All while ago after cleaning my filter my recirc tube came loose without my knowledge, immediately after starting the car. I noticed my BOV had become much louder, my turbo spooled faster (I guess from unfiltered air pulling through the intake recirc hole) and had one more peak 1psi. I noticed my compressor surge problem had gone away also. It didn't stumble at idle, but i ended up putting it back on regardless because I new it woul be be running lean, and I didn't want to chance something getting pulled into the turbo. I then loosened my BOV which was causing the surge. I don't think venting automatically causes every car to run extremely bad.
 
I don't understand why people think because they don't feel something nothing is happening.

Do people with cancer feel it as soon as they get it? No, but they still have an ailment, same with venting. Yes, some cars won't be affected as much as others, but it still isn't running 100% and all for a silly noise. I also love how people get mad when they get called a ricer, yet they do a mod to a car that makes noise but hurts performace. Isn't that the definition of a ricer?

Bottom line hook it up correct, or buy the correct pieces to do it. if yo must here it. You can argue all day long if you want but a car that is vented with the MAF in the stock location isn't running its best.

exactly what i said, just in a nicer manner :thumb:
 
The Deceleration Air Flow Correction cures erratic idle problems for Hot Wire vehicles equipped with an open atmosphere blow off valve. The S-AFC II can also display an incredible amount of data including: Air Flow Capacity (Hotwire and Flap Type only), Engine RPM, Throttle Position, Pressure Sensor voltage, Karmann Frequency, and Air Flow Meter Correction.

Hot wire vehicles?
 
The only reason I'm even interested in this thread is because of that hks venting thing that is being talked about, other than that dont vent, you run like shit between shifts. Go to the track and try to vent. Gaurenteed you wont be able to shift fast enough into the next gear cause the car runs like sh1t. The eclipse has been out for almost 15 years dude, that means there has been 15 years of people trying the same stupid sh1t your asking about and they have tol you not to do it and why but yet you still ask??? Ignorance is bliss I guess WTF
 
Hey guys what's up!! I guess I'll join the party too LOL
But really, if you want to vent, well, all the power to you. After all, it is your car. We all have opinions and experiences with all this jazz, but a fact is a fact. Wether you notice the bad side effects of venting or not, it still damages your engine and your wallet. I don't think you will blow a piston or anything but build ups of carbon will happen over time from unproperlly burn fuel. This with time will also hurt your valves and your spark plugs. Along with many other things. It's exactly like cancer, some people react different from others but it is damaging to the body and could be fatal.
The again, it is your car and you can do whatever you wish with it. :cool:
 
Mine's loud enough recirculated with a K&N filter. If it was any louder I think it would get annoying after a little while. I think the turbo sounds way cooler than the BOV anyway.

As for the risk of sucking things in, you can just plug the hole in the intake pipe. All of the reasons to not vent have already been listed, so do what you want.
 
Try this.

Look at your fuel trims over a week or two vented,then look at them recirculated after a week or two. You will see that venting will cause it to run richer.

Just try it, and no the fuel trims won't change over night, but they will become richer. I bet the low fuel trim will be the worst. I would try it, but I know better than to mess it up.

In fact someone post a log of there car vented for a while, just the fuel trims, then post it a few weeks later with it recirculated.

Vent if you must, just don't say it doesn't effect anything, because the way the system is designed, it clearly effects the way the engine runs.

Main problem I see with venting a BOV is leaking boost pressure and possible vac leak. How bad can running rich on a shift at 6000+ rpm shift be?

Thinking about...wouldn't the extra fuel keep the turbo spooled or respool faster.

Fuel is fuel, air is air, spark is spark, but the proper amount of fuel and air and spark (and compression) releases energy. When the hot gases from this release of energy are pushed out of the cylinder and flow through the turbine, they spool the turbo.

Too much fuel will result in the motor bogging down, which won't help spool the turbo at all.
 
Blah whatever, I don't lift to shift anyways. Might as well get a pipe without a flange for a BOV :sneaky:

I'm not saying go vent your BOV, I'm just saying if your BOV doesn't leak, I bet the difference in a 1/4 timeslip between venting and not venting is nill. :thumb:

These cars are wierd.

Get this...my car runs like crap with the stock airbox, bogs on shifts, put on my apexi intake and the car drives perfect. The stock airbox actually flowed more at idel then the apexi!!! But underboost my evoIII wouldn' creep above 15 psi LOL

Maybe I'll take some nonvented and vented logs and see just how bad it is.
