At work today I picked up some 5gram rollers to try out and here are the results.
The belt is a Bando 23100-KEB7-9000
Run1: 8.5g rollers rpm@7200-7500 during accel top speed 44mph
Run2: 5g rollers rpm@8200-9000 during accel top speed 38mph
Run3: 5 and 8.5g rpm@8000-8200 during accel top speed 42mph
Acceleration Times 0-40:
5 and 8.5g rollers: 14seconds
Just 8.5g rollers: 11.75seconds
What do you guy think about these numbers?
