Why? Hp of the motors varies regarding the voltage so yes it would not be the best performance for that motor but I’ll leave space for continuous improvements, also as stated previously I’ll be using the performance motor."Ludicrous" has a lot more to do with the battery, than the drive unit, afaik. I think that's just a performance LDU.
I doubt you'll be able to dump ludicrous amounts of current into the inverter of a PLDU with the pack you propose to use.
