Stock Motor, Stock Turbo, Low Boost, Good power :)

[The Mafia]

Well, I got my second tune at a good tuner here in mackay, North QLD (fark its hot)

anyway - Mods (only power listed)

Fully Sheilded Pod Filter

Stainless 3 inch Turbo to AFM to Pod filter Pipe

DNA motorsport Bleedvalve, set at 12psi

Exhaust Cam gear set to 0 Degrees (anything else and it lost power)

Apexi Power FC with HC, and Tuned with HC

Full Exhaust

Hi Flo Cat

Split dump and front all in one pipe (custom made by mate, extended wastegate pipe)

600 x 300 x 75 Hybrid Intercooler

Stocko Intake plenum

No heat sheilding at all

Stock Fuel Pump

Stock Injectors (PFC reads 80% duty cycle on full load)

Dyno Results

Does anyone know how to increase off the mark Torque? And whats with that big dip in the middle of the torque?

I'm looking at a Garrett 30-40 Turbo, with a .63 AR exhaust housing, because I freaken HATE lag. (heheh maybe I should just buy a V8) Will this help me to 250rwkw with a fuel pump and injector upgrade?

Will the unopened motor handle it?

[oRiCLe]

nice dip there right where u want the most torque! dunno, too lean/rich? hehe, doubt it if u got it tuned...heat maybe?

throw a bag of ice on the engine BEFORE u start it make her run cooler hehe...nice power but what boost?

[The Mafia]

12 psi, as I said before

[oRiCLe]

ah there we go, diddnt see it there...

Hi, there are a few things that concern me, that would be answered by a bit more data. Do you have an A/F ratio graph? And a Boost graph? Where is the base ignition timing set at? Checked with a timimg light? This is particularly relevant in light of the zero effect from tuning the exhaust camshaft timing, this is usually a sign of retarded ignition. And that lines up with the lumpy torque curve.

When tuning the exhaust camshaft timing I personally look to hold the max power pretty much as it was, but increase the average power from 4,000 rpm to 7,000 rpm. Usual results are 10 to 15 rwkw increase in average power and around 3 to 5 rwkw in max power. That's what seems to make the car the fastest.

PS; I hope you are not planning on running the standard turbo at 12 psi for long periods of time in Mackay.

Does anyone know how to increase off the mark Torque

$100

NA RB30 bottom end..

hahaha

sorry, that's my answer for everything now..

sorry, that's my answer for everything now..

it's a good answer but it'll cost more than $100...

Sydney Kid, I will try and the the information that you are after this week afternoon. I wouldn't mind seeing what you think.

I forgot to add, I run Toluene, 3l to 30l of fuel. Without it, the car detonates like a bitch.

Oh, and I drive it like a pig, flat everywhere (that is safe to go flat), always on boost, hot or cold day, so yeah. You're scaring me... Could I blow it up? Tuner says its running really good.

Oh, and the powerFC shows the AFM is maxing at about 6000rpm upwards. But one of the tuners (not the last one) said that the map is set properly so that the AFM has no effect anyway.

I'll al;so try and get some pics. I took this one with my phone yesterday, but I'll try and get some of the motor, and the custom mods. (mate is a boily that does Tig and Mig welding like a champ)

I'll also get a pic of his plenum. Its his own creation, and he's put dual throttle bodies on it..

$100

hehehe thought of that, don't you worry...

dude, if your adding stuff to stop it pinging.

there is something dreadfully wrong with the car.

take it and get it tuned properly would be my best suggestion.

Adding stuff is a sure sign something is very much not right.

You'll be surprised how a properly tuned car will go especially with your graph as it looks quite sick and your running a PFC.

Get some more info indeed.

[The Mafia]

I probably should add, that mackay only has 95ron fuel, and its all crap.

No 98 here. Its bullshit

[paulr33]

strange i have a very similar config with 172rwkw series 2 rb25, powerfc same mods etc and im hitting afm max and injector duty at 98.9 % which is much much higher than your 80% very odd

[awurth]

Hey how's it going. I take it Damo tuned it again this time or did the other lad do it. He had my Skyline running with my setup and there wasn't a hint of detonation, that was with 10 degree's base ignition and 15 advanced at 19psi, and that was on Moranbah qaulity Premuim. so I don't know what's up with your pinging. does he know your running the additive? if he's tuned it with the additive and then you fill up and run standard it'll explain it.

Your not wrong about the flat out bit, saw you last week and went to give you a wave and you where past before I could get the hand of the wheel. Good to see your getting some good gains out of the machine. Going to live down brissy way this weekend so cop-ulater.

[paulr33]

if your looking for 250rwkw go for hks gtrs instead of gt3040

the 3040 will be a bit more laggier. the gtrs has been proven many times to handle 260-270rwkw at its peak and its much laggier than stocker turbo, well so the drivers and graphs seem to represent anyway, much less than the 3040 one would assume

[The Mafia]

Hey Wurthy! Good to see you.

Yeah the latest tune was done by Damien, and I let him know that there was a 10% mix of Toluene in, and he said I'll have to run it all the time.

I don't mind, because I can get it for $48 for 20l, and it does a hell of alot better than "octane booster" and works out cheaper.

Paulr33, I don't really want much lag at all, so do you think a Turbo with a .63ar exhaust housing would be good? Something around the 500hp mark? Would I run out of top end serverely with a housing that small?

Someone told me that a .63AR exhaust should be at full boost at around 3000rpm. Can someone verify this?

theres a thread about 6 months old called rb25 dyno graphs or rb25 turbo graphs and it shows various combos of rb25 with various turbo configurations. hiflow and gt-rs showed the least amout of lag and good topend. the gtrs was ballpark around 260rwkw. you should be able to find all the info you need to make an informed decision regarding lag and what size to get

awesome, I will go for a hunt, and have a look at it.

Also i the meantime, I'll grab those figures for Sydney Kid

I can't find it... Are you or anyone able to help me? Would be greatly appreciated.

umm.. all this talk about tolulene... and the fact that you are going to use it constantly..

has anyone informed you of the side effects? to your car that is...

yeah there are alot of myths.... Like it east fuel hoses etc, but I haven't had any problems whatsoever with it, and I have been running it for over 6 months, in 10% Mixes.

And I mentioned that I would post a pic of my shielded POD filter.

Notice the nice stainless steel pipe, right to the turbo? Talk about woosh when coming on boost...
