Electric 1/8 Rules Debate

inefficient number ONE for you, you are running a 1515 in a buggy. that's wasting power right there. most efficient motor for buggy is 1512. and when i say 15mins, i mean RACING YOUR TAIL OFF 15 minutes!!! A guy by the name of Ryan at our track is winning 2nd to 3rd place in the EXPERT class running 15mins. To get 2nd or 3rd in expert class, you GOTTA be running your tail off racing. Also, the tekno crew run their tails off in the expert class with good results (2nd to 4th places in the A-main).
If he is using a higher KV (2700 kv for instance) you would be right, but anything around 2000KV is real efficient

I beg to differ with you on that, Bigger motor , more torque, more torque, less amps required to do the job, less amps required, less MAH used in a given amount of time

The 1515 1y (110amp) and 1512 2d (120amp) run about the same in terms of efficiency. Yes, the 1515 1y does not have to work as hard, but it isn't that fuel efficient. You really don't start seeing any significant gains in run time until you go with the next 1515 down which is the 1515 2.5d which only pulls 80amps. I actually found that the 1515's can run a little hot in a buggy relative to the 1512 because there isn't enough load on the motor.

To your 1/10 statement, I have a rc10GT converted with a Lehner 1200basic XL/quark 80 amp esc and a 2500 25c 5s flightpower pack. Compared to my T4 with a MM4600 and 8000 maxamps pack, it runs cooler and just as fast while running longer. Both cars are geared to similar speeds (42-45 mph) the T4 gets consistent 25 minutes and the GT gets consistent 32 minutes, that's 3.2 times lower capacity and 2.5 times more voltage, going farther, more efficiently.

I would bet you the 1512 2.5d on 4s will get you 3 to 5 minutes of additional run time. If you are having problems running 15 minutes on a 4s 5000 that means you are burning 333mah/per minute. There is no way you are going to burn that much with a 1512 2.5d. If you drop down to 250mah/minute you should get right at 20 minutes on a 4s 5000 pack.
