Header pipe heat range.

Not sure on the actual temps, but think the type of material (stainless or mild steel) and or the type surface finish, such as chrome/ceramic coating would have effect on the temp of the actual headers. also sure someone like Murf or Reg might know what the Exhaust Gas Temp (EGT) out of the cylinders would be? Which would also vary with the Octane rating of the fuel being run and the mixture setting possibly?

What were you going to do with the IR Thermo? and is a fitted or hand held version?

I hear ya, I don't mind that kind of gear either. Let us know what you find out, and based on what type of fuel.

As I'm interested to know what type of performance difference there is between running Premium 95 Octane and say Unleaded 91.
 
650° C should do if they ever get above that pretty sure they will be nice & red!!! :shock:

850 Degrees maximum a lot of drag racers use this method for tuning there mixture set up temp should be taken as close to the exhaust valve as you can get and if your KAT is the rare diesel version your looking for 700 degrees. Cheers Murf
 
Don't see why not Dave, I have seen others that are supposedly "Industrial Quality" for 5 x times that price, sure it is the same technology inside.

But on another note, this one has got me thinking about fuels, I have been running my 1100SD on BP 91 Octane, interested to know if anyone is using 95 or 98?

Cheers

I have both the IR gun from Snap-On and the Vacuum Gauges for the intake as well. I find it better to check visually the spark plugs and the vacuum intake settings to be more informative than just the heat on the headers. As there as too many reason why it can be cold or hotter than the other pipes.
 
Okay, well the tool I purchased only cost me $140.00 from Snap-On so as a guide you should be able to pick one up for half and still be a quality tool.
