Hypergear Turbochargers and High flow Services Development thread

Sorry I can't remember exactly. That should be the SAT model. Externally gated?

Internal.

I thought you were going to send me the SAT version but don't actually know the difference.

[hypergear]

Please email me a photo of the rear turbine and comp of the turbo. I don't remember building internally gated SAT versions for any one. if it is the SAT model, it might be running 22psi minimum boost, but I can make changes to it if not yet installed.

1JZ none VVTI using our ATR45SAT prototype making super responsive 338rwkws @19 psi externally gated.

Drift footage from last weekend.

Interesting re. The intercooler studies.

I'm considering a r34 blitz return flow on an r34gtt to be used in conjunction with a high flow to make around 250rwkw. Are these worth it? or will the generate alot more lag/loss of response? Would prefer not to cut a hole..

[hypergear]

Consider PWR 600x300x81mm FMIC instead. The Blitz return flow did not work for me.

If you really have to use the Blitz return flow and make power. get our ATR45-SRFC special application turbo. I can pump get that to make close to 300rwkws on that cooler kit.

[benl1981]

For 250rwkw with your standard 21 u highflow on an r34 would the blitz be ok? And not compromise response too much?

I note your point for if aiming high then pwr intercooler is a must.

[hypergear]

It should be maxing out towards 250rwkws region.

[benl1981]

So response wise up to 250rwkw not too much difference?

[hypergear]

There was a difference shown on the dyno. But for turbo in that size it won't make any differences to drive ability.

Out of curiosity which Blitz return flow are you using as there were two sizes of the long lower pipe . Mine I believe is the earlier version with the larger diameter lower one . It may not make much difference but occasionally things like this can .

Well after 3 years I've finally got interested again at fixing the issues with my ss2 setup.

Since last time it's got a new exhaust, cams both dialled which resulted in them getting advanced and water meth kit finished off. Unfortunately similar results to last time anymore than 18 psi it started missing and seemed like a failed coil pack as changing plugs didn't help. I got into some testing and noticed my speed signal is erratic with about a 10:1 noise. At 800rpm it fluctuates 80, 300rpm changes while cruising at 3k on highway and map tracer is constantly bouncing left right.

I'll get a new Cas and double check for intake leaks etc then try again for a better result. It's currently running about 11 degrees at peak torque and increases to 15

Just got this today.

Haven't got digital copy of this yet, only photo

Ive finally got my 25 back in the 31 with the atr43ss2, going to be getting a flex tune done shortly so will update what it does.

Tao what turbo do you have for a SOHC rb30? Mates after something quite large. Does the ATR45 come in a trim suitable for a 3litre?

[hypergear]

Yes I can make an ATR45 that is bolt on to RB30et's manifold front pipe and all lines.

If you using a 0p6/vl turbo/ 300zx etc etc .63 rear, id be getting a atr45 SAT for a Rb30..as the .63s with 3582/atr45 rear turbine wheels choke the f**k out of them..to much backpressure

Rb30 sohc motors like .82 housings with those atr45/3582 turbines..

The one in photo above is .82 internally gated.

[AUSBen31T]

Yeah his after external gate version, going to put gate off housing, whats the price for the external gate version?

[Daz]

These walbro e85 pumps having issues?

[hypergear]

For externally gated if he still wants that dump pipe to be made it will still be $1250, How ever if he's happy to make his own dump pipe it will cost $950

[RIPS_R33]

Hey hypergear. Just wondering if you have any r33 high flow turbos on the shelf for exchange. Or do you only build them once receiving them from the customer.

Thanks mate

Very good ! You will also need a small/medium camshaft (220-230 @.50 duration, upper 400 thou lift, 115-117 lsa ) depending on car use and trans and a set of valve springs

on a on a sohc rb30 to make power with that turbo..

cheers
