Powertune Australia R34 GTR Vspec2, 2.8L 703Kw/950hp@wheels = 1000hp@engine

[LuckyGTR]

very nice , VERY nice car my dream right there

[AH_HUH]

that looks awesome. i can tell he spent 10 hours easily just by looking at it. i was close to doing the same thing but it would draw too much attention if i get pulled over by the police. lol.

Do u guys have e85 fuel in canada at petrol stations?

[gtrjon]

nope. a few places across the border in the us do however. highest pump grade is 94 octane

[LuckyGTR]

no unfortunetaly , highest gaz i can get over here in MTL his 94 petro canada,

i have couple of picture of how he did it for the cluster
keep in mind the OEM OIL PRESS N WATER TEMP dosent work cuz they are in the haltech , but the GAZ and torke gauge still work perfecly he did a re wired and everything like a champ









custom blue LED were installed too in my whole interior to match all

i love haltech **** they are ******* amazing

[Prenihility]

Thank you =)

The exhaust is custom made by Powertune Australia out of mild steel. The muffler i'm using on the end of it is a Varex system that opens and closes a butterfly to reduce noise when cruising around town.

The sound that the car produces does have alot to do with what you mentioned but also the type of turbo and waste gates.

There are 3 other r32 gtr's in AU also built by Powertune that have the exact same setup as this car and sound exactly the same. Same stroker kit, same cams, same turbo, same exhaust design, same waste gates, same sound.

Ooohhh...

Please, do tell.

Unless, of course... it's a company secret.

The turbine..and wastegates, huh?

Well, from what i've read, i know your're running two Tial 38mil external wastegates, correct?

Not sure what to even take a guess at, in regards to the turbine... ?

Oh... because it's single turbo?

I sure hope not... because personally, i wouldn't do that type of setup.

Twins on an RB, always.

Response, baby! Although i saw it haul on the track as well. It moves very well with that single turbo tune.

If it were a single turbo 2JZ; Supra. Hehe... wouldn't be good news. Interesting how the RB out-...responds the JZ, even with a single turbo.

I'd say the best thing Supra owners can do is install a toilet into the driver's seat, so they can... be occupied while the turbine spools up.

Big, single turbo Supras. Less than ideal driving experience...

Hehe.... sorry, i got a bit carried away. Just had to mention that.


Unless of course it isn't even that? Something to do with the turbine internally, perhaps? Not the fact that it's single turbo?

lol, yes it is a single turbo. to be exact, its a Precision 7175 ball bearing type. Listed it in the specs on the first page i believe.

my input in regards to twins and "response" would be that it i've been down both paths and i personally would choose the single. in some cases, response does not need to be sacrificed if the right turbo/engine combo/tuner is chosen. taking into consideration that the type of fuel also does matter in how early or late a turbo comes on.

Here is a good example showing both power curves on 98octane and e85 fuel.

Here is a video of my r32 gtr running a smaller Precision 6265 bb turbo. take note how early it comes on and how long it stays on boost for. Also forgot to mention, the engine is still a 2.6litre with only hks pistons and cams.

http://www.youtube.com/watch?v=fLByiseWcDk&list=UUHnnOKt-TjcbtkmhoaEBrIA&index=31&feature=plcp

Previously, my r32 gtr ran a twin greddy td05 turbo kit which made the same power except was very laggy and ugly to drive.

[Skym]

I like.

So you're using the GM? ethonal sensor trick??? (amazing watching it adjust in real time).

Depends on what someone means by "response". Do they mean boost response (how quickly it produces full boost), transient response (kick in pants / violent feeling on or off throttle), engine response (how quick engine revs).

From what I understand, twin turbo smoothes out the transistion (flattens power curve), so basically not a sudden rise in power when exiting corners (makes car snaps sideways). At least that's what I have noticed on dynocharts and I would think turbo size plays a role in it (use smaller turbo's with twin turbo setup to get better transient response, boost response, produce same amount of hp as a bigger single turbo).

HKS have a response vs turbo size vs hp chart -

I am using a Haltech ethanol sensor in my car. In the pump i have seen around 60% to 85% ethanol.

I suppose in a racing application a lot of variables come into play, but in building my cars the aim is to have a fast reliable street car. this car weights in at 1850 kg / 4070 lbs so its no track car.

as for twins and singles... it really does come down to what you want from the car to begin with and how much experience a workshop has to make it all work effectively.

[RCKSTR]

This video on the dyno was when i had just finished running the car in 2011. The car is way overdue for another dyno video to show the current power.

oh dear lord... very nice mate!!!

[PurpleStreak]

Thanks for sharing..I've enjoyed your car vids for a while now..

What kind of chassis reinforcement is it sporting to sustain this level of power?

@gtrjon

Huh?

@LuckyGTR

WTF are you all about?

Did i say something funny? I don't remember telling a joke.


@AH_HUH

Ah,i see now.

I THINK i understand the two wastegates also.

Twin-scroll. Manifold division, because of turbine housing division.

Two wastegates. ?

As i remember MINE's build with response in mind. Their R34 anyway, and their cars are usually twins. While on the other hand, here in NA, you'll see tuners such as Titan building big single turbo monsters.

Single turbo seems to be more prominent in general, for street cars.

And over 1800Kgs? Good GOD! Doesn't the R34 weigh in at 1560Kgs?

I remember you got some fabrication work done. But... that alone couldn't have been the culprit?

An additional 190Kgs.

Your GTR gained quite a few pounds. Tell it to lay off the chocolate .

the only extra reinforcement i've done to the car is an upgraded kansai tower bar. the rest is just standard.

this elephant of a car keeps gaining the kg's because i refuse to cut anything out. lol. street car. air conditioned.
the extra weight comes from the new turbo, gearbox, intercooler, clutch, transmission cooler, extended sump etc that has been added to the car. the custom diffuser at the rear only weighed an extra 2kg's over the standard carbon fibre item.

then on top of that... add driver which i am 95kg. so the car literally is close to 2 tonnes when driven around.

[Prenihility]

Damn... well that explains it.

And 95Kg, man...

That's over 200 pounds.

Someone works out...

Well, thanks for being nice and patient with everyone, AH_HUH. Especially me

That's what happens when an audiophile hears a sound they like.

Lovely...

Now let's just hope that Hayabusa on steroids sounds is achievable with twins, and not as much power as your monstrosity (900+ Kw, woah), high lift cams (thinking 272-IIs, 10.5 lift)... Revving just over the 9000RPM range? Your said your GTR can get taken to 10 grand. But, you didn't specify what the redline is, exactly. I'll just go ahead and assume it's the low 10,000 range. 10,000-10,200 or so.

Errrmm... no resonator should do the trick.

But i doubt that applies to performance exhausts. They probably don't even exist in those things.



Anyway, thanks, brother. You've been very informative.
