Mike,

This must mean that mine is aftermarket too since headers lead to cats, straight down to sidepipes. Just like pictures of your car.

Just got mine back after significant weld job.

If you want a picture of the looping configuration there is a nice one from the black 95 for sale at Fastlane.

I think you are right. I know some of the welding on the four hole flange to the cat on my car is really "after market". Looks like some one in high school shop did it. But it hasn't failed! I may be wrong, but I think both type factory systems uded the Ford 5.0 exhaust headers as part of the system, whereas mine has a a kit car set of tube headers that terminate in the square four hole flange. I have no info on the source of these, but my quess is that they could be Classic Roadster since the two cars are so similar. Perhaps what we both have is CR systems with cats?

The yellow demonstrator Excalibur II shown at Carlisle two years ago is apparently for sale on ebay:

The photos show many of the details of this new version. Apparently the plans to produce them as a kit or roller or whatever are no longer being pursued as the listing says the body molds are for sale as well. A business opportunity?

Can anybody tell me what the right-most toggle labeled "Auxiliary" is suppose to do?

Do you have a manual switch for the radiator fan on your Excals?

Don't think the aux switch is wired to anything. Probably could use it for driving lights or ?

The computer controls the fan based on temp. I had to install a separate fan controller when I found mine had a '93 cobra computer swapped in (with some wiring changes also required). The earlier Ford computers (pre '94) did not control the fan as it was mechanical, not electric.

CobraDuke, what temps does Your car run & others if You know of? Jim brought his car to show me while I was getting some service work done on my dodge trk. & his temp was " Indicating" 220 & he did have some water spray under bottom side of hood & a full overflow tank. Mine will run 170 most of the time but in town & NOT under any kind of traffic I will see 200, mine has the mass flo computer & Jim has stock ? Wendell

I replaced the thermostat with a 180 degree (stock is 193) and it runs at 180 most of the time. I can't remember seeing over 200. I'm not sure when the computer is programmed to turn the fan on, but I have my fan controlled set at 170. Several have indicated the gauge indication higher than desired. One problem that has been found on some cars is the gauge accuracy with reports of 10 to 20 degrees too high compared to actual coolant temp. A couple have gone to an add on computer chip (can't remember the brand, but there are posts in this thread from a few years ago) which improved performance and reduced the overheating. I think part of the chip installation is the lower thermostat and possibly it turns on the fan at a lower temp as well.

If the fan is working, the timing set properly (10 to 12 degrees with the plug in the harness removed) and the gauge working accurately, probably won't see much over 200. I personally like it to run cooler than that.

If Jim is seeing high enough temps to force coolant out under normal driving, it needs some attention. Not normal.
