pinions

[4_cell_racer]

I tried a 27t pinion with my 10.5 running a Tekin speedo (boost etc turned up) and found the motor was getting quiet warm!

Changed to a the kit 21t and it felt slow (at Ardent yesterday) so bought a 22 & 23t pinions and the car felt more on pace....just the driver letting the car down lol, going to get some more pinions so I can test it some more on different pinions
