Hello all, this is my first post here so I'll briefly introduce myself before getting to my inquire for direction and recommendations. I am a 34 year old engineer who grew up on Yamaha Bravo 250s, Enticer 300s, and Enticer 340s. After all these years I have finally acquired my dream machine of a Yamaha Phazer (two of them actually). I keep them in Utah with my family and drive them when I visit. Of course they use them also, hence the reason for not owning something very expensive. Maybe someday ...
Anyway, I would like to design and build a small, one person, mini dune buggy (something like this
) powered with a snowmobile engine and CVT. I would expect that this will require a liquid cooled engine, 500cc or bigger, with an over sized (car) radiator. I would also expect that the most economical way to acquire all of the part I will need would be from a running, and perhaps wrecked, snowmobile. Something that is very common would increase the likelihood of finding cheap initial and replacement parts from old, wrecked and broken machines from sources like eBay, classified ads, and craigslist. I searched the internet for some comprehensive information about what engines are used in various machines along with some basic information about each engine such as displacement, number of cylinders, horse power, weight, method of cooling, ect. but I have not come up with anything useful.
So I am asking for your help in finding this kind of information and for your own personal recommendations. I remember when we began to retire our old machines that the Polaris Indy was getting a lot of attention for its innovative design features such as being liquid cooled so I looked there first but have not found anything very helpful. I look forward to any information that you can share to help me out. Thanks.
Also, EFI would be REALLY cool but I am guessing that will be prohibitively expensive.
