6. Positioned snorkel with fingers cut into bottom of snorkel. I had to abandon the 'fingers' mod because these fingers flattened out and eliminated the nice bottom buldge of the snorkel (taking out a lot of the volume of the snorkel). Had cut out the whole bottom to build in length-wise ribs of SS rod, tacked with super glue, repositioned many times to get proper alignment to FM-200.
7. Snorkel with fingers cut into top of snorkel. These were bent down to the top of the glas ring, and tacked with super glue, repositioned many times to get proper alignment to FM-200. Eventually glased to the ring; as they were bent down, their ends came forward to the forward edge of the glas ring.
8. Bottom of snorkel completely cut out and ribs tacked onfor shapoe of buldge.
9. Early positioning alignment - note how the glas ring is not well aligned with FM-200 throat. Had to pop off rib ends and re-super glue a number of times to get the alignment right on.
10. Middle portion of snorkel has been cut out and has a few glas longitudinal ribs tacked on. I order to take out a twist in the snorkel body between the two ends I had to eventually do this. You may find no twist or a better way to do this. I first tried cutting some lateral cuts to make the snorkel 'accordian' to take the twist out but that did not work like I thought it would.
From here on, the process is many attachments to engine, un-tack stuff, re-tack stuff, twist and tug, then many small glasing patches of the openings in steps that allowed me to get to the inside of the snorkel as much as possible and to let the patches of glas to hang via gravity to form as much as possible rounded patch forms rather than faceted patches.
This is the orientation of the throttle body on the engine; it has to be this way because there is a sensing port on the stem (small hole just to the left of the center cone) that has something to do with regulating the fuel flow (from my memory of an explanation by Don Rivera). If that port is on the opposite side close to the sharp bend of air around the last turn of the snorkel into the throttle body, the fuel flow goes way down.
Here is the snorkel hanging on the engine.
The snorkel is attached to the throttle body with a 1 1/4" long x 3 1/2" I.D. piece of silicon reinforced hose (race car type used in the super charger zone). Bought a short piece on line from K&N (kandn.com); Cut it to short pieces on a metal cutting band saw. Stainless hose clamps (No. 60, 4" Dia) on throttle body and snorkel ends.
