View Full Version : How much is too much

How much hp. does a 12, versu, 20, versus 44 use at 8000 rpm. Is the difference between a MSD Mag 20 versus Msd 10 Plus, just the hp. used. Lets say we have a static 11.8 to one compression, 526 BAE hemi, with 70% overdrive and a max. limit of 8:71 Hi-Helix in a 4 engine modified pulling tractor. I like the MSD 10 Plus, but the team thinks the Mag 20 is the best. Running 2 deep cycle Marine batteries is not a problem. We are currently using Mag 12's, and have had zero problems with plugs, or dropped cylinders.

So as the subject said. How much ignition is adequate for the afore mentioned motors.
