Im Considering fitting an oil pressure and oil temperature to the Exige, similar to what I did on the Europa. I made an 1/8 NPT boss and welded it into the sump for Temp and pressure made a T piece coming off the pressure switch on the back of the engine.
Are there any sutible locations to put the sensors without having to go to these extremes, or fit a sandwich plate off the oil filter. The car has the twin oil coolers if that helps.
Yus sandwich plate is probably the least disruptive, I did the sump option because I was fitting a baffled sump anyway (which you may want to consider if tracking) so it was as convenient to do that.
Another vote for vent mounting, much more usable place IMO than the gauge holders that dangle down from the dash.
So when it hits a set threshold does the the little red LED flash or the whole display screen changes colour? I am curious how noticable this is compared to installing a lage orange light on the dash top.
You can have either as far as I know, the way I have it set- the backlight itself flashes red (or any colour, could be green/blue/etc). The SPA gauge also has an option to send a signal to an external alarm too -so you could wire it into the stack gauges if you knew the appropriate pin-out so the OEM oil warning light comes on at a custom threshold, or even a buzzer/alarm if you’re that way inclined.
Only issue I find with oil pressure is that after a hot run, if you bring the car back down to idle the car is likely to drop to 1.3-1.5 bar anyway so you can’t set your threshold too high unless you’re happy for the occasional alarm flash at the traffic lights!
