whats max egt 97 12 valve

 

1200-1250 degrees sustained temperature, 1500-1600 peak egt for short time, any longer and your pistons will melt. I've seen a couple of trucks push 1800-2000 at truck pulls with both good and bad results. most of the bad results were with the dmax's.

 

thanks a lot im glad b/c b4 i had the gauge i got in a race and held her to 95 mph did that again with the gauge and had to slow her down round 85 so i know it got hot when i had no gauge

 

My truck has pegged an 1800 degree pyro at a truck pul once, as long as it's for a short time, high heat won't hurt you.

 

It depends whether your probe is pre-turbo, or post-turbo.

 

Its kind of like playing russian roulette. You can probably get away with pushing the limits once---- twice--- a dozen times--- 2 dozen times etc. Then .

 

my probe is mounted about 1.5 in from the head i drilled out the mount for the 2 heater pipes that run on top of the manifold [the back one] and installed it there

I think you are only getting one exh leg for temp there. It will probably be OK, but not as accurate as just before the turbo in either the front or rear port. Did you remove the manifold before you drilled and tapped it there? (I hope)
