Bridge/Half Bridge?
 

This is going to sound a bit dumb tbh but i was thinking if you have an FD with its Primary / secondary throttles and you do a Half Bridge (just the Secondays bridged) assuming the Primary throttle ajusts the Idle flow why would it still Brap? and if its the case some air flow is finding its way to the secondarys on idle wouldn't that defeat the object of a Half bridge as you might as well have the extra port of the Full if its still going to act the same at low end/Idle?

I only bring this up because there seems to be loads of people Half bridging and using 90mm single throttles? surly that would mean both Ports would get fed on Idle/Low end so the early opening one would dominate the later primary? so shouldn't this mean it would be better timing matched?

Or am i missing the point?

Does that Make sence? Proberly not :)
