Anyone have an aftermarket oil pressure gauge?
If you have an aftermarket oil pressure gauge, where did you tap the pressure sensor and what kind of readings do you get at idle, 2k RPM and 4k RPM? Mine is reading something like 10 psi, 37 psi and 60(?) respectively. The idle number seems way low.

Mine is in bars, a defi bf, at idle about one bar (14.60 psi), at 4k, 4 bars (58.4 psi) and sometimes it actually goes close to 5 bars in high revs (73 psi is 5 bars).
Your sounds about normal, idle is so low on mine that the alarm kept going off so I had to adjust the alarm down. |
oh I tapped mine at the oil filter with an oil filter sandwich plate
|
Check this thread for the oil filter sandwich piece.
I also posted on there the spec of what the pressure should be at 3k rpms. Mine is defi also but it's in PSI. |
The low idle oil pressure may be why the OEM oil pressure gauge acts like an idiot light--the normal range of 10-90psi would make ignorant users think something was wrong with their car if the needle moved that much.
I have a greddy oil pan coated in thermal dispersant. Under normal driving the oil temp averages 50 degrees cooler than the water, which hasn't gotten above 200 degrees F. I don't know how much of that to attibute to the larger oil pan versus the thermal dispersant. ________ Washington medical marijuana dispensary |
The thermal dispersant may be helping. I am turboed with the greddy oil pan and i have never seen my oil temps above 205 and that was only once. Most of the time around 180-190 unless boosting a lot. Not sure on my water temps, don't have anything to measure it yet except the stock gauge.

Tell us more about this thermal dispersant -- how was it applied, who can do it, how much, etc?

"Thermal dispersant" is a fancy term for shedding unwanted heat. I know of two ways that its done:

Additional data point regarding thermal barriers: I happened to have the car up on jacks tonight so I used a temp probe on the exhaust system. This is about 20 minutes after normal freeway commute driving. When I stopped the car the water temp was 190 degrees, oil was 150.
20 minutes later the ceramic coated exhaust manifold registered 300 degrees on its surface. The downpipe (also coated) was 275 and the Rotary Performance cat pipe was 210 just before the cat. Take that for what it's worth. If someone with a turbo and pyrometer could measure their temps it would be an interesting comparison. ________ How To Roll Blunts |
Where can i purchase the oil filter sandwich plate for an aftermarket oil pressure gauge, or is there a package available somewhere?

If it's not listed on their site, just email them and they'll respond. |
Google oil sandwich... there are many US sites selling them.
I have a spare one if you are interested but the cost of shipment maynot worth it. Let me know. |
Mazdaparts.com carries it now. Gold pricing is probably $5-$10 cheaper, email him to get the discount.

The offical MS gauges take the pressure by replacing the bolt just below the oil filter with a bolt where the pressure sensor is embedded in the middle.
|
I'm still trying to decide between this and the oil temp gauge. Any recommendations? Right now I just have boost and egt.
|
My recommendation if gauge space is limited is to go with dual gauges. That way you could measure boost, egt, oil pressure/temp, water temp and afr.
Personally I consider boost interesting but optional. Oil pressure, oil temp and water temp are more important if you're worried about monitoring safety. The two temp gauges will let you know when the car's warmed up enough to step on the gas and when to lay off the gas 'cause it's getting too hot. Oil pressure is a failsafe in case you blow a line or something. ________ LovelyWendie99 |
