Hypergear Turbochargers and High flow Services Development thread

[zebra]

Any more progress on 1j highflows (ct12a) or not enough demand?

[hypergear]

Standard CT12a high flows are same as usual using ATR28G1 chras. I can also run the SS1 CHRAs for better performance.

Thanks.

Will keep an eye out

Stao quick question. Its really pointless but thought I'd ask.

The green XR6T known as toxic has a bent exhaust wheel fin. It produces a sound like a supercharger.

Video here.

Guy claims it doesn't affect performance. Can you do this on one of your turbo's and achieve this sound or was his by sheer luck lol. I don't care what anyone says but it sounds awesome.

[34GeeTeeTee]

The guy clearly did that on a private road or track

LoL no. I would pull it part and replace the exhaust wheel. Unfortunately Garrett no long sale rebuilding parts for their own turbos, so it needs to be fully overhauled. I would not buy that car the way it is.

Some news for SR20det lovers

This is the latest ATR28SS1.5 It is engineered to peek 260rwkws on pump 98 with supporting mods while has a stock T28's response.

There are private roads like that. I know magazines use them for photo shoots etc. ...

Cool!!

Any dyno graphs?

For a fairly stock setup, when does full boost come on with this turbo?

[hypergear]

Currently only have results from it on a Rb25det with larger turbine housing. That made 298rwkws on 21psi with full boost by 3600RPMs.

SR20det using a smaller .64 rear should behave very similarly. But no SR20det result on this turbocharger so far. This customer should have a result for me very soon.

Took a photo of when my SS1PU makes full boost the other night.

21psi by 3400rpm

Hi Stao,

That sounds fantastic!

So what would it take to convert my ss1pu to this badboy?

[hypergear]

This is a smaller turbocharger then the SS1PU. Cost to convert SS1PU to SS1.5 is $150.

[MoJizzy]

Bargain!

So let me get this straight. Its smaller than the the ss1pu, makes more power and is more responsive on an SR20

Have i understood this correct?

Cheers

Hey Morgan,

It's smaller than the SS1PU and will make less power in total. Stao is referring to his E85 results, where his SS1PU E85 result was over 320kw IIRC.

I have forgotten to PM you in some time so are due for a catch PM me if you need me to clarify.

[hy_rpm]

500rpm sppol difference is worth 10-20kw less in outright power

Depends how you like it to drive

Most street driven cars are always below 5000rpm most of the time

[hy_rpm]

Spewing should have got the upgrade done to mine when he had it to change the rear housing

I'm going to head out to Sunday street meet at wsid next week hopefully get 11s now as I got et streets

Hey Man hows it been?

I'm a little confused bro, stao's post above states 260rwkw on 98 not e85. I want as much response as possible and it seems that the ss1.5 will deliver the same power earlier on than the ss1pu but the ss1pu will make more up top.

[GTScotT]

Sorry, I saw his response of 298 which is E85, missed the 260kw bit.

Remember these figures are based on his testing with the RB25, so while he knows it will have about 260kw worth of flow on 98 that is also compared to the SS1PU having nearly 280 worth of flow on 98.

Stao are the smaller SS wheels still based on the original high/low blade design or are all SS turbos now using the same straight blade design as the SS2?
