be wind tunnel tested to get a proper tuck to allow those speeds.

By the way, 160 mph is not only possible in places like the Les Arc speed hill, but it's proven. I'm not sure what the fastest speed is these days, but it was in the 150s a decade ago.

Oh, and "terminal velocity" is a farce. It's based on sky diving in the standard sky diving position (whatever it's called), and wearing a loose sky diving suit. I watched a speed sky diving competition on OLN, and with the right rubber suit, and a head-first, arms back positon, they were hitting 300mph (or dang close to it).

Interesting...with the right rubber suit I guess you can do a lot of things.

That cracks me up. I wonder what they will think of next.

Terminal velocity applies to anything where forces causing and opposing motion are in equilibrium. If a skier is going down a constant slope in a perfectly rigid tuck where ski/snow friction remains constant then there will be a maximum velocity where gravity and friction/drag components are in equilibrium.

Right, I think he meant that it was a fallacy that that figure was 160 mph in all cases. I'll buy that, how much drag you are carrying obviously plays a role.

So were you screaming down the steepness of Switchback or maybe white lightning? Get brave and tuck Sock-em-Dog.

The speed skiing course at Mt. Hood Ski Bowl will let you hit speeds of about 130 maybe a bit more. But these guys are real speed skiers with all the gear, boards, etc. Here is a picture of the course http://www.speedski.com/MtHoodOregonTrack.htm

While the caption says it's at Timberline it is at Mt. Hood Ski Bowl. I skied this years ago on 210 GS boards and never got over 80 (you need the special super fast chipmunk suits and helmets and leg fairings blah, blah, blah.

I vote urban legend.

Now do I think an untrained bozo with a speed gun could get the gun to register 105 while "recording" his buddies run - yeah without a doubt!!!

That, ladies and gents, is what a speed skiing piste looks like. Yes,you go to the top and point them straight down.

Men's record is 155 (248 kph) and wome's is 150 ...mph.
Its only been in the last 12 years that they have cracked 130 mph (about 220 kph). 120 mph was first cracked in about 1982.

That makes me respect the Bode Millers of this world a lot more in that they nearly touch 100 mph on the steepest DH courses and then turn. Bode is also dressed in a special suit, etc. But some yahoo claiming to have cracked 100? Nope.

N. American speed record is 129 m.p.h.
(set by Franz Weber at Silverton in 1983/84)
I remeber after speed skiing stud Jeff Hamilton ( who has hit 150+ in france) moved in next to me in Basalt, CO, in the late 90s he helped get a short speed track at snowmass going. ( 3,000 ft long and 1,100 vertical if you want to compare that to Frenchman) They had Recreational Races located on "Slot" run off Sam's Knob Peak. The race entry fee, included instruction to cover the basics.
There were a lot of people on makeshift equipment, usually old race skis 200+
from the website:
As speeds increase, the start will be moved further up on Slot run
First run between 35 - 45 mph
Next run, if certified from 1st run, at 45-55 mph
Third run, if certified from 2nd run, at 55 - 65 mph ...
and so on

I cant find the postings of the speeds, but remember only the pros ( rubber suit et al) breaking the triple digits.

That's a good point. Either that or some hand-timed speed trap that was about 20 feet long.

102 mph on 195's ?

Sure, as long as they're 195/50 R16 V rated tires ...

On Skis? Perhaps SOMEONE could somewhere, somehow. But not at Keystone.
post #26 of 27
Having done 100 mph on a dirt bike and taken some pretty straight lines on 210's back in the day, I can tell you that in a good tuck on 210's maybe I saw 70 or 75. Definitely not anything approaching 100.

Are there any abandoned mineshafts around that run?

Here is a graphic of the willamette pass ski hill in Oregon.

I've skied this thing, but it had huge moguls on the 52 degree face. I thought the runout was a landing strip. They don't run speed trails there anymore, but the run is open for freeskiing!

Nay, he didn't do 102!

Lots of cool speedskiing info at
