I've had this Exhaust Gas Temp gauge sitting around for a couple months and while I had the car up on ramps getting a new fuel filter (and it needed it!) I decided to pop this guy in place.
I got the parts from Aircraft Spruce, this guage, this clamp-on probe, and this 15' extension cable. All told, I spend around $100. This gauge has the benefit of being semi-original looking, ambient temperature compensated, and matches my Micro1000 CHT gauge. All I did to install it was drill a small hole in the exhaust tube, and insert the probe, tightened everything down, attached the cables and ran them to the cabin. I drove the car around the block, which was very interesting. My car has been running very poorly ever since returning from the RRC, and I thought it was just the fuel filter. But it's not. It was very interesting to watch the needle moving as I opened and closed the throttle and it also helped me visualize the problem that I'm having. My car has been intermittently losing power, and I would be driving along at a nice EGT, and the car would lurch, and I would look over and the EGT was extremely low. And since it is my understanding that EGT is more affected by timing than AFR, I can be pretty confident that for some reason my timing is wonky. This may be the KitCarlson EFI dying or a bad wiring harness connection. It might be time to *GASP* install a spare set of carbs and a Mallory. (IMG:style_emoticons/default/ohmy.gif) This was an affordable and easy upgrade. I expect that it will be a useful tool for tuning the motor and if anyone has an extra gauge slot to fill, I would recommend an EGT after you have a CHT. |

...westach...is available at aircraft spruce.....and is FAA rated. westach is installed in many O.E.M. aircraft, and they have many, many , variations of instrumentents, of all types and uses, including CHT, EGT. the EGT probes MUST be installed at a particular point in the exhaust system, or the combustion temperature reading will not be accurate. the location is furnished in the instructions.
