Mark,

about 20 degrees of rotation = (oscillating=20 CD), >130 mJ spark energy and up

Alain).

How does Klaus claim the higher values? Does the = LSE CD=20 system boost the
coil characteristics?

But to Marv's point, = the PVL=20 coil primary is .6 ohms and 1.65 mH. What
happens when the MSD = coil=20 doesn't match up to the LSE electronics? MSD coil
is
.35 ohms = and 4.2=20 mH. _http://www.msdignition.com/coil_blaster_9_8224.htm_=20

BTW, = LASAR=20 claimed about 40 degrees of rotation for spark duration and 60=20
