Hi everyone, 24 and 25 February is the date of next years event.
the big news is that Kurt Anderson from USA is bringing his superduper Hydrogen Peroxide Arctic Arrow Rocket sled , to attempt a new world record of at least 250mph.

Sofie the sugar rocket will be making a comeback in 2017
complete with a graphite throat that cant melt , an afterburner, and , but not shown here, two proper scooter skis at the rear

I just heard from Glenn, that there will be live streaming from our Speedweekend.
Keep an eye out here for updates which website we will stream to.

Super! I'm looking forward to hearing that, good luck to everybody! :cheers:

Sofie the rocket is ready for action

You've got some evolution going on there Ellwood, :mrgreen: don't forget to hook us up with some video.
Sid.

Dang it, I'm not going to be there. I want to - and every year John Ellwood gets in touch with me and offers all sorts of inducements -- if only I get to Stockholm. Damn, it costs about one point three tons of $$ to fly to ANYWHERE from our town, so here I sit, wishing I could be there to give everyone a front row seat. Maybe some year the lotto ticket gods will smile on me and you'll hear me from the ice.
Best wishes for a safe and fantastic event. :cheers: :-D :-D :cheers: :-D

I think things are pretty wound down now, the Artic Arrow had a 141 mph test run, the "Bonneville Bee" made a 108 mph pass, very spotty info available, most of it on Facebook Landracing.se
-
the Arctic Arrow did 206mph
a 1000hp Audi car did 208.125 mph
Pawel from Poland with his Hayabusa turbo motorbike made 196 mph i think. I havent seen a result list yet
my little Hybrid rocket sled Sofie got a plug in the (new for this year) plastic cartridge, which led to a burn through, in the rocket pipe, upwards and through 3 safety plates. luckily i had 4 safety plates all in all, which saved me from getting fried

the slight glow under the sled is showing the burn through

then i had to do a bit of modifying , to try and get her to fire up at the rear end instead of the front, but she wouldnt light up proper - just blew the flame out when i tweaked on the NOS

Here is the Mobacken Racing story, we ran our twinturbine jet kick sled for the third and most likely last year. We´ll build a new chassis for the engine that is better suited for speed. :-)

You are absolutely crazy.... in a good way....glad you survived your tumble in the snow...
from the first picture :-o I was trying to decide if it was warm or cold.... but I noticed everyone else seemed to be in heavy coats
:cheers:

Do you know what caused it to drift to the left? Good thing you (or Olof) weren't hurt.
Regards, Neil Tucson, AZ

Don't know how to say Knucking Futs in Swedish but with the help of Google translate: Nävla Jötter :-o Naaaah, just not quite the same! :-P :-D
You guys are on that thin line between ingenious and devious! Keep it going! :cheers: :cheers: :cheers:
Did some work with Sandvik in years past and always enjoyed my trips to Sweden! :lol:

Thanks a lot guys! :-)
The drift to the left started when Olov shut the engines off, when the jet thrust disappeared the kick and driver caught the wind in 130+km/h and the unsharpened sled runners started sliding sideways on the hard ice track.
Three out of four of all jet kick sleds ever raced at any speed at Speed Weekend ended up crashed, we start to understand why now. The runners are very sensitive to the quality of the track and with bikes and cars tearing up the track with spiked tires it is almost impossible to run a kick sled without hitting one of those tire ditches and being thrown off course.
A new and more suited chassis will be built for the twinturbine engine for next year, so stay tuned! :evil:

There are a couple of photo albums up on the Speed Record Club's FB page which may be of interest of Kurt Anderson's bid to be the fastest ever on ice and the Arsunda event in general. Fair to say this is an incredible event to witness with a unique range of vehicles both wheel driven and thrust powered, very well attended and superb organisation, see you next year!

The rut chasing problem you ski guys are having is common to a sled (snowmobile) with "single skeg" ski's in rutted trails where they want to follow an existing rut. When I'm going to ride mainly trails I switch to a "twin skeg" ski & that totally solves that problem. I've seen guys hauling a$$ on flat trails where a single skeg has taken the sled right out from under them. Due to the size of the ruts you're having to deal with there, you might need to build some super wide ski's to keep you on top.
Something else you'll want to look at is steering geometry. Modern sleds are set up with positive Ackerman to help them turn at low speed but that necessitates a lot of rider weight shift at high speed to prevent them rolling over. In your situation I would be inclined to zero the Ackerman to the length of you vehicle, that will also help prevent a hunting problem.

Thank you very much for your suggestions Sid! We plan to build a dragster style ice yacht with skids to get some kind of steering, the added length will surely improve the handling and make it a bit less sensitive to the grooves and cracks in the ice.
I´ll look into the Ackerman stuff you mentioned, good stuff! Please do explain how it "will help a hunting problem", has auto correct gone mad or is something lost in translation that I don´t get? :-)
Cheers!

John Ellwood has sent me a CDrom of pics from SpeedWeekend on Ice, and I'll get 'em up here for your viewing perversity/pleasure right away quick. Your chance to see what you missed will be here soon. Thanks, Jon :cheers: :cheers:

Its all thanks to mark Thomas again
Heres hoping a few more of you Yankees will be coming to visit us next year. i think the standard of our builds is getting quite serious now, and our record speeds have come quite a way since the first race way back
-
In re: The pictures. I asked Bob Clancy how to load 'em, from here - and report that he has talked me into admitting I'm a doofus and that he can do a better job of it. So I'm mailing the discaroonie to him and he'll get it up there pronto.

The SpeedWeekend on Ice photos are now posted. If nothing else -- find 'em by following form the home page of the site, which you want to visit anyway to see the story about
The Flatfire.
Go to the home page, kids!

Aaaaaaaaaaaaargh, photobucket has updated something, and seems to be holding me to ransom for 400 dollars to share my pics to 3rd parties. anyone know how i avoid paying them ?
-
Yep, move your pics elsewhere and hope they don't do the same shit :x
