Why can 4 cylinder engines run more boost than an 8 cylinder?

Ok, so I'm a car guy and whatnot, but I don't understand much about turbos. Why can we see 4 cylinder engines running 25 lbs of boost, but then a V8 runs for example around 8? That doesn't make sense to me, so I'm hoping someone can explain it to me.

I don't want any smartass biased answers
