Ok, I really want an MSD Ignition Box, but can't decide on what one to get. I
know I don't want the MSD 6AL, basically because I don't and can't really
benefit from it, nor do I want to play around with the timing adjustments/rev
controls.
Here are the approx. prices taken from Summit just to show the price
differences:
MSD-5.................$80
MSD-6A...............$130
MSD-6 Offroad......$210
I do have an MSD catalog which lists all the information pertaining to each
ignition box. All MSD ignitions use multiple discharge sparks below 3,000
RPM.
***The 6A and the 6-Offroad box both have the same indentical operating
specifications
***The 6-Offroad box is "completely potted with with an epoxy compound called
ResTech. This material encases the circuits creating a water and vibration
proof ignition. Weathertight connections are also installed." This is the
ONLY difference there is between the 6A and the 6-Offroad. Is the
vibration/water proof worth the additional $80? I have no problem paying
that if indeed it is worth it. I just get worried that if I buy the 6A, with
the puddles, mud holes, and other conditions I drive in with my Dak, that the
6A won't be operating long if it's not sealed.
***I want to compare now the 5 Econo box with the 6 series(since 6A &
6-Offroad have identical operating specs)
1.Price, $50-$130
2.Both have the same 'Spark Series Duration' of 20 degrees crankshaft rotation
3.The RPM range with the 5-Econo is 6,000 and with the 6A is 14,000; I hope I
never come close to 14,000 RPM! So, here the 5 wins.
4.Max energy output for the 5-Econo is 140 Mj Stored energy and the 6A has
105-115 Mj per spark. Not sure about this!?
5.Primary voltage output for the 5-Econo is 375 volts and the 6A has 460-480
volts.
6.Secondary output really does't matter since I have an Accel Super Coil
putting out 42,000 volts; 3,000 volts less than MSD's Blaster Coil
Sorry so long, but I like to research every mod I do to my Dak before I buy
it and put it on. Any input/opinions on which one to buy??????? THANKS!
