Does the shaker even suck air through it or is it just a vent from the outside...because when the car isnt moving how will air ever circulate through it? Does the force of the intake (although not sealed) suck it through?

 

yes the force of the intake sucks it through.... there was a video on youtube (idk if it is there anymore) but they did a test and put a piece of paper up to it and it was deff. sucking in more air!!

 

It sucks in some air yes...not a whole lot like a CAI does.

 

so the suction from the intake is enough to pull air through shaker?

 

yes not ALOT but there is air being sucked by it for sure

 

and wath happern if u have a shaker and u want to instal a turo or supercharger do u need to take off the shaker????

 

yes

 

Some dude at our local cruisin' spot was telling me how his shaker adds 25 HP. I just smiled & nodded.

 

Here's the real deal..

The Shaker system does suck some air in when the car isn't moving, but it must have the factory airbox in place. As in my case with a K&N CAI, I have the ducting connected to the heatshield. Obviously not even close to a being aclosed enclosure, it doesn't suck any air thru the scoop at all.

Here's a video clip from my buddy's 06 Vert showing air being pulled into the scoop (he has the OEM airbox).

There is a turbo kit that will be sold at Galpin Auto Sports that allows you to keep the shaker intact and still use it with the turbo... I forget who the maker is.... it is all new as of Apr...
