Mini Cooling

[Boyscout]

In light of my post above, I decided to have my radiator re-cored. This gave me the opportunity to have the core of my choice fitted. The cheap radiator as mentioned, has what is called "flat fins" and only about 9 fins per inch. It also has three small cores which are offset and cause a lot of turbulence inside the radiator, totally inadequate for anything larger than a 998. So I opted for a three core, inline with the more modern v-fin arrangement.
   
   

This is now a similar configuration as this http://www.minispares.com/product/classic/ARP1106.aspx 

I have fitted an 88deg thermostat as well as it tends to overcool with the 76deg thermostat. Gets up to temp in good time and at least for now it seems rock steady at just over 90 deg. When switched off the temp gauge (mechanical) rises to about 98deg but drops quickly back to 90 when started again. Still have to see how the performance is in summer and traffic. No electrical fan for now, only new plastic one. I could still go back to the 76deg or even the 82deg thermostat if needed. but I want the temp to be in the low 90's but consistent.

Previously with my auxiliary cooler it would rise up to just under 100deg in traffic with electric fan running full time, then come down to about 85 on the open road. In my opinion this is too much of a spread. At least for now it seems very consistent at just over 90deg.

I also plumbed the heater return from the head through the intake manifold plenum and then into the top of the thermostat cover. 

So far , so good. Will post some more pics and update of the performance later.
