Hey guys got my Dyno the other day and here is the image of the Dyno Sheet. The Ai-Fuel Ratio is completly all over the place im supprised it got 217KW without a Tune on my AFC Neo which i have no idea what to map it.

Mods are:

* Z32 300ZX Single Turbo 45v3 Turbo

* FMIC setup

* Stock AirBox

* Walbro 050 Fuel Pump

* SARD Fuel Pressure Regulator

* APexi AFC Neo

* HKS SSQV BOV Plump Back

* 3'' Cat Back Exhaust Mild Steel

* Gizzmo MS-IBC Electronic 6 Stage Boost Controller

* Low Boost 8.5psi , High Boost 13.4Psi

Whenever my car is running high boost only there is a crazy screaming kinda sound (Dentist Drill Kinda Sound) i've checked everything that my mates think it is like Boost Controller and the BOV Leaking and it's nothing like that so im thinking it might be the actual Turbo? Maybe the waste gate isn't staying closed and its creeping open under full load i've got no idea

hey champ,

looks like your reading is about 20 to 30 rwkw to high.

it was done in shoot 6, this will always read high.

even 200 is optamistic with a vg turbo. the CHRA is exactly the same turbo as an RB20 turbo, the only differences is the exhaust housing really.

i am not putting you down at all but your real power figure is more like 190rkwk. cheers :D

Yeah well im not 100% sure what your saying is right before i put this turbo on the stock R33 S2 turbo was on there and on around 10psi it made 206rwkw and now its got the electronic boost controller and different turbo i can feel the power is alot more. I left a 06 WRX STI for dust last night but im taking my car down drags so we'll see how it goes now. i understand where you coming from but , ill get another dyno if someone can recomend one around Penrith , NSW there is complete shit all around here for dynos

dentist drill noise? does it have trouble responding now? like its laggier? had the same noise from a GCG hi flow n it turned out to be a bearing failure, the noise was from the compressor rubbing against the housing. Would probably take your turbo intake off and see if it looks cactus.

really ? well it boosts up nice and fast and comes on hard . Just the noise is really weird and it only comes on around 3500-5000 then goes away its when the thing hits full boost .. It kind of sounds like it gets faster whining sound . i dont notice anything in performance loss just the noise is making me worry lol anyone else know what this could be . and yeh its only on high boost modes? maybe there is a bleed valve on my solenoid?>

the dentis drill noise

start you car up and stick you head in the engine bay next to the eshaust manifolds and get someone to rev the car slightly and see if you can hear air escaping.

sounds like your exhaust manifold stus are broken and theres a gab in your manifold. i had this also when i had my 33. on full boost get a screashing noise like the dentis drill. found out 3 broken manifold stud.

also your car is not stock.

stock is stock as in no mods. you put an exhaust in your car that moves you away from the stock ppl

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
