Here are some photographs of the fibreglass modification to the rear clam bodywork to accommodate the exhaust system.
I now have a good 50mm plus of clearance between the exhaust headers and the bodywork. The increase in airflow in the engine bay can only help maintain an acceptable engine bay temperature.
I glassed the recess from inside the boot is case you are wondering how it was stuck in place!
After a good few miles driving I checked the bodywork temperature and 52C was the highest I measured so I am happy with that.
My current problem is a coolant hose collapse! When ticking over and running slowly, less than 3,000rpm, the coolant hoses maintain their form and coolant temperature is ok. When I hit 4,000rpm the temperature gauge starts to climb and as soon as I slow the revs the temperature falls back in a couple of seconds to 80C! I believe the water pump is sucking a hose flat. When I stop and jump out with my infrared temperature gauge all the coolant pipes are at around 50C with the exception of the top rail!
The car will tick-over all day at a maximum of 85C!
