Greetings from Iceland
 

Hi there.. specialists!

I'm rather old, 52 but full of life! I own 3 cars, one motorcycle (Yamaha R1) and two snowmobiles (two strokes) I'm a very advanced programmer and programming for Arduino as a hobby these days.

Next winter I'm thinking of new project, turning my 1000cc 3cyl two stroke into efi and then if everything works fine, into forced induction, with exhaust turbo charge.

I have been studying turbo charging two stroke for couple of years and my conclusion is it is not as difficult as it was believed in early years of snowmobiles and two strokes (before 2000).

That's mainly because even though two stroke is open through (almost no valves), then back-pressure is build up because of exhaust restriction of turbo it self.. as you very well know.

So, I'm intending to plan it very well ahead. If you can advice me on this way, I would appreciated greatly. I have to choose turbo precisely because of the design of two stroke. Back pressure has to be proportional with intake pressure and controlled with both intake and exhaust valves. (micro-controlled waste gate valves and bypass valves)

Anyhow, I will post further in the future.. thanks ahead!
