My replacement unit will max out @ 100psi and gradually drop to 80psi once the oil temps get to 200 degrees. Until that point I more or less ignore it.

Ive had 2 crap out and had very poor customer service from prosport. First one lasted about 2 months or 700 miles. It would startup fine then sit at 0 the whole time. I checked all the wiring and everything was fine. Called prosport and I was told that I would have to cover the shipping to have them check it out. Sent everything to them, received a call telling me that its fine and I don't need a replacement. I told them I'm positive its bad and convinced them to send me a new sensor and was given new wiring just in case. I payed to have everything shipped back to me and when I received the package all that was in it was my original gauge and sensor, no new sensor or wiring. Called them again and they sent the new wiring and gauge. I replaced the sensor and wiring and triple checked everything. The new sensor worked for about a week. Contacted them up again and was told it was my wiring and its basically my problem, so much for honoring a warranty. I quadruple checked the wiring and had a master electrician/ installer check everything out and found that the wiring was fine. I'm DONE with prosport. I have since removed all the prosport gauges from my car.

I am currently on my third oil sender unit from pro sport and it just stays at 80 to 85 psi all the time. works sometimes. They warranty the sender units for only 1 year, but make you pay for shipping to and from to have your unit verified bad. You think by now these Brainiacs would figure out they have a bad design and come out with revised better sender but nope. Heat may be killing it but its a pro sport sandwich adapter so if they know the heat kills them you would think they would tell us all to mount and tap them to the oil sending unit on top of motor.

might try the "wrxtra" oil adaptor for $45 and a new sending unit for $40 or just get a better gauge?

I'm on my 2nd sending unit and it just started screwing up the last week. Pegs the gauge on startup and stays between 60-85psi all the time. Even with the engine off the gauge reads 60psi after it does the opening ceremony. I'm going to try one more and if (or when rather) it fails I'll just bite the bullet and buy a quality gauge like autometer. I've about had it with this ebay ****.

My oil pressure gauge bounces between 100-110 every second back and forth. Is that normal?

i have mine tapped into the top of the motor (read pain in the butt to install)

usually mine reads correctly. 100+ when cold then 20ish at idle and warm.

go out to day to datalog a pull in third gear. 2000rpm to 6500rpm.

get back and park. gauge reads almost 0psi when at idle yet moves when driving.

now continues to read 70 when under load and under 10 when idle.

checked oil level and its still full. so i think the sender has gone bad. what do you guys think?

I replaced my OPS because it was doing the above. The new one behaves the same way. (Also installed same location with a short spacer to get tools into that area)

I am now suspicious of the gauge. But would like to remove the new OPS and plug it in to air compressor line with hand held regulator to control pressure to truly determine which is more likely at fault. Plus it would give me a more realistic measurement of what the sensor reads versus the gauge inside the cabin.

mine failed catastrophically and was gushing oil out of the terminals, wife was driving at the time and didnt know anything happened until the gauge started bouncing around due to no oil in the engine, looking at a possibly screwed motor now

After about 2 years my Prosport Oil pressure gauge has started acting retarded. It will get to 80psi, then bounce to 100psi, back to 80psi...over and over.

Guess it's time for some nicer gauges.

I think it also depends on location of pressure sender and how well the exposed wires are protected. I applied heat reflective tape on the sender and protected wires using dielectric grease.

My pressure gauge is reading 21-23psi once car warms up, which seems a bit low.

where it should NOT be, next to the header, regardless though it should not have split and dumped oil everywhere. I finally made a extension hose out of 5800 psi flextral hydraulic hose, overkill but its the kind of stuff i have access to.

Pressure sender under TMIC and temperature sensor under alternator... I wouldn't use filter adapter as it's prone to leak...

Prosport keeps telling me that 99% of the time its cause its not installed with clean seal and the gaskets are not being replaced every year (users fault is pretty much what they are saying) and that they have been using it on there 500hp sti for four years with no problems so im not sure what to believe

And this won't set the oil pressure light off? I probably would have gone with the adapter plate but I think the timing belt covers going to be in the way since I don't have an oil feeder for a turbo, though I was hoping i could have used that plate as one if I ever decided to go with an avo kit

I also think the plug where the intercooler would be has to many things in the way on mine
