Nice numbers, 155 kph sounds too mad already, do not mention 200 with sledge ;D Hope to see your bike next year, running into 200 kph .
Cheers Sven

According to my friends 155km/h was very uneventful, they are both bikers so I don´t think 200 would scare them.

Lots of work to do and only 11 months to next Speed Weekend!!! I´ve spent lots of time the last weeks thinking about what I need on the bike, where to fit it and in what order, I need to do this right the first time so I don´t paint myself into a corner. The fuel tank and the oil tank will sit under the engine with the fuel under the gas producer and the oil under the power turbine section, 15 liters of kerosine (I picked up a 60 litre drum of Jet-A1 yesterday) will last 10 minutes on full throttle which should be enough. 7-8 litres of oil and my large Mocal oil cooler should be enough I think. I have also been thinking about the intake air box, one cubic metre of air each second is plenty so it must be full flowing without letting any debree thrown from the front wheel reach the compressor inlet. I´ve got an idea so stay tuned for updates as soon as I have bought a sheet of 3mm aluminum. A lot to do indeed, first out is to fit the pumps and the oil cooler to the frame! Cheers! /Anders

Hi Anders
Some nice looking bits and pieces to fit :-)
Inlet air certainly needs to have " ram compression" factored in at the speeds you'll be doing .
Oil tank will need baffles if fairly shallow to prevent uncovering the pickup during accel/decell loads .
LOL........my butt is already hurting looking at that seat ;-)
Cheers John

Yeah the intake need some work, I will make an aluminum air box open on the top and direct the air from the air intakes toward it but leave a gap so the engine can suck all the air it wants when the bike isn´t moving fast enough to get ram air compression. I made a crude rig to measure the amperage draw from the pumps today. They do need some juice since I got a total of 50A draw with 10°C oil temp, at running temps the oil will pump easier but still... After I had managed to get oil all over my best jeans I temporarily fitted all pumps etc to the frame to see if they would fit the way I wanted them to. It seems like I will be able to fit everything and still have plenty of room left for an air box for the intake, great! The placement of the oil filter is a bit...original...... but it will work fine, as a small bonus the ram air will help cool the filter a bit. The oil will be very hot after a while so I need all the cooling I can get for it. My 24 row Mocal oil cooler will have a tough job ahead of it. Then it was the battery issue, I have been thinking a lot lately about lithium batteries but they aren´t exactly cheap when you get up tp 30-40Ah. When standing in those thoughts I just so happened to look at the battery I used for testing the oil pumps, what if that would actually fit on the bike? Yes! I couldn´t even imagine that a car battery would fit but since I didn´t put any oil pumps on top of the gearbox as I had planned before there was plenty of room for the battery. Sometimes luck is on my side! The bike will be very lean, great news for the aerodynamic department in Johansson Speed Development Inc. *LOL* Cheers! /Anders

Hi Anders
That battery spot looks like it was made for the job :-)
Yeh , every square centimetre of frontal area you can save will be worth while at the top speed, slipperiness is the name of the game , weight isn't much of an issue .
She's coming together rather quickly now :-)
Cheers John

Hi John, I was surprised that it fitted at all, some heat shielding and it will be good to go! I visited a friend on monday evening who is building a funnybike with a turbocharged hayabusa engine, right now he is buiding the fairings for it and damn what a job to get it perfect. I have to make sure everything sits exactly where it should be before I start making the "real" fairings since I don´t want to do it all over again later... Yup, some mounts for the pumps and stuff and then it is time to start building the tanks and intake air box. Solving the battery issue this easy was great, I thought it would be a major problem to find batteries bowerful enough that still would fit the frame. Cheers! /Anders

Hi Anders
Yeh , streamlining is a specialist art , but well worth the effort , back in the early 1960s the motorcycle land speed record was held by a 650cc Triumph streamliner at 225mph -362kph, now that was some achievement for the times , but basically all down to the slippery body work ......the engine, somewhat detuned, then became the Triumph Bonneville we loved so much in our road bikes.
Cheers John

Thanks! (I had to Google that one) in Singapore, being multi-cultural, multi-languages, we always say 'add oil! add oil' as a literal translation of this..
加油 or jia you means all the best! or work hard!
or gambatte in japanese.. same meaning...
so in a baseball game, just go "WOOHOO! [team team name] !!!!!!! YOU CAN DO IT!!!!!"

Good job, looks very compact indeed. Sven Thanks Sven! Hopefully I´ll fit everything inside the fairings.

Cheers John Damn, that fast? I will have to think twice before building my fairings then, with almost 200hp wet (guesstimated power with water/methanol injection) I only have the fairings to blame if it doesen´t haul ass. Hopefully my old -67 Bonneville will teach her a trick or two during all the long nights standing beside each other in the workshop. ;D
