Annular vs downleg boosters on carb

What application?

I have never used annular boosters on any carb...street or oval track. Gas or methanol.

Everytime I have asked the reply has been the same...downleg.

YMMV.

418 12.5 compression. Decent eddie heads. Middle of the road flat tappet(260@50) suitable gear and 8 inch vert
Car will live between 5000 and 6600-6800 on the track.
Maybe an honest 530-540 ish horse
