Yeah Mario has 600HP at the 4 wheels at the moment. He has spent alot of money on the Cams etc.. he would never tell you the exact setting for them..
I think his is also drivable with 600Hp at the 4 wheels.. but that costs the extra money.. I know people with 500HP, but they don't last long and are not drivable.
So good to see we get each others points. A twin setup will never be the good option for over 600hp.. but what fun it would be
