Fast 90mm Intake ports?
It is 1 inch triangle that stick out ¼” into the port?
Also, the TB opening 1 inch into the intake has a lip of 1/8 of an inch all the way around it.
Is there a reason for this or just a mistake in the molding?
Has anyone tried cleaning up the intake ports and the TB opening?
I would think that these areas could reduce flow numbers.
I would like to clean this up if need prior to installing.

Thanks for the picture, now that is a good-looking port.
I disassemble my Fast 90 today and started porting it.
First I remove the obstruction at the outlet of the port just prior to the head and it looks just like the one LSUxBlake picture above.
Also, I notice another large obstruction inside the intake at the beginning of the port that I removed and blended in.
I know that this has to help out the flow number/HP alot!
Anyone else have any picture or recommendations on porting these FAST intakes?

I can't think of any reason for that being there can you?
