skymast, you have a point
But, tahoedawgz71 pretty much answered your question, we just discussed the safety issues with going fast so others that read your thread will understand the consequences of going that fast on a golf cart.
The bandit will run with stock everything. If you add a bigger controller get bigger wires. 4 gage is good, 2 gage is better.
As far as the Executioner, check the Plum Quick website, or maybe someone else will chime in.
I have a commander with stock controller/wires, it runs great. (28mph).
I'm getting a DCX500IQ, HP soleinoid and 2 gage wires.
My torque should more than double and my top speed should be about the same, maybe a tad faster.
Hope this helps
