If one wanted to know about each cylinder, one would need to have a sender installed in each cylinder whether we are talking CHT or EGT. Mark's gauge is great as a replacement for guys who want a bit more info and don't have a use for a clock. It is what it is. It seems that many here are asking for much more instrumentation. Thousands of stock Porsches on the road do just fine with simply an oil temp gauge and an indicator light for the alternator. Mark's fine gauge is a step up from stock, but don't expect it to be a magic super computer. I guess everyone can have different desires for how much detail they want to know about what their engine is doing. I think Mark's solution is a pretty neat minor upgrade.

This may just be extraneous information, but EGT gauges are also known as pyrometers.

cashflyer, that is so correct! Almost every turbo equipped engine that I have had, either gasoline or diesel, has had a pyrometer. I have seen some that were positioned before the turbo, and some just after the turbo. The sensor after the turbo is the safer of the two. This is because, if the sensor decides to crack or break, the ones installed before the turbo, can do a LOT of damage to the impellers, while the ones installed just after the turbo, generally will not do any type of damage to the very expensive turbo.
I must say that the gauges shown look GREAT!!

From a functionality standpoint, I would rather see the oil temp and oil pressure gauges in the clock location. Even with a stock wheel it's tough to quickly check temp and pressure, but the clock is always easy to read. I would then place a voltmeter and EGT gauge in place of the oil readings.

I wasn't implying that his gauges were anything less than excellent. I think they're awesome. I think on his original post he was looking for ideas and mine was merely a suggestion. I agree the CHT gauge would be good for guys who want just a touch more info without going over-board.

Marks914....how much to covert the temp gauge to numbers instead of those vague lines?

Netspeed, probably just asking a stupid question, but I will ask anyway. Do you just "want" to know the corresponding temps, to the hash marks? If so, you can look at the gauge face at an angle, towards the center of the gauge set, and just where it just starts to be hidden by the faceplate, it has the temp degrees sort of hiding there. If you already know about this, please excuse my question. Tony.

I like the clock also, (still works). It's actually a conversation piece in the car. That being said those are gorgeous gauges and would consider oil temp. volt etc. Nice work.

Well, how about this question Mark (is that a pun?)...

If I were to have you install the VM at the bottom of my tach, I would be one of those guys thinking, all my other gauges look like crap now! So what kind of ball park to reface the whole set, in addition to the VM add-on? One other thing I might want would be the oil temp numbers liek someone else suggested. I think that would be great depending on price. One final thing I would want, and this is just thinking outloud, but a second set of numbers (maybe in a high vis red) at the bottom of the speedo, basically so a person could use the bottom of the needle as a secondary speed indication when you get in the range where the steering wheel obscures the numbers... just a thought.

I have the same dilema Jack. I really like the old analogue clock, gives the right 'period' feel for the car. The only time I really 'need' the clock is for judging how much of my session is left at trackdays, which is exactly the same time I'd like cool air blowing from a vent where the clock is now. Btw did you buy the Smart (?) clock vent kit or do something custom yourself ?

I usually charge $75 to put a new face on a tach or a speedo. I would charge the same for any gauge. That includes refinishing the trim rings, repainting the needle and replacing the lens if needed. This is using my vinly overlay. (seen on the tach above). The combo gauges, I do not have plates to do the front faces yet, but I can make them if the demand is high enough. I can do pretty much anything with the vinyl face, its the best option for price and customization, its what I have been running in my car for a couple of years now.

I can do a printed face in a single color. I paint the face and then print it (like on the quad gauges and CHT front face) for an additional $85.

To add virtually any VDO gauge to a standard tach is $150, that includes all of the above and the addition of the gauge to the tach. I wil try to get one together this week with a volt gauge installed to show you all.

to keep a clock AND the volt/cht gauge, why not use a 914 clock. it's the 2-1/8 size and could fit somewhere else on the dash panel. and would look 'right'. just a thought.

Ok, I just needed a moment to wipe up........


Love it, I've been debating about going with a Mark Big gauge, but it seemed more appropriate for 914's...... now is see this......


love it......

Sounds to me like there will be a glut of clocks on the market soon. ;)

I don't want to dilute Mark's thread, here, but I got the Ford truck vent that Wavey discovered in this thread.

I think it could be combined with the Smart Racing kit, or you could fabricate something similar to the Smart Racing kit (like Ove did in that thread). I was planning on feeding it with a marine fan and keeping it separate from the rest of the heating/cooling system.

Nice work on the gauges. I really like the quad gauge and the VM option in the tach.

Those two mods appeal more to me as I like looking at my clock. I really like my dash for the layout and design and the quad gauge doesn't mess with that like removing the clock would - it just boils down to individual taste.

Really nice looking work you've done Mark.

If you haven't gone to the link in Marks posts; the site shows a lot of options.

Want to keep you stock clock? Move it.

RarlyL8 has the right idea... the clock need not be "line-of-sight".....but any of the other gauges like a voltmeter should be....

Mark,

For the less-than-mechanically inclined on the board, would there be any additional connections necessary to support the voltmeter on a tach face? Or would the VM run off the same wires the tach uses?

In other words, could I unplug my tach, send it to you, have you put in a VM, and then simply plug the tach back in and presto! have a working VM?

I was able to adjust my valves, but I don't like the idea of cutting into wires for some reason. A mental block on my part I suppose.

Also, what is the turn-around time? A week? A month?

Thanks.

Like what has been said ; to be useful a EGT gage is the only thing that will re act fast enough to give any useful info.
A Eng. can climb a 1000 deg and back to "normal " ( all in a few sec ) W.O. hardly effecting CHT.
To be totally useful it would have to monitor all 6 cyl rather then group them into a whole .
