It would be great to know.

Interestingly the 09 Factory runs very hot compared to the 2013 R. I haven't yet worked out why, as the R feels slightly more powerful (bugger all in it though, now I've got the Race map ECU in the 09). The R will sit at 86 all day, even in 40 degree heat, whereas the 09 is at 98-100. Odd. The radiator in the R is the massively bent and straightened one, so cooling would be way less. The 09 rad is in mint condition.
