VW 2.0s were putting out 80 hp in the 1970s.

1975 Fiat 1.8L = 95hp.
Anyway... here's my take with the bolt on SC kits.
Computer controlled cars can have the ECU tweaked, flashed, etc, to accommodate a low level of boost. This is done by altering the timing and by holding the injectors open longer. When you start going with moderate to high levels of boost, you can have potential problems, including reduced engine life - regardless of what the ricer companies want you to believe.
1) An injector can only deliver at it's design limit. More boost needs more fuel, therefore, you will need higher flow injectors for big boost. If you go with big boost and do not compensate with fuel, then you are running lean - and HOT. Lean conditions cause CHT & EGT to skyrocket.
B) Boost = horsepower. Your engine was engineered to handle a determined amount of horsepower. How much can you boost before warping a rod? Before snapping a trans mount? Before twisting an axle?
#) A head gasket is designed to seal a certain amount of cylinder pressure. Big boost requires mods to the mounting surface to increase clamping force.
Maybe you didn't mean
that much boost.....
