Hypergear Turbochargers and High flow Services Development thread

yes i noticed the oil once i put the pic up but no oil anywhere else, i will check it tommorow. Doesnt seem consistent with oil, looks like it may be a drip or something

[hypergear]

There is absolutely no more area that could be taken out. its been CNC mill out according to factory gasket.

The corners of where the gaskets goes over has been tapered out and rounded off.

Its been give out as much clearance as it possibly can be inside the Nissan 6 bolt fange.

The adapter flange is pretty free flow, made no differences on dyno.

The oil must've been dropped on as every where else are completely dry unless its been sitting upright for some time.

[GeorgesR34]

I don't think mine had the large area cut out when I bought it back in 2010. Does the new flange make any differences in power?

[hypergear]

Made pretty much no differences for the power level I've run it at. All new ones made this year are fitted with the cut out flange. How ever you are welcome to send back the adaptor to get it machined out to the current spec at no cost. Put it back on the dyno and see if that makes any differences.

[GTScotT]

do it george, back to back!

settle the debate for everyone, just 2 power runs and some tooling

[KURTIS34]

Looks like you had fun getting it off, is that 3 snapped bolts still stuck in there?

How old is that version of the g3? I wonder if they are all like that?

I didnt take it off. Mate took it off his own car. Took him ages. It was funny watching him actually. I know he is gonna read this Hahaha.

Tao do ur own turbo's have this lip? Do u Think it will be a restriction?

It was heaps of fun , the snapped bolts are the easy ones , the pain in the ass one was the one that didn't snap.

I believe oil was a result of a dip from feed line when fighting to pull out of the bay.

I'm interested for some data supporting the effects from the Type B .82 rear housing working with a existing Type A .82 setup on stock manifold. My expectation would be no lose in top end power with 400RPMs gain in response, totally different drivability. This apply to All ATR43/PU high flow's .82 Rear housing including Type A FNT and older None FNT versions.

hi everybody,

if your interested in some hypergear gear check out this . , my setup seen 280rwkw

thanks

Any one whom's interested in above turbo for a Bolton setup on factory exhaust manifold is recommended to have it send in for the Type B turbine housing conversion. Unless used with an proper aftermarket exhaust manifold.

[Manuel Kasko]

Should I be doing this for my SS1PU?

[hypergear]

Yes I've tried that in the exact same print for the SS1PU. It became super responsive but only made 247rwkws.

That method of FNT arrangement is made to trade off top end power for response. Its fine for the Type A G3 as the power level its capable is beyond what factory exhaust manifold can flow internally gated.

Also should go back for few more dyno runs to see if the new clutch made a difference in performance. Generally there will be a difference if its is noticeable on road.

Edit: stao posted the answer

Stao, have you sold any of the new g2.5's you recently posted up results for?

I'm interested to see results on a stock exhaust manifold

Edited May 20, 2012 by Mitcho_7

[hypergear]

Not yet. Its still on my car. The maximum it can do on stock manifold will be around the 280rwkws mark. Unless E85 which can push it further.

[t_revz]

You seem to have become a hater of the stock manifold in recent weeks Stao. At what point do you think it becomes a hindrance and are you now recommending customers to change it?

[ARTZ]

i think around 300kw is what everybody has been saying here for years...

it will push beyond that but its not ideal

[hypergear]

280rwkws internally gated is about ideal. There is a noticeable difference after going to the Brea manifold. I think Trent did mention a difference between 2~3 degrees of timing in certain areas. which stock manifold would heat soak, pin with power band nosing down, while aftermarket kept on calming. making a big 330rwkws bolton turbo was a mistake.

[ARTZ]

yeah but didnt you say , E85 changes everything?

so if you can get a turbo that makes a comfy 280 on a stock manifold with PULP..it will comfortably pump over 300 on e85

[t_revz]

Hoping to get that much in couple weeks from my SS2 but I've opened the manifold up a fair bit plus heaps of head work and cams. Will change manifold later if I have to but for now just want it back together

[hypergear]

E85 will solve most of the problems. How ever its not very available at this stage.

I'm also updating the SS2's profile for better, more consistent power delivery and possibly even better response. Will have results in roughly 2 weeks time or when Trent's dyno is repaired.

[Hanaldo]

*Should* have a result with my new setup tomorrow. Car is fixed and running perfectly now, will hit the dyno tomorrow. So providing nothing else goes wrong, will finally have a result.
