i meant like....4 or 5 psi of boost. i dont think they can make much more than that, not from what ive seen anyway. instead of running a turbo, even if that s 4 or 5 psi, you still need to do all the piping work and oil returns and such. supercharger is just a bolt on item for keeping it low like that. no new manifolds or anything. i have another question thou. how do all of your vaccum accesories work with any kind of boost? like power brakes and all that. i know you could just put them infront of the boost adder but i never see anything like that included in the kits...

Here are some replies I got from a Honda forum I visit when I inquired about effects of boost on vacuum lines. (Yes, I own a Civic too)

"The stock brake booster has a one-way valve in the line so it won't see any boost.

The fuel pressure regulator works fine for boost and continues it's 1:1 pressure rise.

Evap purge is only actuated at certain times which I assume is somewhere in vacuum and low throttle.

The map sensor also can work as long as the voltage output is limited to keep the ecu happy (like in the hack or using a missing link). It's usable to around 11psi. cruise control. i just know that it still works. It's weird when you fall asleep and the bov wakes you up at the top of a hill....i bet."

"The brake booster has a bit of a reservoir for vacuum. Ever notice when you remove the booster line it sucks air in for a few seconds."

"Yeah, it is designed as a saftey feature to give you one.. maybe two good pumps before your brake assits runs out. It is for "emergency" use if the motor dies while driving."

lol well that makes snese i guess. i knew it worked just didnt know why. my friend has a grand national and the intake looks like a regular v6 intake and everything. thats when that popped into my head. hes also running this car at almost 450 horsepower(12.5s 1/4 mile) and all his vaccum accesories still work.
