Bryan,

I missed where the 43" came from, however from my calculations for 44mm inlet tube, my calculations came to 21.36". That's for a straight tube inlet manifold. That's interesting isn't it.

This is hard for me to visualize as well. Perhaps if you get a chance, you could snap a picture from the top.

Did you get 43 in. from #1 secondary to #2 secondary?

Dennis,

I just looked at your picture again…the secondary look much longer than the primaries. It may be an optical illusion??? I bet you mean 1 1/8 id??

All my tubes are the same length and the same diameters. I can check but I think they were 1 1/4 id. and 1 1/4 od.

Dennis,

Aren’t your primary and secondary tubes different lengths from rotor face to rotor face? If so, what are the two lengths? Are they different diameters?
