Voltage gains vs weight = run time?

Going to higher voltage will help you keep the current down. I had 8 minutes on an oval race, before I had to do a battery change. And this data was going full out, finger was pretty much on full throttle most of the time, except for the turns.
Setup was
1/8 Buggy Mayhem Pro
Motor: Feigao 12XL (1390 KV)
ESC: OEM-RC 12S100A ESC
Battery: 4S1P PolyQuest 25C 3700XP
Gearing: 22 Pinion, 46 Spur
Throttle EPA: Cut down to 75%
Cut-Off: 2.85V/Cell
Run Time: 8 Minutes
Temperatures: ESC was ice cold, Motor was warm and battery was cool. it was only a 10 Minute Main, but I could've ran the buggy all day without heating issues. And if it was 6S and a lower KV motor, the motor may have been a little bit cooler as well.

Even with the EPA cut down to 75% it was still the fastest buggy in the straight of the oval track. So if you were to move up to 6S 2450mAh 25C Lipo, and 925KV motor... You'd have a more efficient setup meaning lower current, more efficient and maybe a few more seconds of run time. The move to 6S is definately worth it now, especially when you can pick up a Monster Maxx for about $150... Or one of Lutachs ESCs for around the same price...

Why do you have your lvc set below 3v/cell?
