How about volts and exhaust temp since that's an instant indicator of a lean condition?

Here is the volt tach. Usually there is a zero as well, this customer asked to have it deleted.
They are $235 with your core

unless you have extra extra oil cooling a CHT is a 5-10min heads up on oil overheating. I use it often in the Rockys' or even coming into LA from the N on I-5 during summer heat. My usual routine is to just maintain speed in 4th gear instead of 5th when CHT starts to rise. It'll also clear up any confusion when running in 110F deserts between inadequate or ok oil cooling.


CHT is also a great indicator during cold winter warm ups.


EGT is a great tuning aid for carbs if it's a digital read. It'll also show the difference between a miss caused by a fully clogged jet w/its dead cylinder and a partially clogged jet running 1,500F+ lean.



IMO the volt meter and CHT is a nice set of tools and the EGT is unnecessary with fuel injection.


...... different strokes for different folks

Who is going to mount an ignition oscilloscope in the dash??

I can't remember seeing...
was there a combination volts and mini-clock that could be put in place of the "big" clock?
this would add the volts function and still keep the clock function... the current clock is bigger than it needs to be

here is approximately what I was thinking re. volts and clock combination

probably any relationship would work... flip top to bottom or go side by side

Interesting,
Maybe this could work. VDO has some pretty small clock packages

Great idea hcoles, I like that better than the volts in tach, Let us know Mark. Very cool.

I hope this is not too much brainstorming, but is there a vdo clock (analog) that is small enough to be inserted in the tach instead of the VM. I am thinking about symmetry of the dash, albeit maybe too much... I like the early silver center caps, and so I would rather have all 5 gages with the silver cap in the center, meaning, you would have the have the stock clock replaced with (probably) the dual sweep gage. I guess the other alternatives would be move the clock to the center console, which I am leaning toward at the moment, or nixing the stock clock and inserting an amber LED clock in the bottom or side of the tach (depending on the number orientation you use on it). The more I am thinking about it as I write this, I kind of like the idea of an amber LED clock in there. It would still be a vintage feel I think, being that my stereo has an amber digital display. The amber LED clock would probably be a lot cheaper as well, I would think anyway. What do you think Mark?

The only problem I see with the amber LED as I think further might be the ability to see it in certain daylight conditions... may not be a problem for those with coupes, but I have a cab.

Mark, any links to vdo smallish clocks that might work? I googled a bit yesterday and didn't come up with much. I think all I need on the small clock is a black center/adjust rod and orange "arms". For the volts... black center and orange arm and white letters...

My tac and speedo are the type of black center with the orange arm line that goes all the way across the center of the black center and then stops... no overhang.

The only thing I don't like about putting the volts in the tac is I sort of like the idea of keeping the tac unfettered and "pure" - that's just me... other than that I think great ideas and workmanship

I found this vdo clock.

It says 52mm OD.. I would guess the pointers would be less.

Maybe it is the same as the "full" size clock I have. It doesn't have to be VDO if the characters are printed on the front face and the "workings" are in the back. Just the color of the pointers need to be close to the tach and other gauges... then all we need to come up with is the volt meter approach.

What about something like this (to illustrate my idea earlier)...

http://forums.pelicanparts.com/uploa...1203713078.jpg

I like that... can almost use as a lap timer.... and saves the clock function.
Another idea to add..... bright yellow row of led's as a shift light...
Under normal driving, usually not working... works when on the track... adjustable depending on what engine you have and how hard you want to flog it that day.

How about a display, like the last one above, only you could hook any number of sensors to, (user selectable). If its just a numerical display, you could display anything that you could get a sensor for!

Think 5 channel input
Ch1 = oil temp
Ch2 = oil pressure
Ch3 = voltage
Ch4 = CHT
Ch5 = speedometer

Via a push button switch, you could loop though and view any one channel at a time.

CHT guages are popular on VW race cars because if you're really pushing the car, and there's a problem, you can do some damage before the oil gets hot. And you need one on each bank to catch the possible isolated problem with a single cylinder. Following that logic, I think a dual CHT guage with L/R bank monitoring would be helpful for guys who do a lot of races/DEs. Also, I think the hot side should be on the top on both guages.

FWIW: My clock works, and I like it.

I know... I'm the oddball.

Good stuff. Subscribing.

I just officially added this product, the details are on my updated website:

Thanks for all the input.

So, how much for the set up I have a nice working clock in my radio anyways

I would be interested in having a shift light integrated into the tach - is this something that is possible to do?
