Done with the Ammo in this App. I have a small boat I might try it in with water cooling??
I'll try some steeper gears with the Medusa also, looking at the graphs I see very few points over 75 amps. I also want to try increasing the timing slightly with the Medusa, I found in the literature that came with my motor an 8-15 degree timing reccomendation.
I kind of like the punch the Ammo has, the Medusa seems to be smoother, easier to control the power. The punchyness keeps you on your toes becuase you never know for sure if it's gonna slip out from under itself, so somewhere in between the two would probably be my ideal.
I just spent the last few hours putting the Medusa back in and doing some quick runs in the yard just to see what kind of peaks I could pull on taller gear ratios. Started with a 15/68, pulled about 80amps. Went to a 15/62 and pulled 91a. I figured what the hey and tried 19/68 and pulled 106a and it still dosent have that kick the Ammo does.
I honestly dont need any more than I was getting with the 14/65 gears so I put it back to 15/68 and I want to run straight through a full pack, right down to the LVC to chrck for temp issues. If I can make it through a full pack with out temp issues I'll start tweaking the timing. Cold, windy, and snowing this morning:(

Water cooling will make a huge differenc in temps. I tried a sv27 6 pole motor in a few different vehicles, and it ran too hot with just air cooling. With water cooling, pushing the sv27 at 42mph it does not even get warm. Something about having a billion gallon radiator seems to drop temps!?
