Problem is Jim over the years I have re-built and uprated many overdrives
and changed the ratios, only last week I changed a BN1 from 28% to 32%,
although I would assume that this would be only a very small percentage that
have had this carried out.
I also modify Laycock model "A" overdrives to eliminate the "dwell" time
that it takes for the unit to activate, this means that the dash switch is
like a modern paddle change, it is absolutely instant, the same when you
disengage also, that way in competition at no time do you have a
transmission with a box full of neutrals, the drive is always constant.
Numerous other modifications are carried out to overdrives but I think that
this will put another angle to this question.
Kind regards.
David.
