Hey so-cal mine didn't lose that much boost through the i/c. It's having bov problems and that's what's causing the boost gauge to read 9 lbs. We bumped the boost 2 psi from 12-14 and the boost gauge still read 9 psi just like it did with 12 psi so that's why the bov is being replaced with a nice turboxs recirculating bpv, no more problems, just sweet boost, lol.

PghtC

so when you gonna get rid of that BOV and find out how much it really loses??

I'm not going to give a day for sure because I've got to call Charles tomorrow and make sure the parts came in but let's just say it will be very soon after tomorrow if the parts are in

PghtC

ok...can you pm me? I wont tell :-|

Going to the 9.5 psi pulley was quite an improvemtn. Felt like the difference between turning your ac off during wot x 2. Lots more pull especially after 5K rpm. Massive difference.

I did make two really noticable mods this weekend. One was I capped off the valve cover breather in the back and routed it to a catch can. Butt dyno says weeeee and boost gauge went up 1 psi or so in all RPM which was really impressive. I also gapped out my ik24 denso iridium plugs to .040 and that made a difference in EGT and top end which tells me I was not burning fuel efficiently. And of course the intake. All this combined I would put money on it netted me about 10whp. I cannot wait to hit the dyno. I really feel I will nail 240whp setup like I am now. But we will see... butt dyno lies somtimes when the engine sounds better "my custom intake sounds friggin sweet haha"

Forgot to add, added a turbo xs recirc bypass valve and man.... SOOOO FREAKING COOL!!!!!!!!!!!!!! You can definitly hear it with my intake design.

PghtC

what catch can you using?

And what size plug did you have to get to plug the intake manifold?

I bought a generic version off ebay. I routed both valve cover vents to it and drilled it out to let it breath. Not exactly cali compliant but hey, I am in AZ haha. Also I used a cap out of a kit I bought for plugging vac lines. Was about 1/2 inch vac cap. Stick it on there and put a hose clamp around it.

Forgot to add, my last mod was I plugged the vac line that our bypass valve is plugged into before it went to the vsv solinoid thing. Let it vent open air. Again not exactly compliant with emmisions but my car is not exactly compliant with anything haha. Stopped the annoying boost gauge bounce crap and also seems to have smoothed out mid throttle ALLOT.

I just want to get a catch can, but I just dont know where I am going to mount it. Maybe it will fit on the firewall...??

Only pic I have of the catch can was mid install. It is nice and snug in its location... Just to the left of the radiator cap. It is titanium color. Nice unit actually compared to many I have used on my track cars. Rubber o-ring sealed etc...

PghtC

well that answered that question then... :D

how do I know if it is a quality can or not. eBay is filled with crap.

A catch can is pretty much a catch can. Pretty darn hard to screw up. Pick the shape and size you want and buy it.

PghtC

ok I'll search tomorrow. I notied the seal on the cam cover is starting to look wet. I can't help but think it is because of that hose connecting the cam tower to the intake manifold causing the cam area to be pressurized and causing a leak at the seal.

I need the catch can.

I found it kinda funny myself, most turbo cars do not have a breather from the valve cover to the intake manifold after the throttle body, They usually only have them from the valve cover to before the turbo as not to pressurize the whole damn engine. Glad I made the mod

PghtC

right....there is no way the engine should be pressurized by boost...I guess the engine really wasn't designed for boost.

:D

Hey here is an insane thought....... Tell me what you guys think... could just be that I am tired...

Ok the stock setup basically will pressuring everything under WOT in the engine case the way the breather tube is setup.....

Ok you add 7 - 9.5 psi through the engine case and into the oil pan... with no place for that pressure to go...

Wouldn't that kinda make it hard for the oil to drain back with the drain located lower than the oil level..?

Knowing that, my original thought about the oil not draining properly would hold true , basically filling the sc helping with a seal falure or just a leak..?


Anyways just a thought..............

PghtC

yeah sounds very reasonable. It is a theory I have had for a while...I think that is why I am starting to see seals on the engine beginning to leak....at only 15k miles. 4k miles of s/c and now I have little wet gaskets....which is why I just bid on the catch can.

That is basically the same can I run. I paid lots more because it is a rare color scheme. But overall the same item. Would fit perfectly in the same location!

kytc

Seems reasonable to me. Maybe that's why I haven't had a leak, because my breather tube that goes to the intake has been open since they installed the s/c

PghtC

Just open? No filter or anything? interesting.
