Default Update: Super RB Evolution into Stage 3 type Twin Turbos>>> - 10-25-2014, 10:25 AM

All,

As many of you know we have been testing a new breed of turbos into the N54 platform dubbed the Super RB's. With testing we have found a couple things we had suspected we would find long ago and had hoped it would not be the case… but unfortunately found that it was. That is the new large inducer (19T+) turbos simply do not get along well with the plumbing environment they are being expected to perform in and ultimately do not last or make the gains we'd expect (or hope for) when they are utilized. This said it has been deemed the appropriate time to stop turning a blind eye to the other gross N54 turbo plumbing system limitations and evolve the setup into one that can sufficiently handle the airflow and power potential we are trying to accommodate, which is the Super RB evolution into Stage 3 Twin Turbo Setup.

Keep in mind if you want a nice increase of power (without the extra costs affiliated with even more hardware and fabrication), retain visual OEM appearance, and other "hassles" you really need to just keep considering the Standard RB's or Billet RB's. There are always options we can accommodate with these setups but the masses need to understand that with or without clipping, with or without the thrust upgrade, with or without the billet wheels; the results will still all be very similar.

Time and time again we have found that our traditional RB Turbos perform better in the real world than any other known in the N54 community, we do not need to explain why this is only but to let the product to continue speaking for itself (as it has for years). We are still willing to cater each order to your liking in these regards but the amount of gains per the "tinkering" involved is pretty much marginal in the real world in this application, each combination we will see ~124-128mph traps with pending on the aggressiveness of the tune/vehicle weight/conditions/etc, with more gains to be had with modified inlets as we have seen recently as well (it has just been released about a customer pushing 625+rwhp with standard RB's with modified inlets). Simply put the OEM N54 compressor inlet and outlet plumbing is very insufficient to do much of anything above what is known to be already and needs to replaced so have any chance in getting desirable results.

So for those looking for more power, willing to pay for more product, willing to lose the OEM visual appearance, and to ultimately get more gains reliably; we will now be testing something else new for you. We have decided to go ahead and follow through with the vision we had years ago and are very happy with what it has became at this point and are very close to completion. This includes a full TD04HL-19T+ Twin Turbo Stage 3 type setup incorporating every bell and whistle available including the proper TD04 compressor housings and affiliated inlets and outlets, also guaranteed to be the most elegant Stage 3 bolt on solution that can be expected to be had with the real estate limitations we are working with on the N54.

In the next week we will start updating this thread with some pictures, but we are fairly certain this will capture a audience that is very interested in the progress of the project. The biggest progress we are going to see will be due to the leaps we make and not necessarily the minute fiddling that is often mucked about with… so we are optimistic that this leap will get us into the area we wish to be in.

As always nothing is for sale until we feel we are comfortable in the results of the testing. Costs are unknown. Release date is unknown. Production cycle is unknown. Fitment across models and drivesides is unknown. Etc. The details are unimportant until we confirm results via pending real world unbiased results. We have poured a lot of time and money into this setup but wish to only provide it to customers when we feel it is going to be something they want.

Please do not jam up our email asking for discreet updates as they will be deleted, we will provide them as we see fit here. We just felt it was time to disclose what we have been quietly working on for the past couple months, and that we are very extremely happy with the direction we are finally heading for making a higher powered setup that we believe will be more reliable over time. Doing things the right way is the objective here.

Thanks,
Rob

Your products speak for themselves and I think we all appreciate you telling it like it is. Upfront and honest. These qualities set you worlds apart from certain other turbo manufacturers and when I'm ready to take it to the next level, I know exactly where I will put my business and my dollars. Do this community a great service and keep doing exactly what you're doing. We thank you.

Sounds exactly like tuningwerk turbos. They do 720HP (flywheel) on their 1M with pumpgas (NO E85 nor meth), built engine though. 0-200km/h in 9.x sec.
They haven't released any info about the turbos, but I have seen it and it look like a 19T or 20T wheel with bigger ***** from turbo to fmic:

What kind of power levels can we expect? I read everything but didn't see that that was unknown Looking forward to updates. I have been waiting a very long time for the so called super RB's, so i hope this will be even better and not TOO pricey lol.

Will this be good for the AT guys, or will the TQ be too high for the AT?

No. That pic shows that the plumbing they are using is OEM style connections, which essentially means they are still utilizing OEM TD03 compressor housings. Ours is using TD04 compressor housings and properly sized in/out plumbing, aka Stage 3 type system.

Expectation is a true reliable TD04 style 650-700rwhp. As for the AT: The short answer is that if that is a concern then you may want to buy a MT car, consider the possibility that you may likely need to upgrade the AT, or just don't buy something that makes more power than it maybe able to handle. Turbos only provide the power, which we all want more and more, so if that is what you want you just have to expect the worst to support it. Expect the worst and hope for the best.

I've seen the difference preturbo inlets make on other platforms and its actually astonishing. I gaurantee you'd see improved performance on anything from maxed out stockers to upgraded stock frames.


Have a single turbo and/or tired of burning up O2 sensors? Ask me about the new ADV O2 sensor retro kits!

Haven't pulled the trigger yet because I was waiting for your Super RBs but now I guess I'll have to wait a little more for these!! Can't wait to see what you come up with!

I've run RB's for over 2.5 years and love them every time I start my engine; OEM feel, more power, killer on the track, no issues with reliability what so ever.

Rob, I note your comment in the first post "Fitment across models and drivesides is unknown". I do want to move to a stage 3 twin setup, when there is one that can compete with current RB's in not just power but quality and reliability also. I am so envious of all you LHD car owners out there where development is going to make you spoiled for choice. Rob, no one considers RHD cars in their design; I ask that you please please please keep us in mind with this development!

RHD and other fitments have been considered but for now the most important thing is to complete the setup and see how it performs and to see if the market is there. At the end of the day if it doesn't directly bolt up to other models/drive sides it can be made to work for the other models with enough determination, but again will cross that bridge when we get to it.

Out of curiosity, what was the issue with the Super RB turbos? Did they fail after limited miles of use or was it something else?

The issue is the plumbing fore and aft the turbo. They are not real welcoming on large inducer turbos, and cause them to self destruct fairly quickly when pushing them hard with it all in place.

This setup will not be very similar to RBs (ie. Stage 2) as nearly everything changes to new hardware (ie. Stage 3). Not sure yet, it is just far from the radar even considering at this point as we still need to finish developing it and test it first.

I'll say this... I like VTT. I've helped his customers hit some nice goals. I've also SEEN and helped your customers hit nice goals. My wastegate rattle like a mofo and I'm watching the stage 2+ closely, I'm no early adapter unless I'm building a "kit" homemade to my standards. That being said, I do not like clipped wheels, they sacrifice transient response and are a means to an end I would like to avoid, but want 20T airflow. Make it happen man.
