Early A header options - tuned RPM ranges
Ok, I had to make some assumptions here, as you will see in the input field at the top of the snapshot.
Can you verify my assumptions are correct? also too, pipe diameters are OD based on a .065 wall thickness. So you will have to measure your headers or tubes you will be using for a more accurate calculation.
Also, notice in the 3rd line in the output field, where it gives the approximate rpm range of the header calculated. You can vary the 'Peak HP RPM' field, up or down, if the range does not fit your combo and to find your ideal header.
