two speedos, one motor
 

Car racing...
I have a Mtronix speedo in my car, its pretty good but not quite as good as some, winning is getting harder now that two guys have new motors that are still BRCA illiegal and 3300 cells. Hard to compete when you've got 2000's and a normal stock motor and not the money to get new. money has now invaded our little track, skill is no longer enough :( even the really tight tracks dont slow these cars down enough for a level playing field
To the question...
i have two of these Mtronix speedos, what would happen if i used them together.. in theory half the resistance and as each speedo is working about half as hard as one on its own it should give me a bit more grunt.
Correct or no? is it worth it :D
