Default I have a hpi sprint 2

I have a hpi sprint 2 it came brushed with a 15t motor I put in a 3300kv motor and esc and I was hoping someone could tell if I put in a 4250kv motor and put in a 28t pinion and 81t spur gear would it make the car faster my brushless seems slower than my 15t but if I put the titan 12t on how much quicker would it be between the three motors brushless 3300kv 15t or 12t I need recommendations please someone let me know thanks

If you're using a 2S lipo battery the 4250Kv will run faster than the 3300Kv. A 3S lipo battery with the 3300Kv motor would be even faster.

You can barely fit a 2s in the Sprint 2 let alone a 3s.

You could always drop down to a smaller spur gear also....
