Hypergear Turbochargers and High flow Services Development thread

Uploading some results posted from a NZ fan today. I think the NZ dyno HP determination equation is in DIN.

Latest ATR43SS2 internally gated bolted to the factory manifold on S2 RB25DET.

- Greddy knockoff plenum
- 1000cc xspurt injectors
- 80mm bar and plate intercooler
- custom 3" piping
- g4 plugin ecu

Final numbers were 331kw @ 500nm at the wheels on 18psi boost on

Hey Stao

What can you do to my old ATR43G2.5 -> Which was sent back to become a now SS2 a year or so ago. if u remember.

Is it worth sending back for some loving?

Im making a healthy 300+rwkw at the moment.

Can you get that close to your atr45? or is the housing to small for that?

Want some extra juice for Racewars next year

Yes can upgrade few things to make more power. I can't remember what configuration it might be in. Best email few photos first.

Any update on r33 high flow prototype? I'm keen to get this on my E85 Neo setup if it proves to be similar response to the SS1PU.

[hypergear]

Thats about as good as they can get, I'm out of turbine housing for any better efficiency compressor.

[benl1981]

Me to so is the r33 high flow prototype in full swing production now?

Looking to use it on an r34 neo also and maybe e85

[hypergear]

Yea. cost $990, includes large internal gate assembly, high pressure actuator and oil line.

[Manuel Kasko]

From your experience, is this as good as the SS1PU
Is it just as responsive and can it make 300rwkw on E85?

[hypergear]

Yes. probably make more power then SS1PU.

With the atr45 is there a recommended dump for best results? Brand name Bell mouth, China or a split dump?

[hypergear]

3.5 inches turbo back will work te best. Bell mouth. Or 3 inches with exhaust tee.

[kingtube69]

Stao any recommendations for exhaust brands/models and dumps that suit that?

I've found the Tomei Expreme is 3.5 from the cat back but NFI about the dump pipe

Cool cheers, have you got a handful of atr45 install photos? Wouldn't mind seeing the intake setups on r33

Hi Michael,

I have this turbo on my R33 - I'll post some pics below. If you want anything more specific let me know and I'll go pull the airbox off for you

Overall can't see much so it looks stock (No problems with cops). The only thing that stands out is the silicone joiner and the braided oil line for the turbo. Will be invisible with a heat shield on it.

10mm spacer was needed for it to clear the block and you will need 45mm and 55mm studs if I recall correctly for the turbo to manifold connection.

Must have a metal intake for the turbo too.

if anyone wants my #scotty_nm35 3" intake with 3" to 4" silicon reducer & an alloy extension piece (if you are deleting your AFM), it's up for sale soon...

Mine's a little different as it doesn't have the BOV return and the breather line it mounted slightly different to delete the factory hardlines, intake mates up to the factory airbox (if you need it).

[kingtube69]

I'll take the AFM delete pipe if it will mount up to the factory airbox depending on price, I just went MAP and ceebs making a delete piece myself

[Dose Pipe Sutututu]

it's just silicon and a short piece of alloy? hahah

[kingtube69]

All good, I was thinking it was like the HKS afm delete that connects to the stock box

[Dose Pipe Sutututu]

buy one of these things, then connect silicone to it then to the alloy piece.. done!

[kingtube69]

Oooooh, I was just thinking about that.

I have one sitting at home anyway

Thank you!
