Booster size

What would be the difference between a 0.140 and 0.160 booster in the same main body 650?

I currently have a 4777 with straight leg 0.140 boosters and an 0-8541 main body with the straight leg 0.160 and can't help but wonder if the smaller diameter booster would better suit a street/strip deal? I would suspect that the smaller diameter would aid it with getting the primary booster to flow sooner.

Has anyone seen a significant difference in booster flow with just a change in the diameter?

I like smaller legs in a straight or DL, the velocity leaving the booster will better suit fuel sheering. .140 is what I would use on a 650

Thanks Mark that's what I thought as well.

Do you know if the emulsion package is different for larger booster diameters as they come form Holley?

Shouldn’t be, but no telling what they are sending out.
