Hypergear Turbochargers and High flow Services Development thread

Teaser video of my car running again:

Mate was driving and was too nervous to drive it hard, so when I can drive again I'll get some better footage.

Can't watch the video brah

That's an impressive result, Stao. Really holds on up top now. Defo worth the effort of dual actuators IMO.

It made barely any difference Aaron, the dyno result was from two different AR rear housings if I read it right.

Stao, were they 20psi actuators?

We are talking about 1.2psi gain, not a mojor but there is a difference, notice the shape of the curve too. The 20psi actuator still had 3psi drop. this sheet was taken when using the same turbine housing

compare to:

The SS1PU probably had the most boost drop internally gated, this actuator setup should work well with that.

Do you bore out the wastegate hole Stao?

Maybe you could look at the EFR turbos and borrow some ideas from them to come up with a better rear housing design?

[scotty nm35]

The SS1PU due to the higher pressure in the exhaust manifold, too much pressure here would cause heat issues though, you need an exhaust temp sensor in the manifold imo Stao.

Have you incorperated the longer actuator arm for more leverage also?

Ahh crap, I missed that the bottom graph was the two different rears.

[Hanaldo]

Video should be public now guys, sorry about that.

Please refer to post 6125. They are identical turbochargers, both with .82 type B rear housings just different actuator setup.

Talk about great service!

I ordered my turbo on Monday, it was built and is already in the post. Stao has still been answering my queries and testing products in between, now that's what I call great service

[t_revz]

Different arm to mine but looks to be similar length so should have same leverage

Stao mine has the longer arm and I lose 2psi up top. Is it worth loosening the screws and extending it out to the edge of have you tried that and made little difference?

sounds siiick. was that on gnangara rd?

[Hanaldo]

Yep!

[GTScotT]

Lol sounds hot Martin, love it.

[jay-rod]

Tune done.

340HP ATW (338 to be exact!)

I like it alot!!

Thanks Stao drives like a freight train.

Will post dyno up soon

[blah_blah]

Isn't yours a 300rwkw turbo Jared?

Limited by something?

[jay-rod]

My rear exhaust and Cat i believe

[Hanaldo]

Yay for restrictions!

[jay-rod]

What did you get martin?

edit, i thought u fixed the restriction.

Speaking of restrictions...both my cams look a couple degrees retarded. Might have to grab an adjustable gear for exhaust cam. Obviously need to put a dial gauge on and check for sure but if I see cheap cam gears in Japan next week ill be all over em
