And we rarely get above 2000-rpm (heavy payload or heavier trailer and/or hilly starts or mountain grades).

I was thinking since you measure to length from the valve to a protrusion/hard surface to reflect the pulse wave you could build the intake similar to the exhaust. Build the mounting bracket to the heads then bend the first stage pipes till they all meet the same point where they blend together into a larger pipe and that pipe works its way back to the turbo making that the first surface it sees allowing for a longer runner length.

Literally it would be like running a tuned length exhaust manifold on the intake.

On an IDI turbo engine how does all the air get through the small holes in the pre chambers and what effect does that have on intake tuning?

None. You don't have to worry about the small pre cup hole until after the intake valve is closed.

Had a brain fart. Of course the intake valve isn't in the pre chamber.
Thanks

I think those pre chambers would be good for smoother starts and quieter running but I have a feeling they could increase pumping losses.
