    All the corners in the .82 B rear housing has been rounded off, The flange area can't be any bigger, its been traced through the gasket. For the Billet TDxx series to work probably there is a need for a proper exhaust manifold, external gate, and a front pipe. I'll get them sorted very soon.

    Cheers for that. The prototype billet td06 performed well and proven reliability after few track days. it is now to stay and available for only $800. After comparing data collected of other TD06SL20Gs + SR20dets, Our version is more responsive with much better mid range. I'll be doing some further evaluations with it on my Rb25det once I have my high mount manifold made. 2ndly we will be starting on making our external gate, using imported stainless steel castings with all machinery work precisely carried out locally. This gate has a fully adjustable pressure chamber, comes with both adaptors, clamps, and 3x different springs in combinations for 10psi, 14psi, 20psi and 20psi+. This gate is $330 on its own, or $250 with any turbochargers.

    The SS1PU is not a GTRs. 2ndly if you are comparing td06 to a GTRs its never been compared on fair grounds. Install your td06 internally gated in a stock rb20det manifold plus all the EGR and road legal crap you would normally expected to run on a stock setup, The TD06 would not perform any where near a GTRs or a SS1PU. All supporting mods counts, The turbocharger does not take all the credits.

    Yes I can do that. will cost you $150 for that setup, you can send back your std actuator with bracket for $100 refund.

    This happens when the turbo loses its turbine wheel, you can probably hear a slight ruddle at the cat too.

    because hig I presume it is smoke from burnt oil. It does sounds like a turbo issue. At high RPMs there are greater amount of thrust load on bearing collars causing greater amount of shaft movement or gap, allowing greater amount of oil escaping from the rear end seal. Plus in 4th gear it takes longer reaching 7000 rpms which also means more time given. So there is a leak just the amount its leaking and the given time for leakage is not great in lower gears, which you might not be able to notice it while driving. Check and make sure engine is not over filled, and oil drain is not blocked. Remove the intake pipe and have a feel of the turbo shaft movement. Strip the turbo is easy. you can get every thing down from the top.

    Its pretty interesting as the SS1PU is a tiny turbo compare to the G2.5 and G3 while they makes same power level in some cases, with the same turbo it returns a mixed bag of results. Recap on hardware, all there is are: cheap 2.5inches ebay cooler piping kit with 600x300x75mm core 3inch xforce turbo back with no cat and straight through type of mufflers 4inch induction pipe BOV ProfectB EBC. Split fire coil pack They are all average john stuff, I was getting easy 260~290rwkws on pump with three different tuners and dynos in Vic, and that was with a stock built engine on factory exhaust manifold.

    The G3 and G2.5 in .82 Type B Rear housing was holding boost pretty steady during the trail. I was getting under 1 psi of a drop with a Profect B. It had pretty much identical response, I think some how yours might have more back pressure. if playing with the actuator made no differences I would check pressure differences by plugging a boost gauge just after the turbo and compare it to whatever it reads out from the inlet manifold. You might find:

    Please refer to post 6125. They are identical turbochargers, both with .82 type B rear housings just different actuator setup.

    We are talking about 1.2psi gain, not a mojor but there is a difference, notice the shape of the curve too. The 20psi actuator still had 3psi drop. this sheet was taken when using the same turbine housing compare to: The SS1PU probably had the most boost drop internally gated, this actuator setup should work well with that.
  11. hypergear
    Well if you runit on stock manifold as a bolt on turbo internally gated on that housing its not going to make lots of power. GTX3076 is ideal for external gate. Also I didn't see metail induction pipe in your mod list, you will need a 4inch metal induction pipe for that turbo.

