this is my situation here, I thought I would post here what I'm trying to do, before doing anything, to make sure I have the right information.
I have what looks like a generic scooter to me, no log or decals. the scooter stock was a 500w motor. unloaded it ran 30mph. underload, it maxed out at 27-28MPH. The battery I installed was 60V 35ah, stock battery was suppose to have been 60V 20ah, but it didn't come with a battery. I upgraded the motor to 1000w motor, but I didnt see any speed increase at all. torque seems to be slightly better. I want to install my 3000w controller, at the same time, I didnt want to ruin anything. the controller says its 3000w 80A. I don't plan to go full throttle, I just want to be able to reach 35-40mph to keep up with the flow of traffic to keep drivers from reacting stupidly

e-scooter
60V 30A controller
500w stock motor
stock battery 60V 20ah

upgrades
1000w motor
60V 35Aah battery

Any advice would be helpful
 
You'll likely need higher voltage to achieve a higher speed, or a motor wound for higher speed (kv).
Let me ask this, if I was to add my 3000w controller to my fat tire scooter, would that be a better fit since my fat tire scooter has a 2k watt motor?

You need to provide more specifics on the motor(s). Is it direct drive? Heat is the enemy, otherwise you can put much more power through a motor than the rating (I run 7kW through a 1500W motor, just not continuously). If you have a temp sensor to monitor the heat, then you can run it safely if you pay attention and throttle down when the heat gets too high.

yes, it is a direct drive motor. concerning heat, I dont have a way to monitor the heat, outside of checking the temperature by what it feels like

Adding Statorade to the motor will provide some insurance/cooling. Not as good as monitoring, but will provide some leeway if you get too aggressive with the throttle.
It takes less than 2500w to maintain 40mph, provided the motor winding can achieve that speed in the first place, based on your input voltage (if your unloaded speed is 30mph, you can't go any faster at that voltage even with infinite power, unless your controller can apply field weakening).
