e-revo and speed car combo

[tt-01 mamba]

Hi.
I am going to try and continue Dagger Thrashers lite speed car project.
Would a neu 1515 be too powerful or underpowered in an e-revo running on 6s mostly bashing t WOT?
I will be getting a MMM to run this after all the kinks have been worked out

i want to get a 1515/1Y 2200Kv so i would have about 48k rpm. i am not trying to make the fastest rc car out there but something respectable.
Should i try to get higher rpm?
I am only going to buy one set of batteries for my e-revo and car.
