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?

    • There's a post from a member (can't recall who), went down the path of a twin scroll G30-660 and it's doing over 300kW+ AND comes on about the same as a high flow RB25DET turbo. Have your cake and eat it too in this case. TBH, if I had a 2nd chance of building my car again (i.e. someone gave me what I wanted for my shit box, but the deal was I had to re-build another R33 and keep the change) I would just pop in a stock NEO motor (with new seals, rod bearings, ARP studs, head gasket, sump, Nitto pump), get a smaller twin scroll turbo, modify the stock low mount (keep the divider in place), and make a solid 300kW on 98RON and call it a day. 
    • It's all the sound deadening, and extra shit piled into them, plus all the extra (even though it's thinner) material for crumple zones. I can't fathom in modern cars why they need canbus to the headlights, and why the headlights must be vin coded on some cars to the ECU, BCM, and security module! Especially when they claim it's for security, yet, the canbus at the headlights let's thieves steal the car in minutes, so even more cars are being stolen! The Mercedes Sprinter 907 vans. They're a huge van, but a "basic" van. Yet they have that many canbus networks, plus two Lin networks, AND an Ethernet network. Logging a single network alone of 8 byte data frames, and they will generate a 20mb log file in 5 minutes. That's one network, and I can't remember the exact amount, but there's over 10 full CAN2.0B networks in them. I'm not a fan of modern cars, oddly, more and more I hate DBW, and all the bullshittery the cars try and interfere with. But all that bullshittery adds weight, plus crazy regulations on crumple zones, plus, ever picked a modern seat up, half of them have like 4 electric motors in them and will weigh 30+kg each. Then all the motors for things like adjustable steering columns blah blah blah. And did I mention the sound deadening so you can even hear an ambulance right behind you even if you 7.2surround sound is off?
    • Ah ok, yeah it should be flat, I believe the r34 battery tray has these 3 bumps in them they makes it line up and everything is flat, don't see how it would tilt if everything is secured.
    • Agreed it actively wants to kill you which I love driving fast cars slow is my stick
    • Awesome! I was thinking S14 since they are longer. I'll give those a shot. Thanks for the input!
