Reply to "Annular vs. Down Leg boosters"

tomsealbeachMember

Brooke, THANKS that is exactly the questions I need answered...now if you could just move to sea level and do some testing that would be even better.

What I have read is that the annular boosters are bigger and actually impede the shear volume moving through the venturi, but because of the size, shape and larger booster it creates more velocity at lower to mid rpm's and better atomized the fuel. I recall that the total flow drops by 50 cfm +/- on an annular vs. the straight booster.

My thought was to use a 750dp Quick flow, Pro Form or Demon...actual flow probably 700. I was going to follow Dan Jones recipe of .588 lift and 232 duration on a 10.5-1 CR motor. I'd love to drop $$$ for a fuel injection or webbers but that just not in the budget right now with all the other things I'm doing to it.
