    cost $1600 for both that is with usual cast wheel or $2000 with 60mm billet wheel.
  2. hypergear
    For the 300zx guy: Yes can run the Billet SS1 profile. Or much bigger if you don't mind lag.

    Pardon me in the last post as I got the translation of wording wrong. the correct wording for the pump is centrifugal pump.

    Once throttle is shut, engine no longer burst hot air into turbine housing. At that instance turbine shaft is rotated by inertial energy. The turbo compressor is a centrifugal pump, so the only way for majority of compressed air to escape is the same way they've been drawn, by forcing the compressor wheel in opposit direction. Compressed air at that point slams back against the compressor wheel, depending on the size of impact (or how much boost is dosing backing) the size of the compressor housing and blades. while forces cancelling each other, the medium in transferring and absorbing this energy is the turbine shaft and thrust bearing. o Which is also why there is a two phase collar in side a bush bearing turbocharger as well as the opposing angular bearings inside a roller bearing turbocharger. Edit: Pardon me in the last post as I got the translation of wording wrong. the correct wording for the pump is centrifugal pump.

    When the throttle shuts, compressed air will bounce back trys to rotate the compressor wheel backwards and escape from the induction pipe causing that Tuuuutuututu sound. This is not good for a turbocharger as the compressor end is not made as a driven component for the turbine wheel, and I occasionally get BA turbochargers with twisted shafts from owners whom wanted dosing noise. So in this case a BOV is recommended. How ever I do find that boost take less to build up between gear shifts with bov blocked. To me the best way to minimize the induction pressure drop is by shifting it quicker at high RPMs.

    To get a compressor as large as this to work you will need to remove the actual gate assembly and then install a 38mm disc while machining the wastegate gate whole to about 36mm. Even thou Its still very small for the compressor setup which means the turbine side will go red hot. How ever that should stop the overboosting problem. Example of some thing that we often to do XR6 turbochargers:

    Well I don't have this problem the high flow profiles I do has been welly sorted and trailed. The configuration of this compressor appears to be too big for the turbine side. But yes I can fix it.
  8. hypergear
    The car got cam timing and etc to sort, so looking to see final results after its all been fixed. Alternatively you can send it back for the latest G3 upgrade and see if that makes any changes. Some thing makes more power then a T67, Its been already made. The ATRL25.5G 399rwkws with 23psi of boost on stock cams all within 7000RPMs. Alternatively you can use our new SS2 turbocharger that has the same response as the SL220G while making lot more mid range and 10kws extra top to a T67.

