header tube size

Alan Roehrich · 11-22-2011, 06:50 PM

Step headers offer a small gain, mostly what they do is increase average HP and torque. It is critical that the length of the primary and collector tubes is correct. You can actually get away with as large or larger an error in diameter than you can in length. A two step header (3 diameters) is worth just a few percent in peak power, but can be worth more in average power.

Mark builds the best header I have used. They are a work of art. They fit without having to bust out the hammer. His customer service is second to none.

Keep in mind, there is a common denominator in our cars besides the headers. There is a gentleman in Missouri that seems to know his way around stock eliminator engines. I wish my car was as quick as his.
