Boost?

[v8Stroker]

How come the new 6.7l doesn't run as much boost as the 6.4l or the 6.0l? My 6.0l has seen 35 pounds when I was towing on a stock turbo. Now the 6.7l uses around 25? Can somebody explain that too me?

More efficient turbo maybe??

More efficient turbo... multi injections... giving the competition a chance..???

Boost and power are not directly tied to each other. They are related in a turbo diesel but can vary greatly. Even though its "only" 25 psi, its very likely still flowing more air than a 6.0 at 35. CFM is what is important. Boost is more or less just a measure of restriction.

my sentiments kerzactly.. now just think about the power when the turbo gets pushed to 35-40 lbs by a tuner.. gonna be AWESOME!!!

Yea, it's kind of like this:
There's 55 lbs of air in my 35" truck tires, but 60 lbs in my bicycle tires.

More pressure doesn't mean more air.

Good comparison.

Is the truck faster, is it more efficient? Yes and Yes so who cares how much boost it has...
