ok, here are the specs of the car, im going into big detail so you can see the power drain...:
MicroSizers Pro 49MHz booster chassie
stock wheels+gears
Perfection 4.2 King motor
Perfection (LXX) 120mAh battery
Super Perfection blue tires (hard)
LXX Nissan Skyline: Calsonic
clone auto centering spring
XMODS gear grease on axel
the final non-stop runtime without boost was about 4minutes 45 seconds.......can be rounded to 5 minutes
hope that helped! sorry about the delay!
