superchargers

This might be ignorant, but I need to get a definate answer.

It seems to me that with any kind of forced induction there wouldn't be any vacuum from the intake manifold(duh). It seems turbo charging is way too popular for there to be anything super difficult about getting vacuum to all the accessories. My main questions about all that jazz is how exactly do you get vacuum to the brake booster? I sure don't see any hydro boosters for all the turbo kits. And secondly, you would think that having no vacuum would be contraindicated for all the emissions stuff?

How do regular people get any of that shi... stuff to work?

Does nobody know anything about this? Or is it just a stupid question?

Ummmm...there's still vacuum in the intake manifold, forced induction or not. Why wouldn't there be?

[d4h8a1]

Instead of air being pulled into the intake manifold it would be pushed in. You'd get positive pressure instead of vacuum.

There's only positive pressure when you hit boost. When the turbo's not spooling you're not making boost, thus there is vacuum in the intake manifold. Same basic principal with superchargers. At low RPM and partial throttle the pistons are trying to draw more air than the throttle and supercharger will allow in. Vacuum is born. Got it?

What you really need to know is how to keep everything together with 28psi boost, including all the induction plumbing
