Besides, given the huge difference in specific heat capacity between oil and water, and the fact that the volumes of both oil and coolant interacting in the cooler are so small, it's unlikely that there will be any huge change in coolant temperature. What I'm really concerned about is whether that system will even be adequate at all to cool the oil. 99.99% of the problems with limp mode are due to sustained and aggressive track driving. Will that small and cheap cooler really be enough to prevent that from happening? If it doesn't then people will be hitting limp mode again and it will be the same complaints over and over again, and the same magazine articles bashing the Z again and again. Sure, the Z might last until lap 4 or 5 before shutting down, instead of lap 2 or 3, but still it's more of the same.

mags won't be hitting limp mode in their testing, that's almost guaranteed.
when you are heating the coolant at both ends, you run into issues. trust me. i've run into this issue before. the tipping point on the last car I ran with this setup was about 270. |

And what do you mean by heating the coolant "at both ends"? Is the oil cooler supplied by coolant flowing from the radiator to the engine or the engine to the radiator? Why would it cause a problem anyway? Look at the size of the hose going into that cooler. It's much smaller than the radiator hose. That means only a very small volume of coolant is flowing into that oil cooler. It doesn't seem likely to significantly affect the cooling system that much.

Anyone who is doing serious tracking will want a better oil cooling system anyway. That would be like trying to do serious tracking on the stock brake pads.

also, pharmacist, remember we could now swap the radiator instead of adding an air cooled system and probably get more from the car...
at this point, no real purpose in borrowing trouble from the future. I'm sure someone will find out where the limits are, and we can cross that bridge when we get there. |
