Single ram mid is horribly slow with an oildyne pump, and not near fast enough for drag racing. The goal is to have a fast enough trim that the hull doesnt slap the water on takeoff. It launches out of the water and the trim is fast enough to keep the hull in the air.
Wiring the oildyne (one that looks like 2 coffee cans end to end) up with 24V on the up side makes it a bunch faster.
A mercruiser pump (the one with the plastic reservoir on the bottom) is a lot faster than the 12V oildyne and almost as fast as a 24V oildyne. I really didnt notice a difference when I went from 24V oildyne to 12V mercruiser. A mercruiser pump wired with 24V on the up would be blistering fast, and probably unsafe for someone not using a trim computer (my opinion).
If you are rigged with a mercruiser pump, you should be good to go, but if you have an oildyne you may want to try the 24V solution to improve your holeshot times.
