Default Quest for more speed tc4

Hi all, I'm just thinking about changing the spur/pinion in my tc4 for more top speed.
I have been reading through the forums trying to find out what is best but can't really find
A definite answer, everyone has different opinions.
I'm running a 5.5turn brushless mtroniks motor and esc with 2s 40-80c 4200 lipo.
I want to stay with 2s for now, my gearing is 29t pinion and 70t spur and I'm hitting 45mph.
Is this a good speed for this set up? What gearing could I go to for more top speed? Motor doesn't
Even get warm at the moment. I don't race it just use it in car parks.

Also I have the option to turn my motor power down on the esc, so was wondering if I did
Turn it down by 50% would this enable me to run 3s lipo??

Lower your timing to 0,run it on 3 cells.gear it up,you need to have your motor under load.if you don't your motor might burn up just from having it spinning at crazy rpms.how many KV do you have on your motor?

I'm not sure on the exact kv for the motor, when I look on the website under it's specifications
It just says 7000-8000kv.
So at those kind of ratings it's 2s max, the esc is the G2pro by mtroniks, with the program card
There is an option to turn down the motor power, at the moment it's on 100% this allows max power
I was only thinking of 3s if by turning this setting to say 50% would it half the kv? Allowing a 3rd cell?

I have read of people getting speeds of 60mph with 2s lipo with the tc4, I'm nowhere near that does
Anyone no what spur and pinion would get me this on 2s?
