Hi All,

I've spent over a year designing a cabin adjustable, switchable high/low, mechanical boost control system for Scoobies (well it would work with any turbo car in fact), and have final designs ready now.

The detail is posted on Scoobynet, but I feel it's been somewhat misunderstood there, or that literally no one else is interested, I'm not really sure! Hopefully you guys may appreciate it more.

With a small tweek it could also be made into an all-in-one unit for MBC+EBC since uses a pierburg 3 port for the high/low switching anyway.

If anyone is interested, drop me a PM

bazil,

it looks good. is the design such that an electric servomotor does the actual adjustment of the underbonnet MBC?

It's a normal motor rather than servo. Boost is controlled by the dawes mbc in the usual way, but you can adjust the dawes from inside the cabin, instead of needing to get out and lift the bonnet.

The switchable versions then let you choose between mbc or wastegate, or between 2 mbcs set at high and low boost settings.
