Here is my version of the intake manifold concept that you love to hate.
Compact, easy breathin'; made from 6061, welded up and heat treated back

to

T6 condition.  Welds are ground smooth on the inside, radius ground

inside

at runner junctions.

Second pic shows manifold and throttle body together.  Staged injection

with

primaries in the housings and secondaries in the TB

It is a work of art Al. Did you do it? Be sure to let us know how much
HP you get out of this. Is it turbo or NA?

No, it was done by Cliff Manzke, Manzke Engineering, here in San diego.  I
told him how I thought it should be done; he provided the innovation and
craftsman ship to make it happen.  Nice piece of work.  BTW; it weighs only
2 1/2 llbs.

We have a couple of extra flanges, and he now has the tooling if anyone
would like one of these.  Mine will be normally aspirated.

I hope to get this thing on a dyno in the next few months.  It will be very
interesting to see how this works out.

Attached is a pic of the engine with the intake and exhaust system.
