It's enough that I am considering a blow off valve on the burb 20psi is way outside the map for that little banks turbo I worry about overspeeding it

6.2 What's it good for? Just about everything.

That was going to be my next question...how far do you push it before you start worrying?
I have heard that 15 is safe more then that is pushing it , both engines are studded so it's safe engine wise .
I'm not up on this stuff near as much anymore since I have gone back to having Cummins powered rigs for most towing and daily driving .
That being said , I still love my little basterd V8's

How high would you run boost on the 6BT?
A lot of a factors to consider on a Cummins but rule of thumb is 40psi or so on stock head bolts
Cool, that checks with what my buddy tells me. It's a whole different engine, eh?
Oh yeah haha , I have one of every generation . From a non intercooled first gen all the way to my '12 6.7
That's quite the fleet. Do I wanna know what the total count is?
Well I'm no where near @mountainexplorer levels but it's more then I can really count at the moment I have stuff in 3 states
I've got my new PMD with the #9 resistor. I am putting the boost gauge in next week, then I am going to bump the boost a bit and see what happens. Well, and stick in the EGT probe for that gauge also.
Are you gonna get some baseline numbers before you start bumping boost? Or just charge right in and start tweaking schtuff?
Oh, it will be left as stock as possible for a little while. Then just small adjustments. I want powerful, but efficient. I'm not trying to sit on the line of unreliable.
.....get yourself a carbon monoxide detector....
Uh, that ship has sailed. It's got full exhaust now.
Flame away... but after towing 7-8k with this motor I really don't think I am gonna be turboing this, it pulled ok on flat ground but any hill it has to be revved and left in 2nd because no way it would ever pull 3rd.
My main concern may be based on internet lore but I could not get the thought out of my head that I was gonna break the crank..
for this reason I am gonna skip the turbo or any 6.5 swap and either go cummins or efi gas. I'll drive this until something that major breaks and then swap it but for now it'll stay the go getter and parts runner/crawler wheeler. I just don't feel that this particular engine architecture will pull what I want to pull how I would expect it to within the realm of reliable..
I like to have some buffer of power reserves and braking, just in case.. I don't like to have to worry that I'll never be able to pass or get outa the way if I had to..

Harmonics break the cranks , replace the dampener
Smokey has 300,000+ miles now and 1/2 of that turboed . it has always towed heavy and had its guts worked out
I have replaced the dampener twice , both times was when it was showing signs of the rubber cracking

I have never worried about the crank breaking. Did your get hot?
That is my main concern when towing with a non turbo 6.2.

I have got Smokey very hot one time , wheeling in chest deep snow with a full cord of firewood on it hit 250 so Inlet it cool down and winched the last hill
I think the highest I have ever pushed is 225
Another one bites the dust, eh? 
I understand if you say you want more power, but if you leave it the way it is you may be waiting a loooong time for it to break. I'll echo the comments about overheating being the likely cause of future death.
How 'bout this...why not run the turbo until it kicks the bucket and THEN start thinking about a Cummins swap at that point. I'm not sure what you have to gain by babying an engine that you're planning on replacing anyways. Why bother having the truck if you're not going to run it?
