Magnum head porting for the beginner
So...... what’s the story with not touching the floor?
I fiddled with a port on the same head the week before.. any time I waved a 3/8" flowball in the floor, just past the opening, the flow went up. so, it's either too large there, or I slowed the air to the SSR.
So,consequently, when I raised the roof and filled the floor, I picked up an immediate 15 cfm, even though I actually closed down the CSA.
I didn't investigate it any further. The floor in those heads are whacky. There's a 'Rib' running down the length of the floor that traces the Turn wall..(post 16) just didn't have the gas to dissect it.
Getting hungry by then.. :)
