Getting hot after Dawes needle and 3"

Make sure the test drives are at highway speeds as I found that you can open the needle valve too much which will give you great torque down low but at 80-100kph there was not enough bossy and power was terrible with high get/water temp.

I'll give that a go tomorrow

What happens if the car sits idle for a while? After its reached operating temp... Try removing the valves and put it back to stock maybe, and see if theres any difference.

Do you think you may of cooked something at 122C

Doesn't the Scan-gauge have an audible alarm like
my Ecu-Talk, that will sound an alarm @ 100C ??

You'll have a better idea whats going on when you have
the all your gauges fitted.

It's sits perfect 85C at idle. I might pull the valves and see what happens

There is definitely something else at play here.
Noticed nil difference after egr block, exhaust fitment or tillix kit.

I'm thinking possible air lock but these things are good for self bleeding.
Whats the overflow doing when hot?
Filling up?
Have you got the caps the right way around?
Normal cap on radiator and pressure cap on top tank??

I had the radiator done before xmas done two trips since with no overheating issues whatsoever. Just since putting the 3" and Dawes etc. Got today off so will fit up the egt been driving in the burbs and issues aren't there gotta find a hill and a 100k zone near home

A bit of a mystery thats for sure, cant see it being anything major.
Do one thing at a time so you'll know what is causing this.

you have the air solenoid looped off at the air filter?
cant see that doing it though

still thinking false reading, only because there was no steam
or boiling, from reaching 122C

Yeah but both gauges skyrocketed. Unless the sensor is faulty

Doubt sensor would be faulty eh.

The things that are sent to PHARKIN test me! The dump pipe has two spots to potentially put the EGT gauge. Reckon either of the bloody bolts will budge!!
