Hi yes JDM - 2wd - 'rolling road' is a dyno test that can measure the Brake Horse Power at the rear or front wheels - is just 2wd tomorrow but they are have a set of 4wd rollers sorted in the near future so it will be fun to see what power is actually at the fronts in TOD - could be interesting as minor tweeks can be measured in output power - things like a conical filer etc
cheers
