Whoa, whoa, whoa, hang on their snoopy. It’s not that I disagree with you fully. Even what you are “arguing” was my may of thinking in the beginning also. Tis why I spend the time on the inserts in the first place.
But you’re argument becomes futile when you sit and argue logic and I argue dyno tested results doesn’t it?
You’re arguments will hold water when you have bolted an engine on a dyno and tested all the scenarios. Until then, your argument holds as much water as a burlap sack.
The carb inserts ARE NOT velocity stacks.
They are, just not optimized to the fullest extent.
I'm not saying you are wrong that taking the inserts out will give more power, just that you can get even more power if you shape the intake better. Without the inserts it's far from a optimum or close to optimum shape.
If I had a lathe I would make my own velocity stacks.
