I don't know if I this will help any, but I personaly have not
had much luck with MSD. When I purchased my MSD ignition box
it did not work (brank new out of the box), and since my car sits
for long periods of time the MSD box stopped working a second
time although MSD did repair it undr warranty, but shipping it to
Texas (and having to pay the shipping) stinks. Not long ago I
built a blower engine for a clients cobra we used a MSD BTM system to control detination. With 12psi of boost I set base timing
at 12deg. and set timing retard at 4deg.. This created 475bhp
at the rear tires (it is a scary car to drive!). Later a Saleen custom
ecu was installed which made the BTM obsolete it controled ing.
timing retard internally base timing still set at 12deg.
I am curious myself of the Jacobs system, but not willing
to spend the money to experiment.
