You must be concerned that your carb is too big to give adequate low speed torque because that it the main reason for doing this .

It’s also been found that in terms of maximum power that the fuel used along with the air temp that the use of these type of boosters can be a double edge sward .

In some racing situations the greater atomized mass of fuel ( fuel cloud / plume) was cutting into the level of air the motor could bring in which was cutting into the peak power being made on NASCAR track motors.

Basically if your carb is not too big then with these types of boosters the hotter the incoming air charge the less you need the fine atomization these boosters produce.

Nah ... it's a quick fuel bd-850, more or less a jazzed-up 4781 on a 505, OF 1.0 cam, rpm intake, 87 cc old style e heads. With a 3.54 gear and an ultra wide muncie, it runs great.

I ask because I am bored and like to dork around with stuff ... just thought it would be fun to find a core on craigslist, convert it to annular, and see how it compares.
