Hypergear Turbochargers and High flow Services Development thread

[hypergear]

Good day. For the best result the .82 rear housing is recommended working with a ATR43G2/3 CHRA on a RB25det. It is noticably laggier compare to a .63 rear housing, but it will be able to hold steady boost to red line.

The .63 is be able to get you over 330rwhp (250rwkws+) with similar response to a stock turbo. How ever it is not capable of holding high boost. you will find it always drops to about 17 psi towards red line unless you run an external gate. I've tested it my self and done lot of reading through forums and webs, and I've seen this happening to all GT30x .63 internally gated turbos.

Personally I would recommend you to run a ATR28G2/3 with .82 rear housing, even there is little bit of lag down low it will still produce plenty of torque to give you this hard pull sensation. and when do have better mods you can get power just by increasing boost level.

Ps. Crans in case you are reading this post. I've sent you a ATR28G4 with .82 rear housing instead of .63 as you were after 280rwkws+.

Also like to add one more thing. Our ATR43's .82 rear housing has T3 flange and 6x bolt pattern dump for OEM R33 upgrade. This can also be purchased with any high flow options for $350 additional. Or $500 for any one who wants to upgrade from smaller rear housings.

[hypergear]

Is any one interested to purchase a evaluation unit of ATR43G4? its in identical spec as a 3582R in .82 bolton rear housing internally gated. I will do one unit only for $1500 with oil feeding line, and I will refund $400 after receiving its dyno reading. The car must be good enough to run on 20psi of boost with supporting mods. Perferred Melbournese, and dyno tunned by Status or Phase Auto.

Your about 2 months too early, doing a basic rebuild on an engine now and will need a new turbo when its done, will also be getting trent to tune it once its done.

Some photos of a fresh built ATR43G4 in .50 Comp with .82 rear. 600HP rated (Looks similar to CN KKR but very different ) . This will bolt on to stock Rb25's manifold and dump. Generic actuator is likely to have problems holding high boost on RB25det. We are intergrating an 38mm external gate into it for greater boost control. I will post up photos of it as we move along.

just reporting in.

got my standard r33 turbo flowed last week. just to the next power level ~230rwkw.

only after the beerings went, i wasnt searching for more power.

but going full metal wheels, with the track day action was a must.

install

pain in the ass. water lines need stuffing around. bending, unbolting, swearing, skin off knuckles etc

be prepared for trauma.

power and torque are up, but so is the lag.

i'm getting use to it, having not driven a garret or hks i cant compare. but it feels like it pulls harder than stock.

track performance

definite benefit at philip island

undecided of benefit at winton, have to swap up gears with more power, loosing time. have to keep the turbo above 3.5k, means high revs in

2nd and spinning the tyres. lost of fun, but not the fastest way around.

Niceeeeee

HI John:

Great to get some track side feedbacks.

With bigger and heavier steel wheels it will obviously be laggier. Its a turbo so can't get both power and response on the same hit.

I understand that you are racing in stock class, But I'm not sure if OP6 R34 turbine housing is classified as aftermarket upgrade. Strongly recommended if If not, that would give an extra 40Mn of torque, and with injectors (not for your current class) should see 260rwkws.

[Crans]

Stao,

280rwkw sounds good, how far will she go if I chose to later on change to an external gate setup?

Quality of the turbo also looks pretty damn good. Dump pipe welds are of good quality aswell.

Only problem is the VBand clamp you sent is too narrow to fit to both the turbo and dump at the same time.

I sent you an eamil about it about an hour ago.

Hopefully she will be sitting on the 25 shortly.

[hypergear]

I'll get another one measured up to swap the one you have.

It is strongly recommended that if you do run a external gate. I found external gates holds boost lot more steady. I will inform you tomorrow when I get the Vband checked.

Hey tao, how big is my rear stock housing? is it .52? i forgot?

^^^^^

Is this offer still available? I'll pick it up this weekend. Mine engine is ready from rebuild.

[hypergear]

Sure. Please call before drop by. Turbo is ready for pickup.

With out going through this whole thread, do you have a bolt on turbo that has successfully produced 260-280RWKW with out any dramas?

Hiflow or other? I'm interested in the above but this thread seems like a running development?

[hypergear]

The ATR43G3 .82 is good for what you need it for. I've managed 273rwkws with it on a RB25det with 5 cracked pistons based on 17psi of boost.

I'm currently experiencing actuation issues for it to hold high boost. just like this thread here:

http://www.skylinesaustralia.com/forums/Gt...21-t289241.html

The part No. came back as a CAT actuator that is made for 26psi application. I've ordered the same actuator which due for testing next week.

Kwickr33 I will install this actuator to your turbo if you are happy to do some evaluations. or please wait for about a week for me to test out this new actuator. I will post up results once its done.

[geraus]

yes make sure you have the supporting mods and you should achive it. I have a highflow i chose to have a respsonsive setup i get fullboost at 17.5 psi.

with my supporting mods i got 233kws but i had leaking issue's.

tc.

Do you do highflowings for VG30et turbos too?

Ive got one, but struggling to find the specs of it.

Can't tell if its 16v, 45v2/3 etc...

All i was told is that it was from a single turbo 300zx (Z31)

its got:

14420v0300-01

410581-2

JL5950

written on it...

plus: .48 AR on the hot side.

can anyone help me out?

cos id be interested in a highflow in a few months time...

Yes we can high flow this turbo to archive about 450HP. It will cost $880 including GST. Every thing fit back the way it was. You don't need any new oil line or water lines for it to work.

[StealthX]

Ok cool thanks!

Can you give me some info on the turbo though?

45V what?

was size housings etc?

thanks.

[hypergear]

that is to actually high flow your turbo. We will be build a 3071 52T spec sleeve bearing CHRA then machine your housings to suit it. So you get back a brand new turbo inside your factory housings. You need to send your turbo in to do that. and it takes in general around 3 working days.

Just a little bit off topic but that turbo has been used on either a 4cyl or a twin turbo V8, do you still have the manifold attached and what was it used on?
