For those of you who did not quite understand the concept of the "fin tubing" I was having made to further reduce the IC coolant temps, Here are some photos... This is 20mm OD / 15mm ID aluminum tube that has cooling fins brazed to the outside of the tube in a contiguous circle. This tube is used for heat dispersion on hydro pumps, pneumatics, etc. It has a heat dispersion rate of 12 X the normal dispersion of plain aluminum tube and 85 X the dispersion rate of nylon braided HP hose... This means that the coolant temperature would drop the same in 1' of fin tube as it would in 12' of normal aluminum tube, or 35' of braided hose.

It also has an insulation property that works in reverse...

This also relates to Lantana's question about the oil cooler... The OEM oil cooler that attaches to the side of the filter housing is built the same way, it's a small chamber that is sandwiched with external aluminum fins and circulates the oil from the engine up to the cooler then dumps it into the top of the filter housing which drains back down to the pan. This is the only cooling mechanism in the system... I have thought very seriously about installing an additional oil cooler / heat exchanger at the base of pan, but I won't know for sure if it's necessary until the engine is tested on the track with the new oil temperature gauge... If the temps rise above 230 degrees during race conditions, I will definately be adding one... It's good insurance...
