Delta/wye

For the last two months or so I have been researching on how to convert a hub motor to delta from wye, possibly with a relay setup; I was hoping to get some answers from you guys.
I know the steps, but I was warned that if I do something wrong it can cause the engine to stutter? I know the rewiring process and the way it should be done, and the basic precautions with soldering and whatnot.

I'll probably do a setup with bullet connectors (inspired by OutLawE-Rider) so I wont have to resolder or mess with relays incase I want to revert to wye.
Does the power consumption change? I'm planning to do it with a 48/52v 40amp peak controller.
Should I do it myself with basic-intermediate knowledge in ev's and some experience with soldering?
What other dangers should I know of?
Thank you!

It's my understanding that wye draws fewer amps, and that was the basis for several experiments many years ago. (*delta provides more RPMs for the same watts)

Since high-amp cells have become readily available these last three years or so, interest in delta/wye switching has faded.

Yes, but what I am doing it for is getting the maximum speed out of a motor.
I was told that someone was able to squeeze 60kmh/40mph from a 350w rated motor on a 20inch wheel, but the torque from 0-10kmh obviously became really poor, but I dont mind pedaling up to that speed and then activating the motor.
This is why I am interested in doing this (I also have a 350w ebike that I am planning to do this on, but still dont have the knowledge and confidence).

If you want to use a motor you already have, and you want the max RPMs from it without rewinding it to a different Kv, or changing the system voltage...then delta provides higher RPMs compared to wye.

40mph requires approx. 2000W so if that 350W motor did, it probably wouldn't be for long...

I do think it is possible with peaks of 18-20A on a fully charged 48v battery in delta.. or atleast 35mph.
For instance my 20inch 350w ebike gets to 24mph on level ground in wye. (15A peak controller 48v)
