you mean to vent the air to atmopshere? or vent the SC air to before the SC? venting all the air the SC pumps is wasting the power that it took to actually create it, ie whatever the SC's crank loss is. venting to before the SC is similar to my idea anyway?

Yes, vent the air to atmo, or back into the sc/turbo inlet.
You only do this during the sc->turbo stage to smooth the transition out, not as a way of turning off the sc (use the clutch for that).
But the exact setup would depend on how the sc & turbo were configured adn what order/system you wanted them to run in.

if some of you boffins out there can design a stepper motor controller system to control, that can reference TPS and a couple of pressure measurements (using motorola MAP sensors?).. then we could be in business Wink

(not literally Razz

)
how much force can steppers motors exert (against air pressure and return spring pressure)? how fast can they move? and how accurate could they be for a sub-90deg movement?

This would be the interesting part for me (i am a elec engineer).
Though i enjoy doing the mechanical stuff just as much.

Working out the control mechanics stuff (like the servos) would be quite difficult, but it can be done.

how easy would it be to have the characteristics programmable??

Depends on how much time you want to spend on the software.
Getting it to work is one thing... making it easily usable is another.

i do have a motorola MC68HC09 (sp?) programmer Wink

they are pretty cheap and easy to reprogram from scratch (if you have a compiler Sad

) the MS code has been written in both assembler and C already...

I would probably do the whole thing off a laptop to begin with.
Easier to program and test with.
When working, itll be easier to work out whats required to move it onto a dedicated ECU.

hmmmmmmmmmm..... but this takes away from the DIY junkyard approach... but then again... it could start a whole new MS-like community of crazy bastards wanting to run stupidly big turbos on tiny poor little engines Evil or Very Mad

It still can be done backyard DIY style.
I designed & built an ECU similar to the MS based on a AVR here at home... i just never got around to writing the software for it.
It just takes time, knowledge and a few $$s.

I wont be attempting anything like this myself for a long time though.
The 1UZ into RA28 will keep me busy for a long time yet.
