I had a few 911 guys asking for a gauge to replace their redundant clock, the most asked for unit was a voltmeter/CHT gauge. I built this one as a test to "gauge" interest. Whaddoya think? Here are some other 91 gauges I did this week as well

Sweet! Volts / CHT is more useful than my clock that keeps running slow. Any idea on price yet?

Yes!

So...how much?

Like most things it depends on price and performance. The volt / CHT gauge looks nice. Can the volt meter just read any 12 volt source or will it need a special feed from the charging system. Will the CHT gauge read the CHT from the fuel injection sensor without affecting the values the fuel injection? Where will the CHT gauge get the signal?

I would love to have a gauge like that but how will I hook it up and what will it cost?

My clock just went south. Would be interested in the volts/cht gauge. How much?

im in on this! how much?

Nice indeed!

+1 on "How much is it going to set us back?"

Had no idea what CHT stood for...so did a google for acronym finder and my guess is cylinder head temperature. So my question, why would we want to measure this?

The cylinder head temperature changes with mixture. It you you run too lean it goes up, if you run rich it will be lower. It's a very comon instrument in aircraft engins where you constantly have to control the mixture due to altitude-induced air density changes. On p-cars it is nice to have if you run carbs or non-stock fueling and want to know if something is out of adjustment.

Nice! My clock has NEVER worked.

buttjoint · 02-02-2008, 05:00 PM

My clock works and I would still be interested!

Hester · 02-02-2008, 05:17 PM

Wow! That is beautiful. A real good upgrade.

Nice work there!

One thought: I've got the type of CHT that has the sensor at the base of one of the sparkplugs. I don't think I've ever seen temps higher than 325 degrees. Is it even possible to get 500+ degree readings, or would it make more sense to put in a gauge with a range more appropriate to our cars?

I've purchased all the stuff to add a fresh air duct to my clock opening, but I'll admit that I haven't been able to bring myself to get rid of the (still-functioning) clock. I find myself checking it all the time.

I read in on of your posts that you set the red line for when the session is over. I always liked that idea. I don't know why people hate the clocks so, it's pleasing to me. The glare is always on my radio and I have to take my eyes off the road.
