made to direct coolent flow in the proper directions after it is conne= cted to the center housing.........This system would seem

 &nbs= p;     I am interested in your opinion as to if th= e benefit would be worth the trouble to implement such a cooling system ?..= ...

I have heard that the rear rotor ten= ds to fail more often than the front perhaps because it runs hotter........= ..Has anyone to

your knowledge ever docu= mented how much hotter the rear rotor runs as opposed to the front rotor ?.= ............

From here can see= n the aluminum adapter plate between the two engines, which features the li= fting eye that you see sticking out of the top/center of the engine. The ex= ternal cooling plumbing can also be seen entering and leaving the center ho= usings, as can the dual oil filter setup, which serves as a distribution ma= nifold for supplying oil to the rear engine. The huge airbox filters out th= e dirt clods using a reinforced furnace filter (hey, I was on a budget). A = Chevy power steering pump assists a Ford power rack & pinion steering g= ear. Unseen behind the firewall is a custom made planetary "quick steer" bo= x, which speeds things up quite a bit, resulting in 1 turn lock to lock ste= ering. No need to take your hands off the wheel, no matter how out of shape= you get!
