Re: PI Plenum Chamber Differences

["Bernard Robbins, NEC New Zealand Ltd" <brobbins@wlg.nec.co.nz>]

HI Kai,

You are correct in that there were two lucas PI systems produced  the
earlier with single balance tubes and the later with double balance tubes. 

The plenum chambers for each are identical. I believe however, some of the
very very early systems as fitted to the TR5's and very first MK1 PI's
didn't have the embossed Triumph lettering on them. 

Sounds like you have an interesting project on the go....

Cheers
Bernard
