after Guy fitted my BOV on for me (HKS SSQV) my car was getting more km's out of a tank, and it was backfiring when i gave it stick causing the flames... awesome...

is genuine HKS... Sunny dude, i would take out your BOV and just sell it and get a genuine HKS... china BOV's = super ghey

100km's less out of a tank is not worth the wank factor, more km's is though

As Bubba said, it wont run rich unless the BOV is actuating.

If the BOV is actuating under load. Its not tight enough.

Properly working Atmospheric BOV's will only 'smoke' and run 'rich' when they need to "Blow off" extra air. (And that's to do with changes in Load)

Just tighten it, make it work properly.

That 'Extra' fuel coming through the exhaust would have just gotten burnt by an unloaded engine anyway. Which will not effect your economy. Really, its not extra fuel, because it was going to get injected anyway.

(On a side note, AT A GUESS, because the princeples of induction may counter this - if you plumb back a bov in front of the AFM, you will read that portion of air twice, and then there will be 'extra' fuel injected.)

Your smoke on load is a sign the BOV may not be operating correctly.

I think im just repeating what people have said ?

However there are some myth's being said too.

its got nothing to do with the bov spring being tight enough.

its got to do with the stock bov recirculates the air back into the intake pipe. atmosphere bov vents to the air. therefore less air in the intake

less air + same fuel = running rich. its very common problem, atmo venting bov are complete wank factor nothing wrong with stock bov i had no issue running one with 350rwhp and if yours is leaking get a set of gtr bov

Are you saying all atmospheric bov's will reduce fuel economy ?

Retract this, ive realised stock setups dont plumb back infront of the afm:

Now you can hunt down that dude who sold it to you and make him eat it...

The guy was saying that he was getting lots of black smoke UNDER LOAD not on liftoff. Puffs of black smoke on liftoff or gearchange is normal with an atmo bov that hasn't been tuned for it. PLUMES OF BLACK SMOKE UNDER LOAD IS NOT JUST BECAUSE THE BOV IS ATMO. Something is wrong and it is most likely leaking when it shouldn't be.

wank factor?

Whats wrong with atmo bov's? I quite like mine.

As long as they arent overly loud.. they sound nice =)

If you like the sound of Harpo Marx sneezing or the amplified noise of a mouse being squashed, I'm sure they sound real good to you.

These noises are in no way associated with any kind of 'power' experience. If you like repeditive 'pachoo' and squeaking noises then Fisher Price has a great range of electronic musical toys on offer this christmas.

I reckon they should make them sound like farts at least then they have better comedy value.

My kids (incuding the 3yr old) now point at cars and say 'ricer!' when they hear these.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
