Default CSX 2431 Dash

Hi Guys.

After any close up pics of CSX2431 dash layout with gauge sizes as it looks like Ken Miles used a different Tach to most.
It looks as if the speedo is 3 3/8 but are the others 2 5/8 oor 2 1/16?
Also not sure of which ones used Fuel level, fuel pressure, oil pressure, ammeter, Water temp ??? etc.
Have scourered the net but hard to read detail on most pics.


Thanks
Brett

The small gauges were 2-5/8", with a fuel pressure gauge. I don't know whether they came with a Stewart-Warner or Smith tach initially, but Gurney's car had a 90-degree Sun tach as raced. As of last year, someone was making a reproduction of the Sun tach. Apparently, the Sunpro is currently unavailable, but there's a Bosch unit that's similar.

I think 2431 had a large diameter Smiths tach.

Looks like a Smith's chronometric tach to me.

I agree. Large diameter Smiths tacho.
On the Shelby American Collection website ... https://shelbyamericancollection.org...dster-csx2431/ ...under the heading “The Ken Miles Car” the tacho is described as "The big Smiths 'tell-tale' tachometer rotated so it was easy to read at high rpm"



Cheers,
Glen

...for as long as it was working. I've run a couple of these in restored cars and they are extremely complex, slow to respond (they move in 'jumps', not smoothly, following the revs rather than showing them instantly), and very fragile!

Smiths Chronometric mechanical tachometer. This tachometer movement is very much like a chronometric watch or clock and has been used in everything from production motorcycles to Formula 1 race cars. It is a very accurate method of gauging engine revolutions and some of the various models used had a resettable "telltale" needle that recorded the highest rpm the driver reached. If you look at most Formula 1 race car instrument panels you will notice a Smiths Chronometric tachometer being used, maybe even as late as the 1980s. These tachometers were available in different drive ratios depending where the tachometer was to be driven from, crankshaft (Cobras), distributor, camshaft, etc. . SAI transitioned from the SUN electric tachometers on early and up to the first couple of FIA competition 289 Cobras to the mechanical Smiths Chronometric tachometers. Depending on the particular model these can be expensive, STACK makes an electric tachometer that has the appearance of the Smiths but is electrically operated and has "telltale" capability, in fact they even reproduced the needle movement to mimic the Smiths Chronometric tach.
As per the statement above regarding "following the revs", all tachometers follow the revs, that's what tachometers do. Mechanical tachometers are more instantaneous than electric units.
Clocking the tachometer or any gauge for that matter is done so that it is easier to notice through your peripheral eyesight vs directly taking your eyes off the road to look where gauge needles are pointed.

Agreed on the Stack tach. Their ST230C is one I considered. It's a 5" so might suit the look your after.
ST200C & ST230C Classic Tachometers

Cheers,
Glen
