Dyno Tuned With Gtss Turbo's

[GTR032]

Hey,

Today I finally got my GTR tuned with my GTSS turbo's and MINES dump pipe upgrade. MRC in Castle Hill who installed the turbo kit a few months ago did all the tuning work on it.

Just for information value current mods on car is..

GTSS turbo's

Mines dumps

HKS front pipes

Trust PEII cat back

Cam gears

Profec b boost controller

Power fc

Apexi pods

So still standard intercooler, injectors, pump, air flow meters etc.

As the graphs show it made 275kw's at 1.1 bar and pretty good 12:1 air fuel ratios. Boost is very steady after the initial slight spike. Car feels a whole lot better. Only downside is the air flow meters are maxed out, and to be expected the oil temp does creep up quicker and go higher. Nothing that a cooler wont fix. At this stage the fuelling and cooling will probably stay as they are as I dont have the money at the minute to upgrade, but all is very safe none the less. It did make a peak of 294kw's but he pulled some timing out just to be on the safe side.

Overall very happy with the performance and service of Mark at MRC.

NOTE* If anything is thinking of doing GTSS turbo's on their GTR DO IT!! They're awesome street turbo's. And to those with cams aswell even better!

looks good jono. that is a nice amount of power in a street GTR too enjoy it!

[shonen]

awesome....so 300kws isnt out of the question with bigger, injectors and cooler and z32 afms ?

I think I spotted you on george st right in front of the cinemas on saturday night......

I know your plates but I didnt get see them so yeah unless it was another silver 32 with Work rims hehe

[Tommyk]

do you have a torque curve you could post up ?

im still shitty with my state of tune

[OZ GTR35]

Looks similar to my GTSS well done, these turbo's do come on boost nice and early.

Anything else planned?

[Blitz]

Drop in some poncams Jono, you know you want to

Thats 275 rwkw isnt it?

[Tosh]

Thomas....

I was with Jono on sat night, did you shout out at us?? I could swear

I heard my name being shouted out as we drove past there....

[shonen]

hahha I would have...but my windows were down....and yeah once I reacted with the windows it was too late...I had already passed

[ferni]

Nice, Is that rwkw or awkw?

Looks like you're hitting full boost/1bar boost around 4200-4300pm? williamsf1 said he was getting 1bar at 2900rpm!! Surely that can't all be cams?

I'm about to put a set of these on so trying to find out as much as possible. But i'll probably run mine at 1.3-1.4bar.

Whats your max injector duty on stock inj?

[Moanie]

w00t!!! congrats jono!!! when you heading to the creek to give it a run?

that's interesting about the boost. mine with stock turbos makes 1 bar at ~3700. it seems jonos is at ~4250. still not bad, but i would have expected under 4000.

Yeah i'm interested to know how mine goes when i get them fitted. Give me a month or so and i'll be back.

[ferni]

What power did you make on std turbos btw?

[Beer Baron]

me or jono? mine makes 253 rwkw on stock turbs. actually it now makes 247 as it was slightly retuned for a little more mid range (cost a little up top).

Yep rwkw.

The stock injectors surely induce that 'lag' so to speak, the tuner said it could be slightly better but the stockers are pretty much close to their limit. Cams would be the other big contributor.

Don't know duty cycle of the injectors, if I get my hands on a pfc commander i'll see then.

Mine made 252rwkw's on the stock turbo's.

<{POST_SNAPBACK}>

Didn't pick up a printout of the torque curve but i'll get one as soon as I can.

[Ashy Larry]

Awesome Work Jono,

Now to get me some GTSS's

Do you have a fuel pressure reg?

How do stock injectors induce the 'lag'? Would be good to know what duty cycle your hitting - you don't have a h/c?

252rwkw sounds pretty close to what i made on stock turbos. Do you have adjustable cam gears?

[Mintie]

good to see jono..r u upgrading ur gear box too???

[ferni]

the gearbox can handle more power than that. just don't abuse the gearbox and don't put a solid centre clutch in it, i know from expereince
