What Boost Do You Run In The Stagea

[KR.15.YS]

Hi all, just wondering how many of you's out there have wound some boost into your cars?

We run 10 pound all day everyday.

What is everyones idea of a safe boost level to run?

Also what sort of fuel ecconomy do you guys get now?

[Terminal]

... you's ....

Sorry, firstly a pet hate of mine, it's 'you', plural and singular.

And on topic, i run my bleed valve at 10psi as over that the stock stagea computer has a fuel cut and the car jerks around. not a fun experience.

I'm getting about 350 - 370km to a tank city driving and over 450km to a tank country driving

[Mr_RS4]

I've got the jaycar IEBC set at 10 pound on high boost setting. With the stock (well I've got an R34GTT but close enough) intercooler and turbo I won't run any higher than this. I also doubt if I did I'd get much more power anyway. As it is even though my guage only just flickers about the 10 at times I still hit boost cut when I push hard between gear changes (auto).

i'm not having a real fun time with fuel atm as most people here will tell you. If I can get it over 300k's city i'm doing well atm. But I've only just bought it and am now learning how to drive it for better economy (= baby it). on my current tank i'm at 70k's and in between 3/4 and full so its looking better already.

mine is running 11 with the uni chip, seems much better than standard but missing under load, think its the coil packs. getting about 280 to 300kms a tank city driving, but i do have a bit of a heavy foot

[Techo]

It's prob a good idea if you add if you have the standard turbo, exhaust & any other mods.

Mine is stock except for a splitfire filter, & i run around 10, but i find at around 5000rpm it feels like a stutter in the power band & i got no idea what it is?

[CruiseLiner]

0 boost for the last 8 months haha, and before that was 18psi with 350rwhp for about a month, and before that it was stock 7psi with the rb25.

soon to run 17-18psi as a base tune, and then in a few months hoping to put in over 2bar and push the t04z to its limit

[AlexCim]

run 7.

Anything above that i just get cuts/bad economy/waste

I find 7 is a good boost too. I need a tune with a DFA too. Waiting on a daughterboard to be created though

[AMS]

Well currently I'm running 8 - 9psi...

When I get the Jaycar IEBC installed etc. I will be running 10psi low and 14.7 (1 bar) on high.

Fuel economy sucks Cant really get over 350 no matter how hard I try

[Ska]

Once I get it tuned properly I want to run about 10 psi, as the stock rb25 turbo's do not respond well to anything over 1bar for prolonged periods, or so I have been told and read on here, (there are thousands of threads on this subject).

But I was getting about 400kms out of a tank, but that was with the pfc tuned with a blocked radiator at the time, so it was tuned stupidly rich.

I have to clean the back screen at least once ever three to four days otherwise it gets blocked by that unburnt fuel soot

Hopefully in the next couple of weeks it will be tuned properly on 10psi, and I will be aiming for ~500kms out of the tank, hopefully

Hey Ska, what's the radiator/back screen YOU'S (singular) have to clean every week??

Huh? Back screen........? Please explain?

[munchstagea]

back window gets dirty from rich exhaust.

[3intheBack]

Quote SKA -

Q was, what is the back screen? is it just the rear window?

I thought at first it may have been something on the intake causing your fuel rich problems. I suppose I had in my mind what others have said about cleaning their AFM's.

I just wanted to be up to speed with my servicing before it became a problem.

After reading some of these threads it seems that most people have a squeak/rattle or misfire problem somewhere. Everytime I drive mine I listen out for things and have yet to fault anything. (except for the noise in my left ear saying "slow down you've got kids (3) in the back!")

It runs flawlessly and I love it more each time I drive it.

[Ska]

OH OH OH Sorry Rear Screen = Rear Windscreen

And its the whole back door and rear bar, that whole area gets covered in black soot, but I am sure it is because I am running stupidly rich, I leave a HUGE black cloud of fuel smoke when I do launch it

Currently running 10 psi controlled by the IEBC with the DFA tuned (~11 to 1 A/ F ratio) which was as good as we could get it with the standard exhaust. The R34GTT intercooler is fitted but the Magic cat is still in the garage with the 3.25” exhaust. Plus the SITC is fitted, but untuned, it is waiting on the exhaust.

Now that the project R33GTST is serviced, registered, suspended, PFC’d and running hard and fast, I might be able to get back to the Stagea. There is also a GCG ball bearing high flow and a split dump/engine pipe to go on.

BTW, It was pretty useless running more than 7-8 psi without the DFA, the standard ECU R&R mapping made it slower than when it ran 6 psi.

Cheers

Running 12psi. All fully tuned.

Full exhaust, fmic, NEW oxygen sensor (for best fuel economy), pod filter, sitc, safc, ebc etc etc.

Get over 420km per tank (hitting resevre), with 160awkw.

Great pick up at 5000rpm, no splutter for me - a nice safe tune, rarely do I let it stay at 12psi....... (heat factor = dead turbo).

Got a spare turb' sitting on the shelf.......

[KR.15.YS]

my car is completely stock except for the 3.5" exhaust, front mount, and pod filter.

plannin some more mods down the track.

but I don't wanna go crazy.

keepin in mind that this is my daily run about family car.

if my other half had his own way it would have had a turbo upgrade and computer by now.

but in the end it's my car and the foot comes down...

lol....
