    It looks like a old KKR1000 turbocharger. You can't fit that on stock exhaust manifold and hope every thing bolton.

    Should be able to customize turbine housings. Depending on what sort of car it is for. Further development into the ATR28SS Alpha Series based my S14 with a SR20det motor using BC S2 cams. This is a base line for CBB SS2 Alpha version, Vnt is not current engaged. Final result of 302rwkws on 24psi P98 fuel. SS2 Alpha Base line compare to Standard SS2: Makes the same amount of power, but is slightly more responsive. Base line Vs Garrett GT2871R in .64 rear: Its currently making 190rwkws and 21psi @ 4000RPM. It drives pretty good the way it is. The goal would be matching the GT2871 curve without losing any top end.

    Grinding shaft at moment, probably two weeks away. If you wish to send me the compressor wheel I can definitely build them with the new exhaust wheel.
  5. hypergear
    It will still be in the 9 blade design, just over sized.

    Just a quick update. I'm in the process of making a 55mm exhaust wheel for SR20det motor. That is a mm a side bigger then your GTRs turbine all around. I will doing some evaluations ready, they should be the solution for your current issue on the Rb2630 and pickup more mid / top rang torque also.
  7. hypergear
    Power figure would be similar to below:

    I've built a a pair for Chequrered tuning's LS1 V8, that is mainly getting the advantage of running extra timing for the high comp V8. I'm awaiting on the manifold for my GTR, So I don't currently have a result for this particular turbocharger. Are you looking for some thing that suits a Rb20det? How ever I have do have an result using the exact same compressor and turbine, except been in a VNT housing. You can reference to the ATR43SS4-Alpha model. That would give you an approximate peek power and boost to power ratio.

    We can definitely high flow them in ball bearings, how ever there isn't any point doing so as it makes no differences in end result. We make up own exhaust side wheels for very specific purposes so our high flows are not in standard Garrett wheel patterns. This mainly makes the turbocharger been able to discharge good volume of air while working with restrictive factory housings. That stabilizes boost control across all rev ranges, while keeping knock level under control based on a minimum of 12 degrees ignition advance in upper revs using P98 fuel. There for, the engine makes power happily with factory drive ability that has very limited boost or power tappering in upper revs. Using our standard 21U high flow, 260rwkws is usually archived based on 19psi of boost, 280rwkws would be the maximum capacity internally gated at 24psi. 24psi is usually reached by 3500RPMs, More power is achievable if a proper manifold and external gate is used. That makes a very drive-able high performance street / track car. You can find all results on our high flow threads, the latest few pages would be from our current development.

    Great drifting Result sent in, This is our ATR45 turbo on an Ford XR6 BA. Final result of 400rwkws on P98 fuel internally gated bolton at 19psi of boost.

    Have a quick ready of my thread. It contains pretty much all the information you require to know. The page is indexed and linked from page 1. So go to page 1, pressure Ctrl+F and type in 21U for pages contain details of R33 Rb25det high flow, or OP6 for pages contain details of R34 Rb25det Neo high flow. http://www.sau.com.au/forums/topic/261613-hypergear-hiflow-service-continued/

    The previous owner is a farmer, he knew nothing about cars, it was sitting in his garage for a long time. He said he only driven it to his mechanic for a oil change every 4 month, and clocked 4000KMs for the past 5 years. He's wife made him to sale it. I'm more interested in the Rb26dett power and response thread. I will be starting with a single setup once the manifold is ready. Too much hassle getting E85 when needed, This car will be running on P98 fuel.

    Fully stock 98 model S3 N1 R33 GTR with cat back exhaust. 269rwkws @ 15psi factory ECU. Front drive shaft has been removed. Running against usual spec GTR R33. Boost: AFR:
  14. hypergear
    This is power vs a normal GTR33 on stock ecu: Boost vs Stock R33 GTR: And AFR Timing, ignition, fuel, AFR, Pretty much every thing is spot on. Std GTR 33 tuned with PFC was getting 245rwkws on 14psi. While this is fully standard with a cat back exhaust. It felt very different to drive compare to other GTR 33s I've looked recently, I was expecting around 180rwkws not 270rwkws. So well this is my base line for this GTR.
  15. hypergear
    But a highest reading out of a stock GTR on this dyno was 207rwkws on factory tune. My boost curve appears to be laggier also, but not as laggy as the N-1. Pretty much spot on with -9s. But every thing is stock. Its the only Navy Blue GTR Trent's ever seen either. I always gets stooged with cars that makes stupid power.
  16. hypergear
    Funny my new gtr 33 just did 270rwkws with front drive shaft taken out. Fully stock with 3inches turbo bacm exhust. Not sure if the last version of gtr33 had some tricks into its sleeves.

    Some updates. This is from our OP6 standard high flowed running on R33 Auto (Kane_R32).

    On a Rb20det, This is much better then high flow the factory T3x turbo.
  19. hypergear
    Usually with any of my turbochargers assume plenty of clean oil is supplied they do not require to be rebuilt. There should be a mm of side to side play and nothing in and out. 740ccs should be good enough for close to 400rwkws on E85. Please PM me your address I can send you a sticker. Thanks.

    For this particular twin high flow project, I'm targeting 350awkws while chasing factory driving ability. When air is been compressed it also tries to expand. Tall and packed compressor blades havs the advantage of throwing out greater volume of air based on lower shaft speed, at high shaft speed how ever, the blades becomes restrictive. To increase efficiency, we must creating greater total induction area, as you've noticed an radius has been added to the inducing blade, as well as a customized compressor hub, with longer blade length. It is a prototype wheel, there is no guarantee of been an better performing wheel until further evaluations conducted. Comparing cast and billet wheels. Not any billet wheels can out perform an traditional cast wheel in its size. I have personally seen many poorly designed billet wheels, and made some bad prototypes my self. It comes down to the extend in understanding of how each and every individual components of a compressor wheel might be affecting the final output. Similar scenario applies to exhaust wheel also.
  21. hypergear
    Some updates. This is the first prototype wheel made based on a standard GTR compressor wheel. The size of it is in 58mm, with 8% additional induction area. We should be once fitted, it should produce similar response as the factory turbochargers while making 8% of extra power and torque. The blade radius is also made to reduce this "turbo shuffle" problem that is common on larger simultaneous twin turbo setups. STD GTR33 comp wheel Our new billet GTR compressor wheel. But either way, I'm not a fan of simultaneous twins. The goal would be fitting an ATR43SS2 to stock manifolds and build a kit that suits every thing else as well as re-engineer the SS alpha series for the RB26dett engine. The factory twin high flows will be evaluated some stages in between.
  22. hypergear
    If you want more power, do a high mount setup, and externally gated it. Cam shafts are not necessary.
  23. hypergear
    That should be 240rwkws, our billet ATR43ss15 will do the job nicely. You can check out my thread or site under ATR28, the G2 and SS15 SR20det result should be very close to the RB20det in terms of response.
  24. hypergear
    is the 400HP in reference to engine or wheels?
  25. hypergear
    In this case the SS-2's exhaust wheel is probably the one to go for, I can use 68mm SS-15 compressor wheel which is equivalent to 71mm 52T Garrett, while been more responsive.
