I have a question I have a 6v 11000 rpm motor if I connect it to a 12v battery how much will the rpms increase? I am going to replace the motor with a 12v motor but im just curious

No-load RPM is generally linear with voltage, so you should expect 21-22k RPM at 12V. It usually comes along with 2x the no-load current, which means 4x the power and heat (2x current * 2x voltage).
