I’m doing some tuning on my car and hooked up a vacuum gauge and at full throttle I have about 5in of vacuum and at around 5000 rpm the reverse image search email checker port checker vacuum just starts increasing from there. At about 6700 it’s at about 8-9 inches of vacuum.

This is my first carb’d setup so I’ve been reading as much as I can. From what I’ve found, vacuum would be around 1-1.5 or less at WOT? More than that would benefit from a bigger carb?

Setup is
347 10:25.1
Afr 185s
Solid roller 236/243 .603/.588
Chinese funnel web intake, not ported
Quickfuel 750 slayer carb
It is a street/strip version. Has a electric choke, which of course can be removed, mechanical secondaries, and a lot of good features for the price.
