ASked Stao about a bush bearing hi flow with 360 washers...$960

Asked him about getting a 3071 core and this is what he said:

Well, there is no point going for 3071 CHRA in your high flow as the rear housing of it is already small and our customized will produce more power then the 3071 profile. There will be no difference in response based on factory housings, plus bush bearing is a more relaible setup then the ball bearing setup. The 3071 high flow cost $1550 AUD, you need to change all water, and oil lines to suit that CHRA.

The factory housing is not big enough to flow 350rwkws. The max we can that that to is 300rwkws on a manual, Auto will be about 25KW behind plus it won't handle any thing relaiably above 230rwkws. I would recommend you to use our standard high flow option with a high pressure actuator to achieve that goal.

Regards

Stao

hmmm stick with bush bearing i guess?

Who was asking for 350awkw on a highflow? lol.

Stao has only seen the rear housing once? So he doesn't have any data anyway as to the AR and flow of the rear housing. Craig has already proven them to 270 with the 3071, on 15 psi wasnt it? Perhaps 25 psi on ethanol may get you to 350? If you push it...

.....If i'm at 270AWKW's at 15psi on BP and the only reason we didn't push it to 300AWKW's was the GB(correct me if I'm wrong Scott) was just about to shit it's self.....then 340AWKW's on E85 is more than capable of happening with 30/71 Garret BB set....going buy what he things is the RW to AW difference is add 25KW's(his figure....mines closer to 40kw's) to that.......

and yes there is a bit to change to get a Garrett setup working......but I would not say a lot!

Comes to how much you want to develop......If I had my time again I would still go for a Garrett BB set....I might have gone a little smaller though!...maybeninja.gif

P.S. I am not saying bush is shit......but I am not willing to accept that a proper BB setup is not as reliable either when done properly!

and what Scott said he answer at the same time!...lol

Go the BB f you want. Hypergear actually do high flow with a BB core properly.

What Stao is referencing there with his power figures is the RB25det.

As you can see from other members experiences, this is not relevant to the VQ25det.

hmm ok...

in all seriousness though if I get 220-240 awkw I'd be happy. Anything more means gearbox needs to be rebuilt and I'm not ready $$ wise for that. Neither is manual conversion...

The potential to go 300awkw with the bush is there....I might just go with that and IF I have the $$ for a gearbox rebuild later on we can always up the psi then to hit higher power...

Can someone let me know any specs or size that I need to tell Stao for the hi flow?

what are you running scotty ? and how does it perform any cons?

And never will be relevant, we have much thinner castings on the rear so even though it looks small, the nossle is actually bigger than a op7 rear on the 34's.

I have a stage one sierra bush highflow, makes positive boost at just over 2k. With an auto you dont want to go too big as the stall converter would have to be opened up to compensate for the lag. Mine seems almost perfect as the 3k stall gets me up into full boost (20psi) almost straight away. Aaron's is much less responsive.

what do you mean by sierra stage 1,2 highflow ??

so your happy with what your gains are without trans mods etc?

how much

He will be pushing for a 3076, but if you are happy with 220-240, just go the 3071 core.

Then get a G-zone to piggyback your eManage onto (removes the throttle restriction and speed limiter)

Hmm see Stao's response when I asked him about the 3071 core - he pretty much said no?

I want what scott's got...:teehee:

The go spend extra money with Kyp.

Then get your car on an ethanol blend.

Simple really.

Kyp also said "no" to the other highflow spec that I gave him, but he did it anyway and the owner was very happy with the result.

Its like spitting in their face. lol. They are turbo builders not housing machinists. They will never WANT to do a Garrett core. :laugh:

I meant his hiflow SIZE and specs, not his power output....grrrr

We've have archived 305rwkws with Our customized wheel combination (PU profile) based on 98 fuel which would be around 350rwkws on E85. With aftermarket comp housing we've managed to reach 345rwkws on 98 fuel which should be around 400rwkws on E85. There still are people using sierra wheels, how ever to us that is part of the history.

What's PU profile?

The standard we use is in either 71mm 52T, 56T, 76mm 52T, 56T, 58T.

Depending on what power you are after. With the standard profile that we use is in 76mm 52T.

All we need to know is the HP / (rwkws) you want, leave the combination work to us.

Which one should I go for for max response?

As far as what I've learnt at Stao's workshop doing my high flow that he used to use the Sierra turbine wheel when he first started, then found its not been able to flow enough while creeping too much heat due to its blade design working with factory turbine housing, cropping it makes it super laggy.

He's made a special turbine wheel that is touch bit larger then Garrett GT30s with much larger exducer. Works out to be an 86T GT30 wheel. That made heaps more power while not adding any much more lag. Going by his highflow thread you actually notice he's current high flows made heaps more power then what he originally started.

On the comp wheel side they have customized wheels with skinny hub and large blades so in theroy they would flow lot more then what standard Garrett comp wheel would based in the same size and trim.

I generally would not be comparing them to other high flows using Garrett along parts. The best way would be tell him what HP you want and let them do the thinking.

I could listen to all this talk of turbo matching all day, the bloody things fascinate me. I almost WANT mine to fail so I can join the fun...

Almost...whistling.gif

In that case just turn your boost up to 20 psi for a win/win situation!

      Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.
