Hi Robert,

Thanks for your question. The 2748 CFM capability really depends on the other details of your vehicle installation: carb size, air filter, etc. Offenhauser never had noted a range for this part when it was created. This air horn was originally manufactured for a Studebaker and the carbs were much smaller (about 400 CFM). Be aware that running anything larger beyond 500 CFM may not work.
