Sorry about the multiple replys, but I can't seem to get my machine to send more than one image at a time.

Hey andrew, I split the topic so people can chat here about your new project without getting the PIC/PLC thread off-topic. I hope you didnt mind
Also, there isnt a way to upload multiple images in one post right now, but that is something else I will be looking into. The only way to do it is using an external image host (like imageshack.us or photobucket) then copy the BBcode and paste it into your forum post. Kinda a bummer.

Are you working from an existing bike frame or did you guys start from scratch?

What type of clutch mech are you going to use. Looks like the sprokets are lined up perfect. Is this one of your engines?

Hi Ernie

No clutch required :-) its a freepower equiped bike like my first one , just add some throttle and away you go , same as an automatic gearbox equiped car , it should produce ~150 RWHP.

The "engine" will be the 10/98 gas producer I'm developing , just a matter of plugging the exhaust of the 10/98 into the inlet of the freepower scroll , the ~8.5 inch dia freepower turbine wheel is the 4th stage turbine wheel from an Allison C20 engine .

The transmission /redux is another item made up by Andrew and I .


Cheers

Hi Guys,

The perimeter frame is basically a stock unit, but because of the removal of the IC engine, I have to try and make it a semi cradle frame as well as try and make a dummy pick-up that incorporates the standard IC structural points that the engine used to provide.

The good thing about this frame is there is still some scope for structural improvements, as we don't really know how the monstrous torque John's motor generates is going to behave with the configuration I put together

I still curse John every night before I go to bed, for making me enjoy his first proof of concept bike enough to assist in developing it further with him.

I would make one comment regarding John's statement about "just add some throttle and away you go"...my experience of riding his proof of concept was not so much "same as an automatic gearbox equipped car" but more like warp 9 on the Starship Enterprise. Not like any automatic car I've ever driven!!!

Really nice project, I´ve heard from John about your build and it will be a great bike once it is finished. Has the engine arrived by mail from John yet?

Hi Anders,

Sorry so late getting back to you on your post...so bloody busy at this end

Not a lot of progress so far as regards bits on the bike, but have done quite a bit sorting out the associated problems for fitment.

Will post some more pics in the New Year.

Any thoughts..?

Hi Andrew

LOL......B1 is a skinny kid compared to fat old Frank :-)

Not long now until you have the best turbine bike in the world.

Cheers

Have you guys given any consideration to FOD protection? OK, I admit my bike is slightly smaller but I'm WAY ahead of you guys and all I can say is the part where you test ride and inspect and test ride..... oh dear have to test ride again! And I only have like 8 horsepower! You guys will be riding rocket ships! Hope you're stocking up on fuel! Anyway, the last inspection in my highly advanced development program revealed some FOD damage, the leading edges of the inducer are scarred but I see no material loss or feel any vibration so I'll keep running it until I notice a change in the bearings and/or fuel consumption.

The original air intake was made from dryer hose and picked up the air right behind the forks below the steering neck. I made a new intake housing out of sheetmetal. I have it going up between the forks over the front fender and I plan on making a bellmouth that will hopefully blend into the body work. The tires on this thing are sticky and like to throw anything they run over all over the place so I'm hoping getting the air intake further out will help.

I'll make the opening as big as I can and put some open cell foam or mesh in front of it. I also used a trick we use on the industrial lasers to control contamination- slow down the air in an area that's sticky. In the lasers the gas flow slows down just outside the blower where it enters the bottom of a heat exchanger, we put vacuum grease there to act like flypaper.

First off I made the intake housing as big as possible near the compressor inlet. I had to make some holes in sides of my new intake to get to the mounting hardware, I went ahead and made 2 huge oversize holes in the side and also a huge hole in the bottom. It's real easy to get to the mounting screws and when I'm done I cover the holes with some really sticky tape. Now the area near the compressor intake has low dynamic pressure and crap in the air slows down and gets caught like flies in flypaper. And it's easy to peel the tape off and check how well everything upstream is working to keep crap out of the air.
