It is important because? It lets you know that your engine is getting hot and is about to blow? Because the first sighn of an engine over heating is through the exhaust???

Anyone know?

 

its important for turbo'd engines. not for NA.

 

Well, a good temp gauge would allow one to adjust air fuel mixture on a NA motor also....

 

Explain.........

what kind of temp guage are you refering to??

 

Higher temps= leaner fuel mixture
Lower temps= richer fuel mixture
As for the target temperatures, sorry I
just cannot remember right now.
If I recall them I'll add more info.
From what I understand, the Autometer and such,
the ones under $150 just aren't accurate enough.
I'll go look around for more info.

 

i see
so would you use a air\fuel guage too or just teh exu. temp?

both, but wide band O2 works best.

 

I'm running a GReddy ETG with my boost set up and an APEXi Auto/Turbo Timer. The APEXi timer is nicer IMO, cause it also gives yyour air/fuel ratio.
