Open up the rb25 dyno thread and hit search and put in gt3076 and gt35, gt3582 for some results to compare to

Well in that case I have no idea! heh

is it possibly they don't do many RBs and have gotten it a bit wrong?

Lee Wilson. The owner raced his own r33. They have tuned HEAPS it's like 40% Subaru, 20% skylines 20% Holden's/fords. The odd porches, rescently s couple r35s etc.make up the rest.

Dunno,it is possible its a lazy tune and has more tweaking that could benefit it..

its also possible they dont want to push his engine for fear of liability issues..

maybe the engines f**ked, did you get it checked before you threw a huge turbo on it??

how is your car set up shifty..exhaust ecu injectors etc..have u told us and i missed it??

Full 3" Turbo back. Coilpacks. Cai. Gizzmo boost controller. Sards 850cc sidefeeds. Link ecu. Fmic.

Entire engines been checked as I had a couple issus. Crank angle sensor was stuffed. Then there was an issue with the head. That was taken off and sent away and fixed. Everything else was checked. They had it for 10 weeks. I'm worried about them using an avo actuator.over a garret one.

They already said they don't want to push further until I have internals.

The GTX3584RS will support roughly 850-880HP on a 3.0L (maximum rpm of ~7500-8000) at a PR of about 3.1-3.3 No chance of getting 1000HP out of it, not unless it can be done at a PR of 2.75 and even th

^^this what im talking about Ash but yeah it doesnt explain the lazyiness down low i know..

How is correctly setting up boost control not wanting to push a motor?

AVO realistically have done nothing special in the world of performance for many years. Least of all anything RB related.

It simply comes down to poor boost control. Why a HD Garrett actuator wasn't used just like everyone else uses i don't know, but its the logical place to start.

Oh :ermm:

So if the actuator is the problem why has he not been informed of this and how do you know it wasnt a HD one...have i missed something???

What controls boost?

Actuator & wastegate.

What else can it be on an internal gate turbo?

People have GT3071's come on 800-1000rpm sooner, making the same power and are reliable as it gets. Setting up boost control on purpose to be laggy is not logical at all, so if that's whats been done then I'm shocked @ such a decision as it has nothing to do with leaning on a motor.

Heavy Duty. Look mate sitting here posting 100 posts a night about it - it's going to fix it.

Walk into AVO, ask them why boost response/setup is poor and inform them you are not happy with it and it should be more responsive.

If I can't come here and ask 100 questions a night what's the point of joining this community? I walke.in today. That's how o got the chart. They said they will try and adjust timing. Is it a general concensus to go to garret HD actuator.

Can't fix boost control with a keyboard! ;)

Timing has little to do with how laggy your car is mate. Timing won't make as much of a difference.

If you took the reference off the actuator (holding the gate shut), i'd be surprised if you didn't see boost ramp up noticeably earlier.

Obviously ONLY do this on a dyno under controlled conditions as boost will continue to spike (as the gate is 100% closed).

Lol @ keyboard fixing boost issue.

Yeh ill tell them to swap to HD garret regardless.

Well don't just go in there saying that mate. It's just going to cost you more money.

I've never seen an AVO actuator so its possible they can put more pre-load on it.

But then given you are running an EBC, perhaps it's not quite set-up correctly either - or its both.

I'd simply be asking the question first, give them a chance to fix it or see what they say.

If it's not satisfactory in your eyes, or you just want a 2nd opinion for peace of mind - then go somewhere else. RE Customs, Sabaddin Automotive, Chequered Tuning - All 3 very reasonable workshops that have worked on many skylines/RB's lately & not too far from you/reasonably priced.

I've asked. There only answer was "we will try adjust the cam gears. That's all we can do"

Cheltenham is Vic isnt it? Dont you have the flagship ECU for SAU's flagship tuner?

Get your ass down to Status and tell AVO where to stick it. I have never used status but this forum shows nothing but good rep and someone punting a BIG market on poor business ethics. In lamens terms he is too well known on such a large scale to not do right by you, it would cost him too much business to get bad feedback on this forum.

Also, Hypergear may be able to sort you a better actuator for cheaper than a garrett HD item if yours falls through.

Well there is your answer from AVO if they think it is a cam gear issue.

Talk to one of the other shops, show them the dyno charts and see what they say.

It was more of a "that's the way the turbo s, we will see if can gears help. But it wont shave too much" can sub par actuators display issues like I'm seeing? Lazy boost response etc?

Sounds like you are getting shafted by AVO due to your lack of knowledge. Some companies will take a easy pay cheque!

I had a thought regarding this - ShiftTys, how does the car actually drive from your perspective? Does it seem that laggy?? If you put it in 4th at say 2500rpm and floor it, what rpm does it reach say 7psi, then 15psi (if its not too dangerous to do that)?

Were you present for any of the dyno runs? Looking at those plots, it makes me wonder if there was a very quick sweep rate used - like 6s or quicker for a run? Thats potentially too quick to give an equal comparison to most dyno plots out there, and potentially too quick to replicate what you might experience in the real world.

      yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?
