how fast is top speed - Page 2

post #31 of 40
I'm with bumpfreaq. 60-70 mph in a car seems slow after skiing at +40mph.

60 to 70 mph seems slow in my Caprice almost all the time, not when going sideways on an icy corner trying to squeeze between the car in front that just ran onto the shoulder and the oncoming traffic though.

I often feel like I'm still skiing when I leave the ski hill; I try to get the same g-forces, but the car just can't do it.

It felt so slow I brought them in to get fresh wax (On bigger hills I have felt these skis go fast).
We set a speed trap on Starting Gate a couple of seasons ago using two beams on our race timing system.

The fastest NG racer (10 years old) got up to 87 km/h.
One K2 boy (14, in a speed suit) reached 104 km/h.
One of the coaches hit 110, jacket off, no speed suit, no race prep for his skis.

Pretty much matches my results.
How fast do you figure straight-lining Spectacular would be on 208 SGs with about 1/2 to 1 inch of freezing rain underfoot (batteries in GPS were dead). It only felt fast after I hit that one bump I couldn't see through the iced-over goggles.

I brought my GPS on one day for some speed runs. I was on 184cm GS skis and my buddy had about the same. We both stayed on edge carving longer arcs and managed to hit 100km/h, or about 62.5mph. And this was only on a blue run.

We made sure there were no other skiers on that hill when we did our runs. Much safer to stay on edge as well. At that speed I felt every little ripple in the snow that I could have just ignored at slower speeds.

I've had race stock slalom skis which are more versatile than GS skis, but I think its safer to be on the longer GS skis for higher speeds.

I remember falling during one fairly fast run a few years earlier. It seemed to take so long to finally come to a stop. I felt I could only try to relax and go with the series of bounces and that it would be more risky to try to fight it. I was quite relieved to find that I wasn't hurt when I stopped.

For most of my skiing I like to ski steeper terrain or bumps at much slower speeds.

Fast!!

I've never measured speed on a rain day, but it sure feels fast with some rain over a firm base. Push right off the chair, skate the approach, and head straight down the pitch on Spec & you'll really be moving. Making a comparative guess based on the layout of our measured trap on Starting Gate, I would think a top end of 120 km/h is achievable.

I'm told by folks with more speed camp experience than me that speeds beyond 120 are not easily attained without speed suits & speed skis.

When I've done speed traps, it's been on days where the snow is not too hard & icy, and on tracks chosen to put a bit of a limit on terminal velocity for safety considerations (I'm working mostly with kids).

Top speed is currently is 251.4 km/h (156 mph), achieved by Simone Origone. That's 6 mph faster than a Boeing 737 needs to take off.

BTW, I purchased a Silva Tech ski speedometer yesterday for under $90, new! I will finally be able to get a reality check....or a surprise. :

if only it wasnt a joke..

let us know how it works

Me i never ski faster than 25mph because to go faster than that is impossiable

As for "best at speed" label, it generally means that you need either weight or momentum (since momentum is speed x weight, speed is key here) to make that ski respond to your inputs. My understanding is that 25 mph or higher is generally enough speed. If you need more than that to make a ski behave, you have the wrong ski (unles you are a racer).
or on Legend Pro. Or skiing an actual mountain.
