Intake aerodynamics
Intake aerodynamics
(OP)
Have a dual plane intake which i have some thoughts about the designs of intake how it can maybe be improved, I know a 90 degree /single plane intake would better but not that easy to come by for this engine i was wondering if i fill in epoxy in certain areas to smooth out the entrance to the runners or just file some on the narrow section

Of course, sand cast manifolds typically have a fair amount of geometry errors. So reworking the runner surfaces to balance their flow properties by machining, or adding epoxy and hand working them, should usually improve things.

If the manifold is very well designed with respect to mixture distribution, you can use more boost before the leanest cylinder limits you.
I think significantly changing things should make distribution worse... unless you check mixture flow as you go along. Not easy. Ideally it would require a dyno.
Here "significantly" would mean the changes make a worthwhile difference in total airflow. But if the distribution gets worse you may have to limit boost and end up with less power. If your manifold is very good wrt distribution, IMHO it might be best to just increase the boost if you want more power.

On NA applications that is usually a bad idea for a street engine. Can't say on a blow-thru but I'd be wary.
