and i currently have one on my RB25 with stock ecu and AFM and on both HARD and SOFT settings it works fine. never has my car idled funny or stalled. When on the SOFT setting, exhaust pops and farts a bit much though. very reliable BOV though :laugh:

holy shit, did you do a search?

This topic is covered about 10 times day.

But To sum it up - You have an AFM. Put an Atmospheric BOV on there to try and sound cool and you won't because your car is stalling all the time.

Yeah this guy up here has the factory BOV and a Blitz bov at the same time, and stalls all the time and runs heaps rich, nice pops on gear changes :whistling:. He just wont believe me when i tell him get rid of the atmo bov. But the best part is, he reckons it gives him like 15rwkw having 2 bovs hahaha.

BTW sorry for the hijack

peace

a few vs about 5,000,000 that have problems

its pretty straight forward what happens. Your car runs like crap because a atmo BOV is not suited for cars that run a AFM.

Oh, and yeah, my comment about searching still stands, because there is 11 millions threads about this. They even have replies from people that claim to have it working properly!

yep, aftermarket management will let you run a vent to atmo bov...

stock ecu fuels for re-circ air from stock bov, when no air due to venting to atmo you get that shiz fart/pop from overfueling ie mega rich fuel into hot front + cat = pop, no cat = flames out of exhuast

according to what I have READ !!! ps my nfo is not 100% as i have not done it, i like re-circ due to coppers having an issue with compressed air release coming from something on 4 wheels or its too loud, which ever they choose to use. yes... both are absolute bullshit but meh.... game on

Nope - I'm running a Powerfc and it still does it.

Its not the ECU - Its the AFM that causes the problem.

It measures the air, the ECU puts in fuel to match, and then the BOV leaks it on idle. (because since the Plenum is on vacuum on idle, its enough to pull the BOV open a little bit) and yeah, air leak.

Hence the rough running.

Hey guys just thought I'd add my experience. . . '95 R33, had a Turbosmart vee port on it when I got the car, ran very rich & sluggish on gear changes, stalled on hill starts, rolling up to red lights etc. . . changed for a stock BOV and have not stalled it since ~ 4 months ago.

On the turbosmart website you can find instructions for PROPER adjustment of the BOV, which will help a bit.

Anyone wanna buy a Vee port? :)

Cheers

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok so will run the piping over that radiator and no plenum it is. Put that money towards a Haltech and see what suits. Any ideas something like an elite 2000 or 2500 right? My long term goal is 300kw e85 and manual swap and that’s a dream come true. For now will be 200kw and auto the stock rb25det neo intake isn’t too expensive with throttle body. If I was to have the port matching done, Would that be better than the stock de intake as the det has bigger holes plus has the spots for sensors etc? And suit more long term?  appreciate the advice?

      You understand AFR is not the only thing that contributes to it pinging yeah? Funnily, what the AFR gauge will tell you when it likely is pinging, is going to make you think things are really safe and good.

      Run the piping how we all have for decades. Also the duel runners with the +T setup dramatically helps it gets on boost quicker. Yes, chase huge power it'll become a problem, but you're a long way off when you're already saying an aftermarket ECU is out of the budget. You also say NisTune as it's simple, and then immediately say it'll be painful, meaning... It won't be simple. It will likely cost you a lot more stuffing around with a Nistune, than just putting a Haltech or similar in.

      I’ll order an afr gauge to keep an eye on it.  Then will get a haltech soon

      TD05 or maybe pulsar PSR2867r Gen 2?  id love a garret but it’s quite out the budget for now and I’m not chasing crazy power.    yeh fuel pump haven’t looked into but whatever works, kind of last on my list.    Nistune because it’s simple but Ik it’s a lot of pain especially as I’m auto +t with the whole seperate TCM etc still investigating that. Haltech id love but once budget tight for now atleast.    finally the reason I’m trying for a plenum instead of the stock intake is I already have a standard Intercooler mounted etc. so the ports are on both sides so trying to not have to go over the clutch fan radiator etc. trying to find a good deal return flow if I don’t than this will do for now I guess. btw any ideas with that, apparently some people have to cut blades to reduce it from hitting the Intercooler piping over the radiator ? Thanks
