Q. How much boost and power do you set up for along with Max EGT?
A. We use 9lb and a torque gain of no more than 30% and an EGT of no more than 500°Celcius under prolonged full throttle usage. My staff and I have seen many turbo kits installed exceeding these parameters resulting in severe engine damage. Use of chassis dyno is mandatory before and after fitment of turbo.
Turbo-Glide: Q. How much boost and power do you set up for along with Max EGT?
This statement is from Turbo Glide web site FAQ, they state 500C as the max temp, in this answer they do not specify pre or post turbo but in other answers they reference post turbo so I assume this is post turbo. 500C is 932F a general rule is post turbo equals 200F less than pre turbo so 1132F.
So the big question is, what constitutes excessive EGT? If everything is working properly, 1250º to 1300º F. is a safe turbine inlet temperature, even for sustained running, mile after mile. Above 1300º F. things can start to get edgy. Remember, excessive EGT damage is cumulative. Over 1400º F., you're usually gambling against a stacked deck and it's only a matter of time until you lose. The higher the EGT, the shorter that time will be.

This is an answer that Banks posts on their FAQ web page it is long so I copied a short quote if you want the rest follow the link.
They address the pre post turbo EGT fairly well in this FAQ.
I hope this helps.
