Running No BOV...please read

I was fed up with the way my car was running rich, backfiring, stalling, sputtering from my BOV, so I took it off and put the original hotpipe back on and plugged the vacuum source. I have to say my car is amazing! :eek: It drives like a normal car. No backfiring, no stalling, doesn't run excessivly rich. It's even quicker than before (probably because the fuel mixture is leaned out a little). Only thing I'm afraid of is compressor surge that is known for hurting the turbo down the line. Does anyone else run no BOV? I almost don't ever want to put it back on because the car runs so damn good! Unfortunatley with the Blitz, your can't recirculate. I guess the point of this post is my car ran like a junker carberated FORD before, now it runs cleaner and better than my stock civic does. I just wish there was a way to keep this drivability without hurting the turbo do to compressor surge.

Post your opinions, and solutions, or tricks you guys have done.

haha, no, its actually an aem sticker because the dudes at the smog shop wanted to see a carb exempt sticker. it is an enjuku hot pipe. i just put the stickers on it so it would pass smog, and it did, in california.

My car didnt have a Bov on it till last weekend and it was putting out over 420 to the wheels... I had it tuned, put a BOV on it and it runs just over 400 now but it's a much smoother accel. Just recirc your BOV, its not going to be very difficult and it wont F@#$ with anything. Or, get a speed density Power FC ^^.

if its just 7psi to be honest, it wont hurt your turbo. Many high power motors have real stiff BOVs that wont even let off until its atleast 6-7psi. That is why you hear alot of the drift cars make a "choooo choo choo cho chc hc ch ch" sound sometimes: BOV hasn't opened.
