Hi,
How do I tell how many turns are these brushless system compared to brush motors?

Examples:
Novak GTB 3.5
Novak GTB 4.5
Novak GTB 5.5
Novak GTB 6.7
Novak GTB 7.5


I wanted something similar to 23T motor.
Does all brushless runs in sintered rotor?

I am also puzzled with mamba max numbers 4600, 5700, 6900, 7700. What does these refers to?

I don't now a lot about Mambas. This link may help.?
It tells the equivalent turns per brushless vs. brushed.

Just have to click each motor link.

With the Novak, a 13.5 sintered will get you close to a 23t and maybe closer with the new 13mm rotor Novak has come out with.
The motors you have listed a re mild mods to hot mods.
The 23t is an outlaw stock.

Well, there is no DIRECT turn comparison from brushed to brushless, but as far as performance goes, Novak's 13.5 Pro is VERY close in the way it runs to a 23 turn brushed motor(& FYI, all of Novak's Pro version motors have sintered rotors in them, & that's definitely the way to go, they run MUCH better with sintered rotors than the original bonded ones). And about the Mamba numbers, I'm not 100% sure, but I think those are kV numbers, , mean something like how many rpms they'll pull per volt applied to them(so if correct, a 4600 would rev to 33,120 rpm on a 7.2 volt 6-cell pack)....

The mamba max motors numbers refers to the KV, or how many rpm the motor will crank out per volt
