Ron,
There physically is not room (internally) to create a 3.0" in and out version. This is because it would require a bypass valve that is 3.5" diameter since we only use actuators that pull 0.675". This 3.5" valve will require space we do not have. With the 9.25" wide shell, 2.5" is about the best we can do and that took some creative engineering. Note how I shifted the outlet to the left slightly?
When this first set (of six pair in work) is finished, we will get them on three dfferent cars (my 340, Dad's 470, and the 428 Cobra-Jet Torino. I will also test them on a Superflow 600 bench to see how restrictive they are in both modes.
Should have sound and flow numbers to share soon I hope.
Tom
