The cure for too much boost is a waste gate that releases excess manifold=
pressure. I would imagine any addition that causes an increase in engine=
output would wear out the engine faster - but I'm not sure?!?

The installation I refer to used a single HD8 SU (used on the Austin Heal=

This installation cost $1,500.-$1,600. complete, all done, no extras,
finito, like dinner. Everything else I see out there, cross flow heads,
cams, and other goodies seem to be just the beginning. =

The figure used in this article is 10 hp per lb of thrust and he is

The beauty of this installation is that everything was left stock. The
carbs were unbolted and the supercharger/plenum assembly bolted on with
minor routing of hoses and the like. A single 65" v belt supplies the
motive power for everything.. =
