Hi folks,
Posted this in the MMP thread but it's pretty empty in there. Since this about putting lots of power in a B4.1, I thought I'd check with the experts!
Hope I can get some initial setup advice here. I'm about to install a MMP and 4600kV 1406 Castle motor in my B4.1. I was going to start with a 19/87 pinion/spur. Running on a outdoor hard pack clay track that gets a bit black groove when moist, but dries out often too, making it kind of loose. The locals here in AZ pretty much run Double Dees on the back. It's about a 30 second track, great times in the 25s, with a lot of jumps and turns, and really only 1 straight that's not long enough for full throttle for more than a second or so.
I know it's a lot of motor, but a wanted something to give good punch and torque for digging out of the corners and, well, be a lot of fun! So please don't just rain on my parade, I know I'm going to have to turn it down.
What I'm looking for are some tips for setting the throttle and brake curves, torque, punch settings - whatever else might be a smart way to properly harness the power of this setup... thanks in advance!
Any more info needed, just let me know..
I just recently put on a 6000kv HW motor on my B4.1 and running it at 25/72 and the thing absolutely rips, tons of acceleration and top end, too much even. I turned down to EPA to 75, I don't have torque or power settings but I set punch down to 3 from factory 7 which helped coming out of the corners. Also I would run a little drag brake because it is gonna be blazing fast it'll help you harness the power better IMO. Good luck, I honestly think that these buggies do best with the higher KV motors, as long as the driver can handle it of course.
