Our current P-port manifold and slide throttle weighs about 3 pounds.
2 pounds for the slide throttle and about 1 pound for two
2 inch dia. .065 wall aluminum runners about 16 inches long.

        How much HP will it make?

Looking forward to seeing your hand layed up, vacumm bagged, autoclave cured
epoxy pre preg intake manifold. Are you sure it will only cost
$900 ? :)

        How much will it cost to P-port the engine?

In theory and if we can duplicate what Mazda got with a
similar porting arrangement up to  320 HP at 8000 RPM.

Did you not get these three jpg's I uploaded a couple
of days ago?

Also there is a lot more info on:

My guess on P-porting once you have learned how to do it and
you can find someone with a mill is one half hour each
p-port hole in the rotor housing.

$50 bucks for slide throttle sheet metal parts and
$60 for two 180 degree tubing bends, $80 bucks for enough
Teflon from McMaster Carr to make four and what ever the
welder charges to weld it together.
