Hypergear Turbochargers and High flow Services Development thread

Also I am very interested stao. Are you just taking about slotting it like an anti-surge front housing? And how much lag are we talking?

nek minite

22s on a 33 to go with sik spool noises

[hypergear]

Yes that would be the anti surge slots that are plug able if you don't like the sound or lag. usually be seeing 300RPM of differences in lag.

also keen to see how an ss2 made to sound like a t51r coming onto boost goes.. could consider getting it done to mine i could deal with the extra lag... man that things just pure ear porn!

[zebra]

you guys realize that a T51R sounds the way it does because....

well its a T51R and not an ss2

maybe tao can build you an exact replica and you can have gay as rainbow noises

Perfect. Even keep your 300 rpm worth of response.

[Artic Choc]

hahahaha ^^ nice! yeah i am aware that is why, but hey theyr way to laggy for a 25 so no chance il be getting one anytime soon

If you actually read my initial post my question was why does it sound the way it does. I asked as I thought that stao would know seeing as he builds turbos for a living.

Also it's beyond me how anyone can not love that sound haha. If I can use my SS2 (which I love) and also get it to sound more aggressive then what's the issue? As stao said I'm running an RB30 bottom end with what most people would consider and undersized turbo, and I don't really give a f**k about extra lag (within reason)

Please understand that different people enjoy different things and not everyone has to share your viewpoint

I want anti surge characteristics, which in turns gives you that awesome noise

[methz]

Surge front cover won't ever sound like a 51r, there is a reason ppl pay 4k for one of them.

[jjman]

"that sound' is always going to sound bigger and better on a bigger and better turbo for sure.

The HKS 3037 Pro also makes that sound but in a less powerful way than the T51R because, well, it is a less powerful turbo.

If you get the surge slots in your turbo it will probably be like this. Decent and what you are after, but it is never going to have that 'end of days' sound like a T51R spooling up.

eg this vs this

^^ I read on there facebook page that it made the same power on same boost as a t67 high mount ex gate setup on e85 they did not long ago

cheers

I'll try and find a video of my HKS GT2835KAI, it had a surge slotted front cover and whistled like crazy without ever going terribly fast. Would even whistle going around car parks. Sounded pretty cool, just a shame it never lived up to the old Pro S

The KAI had a removable 'snout' with the surge slots, I ended up getting another one made without the surge slots to see if it improved anything, think it may have improved torque slightly, noise was still there because the bolt holes for the snout were still in the front of the snout, had just lost the surge slots between them. Odd little turbo that one. They should have stuck with the Pro S

Some photos of a pair of our high flowed Greedy T517Z in 10cm Rear for a GTR. Now fitted with our SL20.5 CHRAs and enlarged 36mm internal wastegate. They should be now good enough to reach 500rwkws+. Will update results once tuned.

[Piggaz]

Any test dummies yet?

[XKLABA]

I'll test em, I'm a dummy

[Aggroman]

looks like just what you were after there Mick!!

[XKLABA]

Comp wheel is a bit bigger then what I am looking for ( 74mm v 68mm ) but yeah close enough

[hypergear]

SS15 is in 68mm. For those high flows, one of them would be good enough for 380rwkws on a Rb25det externally gated E85. They would be similar to having two TD06L2-20Gs with alot more power.
