  1. Following up the ATR45SS-2 test conducted last year Dec on the hottest day in Vic of the year that made 472rwkws @ 28psi running out of fuel. That test has been completed few days ago, maxed at 552rwkws @ 38psi. It seems like factory engine head is finally maxed out. Dyno run below consist of ATR45SS-2 V ATR45SS-1, the smaller one is a much nicer turbo to drive with plenty of power band. Will be conducting some more work with current high flow series next and see if current record can be broken.
  2. Yes I was get around 170psi on a healthy Neo motor as well. None Neo motor was sitting around 160psi.
  3. Yes PWR has a pricey vertical flow cooler for the R34. I've already trailed it, its no different to the blitz.
  4. G4 comes with one size bigger wheels. roughly 25kws difference in power compare to the G3. Trying to push 270rwkws out of blitz return flow is like pushing 520rwkws out of stock cams. So yes to ATR45SAT.
  5. Alternatively you can use standard G3 profiled 21U high flow thats bolton to factory location with minimum fabrication work. Made 282rwkws on P98 fuel and 330rwkws on E85 internally gated, super responsive.
  6. I don't think u will see much more then 270rwkws with a Blitz return flow cooler. Fitment of it is on Video below. O nP98 fuel, Power wise G4 high flow maxed towards 300rwkws, while ATR45SAT maxed at 322rwkws. I'm placing an bulk order for PWR 600x300x79mm coolers at a discounted price. if any one wants them let me know.
  7. ATR45SAT BB model internally gated is recommended. U will need a proper cooler kit for that power. I can supply PWR front mount coolers if anyone's interested. Thats the same one as I'm currently using on the test car.
  8. Another result to share. R33 GTST running one of our ATR45SAT Ball bearing turbos externally gated on E85 fuel. Stock standard Rb25det engine with head studs, and valve springs. Car made 414rwkws @ 24psi tuned at Chequeredtuning Victoria.
  9. Rear end looks like that. cheers. thank you.
  10. Yes I do have Vband and out housings in .81 size. I can custom the turbine so it will still be responsive.
  11. Hi, Recommended turbo is our ATR43SS-2 ball bearing model in T3 .63 Vband rear housing. it will be capable of making a super responsive 350rwkws.

  14. I've used an Mishimoto 600x300x65 mm years ago on my R33 GTR it wasn't any better then the stock cooler. That was later upgraded to a 600x300x100mm which worked ok, car made 410awkws. Pretty much as what you would expect from an cheap ebay cooler, and it was only half the price back then.
  15. It should be super responsive and makes same or better power. .82 Single or .84 TS is recommended for RB30det engine.
  16. Some video to share from Monday's dyno tune. Car now has two Walbro 520L pumps installed with 12mm fuel lines. Still using ATR43SS-3 turbo, except I've installed a .82 turbine housing for this particular test.The final result was 482rwkws at a point that no more power could be made with this model.
  17. The power figure of the ATR45SS is lower then expectation, while both wheels are bigger. There is a 22 degrees difference in ambient temp differences. I will be going back to them at a later stage. I now believe the differences of E85 and 98 is under estimated. Without actual data of this model on P98, so Its just going to give a very rough estimate.
  18. Probably 360rwkws mark on P98, that would be a different boat compare to E85. ATR45SS are bigger turbos, They were however tuned in 41 and 46 degrees days, I will be doing bit more work and get back to them soon.
  19. Hi. For Rb25det, S1 turbo will do fine, no need to go for OP6. So G2 will be something that supports stock fuel system, while G3 and G4 would need to work with upgraded fuel system and programmable ecu. G3 is capable of making up to 280rwkws on P98 fuel, while G4 is capable of making up to 310rwkws on P98 fuel.

Car made 474rwkws @ 28psi, E85 fuel. With 265rwkws @ 4000RPM, Fuel system currently maxed.
  21. Hypergear Atr43ss-3 Turbocharger Test and tune 474rwkws @ 28psi fuel system maxed. Should be seeing 500rwkws+ once fuel system sorted, and still seeing 265rwkws @ 4000RPM.
  22. Far as turbos go, with a .64 rear and .60 front that is very possible, you can even up size them to GTX3071R. I found factory exhaust setup is very restrictive, so if you can run two short 3 inches pipes hanging out side of the car along with all other supporting mods you should be able to get there.
  23. Pretty good result to share, From one of our ATR45SAT BB turbo externally gated on E85 fuel. Made 407rwkws @ 20psi with plenty of head room. R33 GTST with self built Rb25det engine:
  24. Looks like a GT35 with a T04Z front wheel on it.
