Z,

Micke probably than it seems.

The "mostly stock" probably refers to his using mostly original parts like the rods heat exchangers, P&C's, and retaining CIS. Almost all parts including the fueling system were probably breathed on quite heavily and a very special turbo and cam were added to the mix.

Looking at his TQ curve it looks like a combo of a cam timing and pulling the boost back very quickly once the fueling limitation and the motor VE starts falling off. This is a guess.

I very much agree with the idea of working withing the fueling of the existing system including a high torque cam and active boost management that pulls boost back when the limit of the fuel system has been reached as solid approach.

J,

I do believe adding a wedge to the meteringg plate should advance the meteringg plate further for more fuel and be much simpler.

Stage two would be reducing the advance rate of the meteringg plat through a larger meteringg cone or less windage at the metering plate combined with a HF fuel head.

If the advance rate of the meteringg plate is reduced 20% and the fuel head delivers 20% more fuel, they will balance out and the stock WUR settings could more closely be retained. However, we still need to figure out how to get the MP to advance further and not stall which is what the wedge dose as well as relocating the hinge point of the metering arm.
