I cant figurre it out

Ok ive softened the bov, Ive turned down the boost and I took off the negative battery connector if it was fuel cut. For some reason when I punch it after a little bit it starts cutting out and is slow as heck. It all started happening after I put on my upper I/C piping with the bov. Also the guy who did my timing belt said it wasnt nothing from that doing it. A couple times the I/C piping fell off while I was driving and I ran it like that for like a minute or two without knowing. Could that screw something up?

You more than likely have a boost leak.

Ok but would a boost leak make it feel really slow and then die out when it gets a little higher in psi?

Sure it would. You're leaking metered air which makes it run rich and kills performance.

Ok cool I think I fixed it. But since I put my hard upper I/C pipe on I havent heard it run good till now. So woul the air rushing through that pipe be alot louder then when it was going through the stock rubber one? Cause it seems way louder especially at higher rpms coming from that area.

yes, of course it would be louder, is vibrating off the hard piping, the old rubber ones dampen the noise level., the same goes for hard air intake pipes with recirculated BOVs, they are louder with the hard piping, I cant hear mine due to the ribber stock intake pipe, but my buddy who has a hard intake you cant hear it decently.

Im having some more problems though, with boosting over 10-11 psi I thought it was the old bov causing it but now I got my new one on and I still cant boost past that, any ideas?

 

[andymoraitis]

Di you run a correct boost leak test with an actual leak tester and air compressor or did you move some clamps around and think that it's fixed?

In addition, what type of plugs are you using and what are they gapped at? What kind of boost controller are you using and how is it connected?

 

[DSM-Talon]

Sorry guys I ficed it I was being a ####y and was to scared to turn the boost knob to for so I finnaly manned up and turned it up far enough. Im currently runnning at 14 psi

Ive got a question though about the boost leak test, when you do the tes what needs to be plugged off? Like andymoraatis said, ya I just moved and tightened some clamps and noow it ran like it did but still I want to give it a real check sometime soon. When I did it I tool the complete intake off and took all the vac lines out and let them hang there also the recirc tube for the bov wasnt plugged so do I need to plug those up and if so how? I want to do a real test soon. Oh yeah and its kind of funny also that I just started working on cars and I fixed it before a guy whos been working on volkswagons for thirty years could, goes to show you the diff in a car.

Take some time and read through the VFAQ which you can find here:

I don't test through the turbo and prefer to test at the inlet for the intercooler to see if there's leaks in the intake piping.
