jusr fitted boost prosport stepper gauges,

boost, oil temp and oil pressure

the oil pressure is runfrom the oil switch with the t piece,

the gauge is reading 3.5 idle and maxs guage at 7 bar when reved or driving

any ideas on why this is so high.

im thinking faulty guage or sender unit???

il fit a mechanical gauge straight into original pressure switch to get correct reading.

anyone know of any faults with the senders or guages.

car is a 52 plate bug eye uk wrx.

thanks matt

Those figures could be correct from a cold start. What are pressures when the oil temp is about 90 deg C?

3.5bar idle at warm is fine, 7 sounds a bit high for running temp though

7 bar cold - once saw 8 !

3.5 hot idle since oil cooler fitted.

it settles at 3.5 bar when warm but the as soon as u rev engine it shoots to max. checked all connections and wiring all is fine, run it from oil pressure sensor with the t piece.

themseems to work. im thinking possibnly faulty sender,

any ideas. im gonna put a mechanical gauge on tomorro to test.

any had faulty gauage or sender unit.

any way 2 test sender?

My son fitted Prosport gauges in his EVO IX and they were a pain! Replaced a faulty sender and all was well until recently when the oil pressure gauge started flicking between 60 and 80 psi - all the time!
They look good but I prefer my direct reading Mocal gauges - they work!

The PRV in the oil pump should open/regulate the oil pressure at approx 95psi/6.5 Bar,so quite possible the sender unit is faulty.

just put mechanical tester on on it read 5.5 bar cold, which is normal, and settled down just above 1 bar warm.

so seems sender unit is playing up
