maciekb2002 Posted December 22, 2010 Report Share Posted December 22, 2010 I personally think that is to cold to work outside . Plus that tank is almost as big as dry sump. You should convert that BTW Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted December 22, 2010 Author Report Share Posted December 22, 2010 I personally think that is to cold to work outside . Plus that tank is almost as big as dry sump. You should convert that BTW Yeah, it really is, too cold and big tank!. Finally no oil loss through the breather! The can l had like yours obviously doesn't work with two inlets, it can't handle the volume. Now, I just have to refine the tune for the higher boost & colder air! No dry sump, that just looks like a royal pita. Custom intake, maybe! Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted December 24, 2010 Author Report Share Posted December 24, 2010 Made my alternate can today with integrated filter. Its about 2/3 the size of the other one, approx 144cu in. I can't fit my airbox with the tertiary can vent routing, so I figured why not try this. I no longer have any oil buildup in the can, so I'm hoping I don't get any oil residue out the filter. The other was Copper, this one is 18gauge Brass Inlets go from 1/2" ID to 3/4" ID as they enter the can. Drain outlet is 3/4 -1/2", lays on the lowest most point of the can. Filter vent collar is 1 1/4" ID was thinking of the Lambda symbol when I did this one.. end plate inside end plate outer soldered tongue to make a support bracket to the inner fender.

lookforjoe Posted December 25, 2010 Author Report Share Posted December 25, 2010 Ran this can yesterday. After 4-5 7k 22psi runs, I had oil coming out the vent filter. So, 144cu in is too small for the pressure to relieve & the oil to separate from the vapor. I squared off the bottom of the can last night, so now it's up to 180 cu in. volume (5x6x6"). I'll try it tomorrow & see how that goes. Fortunately I have another can of Gunk engine degreaser Hopefully that will do the trick. I'd prefer to use the filtered can, then I can eliminate the tertiary can in the fender well & refit my airbox. Next step would be to add a filter to the larger can (210 cu in) that I'm using now, that one does not pass any oil out the vents at all.

lookforjoe Posted January 4, 2011 Author Report Share Posted January 4, 2011 Running 22psi again now that breather system is good. Using the larger can, haven't retried the filtered can yet (redid the internal baffles to match larger can, greater volume on inlet side). Still refining the apexi duty cycle - have an initial spike to resolve with the feedback cycle setting. Had developed a miss under heavy load this past week - had to clean the cap & rotor, & replace the plugs. This time I put R5672-a8's @ .030" - I removed BKR7E's @ .034" AFR's are pretty stable - if a little lean @ WOT (in 4th) Logs under report boost by 2 psi Made playback vid of this log Quote Link to comment Share on other sites More sharing options...
loseR99 Posted January 5, 2011 Report Share Posted January 5, 2011 Hussein, I'm sure you've already considered this, but I thought of something while installing my Snabb intake pipe. I believe the bottleneck in the oem intake tube is designed to create a venturi effect on the ptc sensor, allowing crankcase vapor to be drawn from the oil trap and a rate consistent with the increase in manifold pressure. Would it be ok to assume that the lack of this venturi effect through an inlet tube that maintains a larger diameter would have any effect on the motors ability to draw back crank vapor through the intake as was designed? Just a thought. The effect might be negligible considering the amount of pressure that your system is capable of producing over a stock system. love to hear your thoughts on this. -Adam 1 Quote Link to comment Share on other sites More sharing options...

I made one version with the PTC barely inside the ID of the tube - which might actually improve the venturi effect, actually... .. but I think there is sufficient velocity traveling through the pipe to maintain vacuum on the breather system either way. At idle is the only concern, but as long as you have the vacuum line to the end of the manifold, that is a non-issue. All my issues arose once I switched to vent-to-atmosphere. I actually added the PTC back to the can, on the original vent line - I just drilled out the tip as large as I could without destroying the heater element. I did this to aid in reducing the level of mung that accumulates in the cold weather/short trips. Quote Link to comment Share on other sites More sharing options...
loseR99 Posted January 5, 2011 Report Share Posted January 5, 2011 Maybe its 99+ thing, but my PTC doesn't have two lines entering, only the top which is stepped down from the manifold end port. Maybe at idle it is losing vac because of the two ports? If you'd like I can send you the PTC i'm talking about. Not sure if its something you'd like to experiment with or not. I also have one from my 01' S40 which also has only 1 port on top. Quote Link to comment Share on other sites More sharing options...
JackDeisel Posted January 5, 2011 Report Share Posted January 5, 2011 If you stuff the catch can with steel wool that will reduce the amount of oil that will get out the filter. Quote Link to comment Share on other sites More sharing options...
Falcone Posted January 5, 2011 Report Share Posted January 5, 2011 Hussein, I don't think your problem is you're catch can. I'm running 22psi on a 3582r, and haven't experienced nearly as many problems as you are. I'm tuning with motronic suite and a clone whilliem programmer. My catch can is an empty mini propane canister, with sos pads in it. It never catches any oil, only milky sludge. Its got a drain on the bottom, and is fed by the block vent. No pcv system in my car (yours does iirc, try removing the stock breather box). You seem to have way too much blow by. 1 Quote Link to comment Share on other sites More sharing options...

No pcv system in my car (yours does iirc, try removing the stock breather box). You seem to have way too much blow by. Thanks for the input. Early on I did a leak down test, and the % margin was very low & even across all five (buried somewhere back in the thread) Probably if I had just removed the breather box from the get-go, and vented to atmosphere, I wouldn't have had the issues I've had. The problem was a combination of boost & rpm levels, and inappropriately sized vent lines & fittings. It's all good now, so in my case (with the extra cam cover vent) the size of the can definitely makes a difference, since I get no oil loss, no oil in the vent can using the 210cu in. can pictured. I'm not going to bother with the filtered can, since even if it's good, the condensate will still make a mess of my battery area - I'm too fussy about that :lol: Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted January 23, 2011 Author Report Share Posted January 23, 2011 Started fabricating a ME7 style intake to go with my '03 head. Using TB sheetmetal intake thread for reference. Flange was cut from a ME7 turbo manifold. 6" runners, 2"OD, 1.75" ID, cut on a 5º angle. Plenum backwall is 1/4"; 3"x16". Shooting for plenum size of 1.5x engine displacement (approx. 210CID). Bellmouths are hand-tooled (ball pein hammer) T/Stat neck has to move trying to figure out the plenum cross section, TB needs to be offset down & back somewhat Looks like I'll need to use the '99 PS pump - the integral reservoir just makes #1 plenum end too cramped. I'm going to need to switch to the '99 P/S & Coolant reservoirs. Pump offset is different - so I'll have to cut & modify the '98 mounting plate to move the pump outward about 1/4" to align the pulleys. Pulley is also smaller, so I wonder if the rack is also different valving? top plate will be along these lines.. Quote Link to comment Share on other sites More sharing options...
Chilled man Posted January 23, 2011 Report Share Posted January 23, 2011 If you change to the 99+ PS Pump you will need to also change the lines. The connections are different. Also I would go with the 02+ coolant EST and such that will get your coolant issue solved also. Quote Link to comment Share on other sites More sharing options...

Also I would go with the 02+ coolant EST and such that will get your coolant issue solved also. I have the two main lines (#11 & #15) - just need the suction hose to the reservoir. I'll need to get one of the brackets that goes on the strut tower. Did you notice any difference in the feel of the power steering using the later, smaller pulley pump when you switched over?