    Had the car tuned again today and we had some pretty good out comes. All results today are still based on the ported factory exhaust manifold. First of all the twin actautor setup tested and the result went exactly as expected. the amount of boost drop was halved. Graph below shown twin actuator setup from today in orange while blue was the single setup from last week: This was the single actuator setup from last week with figures: As we can see boost drop with twin actuator setup is 1.2psi, while boost drop from a single is 2.6psi. As for turbine housing concern I've used a .82 type B rear working with the SS2's CHRA. the result was 3 degrees of extra timing up top, with exactly 21kws of gain. Orange is from today, while blue is a custom profiled .63 rear housing from last week. This combination is probably best SS2 option working with stock exhaust manifold.
  13. hypergear
    Sorry I don't think you can run 5psi on it. if it is then check actuator preloading.
  14. hypergear
    This topic has been covered here from memory. that cause massive boost spike as once separated the internal gate is virtually sealed up in a cylinder, making pressure by pass difficult as your waste gate can not open up to 90 degree. Run a 3 (3.5 preferred) inches bell mouth dump for the best performance.

    Its different to a big can actuator, I've used it while ago and I couldn't get rid of the boost drop, the current high pressure actuators worked better. Big can or high pressure actuators will only work to certain extend, the stronger the actuation spring is the more boost spike occurance in mid range as exhaust manifold pressure at that point is not as high as what they are in upper rev range. The Actuator is acting against both inlet manifold pressure and exhaust manifold pressure, The EBC can bleed off inlet manifold pressure how ever has no control over exhaust manifold pressure. Pressure at any points of its distribution remains constant, So in this setup the advantage of having two actuators halves the force generated through exhaust pressure. The end result in theory should half the amount of boost drop or better. I've taken the car out for a thrash with both actuators hooked up in one boost source, they are now sitting at 18psi instead of 16psi on a single. So hopefully it holds 20psi flat on the factory exhaust manifold.

    I've spent couple of hours on a bridged twin actuator setup with some scraps I had. In theory once both actuators gets connected to a single boost source, the valve open pressure stays the same as having a single actuator, how ever the strength acting against the gate doubles. I hope I'm on the right track and my innovation holding boost steady through out the whole rev range.
  17. hypergear
    lol. no that is just the plug that seals of the screamer pipe to the gate.

    It has to be in a particular angle as else the comp cover will hit the manifold. I've added few spacers under the actuator between the bracket. as long as the rod is perpendicular to actuator it self it will actuate fine.

    Updates: I'm getting some steam pipe bolton manifold and high mount manifold made overseas as I'm typing. I should have a prototype received by mid next week for trailing and testing. Those manifolds will be available for $300 to our customers assume they perform as expected. It appears a larger turbine setups would perform better on factory manifolds, I will trail a SS2 in a .82a rear housing on current std manifold for some comparison.
  21. hypergear
    You can get Scotty or Abe2 to make an induction pipe. check page 264 Or if you have a Adaptronic or a map sensored ecu I would just run a 3inch metal pipe with a 45 degrees silicon hose and a pod. Check page 89 You probably find all your answers on page one, I've labeled all the important discussion bits in reference and linked to according pages.

    It looks either wastegate is unsealed or VCT is not activated. Ask Sean to change the VCT settings through the ECU and see it response to power curve. 2ndly the actuator has to be removed for turbo installation and in many cases the pre-load was let by the operating mechanic (many believed they shouldn't be tensioned) or not been corrected adjusted after installation. Drop the cat, have a play with the EBC, that dip and claiming back up shape looks strange. To get around the 280rwkws mark it needs to hold around 20psi up top. Further more, pretty much all results came out of the test car are on aftermarket manifolds. I will see Trent next week to trail a larger turbine housing for the SS2, which should compensate a little working with stock exhaust manifold.
  23. hypergear
    Visually look for damages on the wheel blades and housings. Have a feel on the shaft, if its bush bearing there should be under a mm of play side to side, BB should have none play. Both types of cores should not have any in and out type of shaft play.
  24. hypergear
    Refer to my E85 result on a milled out stock exhaust manifold. If you take 40kws out of that been the 98 result then that would make it just under 280rwkws. and I'm sure the manifold that I've used had much more porting done. Try and have a play with the actuator pre-loading, drop the exhaust, and run abit more boost through it, and you should get just around there. Alternatively get a brae exhaust manifold and ex gate setup. Picks up 30kws straight on less boost. Refer to page 299.
  25. hypergear
    It looks alright for the boost level given considering its only at 16psi peak, and the most it can make out of stock exhaust manifold internally gated is 280rwkws, I would use a EBC to increase boost level, also double check with exhaust on and off pre-cat.
