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?

    • I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.
    • From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro
    • Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.
    • Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!
    • I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes
