    SS2 is a well matched item to the HTA3076. You can run a comparison to that using both the standard BB and CBB Alpha version. The HTA item has identical boost plot to the BB Green standard version. Add Camshaft and more boost it will match that HTA3076 power. If you are wondering what HTA3076 is like on SS Alpha housing with stock cams, then you are looking at it now: (SS2BB V SS2 Alpha CBB) SS3 Alpha is a Duel ceramic roller bearing billet turbo, I've mentioned it is physically larger then the HTA3076 item. That is why it made more power on a less modded car. As if you are comparing a 600HP turbo to a 500HP turbo.

    Updates of some unusual turbocharger. The Schwitzer turbo out of a early model Toyota land cruiser diesel. Turning that into our Billet TD05H18.5G is a total workout in ingenuity. Here it is: Expected to gain about 15% more torque without adding much lag.

    Disconnect catch can and let breathers breath freely into atmosphere.

    The T04Z is good enough for 400rwkws+ on E85. I will be using the .82 SS Alpha turbine housing for this, so you still keep your 1.05 rear just in case. The best is if you can leave the turbo with me for few weeks for me to figure out the best nozzle angles and I will get some dyno runs done with the new housing. My prediction is about 25psi around 4000~4300RPMs, and about 430rwkws. If you don't like the final result, I can send the turbocharger back to you in original housing, no charge.

    more testing under way for internally gated version.
  6. hypergear
    Sure I can. it will cost you $650 including the turbine housing, and if you don't need it back in a hurry I can do some dyno runs with it for comparison for your final decision.

    it shouldn't as the turbocharger doesn't use any water, water flow through out an different layer of the casting. If the layer broke for what ever reason the sump should be filled with water. you can test it by pressursing one end of the water line to the turbo while block up the other. If the turbo don't have any abnormal shaft play then it is probably also ok.

    Just clear up some confusion as proportion of people don't understand how the alpha turbocharger is any different to traditional turbochargers. If a traditional turbocharger is built for 600HP it will be, drive and act like a 600HP turbocharger in all rev ranges. At same HP, the Alpha turbocharges, drives as a 400HP turbo from 0~4000RPMs, 500HP turbo from 4000~5000RPM, 600HP turbo from 5000~7000RPM. So it will always feels like a baby turbo to drive while produces decent top end. At any given freedom of variable nozzles angle, the turbocharger is only capable of producing a proportion of it full HP capacity. For example if nozzles are fixed at 10 degrees a 600HP turbocharger will only produce 300HP maximum, 30 degrees at 450HP, 45 degrees at 500HP, and 50 degrees at 600HP. When controlled by an actuator with preset actuation levels, on given boost, this turbocharger will expand it self from a 300HP turbo to a 600HP turbo as engine reves out, then contract to a 300HP turbocharger off acceleration. It repeats this process throughout the whole driving course. Most of our budget went into developing and research for newer innovations. This is a giant step forward for modern performance turbochargers.

    Well then, I'll be happy to print you some results. As for OP, using the Alpha turbine system, I can work with your current CHRA and knock off about 1000RPMs of its current lag without altering the peek power of the turbocharger.

    The dyno reading above does not shown any boost plots. And by looks its not any where close to 24psi. Let's put it in this way. The ss3 alpha is a 3071 down low and 3582 up top. If you believe 3582 can pull 400rwkws on stock cams then that is what you are seeing. On the same time the ss2 alpha makes 22psi by 3500rpms and make 385rwkws. And I guess you don't believe stock response 320rwkws either. They are all on stock cams, ans the profile in the turbo are bigger then what u have in mind. The intergration of the technology is new, so no one yet owns one. More results is just a matter of time.
  11. hypergear
    Well I'm not convienced that you can get full boost with a gt35 rear ended turbo to spool on a stock rb25det with factory head, cams and cam gears to reach 24psi before 4000rpms and crack 400rwkws. I have already trailed that using a tinny 52t 71mm comp wheel. It doesnt reach 20psi till 4400 rpms. That was in a .63 rear also. So you are not going to get any thing more responsive then that by switching to a larger compressor wheel and bigger rear turbine housing. As for the ss3. I can give you some comparison with other branded turbos from trents dyno which will give u an idea of where it sits.
  12. hypergear
    True, he will need cams to get this sort of result. The 407rwkws that I've archived is on stock cams with lesser boost. I don't know the exact wheel profile of the HTA item, how ever SS3's turbine wheel is larger then whats in the GT30s. It should pump more power on your setup.
  13. hypergear
    I found Pump 98 is tinny bit more responsive, probably due to the extra heat: Boost response. 98 (Purple) V E85 http://www.hypergearturbos.com/images/dynosheets/atr43/atr43ss2/290612/e85boost.jpg

