100 cfm more with anular and downleg boosters can't beat AFR

No I don't. I agree they take up a lot of space in venturi.
I never thought they were going to put such big boosters in! My understanding was they were going to be something like a truck avenger booster - and in all 4.
So one reason I bought a relatively unmolested 3310-2 is to compare.
Unfortunately while now I have more time, getting time at a track or on a dyno is now more difficult. Such is life.
