What is very interesting on newer cars is just how small the radiators are and how well the fan systems work with them. Nearly all of radiator is covered by the shroud and there is a very high open area ratio. If air cannot freely flow, cooling effectiveness is reduced. This is very important when space is at a premium, even for our applications where turbos/intercoolers/plumbing take up a lot of space.

As said earlier, mine is too big, and the car has a problem getting enough heat in the oil during the cooler months. I'm fabricating a block-off plate that will slip down the front of the radiator and block off a portion of the top section during the winter months. A thermostat would be a better option, and I'm in the planning stages for that as well.

A technical story would be very interesting. Each type will have advantages and disadvantages. I have a lot more respect for a product when the company points out not only where their products work, but also applications where it is not well suited.

Hey Carl,

C&R felt that a shroud should be ran on the street and shouldn't be ran on the track. This is due to the high track speeds over pressurizing the fan. With the lower speeds on the street the shroud is a good idea.

Also, I talked with AFCO and they are going to make a radiator with the built in oil cooler similar to the C&R piece. In fact they are working on it right now.

I also heard BeCool will do it on request.

Sort of nice to have more options.
