Yeah your right, but as is said, its the higher volume intercoolers and piping that have the stalling issue, because the amount of metered air that is vented is enough to flood the engine (when it tries to supply the fuel to support it), i suppose higher boost levels on smaller coolers would have the same issue.

SAFC's etc can also fix it, as they have a set amount of closed throttle airflow to feed the ecu (which you set).

Just a quick update:

She's alive!!!

She keeps stalling though, which I am very certain is because of running an untuned PFC and having a few air leaks (ie BOV since I don't have the plumb back piping yet) but nevertheless, she runs and blows no smoke :/

Got the tuned booked in for next Thursday. Can't wait!

Yeah the bov would be the cause, they have a tiny hole in them which is enouugh to cause stalling and rough idle, but you issue would be because when the throttle is closed (and the bov is connected to the plenum) vacuum sucks the bov open.

If you'r running low boost, i would just block the bov and let it 'hektic' dose until you get it sorted. As long as you dont have any air leaks between the turbo and AFM, as you dont want it to lean out.

She's all running beautifully now :)

220rwhp @ 10psi which isn't too bad for stock turbo and injectors. Might be able to extract a bit more with high-flow cat and much better muffler.

The only problem I have now is with the idling. For some reason, my car is stalling (or goes to 100RPM before going back to 700RPM) everytime I press in the clutch. Thinking that the AAC valve is the cuplit, I cleaned that up and fixed the issue for a day or so. But now, the problem is reoccuring again. Now, I don't have a problem with cleaning the AAC valve again to fix it until it goes away, but is this a case of dusty pipings causing the AAC valve to get really dirty quickly, or does it sound like I have a vacuum leak somewhere which is causing dirt to come in?

Also, when the AAC starts to play up, my car is doing something really funny. If I drive her cold-ish (water temp gauge just start moving) and I drive casually, she runs really low idle (600RPM). But once she warms up and I start driving it more harder, the idling rev goes up (900RPM).

What the hell is causing this?

...could my stock BOV be leaking?

Ok. This is fking bullshit, but I just found my rear, left window smashed in after leaving it parked outside of my friend's house. Sigh -_-"

If that wasn't bad enough, my dyno sheet was placed in the backseat and what do you know, it was raining. So now my dyno sheet is also ruined.

Oh the joys of owning a nice car... Everyone just seems to get a chuckle from targeting it. Wankers...

So I'm sorry mate, but I won't be able to post up the dyno result.

:P

      Help Understand GTT Boost Setup

      By joshuaho96 · Posted

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.

      Don't do what I did, use a 300000km old housing with billet gears. The old pump probably was clearanced with saw dust, Edward Lee's special engine treatment sauce and a good odo wind back. I had oil pressure issues, then replaces pump with new housing, new billet gears and 2x track day later binned a motor due to other oil related issues due to a previous engine builder. Long story short, buy a M2 or 3 or 4 N55/S55/S58 and enjoy life.

      Yeah. "New pump" does not have to mean "massive pump".

      Well, can you still get an OEM pump, and by the time you're buying a Nismo/N1 etc, just buy another aftermarket pump. It's better to have the pump able to flow more if its needed, than for your pressure to drop off. At any point in time, you're replacing the oil pump in a rebuild. Aftermarket pumps are likely going to be a better economical choice, and they don't have any negatives, even if they can flow more.   Also, when you're saying "replace the pump gears" are you meaning leave a 25+ year old housing in the engine with unknown wear, and just put new gears in? As that sounds silly to me, especially if you do have that minute amount of wear, that means your new pump gears now have a little bit more clearance beside them, which means, whelp, you may not get to build a lot of oil pressure or make a lot of flow.

      Right, but if you replace the pump gears + put a spline or sine drive gear on the crank on a Nismo/OEM/N1/etc pump at that point do you really still want more flow/oil pressure? Let's say this is a the aforementioned "keep it simple" build, no more than ~400 kW at the crank.
