Sorry, I've been quiet, doesn't mean nothing is happening, just been busy working and refining a few projects.
This TPI thing is getting interesting, just lately KTM have decided to provisionally patent the TPI system. They cant because all my original development has been well documented here on TSM and the videos I released back in 2013.
An other manufacturer is pissed as they are about to release their own B port TPI. There will be a fight.
Thank you Ray for resurrecting this forum and saving all my old injection stuff, who would have thought?
As for my Mk2 TPI (the 360) its become a haven for spiders. But the need is on now to get it running and get some results, I would like to think by the end of the year finally! I'll post some update pictures in the EFI 360 thread soon.
As to this piston design, yes I have seen it. Wasn't so sure but after some thought I like the idea, might even make some myself. I was worried about weight but that now seems unfounded. I didn't notice, what grade aluminium did he say he used? I guess the good thing is they can be machined from bar stock rather than cast.
