It looks like there are hotels in the area, and I'm sure that an airbnb could be planned way early.

The first thing I said was "The winters must be too long there"

and also that I have to bucket list a trip to sweden for speed weekend on a frozen lake.

if you also fall down the youtube rabbit hole one of the test videos shows he has half and full throttle.
I think just to keep from annihilating people at the start line with full throttle.
I assume just by controlling solenoids to injectors.

I think they use propane.

But don't get me wrong - Pulse Jet > not pulse jet.

I think they do it just to be in a jet class.
they're doing it like bonneville and setting ice speed records.

Yes and they are the same drink or sober! We used to call them European jamaicans at work. We had a ton if swedish made equipment and the shit would be hitting the fan over here, and all you would get out of them was "it's all good" and "soon" for a timeline. They made good stuff and got it handled but they are a people of few words. It was hilarious when they would come in to give presentations, 1 sentence a slide with their back facing the room LOL!!! My kind of people!

The pulse jet racing is awesome!!

107-113 actual speed on a 'built dyno tuned turbo' (aka, racing sled), yeah I'd believe that. But 130 on a 'non-racing' sled, nah.
