is 1400 degrees gonna melt pistons?
My egt reads 1400+ at 10 psi. Is this too hot that its gonna melt pistons?

Where is the probe mounted?Is that at full throttle run or cruising?That doesnt sound too hot but I think alot of variables come into play.

when i start to accelerate cruizing. also, monitoring the peak and hold feature, EGT recorded was 1500+. AFR is about 11-12.

shouldnt the egt lower when your accelerating? and i dont ever think ive seen my friends tuned civic go the high maybe your running lean? my friends crusing on the freeway is around 1400 but flooring it lower to aobut 1200 or so, and by how hot the gasses are you can tell what your a/f ratio is.

Typically, if you keep the EGT's lower than 1550 degrees, you will be fine. Anything higher and you will be turning your block into a foundry. I usually try to keep the temps at 1500 and A/F around 11.75-12.5.
If you find that your A/F is good, but you have high EGT's, then your timing is in need of adjustment. I had a vehicle that had really high EGT's and ran rich on the A/F. I found that the cam gear has skipped a tooth. |

If its on the colector before the turbo, 1400F is plenty cool. What is it under WOT? 1600F is about as hot as most people want to mess with on pump gas. I've run my car as warm as 1650, but you better know your tuning is right. to me...1500F leaves a lot of extra room for error and you're still leaving some "safe" power on the table that you could be utilizing!
