Oil cooler question

Why the hell there isn't a large core air radiator for the oil cooler exposed to airflow from the front of the car is beyond me. Having the oil 'cooled' by the engine coolant alone makes no sense to me. It's great for getting oil temps up quickly, so perfect for emissions and gas mileage testing; not so good for keeping oil temps down when the car is under stress.

IF the engine cooling radiator has enough capacity these oil to engine coolant exchangers work quite well. It should be plumbed so that it is in the return flow from the radiator so at that point there is a large temperature differential between the oil and coolant. This type of cooler does bring the oil up to temperature more rapidly and avoids having exposed oil lines and cooler subject to damage. The more effective heat transfer avoids the issue of pressure drop through a lengthy and restrictive cooling circuit. Oil to liquid coolant exchangers can be extremely effective but everything depends upon the engine cooling system having sufficient capacity and this is where a problem may lie in the Z06.

I wouldn't add anything in front of the radiator. I would like to upgrade the radiator, but there is absolutely no room.

Exactly what I did on my Nissan 370z and no more over heating issues (limp mod) at the track...

Unfortunately, people here are saying the Z06 has no room for a thicker radiator.
The aftermarket will come up with a clever solution. Fingers crossed.

I will take a water/oil cooler any day over the air to oil. They switched over for a reason.

Good discussion here. In case anyone isn't sure what we are talking about, here's a link that shows the production oil cooler: http://www.corvetteonline.com/tech-s...e-power-curve/
I don't see where there would be a lot of air flow around this cooler, and its close proximity to the exhaust header isn't helping the situation. Just my 2 cents.

Airflow isn't what cools it. It is a water block. The car pumps water from the radiator through it. Doesn't need any airflow.
