umm just quickly on your inlet manifold, you might want to think about keeping each center runner individual or joining to their respective secondary runner, instead of how you have it converging into one.



Just a thought the bridge looks great though.
oh yea i just thought about that it needs longer pulse width, good point

some dimensions i took on the housings , i want to join the 2 hoels on the NA it only seems appropriate for teh size port that it needs to flow. i also measured the FD for comparison.

i doubt it woudl eb such a good idea, since the pulses will be "lost"

but it coudl still amke mroe power just from the shear volume

little update on what i have decided to do. connected the bridge and the secondary and aux ports, also joined the port opening at the manifold side, and i am not gonna bridge the primary anymore but just do a large streetport on turbo plate.

That's a very cool idea, but I would be very worried - the length of that bridge, looks like it might break!!

yes it is, i am not going to cut that support just because of the lenth of that port.

i was thinking about also leaving one under the water seal area bu ti am not sure if i need to.
