I too find it comical all the people who want long manifolds to increase torque and spool.

That's why I was curious to see how Aaron Parker's spool turned out since he has those super long runners. I don't think I ever saw his dyno sheet, although it hasn't run just right anyway.

I have an EFR 7670 with 1.05 divided, short runners and as short as piping possible to my VMIC, including keeping the pipe between the turbo and IC at 2" so there isn't any pressure loss there. I was going to go with a larger pipe right away but the guy that fabricated the manifold and other piping for me builds race cars and told me to keep that pipe small, and I figured he knew more than I did lol.

Aaron said he did research on different race teams to see what their spool was like and that's why he decided on long runners, but now I'm wondering if he was looking at one that was NA. I hope he's not disappointed but I think he might be.





And sorry for hijacking your thread, Mike lol.
