Series 60 Headers

I have to partially disagree on volume driving a turbo. Drive on flat ground at 1400RPM then start pulling a grade at 1400RPM. What happens? Boost goes up. The only way the boost could go up is if there is more air being pushed into the cylinders (as RPM hasn't changed). The only way that can happen is if more heat is being made in the cylinder with more fuel. More heat drives the turbo harder, pushing more boost into the cylinder.

Now if we were talking about a Roots blower then yes, more RPM equals more air moved.

 

We run Stainless steel double tubed water jacketed CMI manufactured headers on my buddies twin 10-71 blown 1200s in his 38 Cigarette.

There is Impacts like you Read about when your jumping off waves and landing at 90 plus.

They rarely crack and that happens from them being overheated and the double tubes move at different rates.

Also the tubes are paper thin compared to what you could use for a truck .

 

Boost is building because the throttle valve has been opened allowing more air in hence more needs to get out

 

If you say so.

 

No throttle valves on diesels. More fuel is injected. Intake is wide open all the time.

 

My bad.

Explain then how 1400 RPM standing still (not driving) doesn't equate to the same amount of boost at 1400 RPM with your foot on the floor, pulling a grade? The pistons can only displace so much volume so obviously the only way to increase the volume flowing to the turbine in the turbo is to cram more air into those cylinders. The only way that is going to happen is if you first increase the speed of the turbo. The only way that can happen is if you step on the pedal and command the injectors to deliver more fuel. Commanding fuel or RPM makes no difference as the end result is the injector puts more fuel into the fire. More fuel into the fire means more exhaust gasses being forced through the turbo to drive it and force more fresh air into the cylinder to support the increased fuel burn.

Your comparison of a hydroelectric turbine is a similar concept but not accurate in this scenario. Water simply travels downhill, through the turbine and on its way. The turbine isn't trying to boost the water pressure. Its simply capturing the kinetic energy of it travelling downhill and converting it to a rotational motion to drive a generator.
