16v or 12v and alt.

I for one do not use a 16v system unless you have a ton of electronics. Full digital stuff. If you are running the normal MSD 6al or 7 then go to DMI and pick up one of there Alt brackets. I only use their brackets as there is never a thought of it fitting. Here is the the link to DMI http://www.dotymi.com/Alternator_brackets.html

A simple 60 amp one wire alt off of EBAY for $80 and you are golden.

I for one do not like to have to haul a battery charger to the track and most tracks now charge for the outlet.. If you do not use theirs you have to have a generator.
