If you have a healthy stock engine with modest mileage, strapping on a SC may
be a good option.
My engine was not healthy, so a rebuild was in order anyway. So a cam,
decking, head porting and shaved head were relatively inexpensive as long as I
could do most of the work myself. In fact, it's exactly the engine Moss says
they tested their SC on, so it was not a stock engine.
When I looked into it, I decided (after reading about your car in Kastner)
that the added complexity was not what I wanted to deal with. Upon reading the
Moss blurb, they do not have an MSD ignition system, a vacuum guage or an O2
monitor, so I don't know about detonation with it, particularly since they
tested it out on a 9.5:1 CR engine. Seems to me that you'd need to add some
stuff to the Moss project on top of the $3,500 they want.

Joe----You could do all of the things that are required for a high rpm
race engine, but I don't think it's necessary. An engine in decent
condition will take a modest "boost", such as the one offered by Moss,
with little more than the initial outlay. (This kit could be a bit
overpriced) The power Moss advertises from six lb. of boost also seems
understated. Kastner claimed 165 hp from his turbo kit with the same
amount of boost, and I have good reason to believe this.
The reasons I don't think all of this special work is required stems
mostly from the rpm band where supercharged motors generally make their
high torque and power. This is at a much lower speed, and so the threat
of broken cranks and rods is remote. Flywheels stay put, and threat of
overheating is about the same as a stock motor. Needless to say that
they could, or should, idle well, and deliver fair mpg, if that is a
concern.
Aside from the fact that forced induction engines can also be made to
run cleaner, we can also take a look at what the new car industry is
doing to hop up their sporty models. Turbos and Superchargers,
everywhere you look!
