Gauges . . . or instrumentation if you will

Thanks Bruce that's most helpful. I'll proceed with buying and installing new 'classic' style gauges.

What is the consensus on the speedo? Keep the original installed but disconnected?

In many ways if you have to carry it around with you then you may as well have the speedo working. If correctly calibrated can be useful for pit lane speed limits, but if you end up running various diff ratios or tyre sizes for different events and circuits then it wouldn't be easy for an original mechanical unit to be accurate for more than one combination. There is a Smiths classic styled electroinic speedo, it uses a wheel speed sensor for it's input and then you simply need to calculate and keep a note of the calibration figures for the various combinations of tyre and diff, but although classic styled it does have a small LCD display in the centre.

If that's an acceptable solution then it definitely makes sense to use a classic styled electronic speedometer in the long term. I think that's answered all of my questions so thanks again!

There is no requirement for a speedo in the HSCC Historic Touring Car regulations for cars running to HRSR specification. However, if you compete in that championship in the Appendix K classes then the App K regulations must be adhered to. But, as Bruce says, you are unlikely to be picked up if you run App K but with electronic instrumentation, non operating speedo, etc., provided the requisite instruments are there.

keep the speedo if you're considering road use obviously, but otherwise unless its an integral part of the dash ( and on a Cortina it isn't) loose it.

oil pressure, water temperature and RPM are the 3 most important, in that order also . . . and a big orange light to go on at 25psi if the pressure drops . . . .

this thread is old . . . I was still keen when it started!

If you want an accurate Smiths replica two needle electronic rev counter licenced by Smiths look no further than Farringdon instruments we do 3" 4" 5" and one offs.
