Hypergear Turbochargers and High flow Services Development thread

[hypergear]

You get full boost by 4300RPMs with RB25det using .82. It pulls lot harder.

If your purposes of buying this turbo is for mild power street use the .63 is fine, But it does get really hot under high boost if you use it for drifting or tracking.

Another small update:

Still remember this ATR43G3 unit with .82 turbine and .70 comp?

Got it dyno tuned today, car mad 298.5rwkws on 21psi with miss-fire. Only done 2 runs, car miss-fired very bad after, we changed plugs cleaned coils and nothing helped. I will give another try with splitfire coils in few weeks. I didn't grab the dynosheet this time. But dyno footage with 3 people in the boot is worth to look at:

(click on photo below to watch that video footage)

Also my engine comp shown:

130, 125, 125, 120, 125, 119

Next run will be with a new forged engine

[geraus]

Niceeeeee

[SimonR32]

I'd say the miss might be due to shit compression haha

When you getting 15psi with that turbo?

[raZ1911]

Nice, when's full boost?

[hypergear]

I had 21psi by 4100RPM. its drives very nice and pulls hard on the road.

nice power how much for the turbo? and what mods does it require to bolt up

[hypergear]

Installation information with photos are in page 39. cheers.

[paulr33]

what does it rev out to? if it has 21psi at 4100rpm and peak power is at 5300rpm what is max rpm ?

[hypergear]

Peak power was around 7000RPM. Check the 2nd run with people in the boot.

Power rise till red line, the curve is very similar to the 268rwkws run with restrictive intake and the 316rwkws run on with the sil180.

car was not strapped with wheel spin, Reved to 7000RPM as usual.

These are the ones i wanna see more of 0.82 has a better power torque balance than 0.63.

[Crans]

I think this turbo is the same as my ATR28g4. Getting slightly better spool now with my alternator changed. Hitting 1 bar just after 4000rpm with no boost controller. 10psi Actuator with heap of preload

[R32 Driver]

with an OP6 Hi-Flow on a RB20

whats the most boost/HP it will make?

[hypergear]

I haven't had any customers using OP6 high flows on RB20det yet so I can't give you an exact figure. I would say roughly 230rwkws.

Further updates:

Apart from turbochargers our engineers are also dedicated in to engine building, how ever I'll not provide this service to the public. I will show every one how it’s done and costs involved. Any useful advise is welcomed.

Primary goal:

This engine will be used for our turbocharger evaluation pusposes, My goal is 350rwkws.

This engine will be built with stock cams using forged pistons only, so Power vs Boost generated from it would be identical to any other healthy standard RB25dets.

Engine:

96 model RB25det engine bought from local wrecker.

An hour later its in bits:

Cracked piston in cyc 6. But bore seems to be in ok condition

I’ll be using forged CP 20 thou over sized RB25det pistons with rings and pins. The piston set cost $1150 AUD.

[boostn0199]

Good work, will be great to see the results now with you being able to run 20+ psi,.

[hypergear]

Engine block's been sent away to Reflex engine services. Its going to cost $260 to re-bore all 6 cyc with block thermo bathed. Engine head cost $250 to trim and bath.

Also for people whom owns a pair of CT12a Powered 1JZ Soarers. We can high flow them to 2860rs Disco CHRA specifications in sleeve bearing:

[zebra]

Looks good stao,

Whats the cost? If my stockies let go id be up for a set.

[Birds]

Yeah also curious about the C12s re:cost.

[hypergear]

They will be $950 per turbo. Need about a 4 days to get both done. Huge amount of engineering work involved, very time consuming.
