Best place to fit oil/water senders? impressions pros/cons

[Prodigy]

for people with FD's, why not tap the bango boot coming of the front cover?

Just like people do for the rear bango but before the oil gets a chance to go through the cooler (s) would that be a inexpensive option that is still fairly accurate?

I would think so, unless people have already converted to AN lines as part of an oil cooler upgrade. It'd be nice to see a port located at the oil thermostat (if so equipped)

So far they've threaded in alright. I'll have to look at them again. Now I'm just trying to decide if I want to move the water temp sensor into the stock port or keep it where it is. I figured the stock port might read higher temps since it's right next to the spark plugs (and I figured there was a reason Mazda put it right there), but looking at the coolant flow picture, it looks like the hottest temps are where I have it now, right behind the thermostat, and I like that.

Is it because of where the typical measurement location is (pedestal) which is after the coolers on its way IN to the engine that 210 is considered high? Because it assumes 230+ in the pan or as exits the engine directly after the pump?

I'm debating adding a oil temp gauge to my RX8 as it mostly sees track use, and am debating between a pedestal and the banjo bolt at the first oil cooler. If I put it in the banjo bolt, I'd imagine the scale of "danger" would shift to a higher temp.

I don't remember what my temps are during the summer (the car has been down since last summer lol), but during the winter I've seen as low as 109F and I've had my sensor in the oil filter pedestal.

As for what you're asking, that's hard to determine if they don't tell you where the sensor is mounted. I'd say just decide if you'd rather know how hot it's getting at it's hottest point, or if you want to see if the oil coolers are working so you put it in the pedestal (although you'd still be able to tell if you mounted the sensor at the front of the engine and one day you notice your oil is hotter than normal). Either way, decide which one you want, pay attention to it for a while to see what's typical and under what conditions, and keep that in mind so you can spot a condition should it arise.

I have AN lines and fittings already. But that's why I'm going to get the fitting Brian linked to. Otherwise I would think the banjo bolt is a good idea on a stock setup.

I wouldn't want the sensor bulb plugging up the middle of the bolt where oil needs to flow.

agreed, guess I should clarify... I just seen on 7 club a party about drill/tap the bango, and its in the way quite a bit, another poster suggested, drill tap for 1/4 npt vs 1/8not (or bsp depending on sensor) then swedging it to the sensor size, this pushes the sensor probe out of the way so it's not in the flow nearly as much as before...

I agree. I was even contemplating a PLX system which can tie in to the OBDII to show coolant from the ECU, and oil temp from the PLX on my phone (torque app). Their sender is pretty long, and unless it can be spaced out there is obvious worry of restriction.

Autometer has this:

Designed for cylinder heads but same range as the other sensors so it fits all short sweep temp gauges. Would work good in a standalone app where custom resistances can be calibrated in, or if using autometer gauges is acceptable. I didn't really want to add an actual gauge to the RX8 (down by shifter), especially since I use my phone to watch coolant temp already when at track days.
