I need an opinion on my setup

[crazyjr]

Actually i think i know what to do, But value you're opinions and follow them when given.

My associated rc10T4 has a 4600 mamba package with 23/87 gearing running 2s 8000 maxamps packs. I ran it for about 30 minutes today and remembered to grab the temp thing, to see how it was actually running. Over the 30 minutes the motor temp was about 160 to 170 and the esc was around 120. Am i running too high a gear? Over the half hour run it never got higher or fluctuated, power was awsome and never thermaled. Should i go two teeth smaller on pinion? or, Is it good the way it is?
