Also, the higher end Holley based carbs with the upgraded needle/seats can handle 8-9 psi. |
Not true..
Actually you do have a pressure equalization between the two. The vents are common to the inside of the air cleaner which is under atmospheric pressure or a little less depending on rpm, throttle position and the negative pressure within the air cleaner. That all being said, they will equallize due to both bowls venting to a common area. If there wasn't a vent then under the right conditions the bowls wouldn't fill due to being "air locked".
Remember... Atmosphere (@ sea level) is around 14 PSIA, which is still a pressure
