Re: FYI: 5KCSTQ Exhaust system
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?
