I was looking at flow rates for mufflers, and was curious on what our motor put out CFM wise.
I know that VE and the CFM varies at any given rpm. And our motors pull in around 300cfm, on an average, correct? But does compresion up the CFM or velocity of the exhaust? if so, how much.
and i know cats create back pressure, and i assume that back pressure is directly related to CFM or velocity. SO, lets say this is a catless car. with a single exhaust.
I found that Dynomax Super Turbos flow at 410cfm.
Flowmaster 50 series flow at 362cfm.
those two were tested at 20.3''
and then i found
****** Aero chamerbed which flow at 441cfm
but was tested at 28''
i beieve that the Dynomax S/T is the prefered choice in terms of flow rate.
Again, this is on a Catless car. Single exhaust..
EDIT: also, the mufflers tested were inlet-offset/outlet-center, 2.5''
