I do a lot of them with a basic downleg booster 750 double pumper. Tom is spot on with the peak power comment - we see about 10HP more with the bigger carb, but teh smaller stuff is better from a driving and transient perspective. I have not run the 830 annular, but it should be very good, and will give one a try soon.

Cheap vacuum secondary 750 carbs with straight leg boosters are down at least 20HP compared to the good ones...