    Halando my car is heaps faster then yours. Also I noticed (ignore in case it was the sound of some thing else) you've got a habit of revving the engine before going to gear. That Rev is too long, engine's dropping rpm as the car's just rolling. G3 can be updated into the latest turbine and compressor setup. I will keep pricing to minimum.
  10. hypergear
    Yes that was one of the things with the older G3 with none FNT or type A turbine to be improved. The current G3 is much better at it, and the SSxx series are even better again.
  11. hypergear
    My results are what the turbocharger's capable of making in a proper built setup, and there are many people who's done that made within the range. There is nothing wrong with Trent's dyno either as I've run on other dynos before and after his the difference is within 4kws. There are variances in every one's cars just like Copycutter, you all just witnessed the performance differences by making a better setup, and perhaps work of a better tuner. If the aim is at a very fast car then it needs to have that setup. No one is talking about power figures from a T67 on a Standard manifold and run it internally gated (247rwkws with drop of a cliff). Alternatively drop a SS2 or a G3 to whom ever's working T67 setup, that would again be a totally different boat of figures. There is a chain of relations, but not a direct relation between a turbocharger, trap speed or power out put. Far as turbocharger building and development, we practice the Japanese theory "Kaizen" . How ever there is nothing more I can possibly do, other then the part that I build.
  12. hypergear
    Stock manifold was 57kws behind a my current high mount setup using running the same turbocharger. It will be good if you can come for test drive with my car during your next visit in Melbourne. If top end power and torque has nothing to do with trap speed while only decrease end time, then is there a actual connection between trap speed to the turbocharger. Or is it more gear ratio related? as in it is limited to what ever it might be on 5th gear at 7000RPMs.
  13. hypergear
    Dame. Thats the closest one to the city. Where does majority of Melbourne people go for drags now?
  14. hypergear
    A proper aftermarket manifold with ext gate vs factory manifold. On paper the torque and power curve is very different after 5500RPMs and when driving it my current setup pulls very hard till red while it doesn't on stock. One the other hand tyres , wheels, driver skills and etc all takes effects so there are a lot variances. Well we are not comparing to other make of cars. Trying to get my car to the drags. Not sure whats happening to calder park this days. Seems they are no longer opening for weekend drags and I've been trying to ring them for 2 weeks and no one's attending phone calls either.
  15. hypergear
    Really need a high mount with a large gate. The difference in higher speed is huge. You can run that with the G3 you've currently got which would satisfy the 330rwkws mark on P98. Or tun a ATR45 or a SL25.5 for 350~400rwkws. Pretty shame WA got no E85.
  16. hypergear
    That was the exact problems when I fitted one of those manifolds into my test car. That is a China manifold. and it cost $150 landed from China made in steel, I believe the seller painted them black or added an external port to it. I almost imported 100 pieces of them my self few month ago. But after trailing it as well as some proper Australian made manifolds I gave up. Building quality and performance is no where near. So in the end i'm just happier to offer recommendations and provide results for every one to make up their own decisions.
  17. hypergear
    Proper high mount with an large external gate comes handy for high speed. The acceleration in high 3rd and 4th gear is totally different compare to stock manifold internally gated. When I run the ATR45 on 431rwkws flooring 5th with speedo doing clock work, car kicks side to side and felt it wants to skit and roll so I backed off. Proper aerodynamics really comes in handy around there.
  18. hypergear
    That is a pretty good result for 17psi of boost. Tried boosting it more?
  19. hypergear
    There is no E85 in WA yet. So 650cc will do fine for 300rwkws+ on 98. PFC is fine. If the car needs to appear stockish then high flowing factory turbo is preferred. and it can support towards the 270rwkws mark. Stock AFM is ok for upto 250rwkws mark. Z32 AFM for any thing above.
  20. hypergear
    I can't high flow your exhaust. But yes can certainly high flow the factory turbocharger. For starter you can run standard or SS2.5 or G3.5 high flow depending on HP and budget you are going for. I can do a special bundle deal with adaptronic plug in ecu also. It have a built in map sensor so no need for afm. If you are not looking for any thing above 230rwkws then ask Toshi to remap your stock ecu and run factory AFM. injector wise, stock injectors are ok for up to 230rwkws. ID1000s are nice, Unfortunately they are not drop ins for R33s, I personally run Power enterprise 850ccs, or Jpec 650s are also ok.
  21. hypergear
    This is video track footage from John. Running a standard high flow from 2 years ago. It should be the last run of it as its getting a update to the latest SS2.5 profile. car is currently on 260rwkws.

    My side mount manifold was the very first one he's ever made. I had a deal in mind having them produced in quantity how ever the amount of time and parts required for this to work is far more involving then initially planed. It didn't work out. Based on the manifold that I've received, bare in mind it was the very first one ever made. I score it 70% out of a 100. Manifold does hold the turbocharger approximately on the same spot. which allows the factory dump pipe to be fitted as well as the water lines and drains. The manifold pushed the turbocharger towards the chassis side by 25mms running that with an actuator and a standard actuator bracket becomes extremely difficult. How ever if external gate is used then that is no problems. The bit I really didn't like was installation. Because it was all squashed together there are no room for tools. I had to remove factory rocket cover getting my spanners in, and skimm them so I can just turn the bolt. I don't think there are much can be done to this. But Once its installed its fine. Performance wise it made more power then factory and any China manifold could ever reach based even running lower boost. How ever still fall 30kws behind his proper high mount with a 50mm gate. Weighing up all factors, even tho it is a very good manifold, my vote still goes to his high mount with external gate.
  23. hypergear
    ^^^ Yes the adaptronics are pretty good ecus, good part is it support map sensors, flex fuel, boost controller, turbo timer and launch control. Which saves from getting a bunch of little pieces. and we do a special bundle deal on them with any turbocharger related services or purchases. I've just bought 20G worth. and sold many in the past that haven't had any returns yet.
  24. hypergear
    It made 40kws more then standard Based on a ATR43SS2 turbo. I'm getting over the whole street legal thing. It just comes down to how you can fool a cop, obviously smart cops can tell from those cover ups while stupid ones will defect you for having an "stock intercooler" or having wholes (obviously stock cooler piping) on the chassis . Plus you can't go to EPA without a stock manifold, turbo, and exhaust. So get your self a good high mount ex gate setup, quite exhaust, and enjoy the power while you can. lol

    The SS2 for RB25det is only in T3 .82 FNT rear with RB's IWG assembly. The latest one is slightly more responsive: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-360 and required lot less duty on the ebc. So it will work better with factory manifold internally gated.
