rasco Posted April 14, 2015 Share Posted April 14, 2015 Si I've bought Defi "Racer" boost and oil temperature gauges. Couple of issues re fitting and location. Where do people normally locate their oil temp sensors? I've read that a sandwich plate is the easiest option, but I've already got one fitted for the car's oil cooler, and wondered what the long-term effects of using two sandwich plates are. I found a thread from a couple years ago where Keyser had done exactly this. Has anyone had any bad experiences doing it? Sandwich plate here: http://rspec.co.uk/gauge-sensor-adaptors/oil-temp-pressure/oil-pressure-temp-sandwich-plate-adaptor-m20-x-1.5mm There also appears to be a small screw above the sump plug, I assume I've got an HKS sump, as I've got a single HKS turbo, (the car isn't with me at the moment, so I haven't been able to look for myself), anyone tried putting a temp sensor there? Apparently there may also be a place to use on my turbo feed oil restrictor. Not sure if I want one there though?? Also, the defi sensor is 1/8PT (not 1/8NPT).... anyone found this to be a problem with the sandwich plate etc? Thanks! Quote Link to comment Share on other sites More sharing options...
mouthwash Posted April 14, 2015 Share Posted April 14, 2015 I have an oil pan spacer which includes a temp sensor port for my supercharged one but not sure it will be any good for you as you may have a different sump? https://conceptzperformance.com/Cart/description.php?II=2144 Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 14, 2015 Share Posted April 14, 2015 The sump is the best place as you get a more stable and overall oil temp, fitting somewhere in the pressure side will usually reflect the temp at the point of the sensor which can vary quite a lot.. 1 Quote Link to comment Share on other sites More sharing options...
rasco Posted April 14, 2015 Author Share Posted April 14, 2015 I have an oil pan spacer which includes a temp sensor port for my supercharged one but not sure it will be any good for you as you may have a different sump? https://conceptzperf...ion.php?II=2144 Cheers for the reply Yeah I've not looked under the car (can't at the moment!) but would assume it would have a larger sump already. No spacer fitted already by the sounds of it. Looks like this screw above my sump plug is the best bet then? Looking at photos of the standard sump, there's no screw there, so assume its an HKS sump specific..... and I can't think of any reason for that screw being there other than for a sensor.....?? Need to find out what adaptor I'll need for this 1/8PT sensor....grr. Quote Link to comment Share on other sites More sharing options...
ianp3k Posted April 24, 2015 Share Posted April 24, 2015 Currently im using two sandwich plates, no leaks as of yet On the road oil temps read 80-90C On Track 110-120C I may be wrong but i thought best reading would be to have the sensor in oil flow before its about to be pumped around the engine rather than sat in a sump waiting to be used.
