4x4le

Ah, dont let them get you down man. Some people seem to understand it and some prople dont. On another forum I made a thread about my experiences tuning with e-85 and everyone became sudden experts and tried telling me a bunch of shit, shit that I knew was wrong and they tried to make me out to be an idiot.
It is easier for a dumb person to seak out a smart person and try to make that person look dumb than it is for the dumb person to try to make themselves look smart.
What these people that are telling you that there is nothing wrong with the stock system and there is something wrong with your motor dont realize is your basicially updating the s13 system to be more like the s14/15 system.
I also cant believe all of these supposed s13 sr owners act oblovious to the well known sr crank case ventelation issues these motors are plagued with. If they havent experienced the ventelation issues first hand they either dont have much of a build, or they are posers that dont give their car a good work out.

Man, dont let them get you down. While they may be making them selves sound smart to other dumb people, who cares if thats who they impress? When its all said and done they are going to be the ones getting laughed at.

You can tell that they dont read the posts either, otherwise they wouldnt say the things that they are saying either. Mark my words, it will happen time after time. No one wants to educate themselves. People are happier thinking what they always thought was correct is actually correct rather than admitt to themselves that they thought wrong.
I have had so many threads turn to nonsense because people were too lazy to read, or too dumb to think for themselves.

Just keep up the good work. Keep the thread open so you can end up with some pics in it showing whats up. If the thread gets locked its going to look like everyone else was right.


Oh, and I too have a freshly fully built sr that I track/drift with the gt2871R .86 and I too get blow by. My engine was built by a very well known engine builder as well.


Im really disappointed at the level of understanding some of these people are at.

Thanks.... Luke (Blu808) is going to get another valve cover and they will see the mods... I need to get my wideband back on cause I upgraded to LM-2, so I might need a slight retune since its pulling in unmetered air.... Will try to keep this updated....

Thanks for your words 4x4le.... its tough sometimes

Oh, are you blow through on your maf? Or is the hose off your valve cover inbetween your maf and filter? If its between your turbo and maf your not going to be getting any unmeasured air.

blu808

yes you will because the computer wont know where the crank case air is coming from.

slider2828

Its not blow through, so its definitely unmetered.... sucks... might be more welding for me now....

It is blow through ken. Combined with the crankcase windage.

I mean I was saying its not a blow through setup.... so I am definitely getting unmetered air in there is what I meant.....

ohh ok. I thought you were saying its not blow by. haha. this shit is getting confusing.

A true oil catch can has Baffles on the inside like these from Toxic Fabrication at Nevrslo Motorsports located in league city, Texas-Houston area!

blu808

Thanks. Those catch cans look really nice. However the issue is not the catch can. It is that oil gets out of the engine and into them in the first place.

instead of welding an AN fitting on the T couldnt u have just capped off one side?
i would also like to see what u have done under the valve cover!
nice work keep it coming!

slider2828

That was the test setup.... We did cap it off when I first test fitted the system. Its just that oil tends to fill there in that small T section and in general I don't trust caps because if by any chance that thing blows off especially during boost, oil sprays everywhere and right on top of the manifold. In that case you are asking for fire under the hood and trust me you don't know until your car is up in flames. So not worth the risk, a safety issue.

Uh... your black air oil separator has baffless.... And in this setup, your valve cover and head become the baffling, which helps keep the oil IN the system not outside the system such as with the catch setup. Also its useless if you aren't set up for a drain back on catch cans....

ok thats wut i thought thanks again

Some Supra guys use the exhaust as the vacuum source. They put a one way valve in between the catch can, and the exhaust piping. That may be another option.

slider2828

Yes I have already thought of that... But you know how much exhaust flow in order create a vacuum.... a lot. also placement is paramount for the exhaust flow to create some vacuum.... Its a lot of work... but yah good thinking though, we are 4 bangers and its hard to have enough exhaust flow to create that vacuumas well, but maybe down the road.

I need to dump on my LM-2 to check my af... Like luke said I might be pulling a lot of unmetered air causing me to lean... Once I verify that, I will update this setup.... Hence the next step....

Hey, I was wondering are you running an aftermarket manifold?

Acually those are my soon to be wifes titties and yeah she is hot.
BTW if it is unmetered air why dont you run it after the mafs? My blitz intake came with a bung on the intake cone itself.

The moroso evacuation tubes for v8's work well as long as they're on a car with straight through exhaust - do research - because despite the pressure in the pipe - the slashcut tubes create a vacuum thats constant between 2in hg and 8 in hg.

Theres a big thread about this on fa and hondatech.

slider2828

I wonder if the direction of the intake bung matters.... I personally think it might because of how it sucking air.... I dunno I have to ask luke and think about it, but I unmetered air IS after the MAFS. I need to run the tube before the MAFS. Well I have an HKS mushroom right now and it has an adapter.... Maybe I can do something about that.....

Yah I have to think more about this, I know its a good source of vacuum but its also a lot more trouble to run it right now.... In the near future I am sure.... I will take a look at it... Thanks great suggestion!

not the current state of my setup, but the manifolds im using

slider2828

Yah that definitely you will need AN fittings.... so close to the manifold that the rubber hoses will for sure collapse cause will be getting really heated.

Took the valve cover.


Then tig welded a -8 fitting on the rear of the valve cover, and a -10 onto the stock location.


Then fitted a -8 fitting on the filter base, and attached the fittings onto the catch can.


Then started to make the lines.


The -10 male fitting in the stock location has a 90 deg -10 push lock fitting attached. Then -10 push lock hose goes from there down to the oem crank case breather tube.


The -8 that is welded onto the top of the valve cover attaches to a -8 90deg fitting that attaches via stainless line to the catch can.


I have also modified the baffling on the inside of the valve cover, and will try and get some pics tomorrow.

Let me know what you guys think.

Why did you put the line before the MAF? Now you are introducing un-metered air into the system.

i think grex kit comes with that on the filter so you recirculate it there instead of the pipe...


yeah i have one opinion luke... why did you have to invent this AAAAAFFFFTERRR i painted my valve cover? HAHAHA i could have sent it to you with the differential as soon as you tell me shipping quote to know how much to send you...

Is it not he opposite? He put it in before the MAFS so the extra air IS metered as it enters the motor.

I put it before the maf so the maf could meter the air that is going into the system.

We tried it a few ways. some with it after the maf, and even though it was a minimal amount of air, it made the car run like shit.

You still have the PCV? If so the PCV is sucking air in through that line on manifold vac. Letting un-metered air into the system.

Def

Most of the blowby will be metered air(over 90%), so the correct way to route it is AFTER the MAF just like the stock setup.

For a quick proof on the mass of meter air vs. total blowby - the only other mass added to the combustion process is fuel, and that'll typically range from about 11-15:1, so less than 10% the total combustion/blowby amount.
