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

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSP male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSP reducing bush?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
