Hypergear Turbochargers and High flow Services Development thread

[hypergear]

That is the CHRA that we normally use for GTR turbocharger high flowing. We will need your factory housings to carry it out. Or we can supply you 2x complete Garrett turbos. I will PM you a quote tomorrow.

[geraus]

so we can run the turbos with no blow of vavle?? by blocking up our stock one?

When i got my car it had been defected for an atmo bov so the previous owner had just blocked off the hole where the bov was, still seemed fine to me.

It is strongly recommended that you do keep a BOV. stock or aftermarket. The Surge pressure that comes back when throttle is shut can do lot of damages to the turbo.

[hypergear]

Below is the commercial version of ATR43. This is now available. The turbo comes in 4x different profiles:

ATR43G1: 450HP in . 58 / .63 rear

ATR43G2: 480HP in . 58 / .63 rear

ATR43G3: 520HP in .63 Rear

ATR43G4: 600HP in .84 rear

It is designed to bolton to your stock manifold, dump, water, and oil drain. Braided oil feeding line is required and priced at $80 with turbo. All turbos can be built with a Garrett GT Ball bearing CHRA depends on consumer's budget. To fit them to factory intake and intercooler pipes you will also need 2x silicon pipes one in 90 degrees 2inch and the other in 3inch straight.

ATR43's .58 and .63 Turbine housing is interchangeable with All ATR28Gx High flows that we've sold. Will gain instant power increasement specially to the ATR28G2 based R32 / R33 xIU high flows, Should have No issues archive upto 270rwkws with supporting moods.

why does it need a braided oil line? whats wrong with the factory one?

[hypergear]

The stock oil feeding line has a oil restriction valve. It is not suitable for sleeve bearing CHRAs. Also Garrett GT CHRAs runs off a different thread.

[paulr33]

how is sleeve bearing different to ball bearing

most guys here just assume ball bearing as thats what stock OEM is

[hypergear]

Sleeve bearing turbo require greater amount of oil flow. The bearings needs oil pressure to float. BB does not. BB turbos has roughly 10% better in response. Sleeve bearing turbos are cheaper to build and service.

ATR43Gx are made to be interchangeable with Garrett GT3071, GT3076, and GT3582 GT CHRAs.

So really comes down on the consumer's budget.

What is the price to rebuild a set of GTR turbos in both bearing forms?

[W0rp3D]

ATR43G1: 450HP in . 58 / .63 rear

ATR43G2: 480HP in . 58 / .63 rear

ATR43G3: 520HP in .63 Rear

ATR43G4: 600HP in .84 rear

Are these figures rear wheel or fly wheel?

What is the price for the G3 and G4 in both sleeve and bb?

[SS8_Gohan]

those are fly figures, which i think is the standard way manu's spec their turbo's

[W0rp3D]

I assumed that, just wanna be 100% sure.

To high flow GTR turbo using GT2860RS BB CHRA is $1350 each. And we can supply the Garrett unit brand new for $1400 so might not really be worth doing. To high flow with Sleeve bearing CHRA in identical spec is $800 each turbo.

How much are the ATR43G3: 520HP in .63 Rear and the ATR43G4: 600HP in .84 rear for the rb25det, when should you be able to see full boost? and what is required for a direct bolt on to the rb25det?

[hypergear]

The final decision on RRP is $1250 per unit. Response depends on the HP Profile. Bigger = more power, more torque, more lag.

[HR31_RB20DET]

Hmm, interested to see how the ATR43G3 with the .63 Rear would go on an RB20, how would it compare to say a 3071r?

I'm currently running a highflowed VG30 but looking for a little more power than it's currently making.

[paulr33]

um be careful quoting prices here, this isn't trader / for sale?

are there any issues with cooking the bearings at engine power off vs ball bearing?

He is a business trader and this thread was set up by him to tell everyone about his products, i dont see a dilemma with putting up prices.

[hypergear]

Thats all cool. If I'm bending any rules I will fix it up. From experience BB turbos are more likely to get cooked. Most sleeve bearing turbos receives greater amount of oil flow and this is built built water cooled. So they are pretty fine.

The current Ball bearing turbos runs oil feeding pins on the top with 20thou wholes on both side, Not sure why Garrett designed it that way. But in lot of cases they gets filled from dirt in engine oil which allow bearings to cook. Then they becomes very expansive to overhaul. about 80% of Ball bearing overhaul jobs we currently getting has failed in that manner.
