Can anyone give me any part numbers of sensors they've used sucessfully? Max rating would need to be 1000/1050 Deg C or so I guess.
I'll be driving and measuring it using some custom jiggery-pokery similar to the ScoobyMonitor.

They supplied me with custom made 310 s/s encapsulated Type-Ks complete with s/s compression fittings, 2m glass braided cables with miniature plugs for about £14 each, they are custom made so can take a couple of weeks but the service is excellent.
Their part numbering system is quite daunting, but I can provide the part numbers I used for EGT and Inlet T/Cs if you need them.
Speak to Mike Bonnell, mike@thermodata.co.uk.
No connection just a happy customer.

go on the site, make up your own part number from the pdf sheets.
You want a 310 stainless sheath, about 300mm long, with 2m of glass fibre insulation.
Depending on how you are going to mount you probably want a 1/8npt compression fitting in stainless.
If you get a 1.5mm diameter probe, you can drill a 1.5mm hole through some thick part of the std headers and secure with exhaust gum (as per Andy F). Or fit with compression fitting welded to up-pipe, or fit compression fitting to lambda boss in headers with an adaptor, which is the same as the adaptor used for the oil pressure switch on the block.
Get with a male mini-plug and it will fit most hand held indicators.

The Thermodata part number for that would be:
TC MI FLK JG D15 SL0300 SM310 PP1 LL2000 LIL4 TT3 FF2
This is for a grounded junction Type K with a 1/8bsp compression fitting in s/s.
Personally I bought a 75mm one as the uppipe is only 50mm diameter. My uppipe already had a 12x1.25mm boss on it, so I cut down a bolt and drilled and tapped it to take the compression fitting.

300mm would be more suitable if you're fitting in headers, means cable doesn't run past exhaust.
although a short stubby one with stainless overbraid cable would be okay IMHO, potted area might need a little glass sleeve.
not everyone can just drill and tap stuff, which is a drag.

getting hold of NPT fittings and taps is also a PITA in England - best stick to BSP where you can.
I have a reasonable selection of Father-in-law's taps & dies
I should really return them to him...
