If I were in the position you're in, Anders, I'd get in touch with Pork Pie. He's an aero specialist (as well as a damned good photographer) and might be able to give you some tips and help. He lives in Heilbron, Germany, by the way, so I have no clue what language you'll share
Best wishes and have fun with the bike.
That is a good advice, for now I think that sorting out the most fundamental errors here in the build thread will do wonders. When the time comes to rebuild the bike fairings completely I´ll send him a PM, but not until I have done some more high speed runs with the larger engine so I know how much extra space I´ll need for everything.
At the moment I am gathering parts and making the sand casting patterns for the compressor section so hopefully I will have the front end made by the end of this winter.
It will have twice the power of the engine I use now so 300hp or slightly more is the goal.
Here is the new engine case next to the bike, it is 30cm in diameter so I might need to modify both the chassis and fairings in order to fit everything.
It will take a couple of years to finish so the plan is to race the bike with the old engine in the meantime and try to figure out how to make the fairings as slippery as possible, if this engine is capable of 300km/h on the mile the bike will be a serious contender with twice the power!
Another method for finding Frontal Area. Complete with battle dress (leathers and helmet) sit in the tuck position on your bike,, have a friend using a dress makers tape measure around the extremities as viewed from the front,, this will give a "circumferance", do the maths,,,
Anders, Enjoying your journey mate,
Another good idea for measuring the frontal area, it seems I have to bake a cake to trick a friend to drop by some day.
Anders, a couple of "lessons learned" are posted in my build diary. They might help you.
Very good lessons, I´ve learned them the hard way with a couple of earlier engine builds so I try to make everything as easy to work with as possible. I can remove the engine from the frame and take it apart completely in less than two hours if I need to, one of the earlier kick sled engines gave me a head ache just from thinking about taking it apart...
Cheers!
