I've just fitted a set of 285 MTZ's to my GQ Coilcab whilst the motor was getting a complete re-build. My question is that how much power do the 285's drain compared to the original 15's. I have driven the vehicle in nearly three months so it hard for me to gauge the loss of power and also with a motor thats still very tight and yet to loosen up.

Probably around 8-10 Kw's at the tyres.

The kW should remain the same.....torque reduced in each gear about the same % as the rolling circumferance increase in the tyre...I think this is the math...

Cheers Andrew
