my bad, your correct. but i think the idea is still there.

 

For the hater, idk what his drive pressure is though, or what the spring tension is.

Thats even worse than the others. Zero control over boost pressure. Then you have the exact same problem mentioned before, the turbo is choking the crap out of the engine's exhaust at low loads.

It also won't work on any but the first generation of VGT turbos, all now have holes drilled in the vane base to equalize pressure across it so they can use "low force" actuators.

 

Thats all I use and its worked perfect for 15 years.

 

​​​I used a two stage pressure regulator. Everything works great. The car is much more powerful, fuel economy is 25-30 percent compared to the wastegate turbine.
