Revised Coolant System

Based on the oil cooling performance I have been achieving I decided to complete a few upgrades. I have decided to fit a larger Laminova oil cooler, a 80 litres per minute water pump, to move the Laminova to after the engine and to re pipe the system in 32mm hose.

I have moved the pump to the front of the car, re routed the hoses and moved tha Laminova position from being after the radiator outlet and before the engine to after the engine in the return to the radiator. I have removed the restrictor as I will be running the coolant system at a higher flow rate.

I managed to get a replacement connector made to the cylinder head with a straight outlet and 32mm bore. As it was made of aluminium I tiger sealed a piece of paper gasket to the back before fitting in place. 

The setup is as recommended by SBD with the Laminova after the thermostat connector. I also took the opportunity to shorten some of the oil hoses to the cooler and re route them away from the exhaust area.

    Eddie,
    Your cooling setup is very nice. My plan is to go for the same setup. I have an EWP80 and a C43-335 laminova. I have made all the plumbing but I'm wondering if a plug or restrictor is required. What are the oil/water temperature you reach ?
    Thanks for your reply.

      Hi Jeremy,
      Thanks for the interest in my setup.
      With mine, I ran a smaller cooler initially and then upgraded to the higher volume water pump and Laminova. In the end I chose not to run a restrictor based on having a higher volume water pump.

      The cooling has been a lot better and oil temps don't go above 100 degrees now and water at no more than 85 - 90 degrees. This is with the additional heat load from the turbo in both water and oil.

      I would run it without the regulator and then if you have problems run it with.

      Good luck

    Hi Eddy

    Thanks for your feedback. I will first make a test without restrictor in order to see what I get. I hope the controller will manage not to overcool the water on road use and to keep good temps in harsh track conditions. My mean concern today is to have 65°c in water while cruising on road.

      Hi Jeremy

      Do you have a speed controller for your pump? If this is the case then you could run the pump at a lower speed at lower temps and then speed it up when it gets hot.

      Mine runs at 20% speed until 60 Degrees then runs at 100% above.

      Regards
