Topic: multi spark ignition?

[bumati]

Has anyone ever used an after market MSD ignition?    Multiple sparks below 2000 rpm is a good thing,   right?

i run an msd and coil, and yes it delivers multiple sparks under 3k rpm's which is a good thing, over 3k it delivers one large spark.

well with renix system is a small pain to mod .i dont do it the way msd says to do it -i replaced the dumb distributor with a earlier one from 1986 one with carb -find some wiring pigtails to mod in -coil is a ford msd tbs coil and mount from a L-6 upside down mounted from the relay mount - msd is mounted off firewall rail with a wire guide from saab 9000 ..........and she runs far better !

On a side note, pretty much all the Multi-sparc variants can only multi-sparc to 3000 rpm.

I have run MSD on many vehicles and they always helped idle. On the dyno
none of them yield any HP, but you can tune things tighter to the edge and
run a little more gap.
