Sizing carburetor

On a boosted engine you ate stuffing more air in which expands greatly in the combustion process. You need more exhaust port and valve along with lift and timing to get the exhaust out.
Trust me, I know exactly what’s going on in a boosted engine. I have many. And have built MANY. You don’t “NEED” more port, valve, lift, or timing to make em work. Boost acts like a multiplier of what the NA engine will do. Anything you do to make the NA combo better will make the boosted combo better, just when it’s on boost it’s more better. Yes I said more better.
