ok .. here the deal .. i got this GST it has a 14b and a type s bov and i think its pretty much stock i think .. dont know much about em yet and not even sure if there is other mods..
the car seems to run good running closed loop
but pulls harder running open atmosphere... can someone explain?

closed loop
pros .. nice and quite swoosh sound .. no one suspects a thing
cons.. seem slower

open atmos
pros.. seems to pulls hard wheels brake traction with ease
cons.. ricer phssssssssst!!!!!!that everyone can hear
idles drop lower between shifts or comming to a stop fixed it by messing with the
biss screw.. now it idles from 950-1600 around there ..
can anyone explain this

 

check for leaks , and your idle does it fluxuate between 950 and 1600 or it it stays steady in between?

 

it idles between 950 and 1600 like sometimes @ 1600 rpm
sometimes @ 1300 sometimes at 950 not really a steady certain spot .. kinda weird

 

when you are open atmosphere the car uses more gas so you will feel more but shouldnt be extreme , of a pull. Yeah the sound will differ when open or closed to atmosphere, daily driving its better to leave it hosed on.

 

i have a 95 gs-t with exhaust and a type s' does same thing as yours.....so i run it closed and then on saturday or fridays when im going to meet sor something i open it.

 

ahhhh ok well at least im not the only one ..
it just seems to run better with out it ... it just has a diffrent idle every time i let off the gas.... is it bad fo the car to run open atmos? .. just cuz the car seems more fun to drive .... it has alot more pull to it

 

its not bad BUT if gas is 2.37 a gallon where you live like here in new york , then i guess you would be upset of paying gas money more often , yea it is a fun having it open atm though.

 

I would imagine stalling your car constantly, (due to stumbling from an incorrect air/fuel mixture), can't be good in the long run. If you absolutely have to have it open, do what 95Ride does, or just run it open all the time at your own risk. Some cars seem to fair better than others.

Personally, I would just say keep it closed. (This topic has been beaten to death numerous times). The performance gain (if any) is going to be minimal and won't be worth the hassle of f'ing up your idle and causing your car to possibly stall. I was like you all when I first got my car and my HKS arrived via UPS. Installed it and tested it recirculated, then was curious and ran it open around my neighborhood just once.....which ended up leading to my car stalling, fouling out a spark plug, and a dead cylinder. I learned real quick not to do that any more. So, pick your poison. I run mine closed.

 

its could kill one of my cylinders? yike ... gonna close loop it tommorow
thanks

 

By dead cylinder you only meant no spark, correct? A fouled spark plug isn't going to kill an engine.
