How much would I lose?

Nah, you didn't sound like a pompous ***...I had the volume turned down! lol :mrgreen: Just messing with ya! I think you may have mis-interpreted what he meant, tho. I think he was just telling me how to get a little more HP out of the dual plane, not really turn it into a single plane. Basically to try to even the playing field a little more between the two different styles of intake.

No, I got what he was saying :toothy8:. I was just pointing out that the terminology itself was wrong.
Nothing wrong with the modification, particularly if you're running a carb a little on the small side.
