Need motor gearing advise

It is only my suspicion that I got a 2Y. I can't confirm it, except to say that the motor is running fine, just slow, when geared for a 1900kv motor. I just dropped the 5S pack into the 8ight with the same 16/44 gearing and things really came to life. It's not as stupid as the 9XL was on 5S, but it's more of a sane insanity.

I have to get my truck back out onto the track and see how it performs with the higher gearing. At this point, I am now on the fence as to whether I'm going to return the motor to Neu for a check up. If it turns out to be fast enough for racing on the track with the gearing and 4S, I may just keep it. Those temps that I got were looking pretty good to me. I'm just wondering what my runtimes are going to be like. It would be something if I could run a 30 minute main on a single Kokam 4800 pack.
