R33 Exhaust Temp Range

[bj_dove]

G'day all,

I Just installed an exhaust temp gauge in the car, but i cant seem to get it to read past the base number (500 degrees C).

Just wondering what sort of temps i should expect from a fairly stock R33, i had the gauge reading up to around 650 with a gas match under the probe, so it works as far as i know.

Also the probe is installed in the turbine outlet of a split dump, just in front of the oxy sensor.

Any ideas?

Cheers, Bart.

350 to 900 degrees C.

Cold day, idling after driving 350

hot day going up big long steep hill 900

cruisin in the hood 400-500

highway around the 700 mark

cheers for that, must just be something malfunctioning

Stop-start city driving between lights (not just sitting extensive idling) 500-550C

Extensive idling 400 drops to about 350

Steady state rolling on/off throttle to stop, up to 80km/h not running big throttle 550-600C

Highway running extended closed loop running 600-680C

Climbing mountain range, mild boost 600-650C

Flat knacker acceleration run 700C

Thermocouple placed in split dump, main dump from turbine just behind O2 sensor.

Some of the cast HKS RB manifolds have a port at the collector , will get faster reaction times if placed before the turbo which does absorb some heat . Some tuning firms like to have them closer to the exhaust ports (by 6) and can help assist tuning on an individual cylinder basis . EGT tells alot about AFR but finding the variation between cylinders is impossible taken at the collector . The laser temp sensors would be handy at the tuning phase .

Cheers .

Can anyone tell me what the resistance of the sensor is cold? I'm hunting a problem at the moment and i'm leaning towards either dead sensor or damaged loom as i've checked everything else.

cheers
