Turbo
Just curious, as this is my first diesel. How much boost is the gauge supposed to read when at max? Meaning, if I floor it should the needle bury at 4? Mine never gets past exactly half way. I'm asking because I went fishing with a buddy in his 6.4 Sunday. I noticed that up some of the canyon roads his boost would nearly max out on the gauge.
Again, rookie here so thought I'd ask. Thanks.

Have you gone over Parley's yet with a heavy trailer? Seems like I remember you were going to do that. That is when you'll have an opportunity to watch the truck work at max output. About 2,600 rpm with 22 psi boost. Wow. That is where you really feel the 400 horsepower and 800 lb ft of torque. Mine will accelerate like mad at the top with 11K lbs on the back.

I can't get more than 22psi on my turbo. I've tried. I suppose we are just limited to that for some reason. I have to admit, it would be nice to get 35psi at lower rpms so I can avoid the 3K rpm shift points.

The one on your 6.7L is designed for a bit over 30 PSI. It doesn't take 40 PSI to make 350/650 out of the 6.4L; it takes that much to do so while meeting emissions laws. The SCR emissions aftertreatment system in the 6.7L doesn't require such a high amount of EGR, so a smaller and more efficient turbo system is possible.

From: at the truck pulls
So, if the block stays together there could be some massive gains with aftermarket turbos and increased boost. I can't wait to see the guys doing Pro Diesel Truck pulls to venture down that path.
