The Papadakis iM has quality wiring with Raychem wire and mil-spec connectors. We always stress that wiring and plumbing failures cause most of the problems on race cars and you should never skimp on these areas.
The Motec PDM that handles the electrical components in the rear of the car. The PDM is mounted to the housing of the dry sump tank in the back of the car.
The rear bay of the iM has the radiator, fuel cell, battery and all of the associated pumps for the fuel system and cooling system.
The rear bay is dominated by an ATL Florocell 600 fuel cell with an exotic fuel safe bladder. Like most FD cars, the unibody is cut away at the rearmost suspension pick up point as per the rules and replaced with a tubular structure. This makes the car more repairable in an accident and reduces the weight. There is some nice fabrication back there!
The C&R motorsports radiator is mounted in the rear to improve weight distribution and to put the radiator out of harm's way.
The high mounted surge tank has several bleeds from around the cooling system mounted to it with an active suction drawing coolant through the surge tank from the bottom. This continually purges air from the cooling system.
