I don't know what manifold you would be using, but I think that 38mm would be a little small for the secondaries (plenty for the primaries).
I saw a couple builds and they both were using 3 48mm TBs, one for the two primary ports and one for each secondary port.
3 44s would probably be sufficient.
This flows about the same as 4 38s, but the flow into the secondary ports is a lot higher than the flow into the primaries and needs the throttle sizing to be correct. |
