Given the interest in getting rid of SAG - its important that we are all on=20=
the same wavelength when discussing components.=C2=A0 For example, there are=
 a whole bunch of different MSD ignition systems out there - I'm not certain=
 that they are all Capacitive Discharge types.=C2=A0 It may made a differenc=
e regarding their ability to avoid/delay on set of SAG.=C2=A0=20

=C2=A0

At least Lynn's assessment about the rise time of the CD type driven coils b=
eing so fast as not to permit much voltage =C2=A0leakage via the lead deposi=
ts and thereby avoiding SAG seemed to make sense to me.=C2=A0=20

=C2=A0

So the question to Bob Mears is do you recall whether the MSD system being u=
sed was a Capacitive Discharge type?=C2=A0 Thanks!

SAG can appear any where apparently. We ran a MSD system on our race care an=
d still ran into the problem. The problem ended when we switched to alcohol,=
 but thats not a fix for airplanes!
