So who is going to go flogging their cobra around a race track in Australia before the
oil has got up to temp?? Unless of course you are in goulburn.... The other thing would be to get rid of the thermostat. For most Australian Cobras the cooler is for 'the look'. Unless you are going to race it then it is not necessary. I raced mine for years without a cooler. 8 laps at Queensland Raceway sent the temps a little too high for my liking so I installed an
oil cooler. Have been racing mine (now retired from racing it) for years and no issues with cold slugs of
oil. If you are that concerned then I would get a heat exchanger instead of an oil cooler. A lot more efficient at getting the oil up to temp quicker and keeping it within 5 degrees of water temp. V8 Supercars only use heat exchangers if anything.
