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

Yaaa I had some time in this one and can’t wait to really put it to the test. I’m not a believer in sharp edges. I guess I always keep a picture of airplane wings in my head. Nice and rounded on the leading side thinning down on the rear. Needing volume and access to the air you really can’t use this principle to a tee but I sure like radius’s.


Yep. Sometimes you have to compromise on a shape (yes...it’s all about shape) to get size and taper.

My SD has pretty sharp dividers in it so I could get the taper I wanted. It was a compromise.
