1) The MAF getting dirty from blow-by only applies if you place the MAF after the compressor and will see boost.

2) You'll notice a huge improvement in drivability by going to a recirculating setup, you can tune around dumping to atmosphere (especially if you have a MAP sensor).
obike, not trying to flame, but i've seeen a lot of your posts in this thread that aren't totally accurate. so i'm just going to step in this time.

1) the MAF can get fouled up if its placed after the PCV hose, ie. between the PCV hose and the throttle body.

it can even get fouled up if its too close to either an oiled filter medium or the PCV hose, even if upflow of the actual bung.

2) no one with a tc is going to have a map sensor, so thats a pretty useless statement.

obviously, measuring air pressure inside the manifold is more accurate than metering in the intake tract because its closer to the actual combustion chambers.... but thats neither here nor there.

the point is, recirculating your BOV is the best and most efficient design. And no, it would have no effect if you hook up your recirculated hose BEFORE the MAF and add that air to pre-metered air. It is effectively boosting the intake charge before it even reaches the compressor, which is helpful to have the air measured so as not to totally confuse your ecu.
I'm with nebster, you are a troll. Let's break it down to you.

1) If you read anything I've said, that's what I was talking about. You've just re-typed what I have stated several times in this thread. If you are curious, I can even copy/paste these in a quote for you to understand. Some people have placed the MAF on the charge piping after the BOV in order to have the car run properly in-between shifts when dumping to atmosphere. If you circulate the blow-by gasses (PCV system) into the intake (as it should be rather than slapping a filter onto the PCV) you will either foul the MAF or have to clean it quite frequently.

2) You obviously have no experience with boosted tC's. Several piggyback solutions allow the purchase of a MAP sensor to aid in tuning, and almost all that use a full standalone use a MAP sensor as well. In fact, you can even delete the MAF and setup the car to run purely on the MAP sensor (this would disable the ability to measure intake air temperatures though, so it is useful to have it around just for that purpose). Having the MAF voltage output based on what pressure is seen after the throttlebody is the most ideal way to tune the vehicle when running a piggyback.

Also, let's clarify on some mistakes you have made. If you circulate the BOV/BPV/DV to right before the MAF (meaning that the air will be re-measured before reaching the turbo) the ECU will measure things improperly. If you recirculate, it must go post-MAF.

Just look at any Audi, Porsche, VW, Bentley, Bugatti, Seat, Skoda, Toyota, Mitsubishi, Nissan, Scion, Lexus, Infiniti, Subaru, etc etc etc that recirculates the BOV/BPV/DV and uses a MAF-based system. You'll see what I'm pointing out is accurate.

stop projecting hypocrite. i never said using a lighter flywheel won't improve throttle response and acceleration. you just can't get over that fact to see the real issue at hand can you???
i think SepaTC is trying to say that a lighter flywheel does get rid of throttle delay, but it doesn't do it directly. kind of like how everyone thinks sugar causes tooth cavities. But in reality, it's the fact that the bacteria in your mouth is being nourished by the sugar allowing it to grow and ferment acids in your mouth, which in turns decalcifies your tooth, weakening the protective enamel making it easier for the bacteria to invade the inside of the tooth. see the analogy?


ok, going back to my b18c1 OBD2a to OBD2b wiring matching madness.

wow, someone has a fragile ego! :D LOL... you're the one who has had to post 8 different times to say the exact same thing over and over again. All i did was cleanup some of your mistakes, inconsistencies and contradictions.


FYI, the STOCK intake system dumps the PCV into the intake tract and there is no danger of fouling or having to clean the MAF because it is so much futher downflow....but i'm sure thats what you MEANT to say. :D

dude, i'm knock going to judge, but all i know, is that just because you work for a company or on a racing team, doesn't mean you know everything...... and even if u do, you're not great at communicating it via posts. Your right, i have been doing a lot of clarifying of your posts, in addition to correcting and supplementing. You're not an auto-God..... get used to it.

actually no, thats not what i'm saying at all. a lighter flywheel will improve the rate at which your rpms go from idle to the given input, say 3500rpms.

a lighter flywheel has nothing to do with shortening the time between the point when you touch the pedal, and the point where the rpms start to climb. Why? Because there is no mechanical link between the pedal and the flywheel. The response time between driver input and throttle response is the same no matter what flywheel u use.

It just FEELS better with a lighter flywheel because A) it takes less energy to rotate the fly (which means the same input will give you greater response) and B) once you've escaped the inertia of idling, the rpms climb much quicker and feel more crip than before.

Replacing a MECHANICAL part will NEVER have any effect on an electrical system. :D

To clarify tekstyle..

We will say for the sake of of the conversation that there is a noticeable lag in the throttle caused by an electrical lag. I wont get into arguing that one way or another. I have already posted why a buffer needs to be there and there are varying opinions on how large that delay really is. So we will skip opinions on that part.

So if it is there, your mind is both percieving that as well as the slowness of revs to increase introduced by a heavy flywheel. Take one of those away, and much of what you perceive is gone, which is exactly what those running lightweight flywheels have said they have experienced. If whatever remaining delay is negligible at that point, then you are much happier, the car responds better and the sun is shining

Okay, so let's look at the area you bolded. Wow. That proves your point if you just read that sentence. BUT WAIT! There's stuff before that sentence! Let me re-post that with the previous sentence bolded as well.

Some people have placed the MAF on the charge piping after the BOV in order to have the car run properly in-between shifts when dumping to atmosphere. If you circulate the blow-by gasses (PCV system) into the intake (as it should be rather than slapping a filter onto the PCV) you will either foul the MAF or have to clean it quite frequently.

It's also in the same paragraph, and in English I'm pretty sure that each paragraph pertains to the same idea. Which in this case is the fact that recirculating the PCV before the MAF is what fouls it out. Before you beat me to it, here's a quote from Wikipedia on paragraphs.

Nice try on the attempt to nitpick my posts. What follows is the diagram I posted earlier in this thread about how it should be setup. This also demonstrates where I said the PCV needed to be post-MAF (aka down stream of the MAF).

Put it after the MAF, you don't want metered air to be re-metered.

It should be as follows: Filter ->MAF->PCV hookup->BOV/BPV/DV recirc->compressor
Cliff Notes: Reading comprehension is greater than you.

I actually reported about 8 of your "troll" and other flaming posts from the last few days.......

funny, if I'm "so bad".....why am i still here?? hmmmm??? maybe its because the only people who don't like me are the ones with fragile ego's whom i corrected or showed up in a thread.

get a life dude..... or if u want to get banned, just keep on doing what you've been.

dude do you read have the stuff you post? you flame people way more than anyone does and attack people if they disagree with anything you say. you start wars with people on EVERY THREAD YOU POST

looking at http://en.wikipedia.org/wiki/Internet_troll thats pretty much exactly what you are.

Oh... we have to result to comparing GPA's now? My bachelors was completed with a 4.0, my masters with a 3.96. No one paid for my school except the few grants I got, the academic scholarships I EARNED and the 2 - 3 jobs I carried through the whole thing. My mommy and daddy couldnt afford to pay for my college, so I dont know who you think you are talking about there either. Is that supposed to mean a thing on here? No. So what next, we want to compare whos daddy is taller, or whose makes more money? Education credentials are all well and good, but are not a measure of what you really know.

I have yet to see you "pwm" anyone, ever, on any forum you take time to troll on. If you want people to think you are smart (which seems to REALLY be important to you), why not act like an adult and stop with the childish nonsense and ego tripping?

reported no one to admin, or it was ignored nebster. He supposedly has reported me before, yet no warnings on it EVER . The mods know all about him I am sure... dont worry about that
