Well I just told you such calculations ain’t worth much when comparing different manufacturers. You only fool yourself with those numbers and what’s the point of that? Following your analogy a Tekin T8 motor would draw 220a then. That is 6,55hp for each making a total output of 13hp. Way more than a Castle 2028 system – Go Tekin

At best, what you just found is the performance of the Castle 1717 1580kv motor. According to Castle that motor is just about all the Mamba Monster esc can handle and therefore might be close to a 120a rating (Castle standards that is). The 2200kv motors in your setup is quite a lot weaker though. Don’t get me wrong here, your setup is impressive – but getting the numbers right is something else. Happily that is just calculations, what you are looking for is true performance. Generally larger motors draw more amps, and therefore a higher power output. Luckily there are a lot of options stepping up from the 40x75-size you currently use, as long as you are able to make the proper gearing. Twin 40x92 motors might be an excellent choice

As for drivetrain loss, voltage drop and so on is not of much relevance as long as the car stays the same along with the batteries (given they are dimensioned for the power system in question). That is the beauty of relative values

Can't wait to see your Savage rocket reaching 120mph!! Awesome built Skillet!
