Re: FYI: 5KCSTQ Exhaust system

Ed-
I think Milt is onto something.  Last year I had to replace a perforated
exhaust manifold on my '875KCSTQ.  The exact part was hard to find and too
$$$.  The new 2 piece manifold was also too $$$. I found a good straight
used part that fit right but
the throat was slightly different.  It went on and works fine, but now I
have to carefully feather the throttle because I run to 1.5 boost without
even trying.  The fuel pump shut off at that point makes for a jerky ride.
Of course, I continue to agonize over whether to ground the shutoff circuit
and see how much boost I really have.

PS - Charlie, how's the adjustable cutoff circuit coming?
