Fix for the short intake problem.

[Chezedik]

I have read on here of a few people having issues with fueling because they have their MAF too close to the turbo. I have heard that a sharp bend or long tube is the fix to the problem, but are there others? What about that piece of **** 'Tornado' can it be utilized in any way to counter the vortex created by turbine wheel?

Does anyone else have any other ideas?

lol....waits for someone to try it..... Afterwards they do this....1.Call tow truck2.Get home3.Get online4.Log into Nico5.Go to ka-t forums6.Click new thread7.Post about how the turbo sucked in the tornado and blew up his/her engine

[wild_maxx]

hahaha sounds like one of your stories there Florida

I was recently wondering about this topic as well.. I see alot of short intake pipes with the MAF pretty close to the turbo.... you would think it would cause some problems with the MAF readings...

[Chezedik]

Well, I know I have read about this more than once. Also, Florida, thank you for the help :ROFLMAO

[Jookmasta]

the only way to rectify the problem i think is for us to super-enlarge the hole where the hotpipe runs through and then run the filter down there. never seen this done but i guess it could work. you would have to relocate the fuse box though if s13, not sure about s14............

^That's what i did on my 95. My filter and MAFS are in the fender/bumper void. Worked out pretty easily and no more stalling issues.

[NateDogg]

I just hacked open the sheetmetal and fit a 3" intake and 4" D filter down there with the Z32 mafs. I have a 45* from turbo to a 90* that goes to the fender well.

Greddy has a weird looking restrictor plate in their turbo kits that might help reduce turbulence. It's designed to reduce boost creep though.

[Chezedik]

What is that Nate, does that go in between the MAF to turbo with ears angled back?

I may just have to lengthen my intake.

[1WheelWonder]

Dang Natedog that looks a lil restrictive!

[drEameRvaJ]

I think my car is reading rich because my MAF is too close, but the problem is, there's no room to move it.

Anyone with a idea?

One good way to fix this problem, is get your self a Maf off of a Lexus, Supra, or a Cobra Maf. Pretty much any maf that only reads air coming in one direction. Hooking up a supra maf is also just as easy as hooking up a Z32 maf, and the price range is pretty much the same.

I also remember when I made a post about this everyone laughed at me, but I ended up running a supra maf on my SOHC KAET, and it ran like a charm not one hick up. So there HAHA.

[Chezedik]

On the Lexus and Supra it is not a MAF but a VAF, which is why this works. It would be much easier to do with eManage than with SAFC, though.

[S13FX]

Well it's a setting on the safc something called karnan, or kraman something weird like that. But it worked very well and with out a hic up hehe.

Oh and did I mention very easy to set up .

[Chezedik]

You did, and I remember that. We all thought it would be a lot harder than it was.

Does anyone know the rule of thumb? I have a 45 degree bend and 14 or so inches from the turbo inlet to the outlet of the MAF. I thought I remember 18 inches.

[esahuque]

I was worried about the same thing. I have a JGS manny and i ran my piping the same way JGS does and now i have NO room for my intake, so i have the Z32 MAF right in front the turbo. hope i dont have any problems

[Chezedik]

Does anyone else know of a fix? As of right now, the plan is to cut a hole under the headlight and make a cold air using a Civic intake.

[NateDogg]

If you already have an S-AFC I would sell the Z32 and try a Supra 'unit'.

[S13FX]

What you could do is get a 6in pipe, with a 90* bend in it and position the maf straight towards the ground making a sort of a cold induction system. We did it on my friends car and it works perfectly with the stock maf.

[Chezedik]

I will probably go with the pipe change before I go with the MAF change, but I do have emanage and changing MAFs is as easy as a pull down menu (even if it is a different manufacturer). I am looking at that Civic intake, if I decide not to get it, maybe do that instead. How do you think that the fan affects it when you run the 90?

[S13FX]

Here when I get home Il show you what I did with mine.

I got one of my IC pipes that has a 90* bend in it. Then its bout 4 or 5 inches from the bend, I attached my maf to it, then I bought one of those small type filters for it. Pointed it down on a slight angle, used some zip ties to make it nice and secure.

[Chezedik]

Please do, also, what kind of AFRs do you idle with, does that change with the electric fan (I assume you have one).

[S13FX]

Ok sorry this took a while heh. But here is the Image I promised. Il try to look for a better one, but this pretty much sums it all up heh.

[Edub1]

I see all kinds of people running the MAF with just a short bend. Is it well established that this is a problem? I already have a huge hole where my hot pipe runs down, I'm sure I could relocate the MAF.

One other way would be to weld a sheet metal X in each end of the pipe. This should squash the turbulance but not restrict flow.

[Chezedik]

IDK if it is a common problem, but it is one hell of a problem on mine. I was running 'TOO RICH' on my LM-1 with 270s. I can't put my 555's in until I fix it.

[Edub1]

What are the symptoms of this?

[NateDogg]

Your tune wont have much effect on overall AFR. It will be more rich than desired. Poor mileage, plug fouling, engine stalling, etc..

whats the point of having a 3 inch intake pipe if you're gonna obstruct it?

have you ever let a small piece of soap stay in the shower, only to find that the drain' works much much less well and your shower starts to fill? i'd take that blockage out...

[Chezedik]

GD it Nate, there you are again! And that is exactly my problem. And yes, you are right, I cannot tune it away. So I am hoping I figured it out. BTW, it is weird because pulling the intake off causes the car to die. But it runs reasonably well with it disconnected. Seem reasonable to think that is what this is?

Sounds like the problem I'm having - want's to always run rich no matter what.

[Chezedik]

Well Edub, we are just going to have to give ourselves cold air intakes. Sometimes life's not fair! LOL!
