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

First of all - what's ".73"? Is it a reference to HKS housing or something?

Second - thought are that we should wait for real-world results. As of now this turbo does not seem to justify the price difference between it and conventional 3071. On the other hand price difference is not that big, 1392 USD for GTX3071 + housing that you can buy everywhere vs. 1448 USD for GT3071 [data taken from ATPTurbo site].

Personally I think (at this stage I have no real world data, so I can only assume) GTX3071 is the best of all medium-frame GTX turbos currently available and is not worse than GT3076. E.g. compressor requires less revs to reach similar airflow to 76mm GT compressor , and in general seems to spend shaft power more efficiently. The biggest concern of course is that GT3076 and RB25 combo is tried and proven many times, as is GT3071, whereas GTX turbos have yet to prove themselves.

Are you sure? I'm not questioning your experience with GT3076, but some results I've seen for 3071's so far, particularly with .63 housings, look awesome in that they have factory-like boost threshold with 1.5 or more times power and make more torque everywhere, which I think is the key to a nice and fun street setup The same definitely can not be said about GT3076.

.73 is the exhaust housing. It's a custom housing AVO can do.

I'm starting to think BW intentionally uglied up their turbos to scare off fanboys.

It just looks untidy...

Possible fitment issues to. The wastegate actuator is hanging in the breeze a bit.

Needs a billet blow off valve cover too :ph34r:

Who gives a toss how it looks if it meets the performace criteria. I hope they wax garretts arse to the point where garrett actually starts doing some real r&d and giving customers something better than 3rd rate service and dated designs.

Well, just like GTX Garretts, EFRs still have to prove they are as good as BW advertises them to be.

I wodner if 7670 can be bolted to the factory RB25 manifold. Good prices though - GTX3076 costs 1400 + IW housing 350 bucks , so it's 1750. EFR7670 can be bought for ~1850-1900 with 0.83 T3 flanged hsg, and this price includes boost control solenoid and antisurge valve. :thumbsup:

Bit it really should have T4 twinscroll IW housing, so 1950 for turbo + 1000 for suitable manifold. I need to allocate some money on this...

I think it's great. Stops all the ricers from buying them (ppl who generally don't have the proper supporting mods and give bad names for turbos by posting dyno graphs). I know ppl who refuse to consider one due to the looks of the turbo. Silly people!

Yet those people will happily what a "nice" looking turbo on the side of an RB25 with badly scractched cam covers with no coil cover and wires running everywhere.

GTS-R style low mount manifold looks better than any turbo anyway

Same, hence the comment. Though Noel took offence :)

Unless something even better comes out i will almost certainly be getting an EFR turbo next. Thinking about a high revving rb20 32gtst with a 7470 for some stupid reason these days....low mount of course to hide the elephant man looks of the comp cover

There's an EFR thread with some results in it scott

There should be results in the next day or so of an STI which first had a .82a/r GT3076R, then replaced it with a .82a/r GTX3076R, and now afaik has a .83 EFR7670 going on it :)

Should be VERY interesting to compare!

Alot of good info on nasioc forums already.

Any more real world results on these turbos?

+1 for in particular on a rb25 with a 3076 compared to a gtx3076 really need to see if there are benifets after talking about them for a while.

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.

      First thought is to use a ram mount (to hold the ipad) + windscreen suction mount. The arms on the ram mount can be as long as you like, should be able to position the ipad pretty well with that setup.