    On E85 there is usually a 40kws of gain, if the tuner knows what he's doing. On E85. Unless you put some cams in it. Or using factory cams: A GT30 based turbocharger can not make over 400rwkws A GT35 based turbocharger make get over 400rwkws, but can not make 24psi (minimum requirement to reach 400rwkws) any where near 4000rpms. You will need our Alpha turbo systems to do this. And trailing result of 407rwkws with 24psi by 3700rpms using factory cams and E85.
  15. hypergear
    Yes you are right. Its actually from Alfa Romeo . Alpha sounds too american. Lets stick with American wording for now. To produce this it has to out perform the SS2 Alpha version which I think that is extremely good. Will post result after Trents get back from UK.

    If it can get up to about 340rwkws then that would be sweet. Means about 300rwkws on pump 98. I drove it on low gears light throttle around the block, it felt like a stock turbo more then any thing else. Be interested to see what the dyno says in few weeks time. If works well this would be an excellent turbo for Rb20det and SR20det engines.

    Some updates: This is the SS1PU Alfa version. I will make Alfa version stand for our most advanced turbo systems that delivers the ultimate power and response. VNT, BB, CBB, Billet wheels, customized bell shape inner profiles and etc will all be parts of this project. As in the turbocharger above: I have trimmed down a older SS2 comp wheel to produce around the 320rwkws mark since the turbine end is only capable of flowing up to 322rwkws. Which I rather turn the additional load into response. I want this to be the most responsive 320rwkws any thing can ever produce.

    Actually after modifying S14, 180sx, 300ZX, Soarer and R32. Modding R33 is like walking into heaven, this is probably the easiest car to modify, with plenty of parts available, and getting power out of the Rb25det is so easy. Compare to the rest the R33 made the most amount of power with the least amount of money spent.

    7 speed DSG, there are also reports from the wet boxes failure, how ever the problem isn't as severe. Apparently they stuck in gears, rapid shifting gears, case sudden lose of power or sudden acceleration. VW declear a problem with the Auto controller software, that causes the premature wear of its clutch plates and fly wheel. how ever the issues are yet to be rectified. And that is on a factory tuned vehicle. Seems to be in certain VW from 2009 ~ current.

    Hooo The VW Golf R. Remember to buy the one with a Wet box. Don't go any where near the DSG dry box stuff. They are horribly bad. The Chinese government made VW to do a huge recall on all their cars with DSG dry boxes, and many of my VW clients and tuners I build turbos for have reported this problem. They also run direct injection, you can run them on Audi R4 mechanical fuel pumps and injectors. There isn't much ecu options apart from few people that makes fixed data flash tunes. I think Link G4 recently made some thing for older Golf models, but doesn't work with current models. VW modification cost lots of $$$$ and the end results are no where near to a stock Rb25det. If u got the cash Buy my test rig its already been modified and all you have to do is drive it. I need garage room for a GTR.

    might be jammed external gate or broken gate diaphragm
  22. hypergear
    It: would be every thing apart from the turbocharger. Pretty sure I can make it work. So interested to give it a shot?
  23. hypergear
    ss4s compressor is in 85mms compare to the usual 82mms. I will be using that with a .82 turbine. That should be plenty for a 2.5l with a large external gate.
  24. hypergear
    Let me see how the SS1PU goes first. I think for some thing that is already that super responsive, by making it even more responsive might rise surge issues.
  25. hypergear
    SS4 is currently offered as a Ford XR6 BA / BF upgrade. Its similar to a GTX3582. Expecting to make around the 450rwkws mark on E85.
