Oil Cooling
It was found essential to use two front mounted oil coolers from an MGB (Part No. ARO
9809). The coolers were mounted in tandem in the side of the radiator ducting. The air from the
coolers was ducted out underneath the car through an opening cut in the floor of the nose.
(Consult SCCA GCR pertaining to oil cooler ducting limitations.)
The oil lines to the coolers were routed through the chassis backbone for safety purposes.
A chassis mounted filter was used with the oil temperature being monitored at the filter head.
The standard oil pump was retained with a higher relief valve setting.
Driver Cooling
The left headlight aperture was used for driver cooling (essential in high ambients) and to
supply cooler air for engine breathing. A six inch duct was routed from the headlight opening
through the cockpit, with an outlet for driver air, and thence through the firewall to a cold air box
on the carburetors.
