Hypergear Turbochargers and High flow Services Development thread

Video footage of last weeks South Australia Time attack. Our sponsored vehicle is Topstage's carbon S14. 2015 built ceramic ball bearing ATR45SAT turbocharger survived engine failures, melted exhaust manifold, and this time fire from hydraulics fluid leakage.  Still managed to take first in rear wheel drive class.

Product update for ATR43 RB bolt on series with 3 inches dump pipe suited for Rb25det and Rb30ET.

Available using ATR / SS series as well as Garrett GT / GTX CHRA. 

Housing's available in T3 .63 and .82, internal gated with 38mm port. Externally gated housings can also be supplied. More details are on our site, or simply send us a PM.

Little video to share about Jason Ferron's drifting session at Calder park few weeks ago. Video's been put together by the Drift Junkie Andrew Sparrow, do check out their Youtube channels about he's R33 GTST build.

Jasons's car is powered by one of our high flowed R33 GTST turbochargers making around 310rwkws on E85 fuel.

Another 400rwkws Rb25det powered by one of our ATR45SAT turbochargers, externally gated E85 fuel. Tuned by JEM.

that's pure turbo-porn right there.

Got my car tuned finally by DVS JEZ after having some issues with "less competent" tuners in Canberra.  I know my setup is not ideal (return-flow) but was hesitant to spend money on restrictive parts if i needed to spend money first on fundamental running issues. 

 

Setup is as follows:

R32 Nistune ECU

EFI solutions Top fuel rail kit,  stock FPR with Bosch 0 280 157 187 495cc Injectors

Bosch Z32 AFM

3" Turbo back (bellmouth, port matched) 3" 100 cel 4" body Venom cat, straight through mufflers

Hypergear G2 21U Highflow

Greddy Profec OLED EBC

Custom Hard 3" intake pipe joining to stock Airbox, Return Bov

Return flow AVO Turboworld intercooler

R32 10psi actuator pre-loaded 3mm

GTR BOV

NPC clutch

SPlitfire coilpacks

Standard Walbro 255 with the wiring mod. 

 

Overall result is pretty good but quoted from Jez couldn't get more out of it "too prone to detonation", note the 230kw run was abandoned. so running 223Kw on 16psi

 

Now i know its running right i am looking to buy a new intercooler either HDI or Plazmaman and the 5" body 100cel 3" cat and then getting the tune tidied up a bit. 

 

My initial goal was to make the most responsive setup compared to stock turbo running 98 and airbox (hate the sound of pod filter) hence g2 profile choice. Can see my old tune in second pic of stock turbo and breathing mods.

 

Tao what do you think of the result? Besides changing the above (intercooler and cat)  and staying on 98 and an airbox (happy to modify it), is there anything else i can do to increase response/boost response.

 

Kind regards

Patrick

Charge temps are too high, your cat is fine.

Yeah right. Well the plazmaman street series is a bar and played and the hdi is tube and fin. 

Those are the two I'm looking at at this point as reasonable options

Don't bother with the Plazmaman Street Series, they're as good as a HDi.

Get the HDi GT2 coolers, they're pretty decent for the money you're paying, yes return flows "make" power on E85 setups, because that fuel suppresses so much knock it doesn't matter how hot your charge temps (IATs) are.

Cooler air = Denser Air = Less knock

Time to cut a hole in your body work

The car needs a big front mount cooler,  Go for Aero flow 600x300x100mm for a good budget cooler. Also the G2 model is a factory replacement, to get more power you will need the G3 or bigger profiles.

Hi Tao, 

Thanks for the response.

when I was first bought the turbo you mentioned with the right supporting mods it could make 250kw.

Reason for going g2 was wanting as close as possible to factory response as per your results below, where I seem to be making similar power but at 16-18psi instead of 13.

Did you manage to achieve above 230 with this turbo?

Guess I want to see if it's worth my while changing cooler and get the tune tidyed up a bit and try make close to 250.

 

Kind regards

Patrick

The highest result out of the G2 profile lot was from Dr.Drift's personal R33 back in 2010. That pulled 253rwkws on pump 98 fuel.

Sent you a pm ?

@Pattey21 hub dyno vs. roller dyno - results will vary.

[lexxi32]

[mention=88652]Pattey21[/mention] hub dyno vs. roller dyno - results will vary.

Not if there calibrated properly.

[Pattey21]

Had a chat with Dr Drift. His had a ext gate and adj cam gears. He did have a return flow though.

Sent Tao a message about upgrading to a g3 with BB

If they're calibrated properly a roller will read lower due to the energy loss via the roller/wheel contact.

Also different tyres provide different readings, you run say semi slicks on a dyno make x kWs and the next day run just normal street tyres and you'll end up with a higher reading of y kWs.

Tao, the new 21u basic high flow that made 342rwkw with the free flowing turbine wheel, is that as responsive as the earlier version? 

How does boost response compare to the stock turbo?  Yours isn’t ball bearing so is it slightly laggier? 

I have a 2860 (similar to hks2530) on the rb25 and don’t want to lose that response.. 

 

thanks

 

[hypergear]

It will definitely not be as responsive as a 2860. That is too small for a rb25det. 

New G3 high flow has the same response as the older version with more mod range and top end power. It is still very responsive for daily or track.

[benl1981]

Thanks Tao, 

So a g3 high flow should get about 260rwkw on an r33 p98, as opposed to a 2860 around 220-230 do you think? 

How much difference in boost response? I’m getting about 9psi by about 2300rpm in 4th I think..
