One of the australian team ran one of these at the worlds last year and je loved it ! Power and reliability no problem, just the same old OS V Spec problem .. bearings ! and they dont last very long either .. 10 litres and youre out , plus the rods arent the best ... At the Jalkarta track which is about a 55 second lap he was getting about 8.30 to a tank

other than that they are great !
