The BD7'16 and BD8'17 came with the 34T diff pulleys. Ronald won the worlds and one ETS round on carpet. Yokomo changed back to the 40T pulleys at the ready race and the car was way more competitive and Ronald won the Euros.
That is what I meant that the 34 tooth pulley did not workout as expected on the BD8. This doesn't mean that it doesn't work on the MTC1.
BTW we are running the BD8 with the 34T pulleys and like it like it is.
