This is the TT intake runner internal design. Notice there's a V-groove pent roof.

This is the N/A runner design. Notice the ceiling is smooth as compared with the TT design.

Interesting, never noticed that.
probably casting mold since it's a one piece vs na two piece runners.
I was thinking they were vortex generators or something to promote swirl? They align with the valve divider in the heads so hrmm. I wonder if all versions of TT intake manifold have that design? What does your runner look like? Also, what's the total length on it? You mentioned some hood interference? Did you cut down a TT mani or use the N/A lower?Quote:

All the TT plenums I've seen have that "V".
Before I had TT runner cut out and welded a tank to it, but my new one is xg350 runner so it's a bit taller. The tank doesn't hit the hood, it's the runner right at the knee that hit the hood a little bit. I don't have the manifold here, but the runners are 10" long.Quote:

Would be difficult to bolt the rear cylinders down as it takes 2 bolts per cylinder, and would have to bolt through the runners.
Nelson. Plenum volume looks small. Requires new fuel rails. $3000. Not sure if it comes with rails. Too rich for me so I didn't ask him for more details.Quote:
