AKPILOT, wow, that was a butt load of finding answers. Amazing work. There are several things I am to fool with on this build that I've used successfully in the past. Since this is a single cylinder the build will be TBBT.. That translates into Throttle Body Before Turbo. This aids in two areas: One the use of a blow off valve is eliminated and two turbo lag(iff all other areas area addressed) can be brought into a completely tolerable range. The use of a TB pre turbo is debated in the snowmobile world, some love it some do not. On a single like the 350, I Feel that this is the route to go. The philosophy is that the turbo is basically kept under a steady direct vacuum when the
Engine is running and the throttle blade closed, thus keeping energy transferred to the turbine which ay more readily spin when the throttle is opened. Also, I'm looking at a turbo with ceramic bearings. The ease with which these spool is amazing.
I had watched the video of your 700 turbo pilot many times, just didn't realize it was yours I do love the front wheel dangle..I also remember reading the post where you discussed the arctic cat pipe you purchased. I have kind of a curse, I remember EVERYTHING uhg, just ask the wife..
I am currently working with the engineers at ecotrons to see if we can truly configure their efi system to work on the build..
