Pod Filter Install, Possible Bov Issues

Hey guys, so I've installed a pod to my r33 s1 and ripped off the snorkel and replaced it with silicone and aluminium piping. Obviously this means that the BOV is no longer plumbed in. When I start it up it is him?

You should really have it plumbed in. It is possible to go without however you can get issues with stalling, backfiring and fouled spark plugs. Not to mention shithouse fuel economy.

Show us a picture?

I dont understans. You started this thread but dont have a problem?

If your car uses standard ECU then your fuel economy will be worse. No 2 ways about it. There is air being metered and then not going into the engine, but the engine still adds fuel expecting that air.

If you have an upgraded ECU then it may have been tuned to iron the issue out

Can you explain that better?

You just said the ecu will add fuel reguard less of whether the afm sees air or not. So you have contradicted your first senstance.

haha

but the engine still adds fuel expecting that air.

This is the part that i don't understand.

You said the ecu still adds the fuel reguardless whether it sees the air or not via the afm. But you also said that it will run rich...

My understanding and real world practices show me it doesn't make ANY difference to fuel consumption whether you're using a bov or not.

The afm will still log air after the throttle is cut, it will be in short bursts, but it will still log it.

you missread what 89CAL wrote.

the AFM measures air which is then vented. The ECU doesn't know its been vented and adds fuel. this causes the problems we were talking about.

it can be tuned for but it won't be perfect. Also many aftermarket ecu's calculate airflow rather than measuring it which eliminates this problem altogether

We'll this is quite the debate. I wonder if it's really him.

First up. Why you buy pod. You need pod or no need pod? I think you pod not need. It is him.

If pod you use then ECU go mental disease it add fuel for counting air but air disappear like magic. It isn't him.

Why not use the air box and metal intake pipe or silicon pipe with bob return fittings. Keep money in your pocket.

What you doing with cam cover gases?

Best post I have seen in a while.

Explains so much. So elegantly.

But still unsure if it is him?

      Mistakes were made, my R34 Story

      I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?

      Anyone running the VQ37VHR with forced induction?

      I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.

      Fuark, at least the motor survived. What brand was the fitting that snapped?

      Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.

      Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
