Hypergear Turbochargers and High flow Services Development thread

[Manuel Kasko]

Those figures you are talking about stao is that with E85 or 98?

My plan is e85 and 300rwkw so more response the better. I'm guess that would be the 260rwkw one you are taking about?

[hypergear]

Those are all E85 figures. that would be roughly 260rwkws on P98 fuel.

Massive thanks to Hypergear to assisting me with my turbo issues and rebuilding my 35R to ATR43 specs. I cant wait to drive the car with this!

[methz]

did u figure out why u killed it in the first place? looks the goods

[Simon-S14]

bearings failed on the garrett

I'm going to assume its gone to SS3 specs? Should have tried his fancy VNT setup.

[Blackkers]

how well does the VNT setup work?

[hypergear]

That above is a ATR43SSG4 core, so similar what it originally was.

The VNT system do work and I've been using them a while now for anti lag. This specific method has the potential to knock off about 500RPMs of lag without trading off power. How ever has to be very specific to the amount of back pressure the turbine housing is receiving. Little like setting up Ign timing which at specific point they will allow the engine to output its highest torque while otherwise results the opposite. Some thing worked so well on the RB25det worked horribly on the Kia's High comp G4GC motor. So getting this to work on the Rb30det it will require a new round of research and development.

Posting an result. This is from a SS2 Based High flow that we did for a Auto M35 stagea not too long ago. It made 275rwkws on 20psi with Pump 98 fuel.

Note: The WOT was engaged in a slow manner on run below, for the reliability of factory Auto.

My SLSS2 turned up today

Looks good sitting next to my old highflow paperweight

That pic raises another question Tao , is the compressor housing on your turbo a 0.70 AR T04B one ? The larger ratio B housing is one we don't see too often though I don't know why . It would have a bit more flow capacity than the 0.60AR B housing while being more compact than the T04E or T04S ones .

0.70AR B housings have larger 2.5" (63mm) outlets like 0.70 AR S ones .

A .

[hypergear]

The discharge temp using this comp housing is lower. Helps top end by a little.

[hypergear]

And any one into Nissan patrol 4.2L Diesels ? High flowed stock turbo made 121awkws on 15psi maxing out stock fuel pump. Stock turbocharger maxed at 81awkws.

WTF happened to that compressor wheel? What highflow was that?

It is a Kinugawa highflow. The oil feed line let go while coming onto the highway in second at high revs.

It looks right at home

Hoookay

Some initial feedback on the TD06SL220.5G

My car is hardly sorted atm

but is as follows

Dead Standard 1JZ-GTE and Auto

ETM 6 into 1 merge collector manifold

Hypergear 50mm External gate

3" dump pipe into a 2 1/4" mid pipe into a 2 1/4" twin system (yuck!)

factory ECU

So initial drive

Builds boost at around the same RPM as the standard turbos...but feels like it needs a little more throttle to do so

Once it sees around 0.2bar and 3000ish rpm it comes on like a light switch even at under half throttle (no WOT runs re: standard ECU) running the 0.8Bar gate pressure

This combo is going to have a monster mid range once I finish the new exhaust (3.5" with a Hooker super comp aero chamber muffler) and fit the ECU and fuel system

but I feel it is not going to be linear, feels like it will always be a light switch turbo, but comes on early enough to not be a huge worry, however I will report back once its tuned and I drive it in the wet.

Hey Kerrod, what exhaust manifold are you running with this setup?

thanks
