Is this running lean???

[Big_Daddy]

Abit concerned... is this running lean? the tips loook pure white?

Or running lean does this cause loss of power or just chance of it blowin a piston...

 

[Big_Daddy]

in real life they look more white than grey.. the metal tip...

Were the plugs taken out after the car was sitting at idle?

so is that a ok colour?

Today i just drove today mix driving with bit boost..
Yesterday i drove it HARD :drive:

Its fine from driving at part throttle.

But if your going to be reading plugs you will have to shut the car off at full bore to get a reading from them to know if our lean or not.

Yeah, if you drive it at light cruise or leave it at idle the plugs will usually show a lean condition.

The only way to read them is to shut it off at wide open throttle.

Better to use a wideband for fuelling checks. Far more accurate.
