    Thanks for the replies. The OE air-oil cooler has already been upgraded with a larger CSF unit. Water temps stay in the 85-90C range on track, so pretty normal. My question is specifically about why I get a rather sharp drop-off in pressure above 130C (progressive or exponential drop, as in my...

    sharp oil pressure drop-off > 130C
