So I got my GReddy S BOV and Adapter from the 1.8T... is my car going to work with it

[OrangeSpeed]

It sounds like everyone who has just slapped a BOV on their car is been having issues. I took the step of gettign the GReddy S and buying the adapter from ATP Performance that with some hose will mount easily. Will I be running into problems though? Im going to put it in anyways just to see what will happen but it sounds like ishould be prepared to stall or something. Thanks

If you rock 6.5 psi then shift to neutral it will probably stall, I can make mine do it and it's been on for about 2.5 weeks but as long as you shift into a gear and let out the clutch to let the PCM catch up, you won't have a problem. I learned to drive around any stall problems after about 10mins, I did notice it runs consistantly richer since it's been on

more boost would probably correct the a/f ratio, I havn't touched the stock boost level. Though I do have a controler to do so

I have a controller too, will running rich mess up my engine in any way? Should i be carefull of anything? I have the boost controller as well just not installed, i got the E-01 so im not sure what to do really. Maybe ill just put it on and hear it and then take it off, just dont want to hurt the car. Thanks

I wouldn't worry about hurting the engine, it will just backfire once and a while, If it would hurt anything it would be the cat's. In that case the check engine light would come on saying there is a cat efficency problem. If that's the case it's covered under warranty so just put original BOV back on and take it to the dealer, just be prepared to wait for the parts cause it's probably on intergalatic back order. I have had no such problems and continue to crack the BOV next to other cars.

As far as the boost controoler goes, I think the breathing of the car needs to be adressed before anyone tries to get performance by just increasing the boost. I want to tweak it to low 14's with stock boost.

Ya I hear ya, im not going to raise the boost that much anyways, just enough to hang with these other cars out here and get some more gettup and go. Im ready for an intake, exhaust and downpipe to get here. Thanks for the info dude. Later

not with the cats on it it wont. Hey i wouldnt say rasing the boost doesnt do anything. I beat a WRX with an Up pipe at 9 psi creeped him pretty good

damn you beat a scooby?

Once again i never said that increasing the boost won't do anything. That's just not where my attention is now

i don't know how the msp is set up, but the bov may cause problems the same way it has been on 1.8t motors. here's why...
(sorry if i am wrong, but this is how i've been led to understand it)

airflow goes like this:
filter---maf---intercooler---bov---motor

but stock goes like this:
                ,------------------, <-- (pipe from dv to before ic)
filter---maf---intercooler---dv---motor

when the ecu reads the ammount of air from the maf, it is going to spit out the ammount of fuel for that much air. when you close throttle and the bov gets rid of that air, its going to run rich because it thinks that air is still there. but with a dv, the air stays in the pipe.
but then again, when you close throttle, there should be no fuel delivery, and it should run on engine compression. therefor there *shouldn't* be a problem.
i've heard talk about moving the maf to a point after the bov to give accurate readings, but i haven't seen any aftermarket mafs that were meant to be in hot, boosted air.

So adding a greddy type S would not be a good idea on this setup?

like you, i wish i had a difinitive answer. i was just posting what i've read. maybe someone can clarify?
