It's a 350cc engine with Roots compressor.
It is a prototype to arrange a more powerful small engine in order to face italian laws of 80's about drivers licences

Well, whats possible with 350cc might be possible with 1000cc, too...

350,750 or 1000cc with a 4 rotor roots compressor and some nitromethane ya can blow the heads right off

this one looks even more professional:



maybe I should have started a whole new thread "supercharged Ducati twins"?

is that a Weber on top ?

G it´s a dell´orto

Just googled it today by accident. The machine is modified by this small(?) finnish company http://jlmeccanica.blogspot.com/

they´re building a thing called 996 Compressore, I´m definately going to stay tuned. Quite an interesting project indeed. Most of the info is in Finnish, but there´s sometimes a small english summary.

Weber don't do carbs anymore they are all subcontracted anymore

As a matter of fact, one of the best problem with such a job is tuning the engine... ignition, timing, carburation, inlet and outlet mainfold diameters, compressor pressure and so on. Moreover the larger amount of air and fuel in the engine will cause a critical raise of temperatures of pistons, heads and valves

Yes thermal management is the key to any mod

Yeah heat control is an issue but less so with a supercharger than with a turbo. The fact that a motor is air cooled will add to the problems because increased airflow is not an option. (Though I do see the engine here is water jacketed) Direct water injection might be one way forward.

Me? I'd just stroke it and bore it and to hell with the physics . . .

I guess this belongs to someone who was rolling on his last set of precious Michelins Why else would one need this feature ? Or maybe there`s a lube dispenser on the other side

Look at the carbon fibre parts. is it real carbon fibre?

Where do you see carbon ??? The black parts are painted black.
