19 does sound low, be interested to know what your base timing is set at.

Ive been toying with the idea of water injection for a while now.

The dip in his curve is possible the end of VCT.

you have a thread asking for help gapping you plugs so u can run 10psi........................ strap yourself in !

Dunno bout you but 10psi has my GTR running scared :(

mine went to 22psi one night - f**ken thing went spastic. Like heaps of power.

I reckon you'd go all the way to 25psi before they'd start to show signs of airflow running out. Have you looked at a compressor map? Dale_FZ1 might be the one to ask, I'll email him this thread link. Definately something I'm interested in.

300 kw plus is awesome power, mine makes just over 220 kw's and I think it's awesome already... what mods do you have, you running a piggyback ecu or full fc?

The Mafia: just wondering whats the dip in the curve at around 110 kph? mine has a similar dip and i was wondering if you knew what the cause was

it has something to do with Cams and VCT. Even with VCT off, it can still be there. Strange, but common with RB25's.

hmmm thought it might be that, mine has the VCT always off yet the dip remains..

As above, something to do with cam profiles I think.

300 kw plus is awesome power, mine makes just over 220 kw's and I think it's awesome already... what mods do you have, you running a piggyback ecu or full fc?

PowerFC

FMIC

Full Exhaust

555cc Injectors

WM Injection

Q45 AFM

Datalogit

Wideband

etc

interesting, what ECU are you using??

Not all of the Graphs I have here have this dip but now I look at them a few seem too.

Apexi Powerfc. I've had it smooth before.

like this older one:

actually, there is a slight dip in torque there?

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
