over 1600 for a long period and your at risk of melting something

I do not sustain anything over 1400* It does depend on where you have your probe though. It should be in the exhaust manifold, some put it in exhaust after the turbo. If that is the case then I would stick with 1200* max sustained.

I have been as high as 1700 for a brief second racing it... around 1000 and you should not worry at all IMO. X2 on probe in exhaust manifold.

The dmax was built to sustain a 1300 degree max sustained egt. Depending on how long you are higher than that depends on how bad it is.

1790??? jesus.....

i would have figured that water/meth would have helped more than that

straight water helps but when I mix it with Meth it is around the same but pulls harder.

How long is too long. I was playing around doing a boosted lauch and around 80 to 100 it pushed alil over 1600. So a few seconds or how long?

I don't think you are going to hurt it in a few seconds. I would not keep it there too long though. Maybe 20 to 30 seconds would be safe. I have held mine at 1400 for a few minutes pulling some hills with the 40 footer in tow.
