lookforjoe Posted October 28, 2010 Author Report Share Posted October 28, 2010 You made it fit. Nice. Let us know how is ventilation going . Also my can works spotless And I see that you figure that catch can is actually baffled ? I didn't know that Yeah, when I drilled the second 3/4" NPT port, I could look inside & see that the existing side port goes back into the can past the vent tube, and the vent tube passes into a baffled section as I pictured it. Can't see inside the baffle area, so I don't know exactly what the baffling consists of. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted October 29, 2010 Author Report Share Posted October 29, 2010 Logs from today - loaded the 1.5kg/cm2 maps & did a quick 21psi highway pull on the way home coming onto 287 too lean @ wot, but no oil loss from the new breather setup . looked in the mirror & saw an SUV with a light bar on the roof someways back, so I backed off pronto & moved into the slow lane. Another log back down to 18psi, much better feel, & timing shows it. Had raised the WOT sliders for this map, too I'll try going up to 19-20psi & see if the timing stays OK, otherwise I'm just gonna fine tune around the 1.3Kg/cm2 map & be done with it.

Captain Bondo Posted October 30, 2010 Report Share Posted October 30, 2010 So works how you want now? I dunno man the setup just seems so awkward and complex to me... one can with BIG filters, and a good baffle should do the job in a much simpler fashion. I am rough-tuning the new EMS this weekend and will start building my breather system this week - I'll make a thread maybe it will give you some more ideas.

Yes, it works, no measurable cc pressure & no oil spray, and only cost $40. That one you had linked was $$$! I don't see it being complex - it just has two inlet vents, drainback & relief vent? Maciek didn't bother including the stock breather to his, his just vents to atmosphere. Maybe I'm being fussy, but I don't want any oil vapor building up in my bay or under the car. I also don't have clearance to add a breather filter on top of the can, it already pushes into the hood insulation. Are you looking at the 1 3/8" ID inlet filters? I also don't see any reason to remove the stock box, and there's no room for a bigger/taller can in my bay... I would love to see your setup as you develop it - will it be on here or TB?

Volvo5.0 Posted October 31, 2010 Report Share Posted October 31, 2010 building my breather system this week - I'll make a thread maybe it will give you some more ideas. Anxiously waiting for this thread. I'm in the process of building an engine and am exploring options for the breather. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 2, 2010 Author Report Share Posted November 2, 2010 Enriched the high-mid load 4200-up, and raised the WOT sliders. Still kinda lean in 1,2,3 - but timing looks good & EGT's are fine. I'll raise the WOT sliders another notch & see how it looks. Run from this morning, steep uphill grade Still haven't done a level-ground hard launch, and since I have the 18"s back on, I probably won't But... I'd like to see what my 0-60 times could be... I also need to do a good 60-100 pull to see how many secs that takes. Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted November 30, 2010 Author Report Share Posted November 30, 2010 Seeing CaptainBondo's breather setup pushed me to finish up mine - basically I just added a much larger vent to the end of the line - I'm still using a catchcan after the breather to drain the remaining condensate. With the breather system as is, I have no oil loss even at 21psi, after 1K miles I've had to drain about 1/4 cup of condensate. I still have a vac draw on the stock breather box vent line before it enters the breather can. Catch can with 1.375 OD outlet (cut from a 740 T/stat housing) filter in place mounted down on left side fender skirt, between subframe & trans drain can be reached easily behind wheel Bay....

lookforjoe Posted December 14, 2010 Author Report Share Posted December 14, 2010 Went back to 22psi for a couple of pulls - didn't have the duty cycle set precisely, so the boost isn't rock steady in the logs. Still easing into WOT in 3rd, so times aren't great. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted December 16, 2010 Author Report Share Posted December 16, 2010 In the sustained 22psi WOT run the other day, I had oil venting with the vapor again I have to assume either the main chamber I have is too small for the two vent sources, and the oil doesn't have time to separate, or the vent tube through the baffle chamber is too small. Either way, I decided to make a single larger baffled box. Since I can't weld aluminum, I made mine from copper It's about 210cu.inches (6X5X7"), compared to maybe 105 (3.14x4x8.5") on the cylinder. I'll probably paint it once I've determined it actually does the job. Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted December 16, 2010 Author Report Share Posted December 16, 2010 Great work Hussein, starting to look like a never ending story! Yeah. I'm just not a mechanical engineer, so I just have to experiment until I find what works What sort of breather system do you have in place, and what rpm/boost levels? What's odd is that it really seems to have started once I crossed 21psi/6500+rpm on the 20g - so it would appear it's not purely boost, but the volume/cfm's that the larger turbo's generate that also impacts the rise in cc pressure? Anyway, I'm hoping that the larger volume can will resolve the oil escaping issue - at least the CC pressure issue & turbo leaking issues are resolved!

lookforjoe Posted December 20, 2010 Author Report Share Posted December 20, 2010 So far, the new can seems to have resolved all my issues. I've run over 22psi boost at sustained >6500rpm & no oil accumulation in the tertiary can. I have to thank Captain Bondo for sharing his can design - it really hadn't occurred to me to make one myself! Considering that there is zero pressure, there is no reason to suppose a sweated copper can won't hold up as well as any welded aluminum, and I can't weld aluminum This is the overall layout with this instead of a filter on the can... ...so I can still drain the final condensate. If I find that there is NO oil vapor at all, I may put the filter on the secondary can, I just don't want any oil residue in my bay. This is how I baffled mine - following the design of the stock can - vapors enter in the upper inner chamber & have to drop down & around, separating from the oil, and exiting through the outer/upper chamber I tilted the base so that it will run off to the drain as the lowest point I soldered a tab to the back that attaches to the main fuse box. That is enough to secure the can & maintain a nice drain height back to the block Now I have to redo the airbox, since the breather lines are now in the way of the casing.

--Aaron-- Posted December 20, 2010 Report Share Posted December 20, 2010 Neat stuff! Pretty soon you'll be out of room to mount nifty gadgets in that engine bay! Best of luck. Quote Link to comment Share on other sites More sharing options...
Q-Ship Posted December 20, 2010 Report Share Posted December 20, 2010 It must be said: your drawings are really clear & I'm learning a lot. Thanks for letting us ride along - humbling to think you're running essentially 2x the boost I am right now :blink: Quote Link to comment Share on other sites More sharing options...
