Hypergear Turbochargers and High flow Services Development thread

I think that would an excellent turbo for the FJ20, you will want to run that in a ball bearing core for this application. 

[jet_r31]

Can you put up a dyno graph with a overlay of the  new tall ss2  comp vs older shorter ss2?, to see where the gains are

 and maybe the g3 sat result your chasing out of interest?

cheers

Naa the G3SAT killed it in both power and response. I'm not been able to make anything thats more responsive at its HP.

 

And some video footages from this week:

HyperGears ATR45SAT Ceramic ball bearing turbocharger powered Team Lori Blue Bird. Sandown race track 1.24 run before WTAC. Car is a 4WD, has SR20VET engine, Built gear box, Fuel and injector mores, manifold and external gate. Tuned at Springymotors made 340awkws E85 fuel. Car driven by John Reco

The latest Upgrade in Rb25det Bolton turbo upgrade. 

 

 

Had my R34 on dyno today testing the latest ATR45SAT ceramic ball bearing turbo. Amazingly it made the same power with 250RPM better in response. Plus most importantly, this turbocharger is happy to run a minimum boost level of 20psi, which the older model can run no less then 22psi. P98 fuel

Now hitting 20psi @ 3650RPM vs Older version of 14psi @ 3650RPM. Car made a peek of 331rwkws and average of 325rwkws @ 22psi with 3 inches turbo back exhaust + Tee connected, It is a blast to drive.

Recap, Car has:

R34 GTT RB25DET NEO unopened engine.
- Adaptronic� ECU
- 1000CC ID injectors
- Factory cams, cams gears, and all manifolds.
- HyperGear ATR45SAT (Pro-B 150816) Ceramic Ball bearing Internal gated RB25 bolton Turbocharger
- JJR 3 inches turbo back exhaust, 2 inches Tee from front pipe.
- Walbro 470L/H Fuel pump
- 4 inches induction pipe
- Split fire coil packs
- PWR 600x300x81mm intercooler
-Tuned by Chequered Tuning Melbourne (Highly recommended)\

Which one was the one I purchased, a few weeks back?  

[hypergear]

That will be the RV-1, which is still pretty good.

 

[Manuel Kasko]

Aww damn! 
Is this one being compared to the Rv-1 in the above dyno sheet? 

[discopotato03]

Just curious , is this running a GT30 IW style turbine housing ?

Cheers  Adrian .

[hypergear]

No, its running a 6 bolt Nissan bolton type of a housing connected to a JJR 6 bolt dump.

Here is one more result that are worth posting.

This is from one of my troubled customers whom like many others using stealth setups including a return flow cooler and a silent exhaust. Obviously it made a petty 260rwkws P98 using our ATR43SS2 turbocharger with a massive boost drop. The SS2 however have held a dead flat 20psi on my R33 peeking 302rwkws. Fixing that boost drop problem, he went all the troubles fitting up an External gate that made only a 5kws gain. His disappointment anger and frustration has been directed to the turbo and my self.   

During that time, initial ATR45SAT was first made and tested by Havoc Fabrications at 420rwkws. An upgrade request was made by the customer so the same turbo was built and sent for the exchange of the ATR43SS2 which I'm yet to receive. With nothing else apart from the turbo change and E85, the car made an disappointing 354rwkws, that have sparked more heated conversations, to prove my product I have later managed to use the same turbo beating his E85 result running internal gate on less boost.

Red- My internally gated result vs Blue - under performing externally gated result

 

Finding out reasons and answers in solving those issues, I have bought my 2nd and 3rd R34, picked the exact same mods used, guess what I ended up with same crappy result. Investigation pointed to the Blitz return flow cooler, the 2.5 inches resonator inside Jap exhausts as well as the EPA approved compliance cat, test results of those are documented in my earlier updates of this thread.

 

A proper front mount cooler is finally fitted, with a good cold air induction system and a free flow exhaust installed. using the same turbocharger the car has now hit 400rwkws on E85 fuel:

Vs controlled result:

 

 

This is an perfect example of how important it is picking the right supporting and differences it makes to overall performance.

What is that airbox for the 34?

Setup always matters for results. I actually just found myself how much restriction the airbox can be at 400+. Though, my blitz fmic is still going strong.

What was the difference Greg?
At my peasant power level the car only picked up another 10rwkw with the airbox lid and filter removed, same as a fluffy dice or a JDM sticker basically.

One of the bigger differences in my setup was going from an X-Force cat to Venom 100cpi, that was significant.

Also Tao in the photo above is that a boxed pod setup under that stealth lid?

[Kinkstaah]

For me it was 45kw lol. But my lid had no modifications and the difference was lid off/on back to back.

My VCT was also not working, so fixing that got power on 800rpm earlier.

So it pays to test all setups!

I have made a solution to get mine going that looks stocker than that box, but still curious to know what it was.

I was lucky that the seat of the pants feel was massively different (and so was boost) so it was very obvious for me to test my 'fix'

Also worth noting I am auto. So if you make about 400 on a manual the lid will work. I was making about 365kw with the lid on and 410 with it off and the car decided to just run 28psi instead of 21. The restriction was real.

That said it's still fine in my experience for any turbo on a 25 that wouldn't be too laggy to actually want.

Any update on the ss2 with the .60 front housing?

[hypergear]

It didn't work out as good as the G3SAT model. So for the best response 250~300rwkws application use that instead.

 

[iruvyouskyrine]

can you convert standard RB20 turbo to steel wheel (or billet or whatever) and ball bearing?

[hypergear]

Yes can be done. That will be our G2 high flow with bb upgrade.

[iruvyouskyrine]

Have you got a link, i cant seem to find that turbo anywhere on your website? 

Thanks

[hypergear]

click on the G2 profile, and click on the ball bearing upgrade. Also when submitting the order, please add note state its for an Rb20det engine. 

[iruvyouskyrine]

what is the max boost this turbo could run? thinking 25+ psi
