Hypergear Turbochargers and High flow Services Development thread

[Missileman]

I'll try one when I get rid of my rb20

Just got back from the gold coast where I drove a stock HCR32 kouki in Dark Blue Pearl with the dark chrome grill garnish, very pretty car.

Hey Tao, What would you recomend for a VH45DE engine? pref in single config. Street driven so reasonable response around 400rwkw minimum range?

[Lethal26]

hey, I have 34 gtt 25neo!! Chasing around 350rwkw with a good response, which turbo you would recommend?

So far I got

Fmic

3inch tbe

Nistune with flex tune 98/85

Hpx afm in a 3inch pipe

Walbro 460

1000cc injectors

Avcr boost controller

Cheers

You are on page 577 of this thread. You don't think perhaps that you answer might already be here?

[Lethal26]

Will look into it thanks

350rwkws on E85 fuel you can use our new ATR43G3SAT model. You will need a very big exhaust and a very free flow cooler to run ATR45SAT, that can get close to 350rwkws on P98 fuel.

[Trex]

Hey Tao. Have you posted P98 power figures of your new 21U turbo? If not could you please?

I'd imagine the OP housing would make minimal gains over the 21U?

What size is your exhaust and what mufflers etc?

[hypergear]

The best I've got was 287rwkws P98 fuel on 21psi. R34 GTT Neo engine. with Exhaust Tee and PWR cooler:

[hypergear]

Our high flowed T517Z. 507awkws @ 22psi E85 fuel internally gated, on a built RB26dett by Forged Performance in SA. Looking at stiffer actuators and run up to 30psi. Hopefully be seeing 600awkws.

How is the exhaust T going after all this time? I was a bit skeptical of the spring loosening up over time and when the exhaust gets hot.

^ you're better off using an external gate with a weak spring to emulate what Tao is doing with that flapper. A few guys have done that (not here) but Google!

I wouldn't be doing the mod just curious as to how it's held up over time as it's different than the ex and int types.

I know a few people who have tried this with external and internal gate mechanisms, but they have all had problems.

[hypergear]

Well, the exhaust Tee is bleeding with not as compressed air as what it is inside the exhaust manifold. So it needs to be alot bigger. There are many ways of doing it, the most popular I've seen was that window switch motor controlled valve on ebay. That doesn't work very well as the motor gets overheated by exhaust gas.

Alternatively you can use an actuator to control the valve, which is very reliable, or just some good high tensile springs. Its a simple device, but that definitely shown an improvement.

For this engine you can run one of our ATR45 in a 1.06 rear housing externally gated. On E85 fuel that will be plenty for 400rwkws

Also vid sent in from Jason using one of our prototype ATR43 in his 1JZ, the goal was a responsive 300rwkws on Pump fuel with out VVTI. It is not an easy task as I originally predicted, project is still on going.

Vid shown 320rwkws on E85 fuel @ 22psi

Hey tao im looking at getting my turbo high flowed for my stagea its the rb25det whats the best 1 to get the 0p6 rear housing or the other.

[hypergear]

The the heavier stagea, the op6 is recommend over the 21U.

[Griffin]

Are you able to rebuild / hiflow a ford fg xr6 turbo? It's bearings are shot, compressor has hit the housing.

[hypergear]

Yes. Rebuild Using using a bush bearing core will cost u 700 or a Garrett bb core for 1050. Will require braided oil line and mico filter removed for either cores

[Griffin]

OK thanks, will there be much difference in performance over standard?

[stagnutz]

Ok and what suporting mods are required i have fmi 3"dump exhust can this turbo b utilised without a tune can you set boost to afr's ratio

[Ben C34]

Wut?

Not tune, set boost to afr? What you mean man?
