runs cooler w/out the restriction of the shroud/fan assembly.
don't see any conceivable way you would hear a cooling fan running on an unmuffled race car.
Anyhow, when you run at Lime Rock, you can't do that. That and you get tired of being DEEF! Speaking of something else with no real point...

I say keep the fans. Mine are wired with a switch, and the only problem I have had with that, is forgetting to turn it off when I go back on the track. I have thought of putting a huge red light in so I know when they are on.
One other thing, I now have a 944 Turbo radiator on my 1983 944 race car, and it works better than I had imagined. Nort Northam had an expensive aftermarke radiator, and changed to a 944 Turbo, and it was better. I am not sure you Class I PCA types can use a turbo radiator, but we in SCCA can.
I still use the fans to cool the car down fast.

John, irrespective of having a physical muffler, its pretty easy to call a ~100dB car "unmuffled" irrespective of it technically having a "muffler." In my case, I began running two Dynomax in-line and didn't show up on sound. Nonetheless, I severely doubt you can hear a fan switch on - but I wouldn't know because I haven't had a radiator fan in the car for 3 years. Have fun with that cooth one, sound limits are 103dB for SCCA and I am just shooting to be below sound (and currently am not even showing up on sound w/ the second "muffler").

How about wire 'em up, put 'em in place, and then only use them if (actually when) you need them. Look at any of the race car projects that have been posted around here, all of them have fans. Control of oil temp helps, but it won't keep you from toasting your HG like water will.

I run them manually from a switch (actually, the A/C switch with the A/C relay removed) and have the thermo-switch still in place. I need them when I'm ******* a car, especially a 911 with all the heat coming from the back of those cars, and on the cool down/transit to the paddock.
