when on track and wot I get a rather high pitched pschht.. I have the stock bov and my fmic isnt huge but it is free flowing. meh. is pretty much non existent to anyone not in the cabin any other time, basically very quiet on light throttle ie street driving.

forgot to mention that my return piping is red rubber.. red is better!

In regards to what JiVE said:

"And if your after the 'flutter' sound this can also be acheived through the stock bov. Just get a POD and pull the vacum hose out of the BOV. Make sure you block it off real good however, or you will stall."

Have any of you guys actually done that? And what is it about that that would flutter? I've heard of the fluttering before, but i don't know what causes it.

And what sort of effect would this have on driving and safety of my engine and parts?

Sorry to bring up an old thread, but was this ever clarified?

No no no

This will do the complete opposite to whats good

Will open and leak boost when you up it. It will flutter on boost levels where the spring tension is not overcome yes, but you will loose lots of power when it has enough boost to over come the spring

Think about the purpose of the vac line. Provides vac on closed throttle conditions and pressure when boosting to keep the valve closed.

Quick question;

I recently upgraded my inlet pipe(stock rubber) to an aluminum pbm inlet pipe .( for better breathing) . Doing so I had to delete a metal pipe that recirculates air from my bov back to my intake /inlet pipe. Bov is now releasing to atmosphere causing my rpms to crumble and engine almost wants to die off when I rev it. But idle is smooth on its own unless I rev it .i can drive it but when I come to a stop it wants to die off but it will fight on its own to stay on ,it just ruff idles for a bit and goes to steady idle after a sec or two.. By the way my stock bov is pretty loud for being oem as for this topic...

to my understanding this engine was built to reserculate the bov air back to the engine ... . My question is...is there a way to trick my engine/ ecu to running normal as if the bov air was normally recirculating back to my engine or do I have to get a tune to adjust the new setting ?

    • Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.
    • @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.
    • Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.   
    • Holy shit... wow!!! I totally missed this
    • One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
