boost vs. egt

[kc0stp]

NA= 19.44:1
7psi boost= 28.7:1
10 psi boost= 32.66:1
15 psi boost= 39.28:1

Just for grins heres a comparison to my mild elevation of 1mile above sea level

NA = 18.40 :1
7 psi boost = 27.16 :1
10 psi boost = 30.92 :1 (current wastegate setting)
15 psi boost = 37.18 :1 (most likley wastegate setting post intercooler)
20 psi boost = 43.43 :1

And with that I agree that if your bolting on a turbo do headstuds at the same time, its a cheap guarntee to never have to worry about boost pressure (no one has blown a headgasket with properly installed studs) however to play devils advocate the "safe" boost level without studs is still debated, some have blown at 7psi others are running 20 with no problems (Ill also admit I dont have studs currently but I bought the truck post turbo install and pretty sure the turbo is pre 2000 install)

This thing was done some time ago, I need to run it some more and see where it's at but the egt looks like a little more fuel is available .
I have been looking for a thread dealing with egt vs boost vs fuel settings... not finding much.
Question , if I put another 150° of egt to this will boost go way up?
It sounds like its running like banks designed it, 5-9 psi if I got the story straight from the tech guys.
thanx cb

Boost will go up, until you get to the point of over speeding the turbo and losing power, but I like to think the pyro will let you know a little before that happens.

so I'm cleaning up and find the cdr holding a load oh h2o an oil,,, waiting for it to dry out before I test it,,, would short cycling the oil cause the condensate to migrate to the cdr ,I would think the vacume should have pulled the vapor into the eng,???have seen this in the umbrella valves on a ******* before, ,,, any thoughts
