My Intake Pipe Design, Stalling Issue And Lean Popping

[Guilt-Toy]

have you done this test yet?

Where are the pictures of your intake pipe ?

If you want help hurry up, I aint got all day! =)

I tried it but it didn't really do anything as the lean popping is mainly when holding about 2k+rpm on idle. Will it count if I get someone in the car to hold rpm while I fill it? Pics on my phone of the pipe on the car, will upload tonight when I finish work, can't upload pictures from the phone.

In regards to my fuel setup though everything is brand new except lines and regulator. Nismo injectors, Bosch pump, ryco filter..

I think its because of your pringles designed intake pipe you're popping, as we all know with pringles, 'once u pop, u cant stop'! On a lighter note, i know how frustrating ur problem is, hope u find a solution soon, sounds like an air related issue, did u get jez to look it up in the wknd?

The point he is getting at is the fuel being cold, as long as you don't leave it idling for 10 hours after filling it it will answer his question.

Shall send you a pm shortly. Just got home and it decided to lean pop on idle now and constantly too. I might have to give that test another go. But its strange, on hotter days I've given the car harder times and idle is fine...

I attached them to that pm I sent you but after checking it nowi see that didn't happen. Ill post then again here and in the pm. Your help is always appreciated man, sorry about that man.

I tried PMing them again. Realized they are close to 2MB each. Got my computer now so lets do it from here! Pictures are pretty rough, I'll be pulling it all apart tomorrow for better pics of the pipe out of the car.

Also just fitted a new fuel filter, just incase.

Can't edit the above post anymore but here are pictures of the intake pipe OFF the car. You can see the outside and the inside of the pipe. My new design pipe has another bend just at the turbo with a 2 - 3" leg which will be the mounting point for my return and breather lines. It will have 2 maybe 3 bends in it.

The black shit is that silka sikka or what ever its called, that black glue shit. We put it over the weld bead just incase there was an air pocket somewhere.You can also see that the intake pipe is not exactly 3" on the bend. We sliced out a moon piece then bent the pipe shit and welded it up.

Can you get it on a dyno and see why it is running lean? It sounds like it is just a coincidence that this has happened after you changed the intake pipe.

do me a favour, turn the air flow meter, so the sticker is facing upwards to the bonnet. so turn it clockwise.

il have a look at the tune soon.

Hey sarge. Those welds are hectic. Ill subby all my fab work to you from now on. Make sure u save those pringles cans for me lol.

Anthony has a good point. The afm element position is fairly important.

The afm element orientation isn't an issue if the AFM is standard.

[DVS JEZ]

Do u mean in a standard housing or standard for the car its in?

He has a z32
