[VintageLambo] Re: new radiator design?

Check out Ron Davis Radiators: http://www.rondavisradiators.com They have a big profile in the classic British sports car marketplace (in addition to their current NASCAR business) – these cars, as everyone knows, are about the absolute worst when it comes to adequate cooling (I am speaking as a long-term enthusiast!!). Their radiators are very high quality; some hesitate to paint them prior to installation [I have no connection to the company]. More generally, adding oil coolers to improve efficiency is an attractive solution. To do this without exposing them unnecessarily or without "chopping up" the bodywork can be difficult. I use integrated radiator / oil coolers within the car"s existing airflow. There is no damage to the bodywork and the next owner can substitute the stock radiator back if they don"t want to drive the car. In terms of efficiency, the "coolant : oil" temperature gradient is much less than an "air : oil" gradient. To obtain a similar heat exchange, a much bigger oil cooler surface area (within the radiator) must be used. What this factor should be is beyond my level of expertise.
