Speedmaster intake porting. Hopefully I can make something out of this

Well I did some glow testing today and let’s just say I’m disappointed. Lots of work for little gain

———stock SM————ported SM
.100——-83——————91
.200——-143—————148
.300——-183—————193
.400——201—————-215
.500——212—————-227
.600——221—————-235
.700——225—————-238

now just to try something I flipped it end for end and flowed another port. Both ports were within a few cfm of each other. I mainly wanted to see how both the upper and lower plenum flowed.
