How many CFM is a Stromberg 97?
While Stromberg produced carburetors for a variety of manufacturers, the two-barrels most hot rodders are familiar with first appeared on 85hp Ford Flatheads in ’34 with the model 40; the model 48 was introduced in ’35 (the preceding were both rated at 170 cfm); and from ’36 to early ’38, 97s were installed (155 cfm).
How do I choose the right cfm?
The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width. For example, if your bathroom is 6 feet wide and 9 feet long, its square footage is 54. Therefore, it should have a fan rated for at least 54 CFM.

How do you convert CFM to 2 barrel rating?
To convert this rating to the 2-barrel wet scale, multiply the rating by the square root of 2. 500 CFM multiplied by 1.414 is 707 CFM. To convert this rating to the 2-barrel dry scale, first convert to the 2-barrel wet rating as above, then add 8 percent. 707 CFM multiplied by 1.08 is 764 CFM.
How do you convert two-barrel to four-barreled?
Simply use the square root of 2 (1.414). Thus to convert a two-barrel rating into a four-barrel rating, divide the two-barrel rating by 1.414. To convert the four-barrel rating to a two-barrel rating, multiply the four-barrel rating by 1.414.” You get the idea. Plug your carb into the equation and see the difference.
