VW diesel mid-engine trke

[Fox]

For a few years I've had this idea of building a mid-engine trike with a VW turbo diesel and either a 914 5 speed or maybe a freeway flyer trans. As the diesel provides so much torque if I use the freeway flyer trans I can run 265/75/18 tires on the rear and I think gives me about the same final drive ratio for some really decent mpgs. I also like how many miles that little diesel lasts.

I read in Europe they race VW diesels and get 300 hp out of them. I also read that unshrounding the valves frees up some extra ponies with no reduction in engine life.

I am thinking about using 2 sets of foot pedals, clutch pedal on 1 side and accelerator and brake pedals on the other side. I am also thinking about a real cruise control system. I only wish to steer and use the front brake with the handel bars.

I have been wrestling with how to run a small size 15" car tire like a VW tire on the front for the extra miles it will last. I'm thinking something like a wide glide extended front end so as to accomodate the extra tire width of the car tire. My problem is the front wheel. Motorcycle wheels have the wrong lips for the tire beads on car tires. The only way around I've found so far is a $2000 custom made aluminum front wheel that is a motorcycle style hub and brake set up with car tire bead lips.

I'm open to any ideas that may help my project along.

Many bikes, like Goldwings, do successfully mount car tires on motorcycle rims. Just a thought..... Jim

You will probably want more gear than either a 901 or a flyer has.

Maybe a subie trans. Some of those much higher geared. But you have to research the numbers on them to find the ratios you need.

While many are doing this on their 2 wheelers, you might check with your insurance prtor to doing so.

Since you're building the trike here is an option for the front wheel: https://www.speedwaymotors.com/the-t...t-wheels/29346 .

You would have to select bearings and spacers to accommodate a straight axle and have front forks wide enough to fit the wheel. A pricey solution but you could an run automotive tire on front. Might be able to locate an "orphan" wheel on ebay or at swap meet to save money.
