For those of you that have an Exhaust Temp. gauge hooked up, can you tell me what the safe limits are at WOT.

 

That would depend on your a/f ratio.I had mine Dyno'ed and my WOT a/f is a little on the rich side @ 11.9-1.In 100* + temps and the water temp @ 185*-190* mine will see approx 1300*F.
Cruising at 80mph on the freeway I see 1200*F.
At idle after it's warmed up i'll see about 800*f
Hope this helps!-Dave
