I didn't say centrifugal SC... I just said rarely turbo from the factory.
Roots makes HP down low not TQ so much...
SC = TQ robbing. Roots style is VERY dependable though. However they create MASSIVE heat at high rpms then again most cars don't go to 9k. Power down low is what counts on a typical vehicle. I mean for a truck it's the obvious.... power off the line is critical when pulling a load. When it comes to a typical car the supercharger provides a nice 30-40% increase in hp and does it VERY reliable. It's really only when a car can't make the hp needed to make it competitive in a market that they use a Turbo which will give 50-100+% hp gains. If you have for example a 4.6L ford... do you really need anything more then a Kenne Bell (500-800hp range). Sure a Turbo will make this motor good for 1000 no problem but WHY? No reason. Better to stick to dependable power since it already has displacement.
My Tacoma TRD 3.4 uses a TRD roots style charger to get the job done... and they're famous for not handling ANY extra boost due to the heat.
Still FAR more superchargers of various kinds compared to turbo cars.... Turbo's are getting better and better though, I think we'll see more and more of them around.

previous owner of a Mini cooper.... which was ENDLESS PROBLEMS.... and still slow as shit hence the need for a turbo.
Audi (2 friended owned these and BOTH had the factory turbo's fail)/Volvo/Saab/ reliable???? ehh idk about that, I wouldn't call those dependable honestly.
I'd have to agree on factory equipped total for turbo cars.... you got me there, sitting here I can think of TONS. As for trucks are you talking diesel??? cause of course those are turbo we all know that. Diesel needs massive amounts of boost due to whole different ignition system and engine makeup.

Its all about cylinder pressure, thats the thing you look at when you're talking about the max threshold of an engine.
not boost/whp
s2k internals are extremely strong, ive yet to see an engine fail from making too much power.

^ ... you forgot heat MR. Expert 
I've never SEEN one fail either but... I'd say I've witnessed premature wear from the extra load.... sadly I'm witnessing this personally right now 
(get the expert fired up here)

i didnt forget heat. how do you think cylinder pressure correlates with heat?
and I guess i should have clarified when i made my statement, considering we are talking about a properly tuned engine.
u can go destroy an engine w 3 psi and the smallest turbo ever.

our FI s2000s might be more reliable
(jk, but not really in some cases)
