Zero Turbo Boost

[John Suter]

Hi Steve,

Not sure what dash buzzer you refer to, but it could
be the heat sensor in the engine compartment. Ensure
neither the super-hot, nor the after-cooled hot air is
funneled near anything combustible. We have
lost/burned-up coaches to this issue when the only
first clue was reduced boost and loss of "zip."
Typically, cracks in the intake side of the cast
manifold was the culprit, but anything that dumps
exhaust into the engine area could be devastating.
