Let's settle this once and for all..
When I posted, there was only the top picture.
So I thought it was about the port holes.
My bad.
Sorry for the confusion.:eek:
Lol no big. that's why I thought I'd ask you again to look. :D I've known of folks drilling into those exh holes though the next size maybe 1/4 deep to make an inner ledge and hammering a small lead fishing weight then peening over the outer edge of the hole so they stay put. Drilling, tapping, set screwing is the most popular way though.
BUT... I did find out that if you fill the hole with clay, flush, as if the hole weren't there..the flow picks up a ton. Its sickening.
What happens is , well.. just blow into a cup and see what the air does. Crash and reverse. Makes it's own wall blocking the air its detour path. So to fix that one way to do it...would be to tap all the way 'maybe 98% down' to the ssr.. then you would want to knock down the 1st 4 threads from the tip to clear all threads and end up protruding at the bottom ssr side exit. You'd want it to jam in tight also and would be using red or industrial lock tite.
Then you could grind the nose down on the set screw to the rest of the turn.
Now I wonder if you could manufacture a short turn cap that had a hole at the top of its ramp...like right where the air port is on the floor of course.. if a really long tungsten set screw with threadless nose 'forgot the term' could be used as an anchor. Push cap onto nose of set screw and weld. Blending required. Sounds out there, but the floor is so bad, a bird could **** in it and it would flow more air. I have put clay in the floor making it even from the high side to the low side and done nothing else and at 400 lift it flowed 196cfm.
