Hypergear Turbochargers and High flow Services Development thread


Recommended Posts

Straight up convert to top feed, use 1/2 height injectors that are stainless. The Bosch 1150cc (at 4 bar) are unmodified. Just don't use the bottom collar. These injectors are commonly referred to as Seadoo Injectors. At 3bar they're 980cc.

Or get a set of Siemens DEKA V 80lb (~875cc) short stainless injectors and a normal top feed rail. All you need to do is trim the spacers to suit. Will fit snug underneath the stock plenum too and provide you years of endless joy.

My personal best was 320rwkws on E85 fuel. This car actually made more power. Looks like its got FFP, cooler and exhaust plus fuel and ecu. It might have cams as the power curve lookes like it has no active vct.

Are there any results for the ATR45SS on an RB? I'm tossing up between the ATR45 CBB and ATR45SS CBB. Tao what would be the expected difference in lag and power be between the two? Both external gate on a proper manifold on a 30DET.

Hi, Rb30det is different to Rb25det, its heaps more responsive. Both ATR45 and ATR45SS works fine depending on how much power u r chasing for. I've personally used an 700HP ATR45SAT in a 2JZGTE no VVTI, the end result would be very similar to a Rb30det.  Car made 406rwkws @ 20psi on P98 fuel, full boost by by 4000RPM.  So what sort of power r u chasing for and will the car be running on E85 or P98?

Hi Tao,

I should add I have an ATR45 CBB 0.82 on an RB30DET (different car and engine) and have been happy with it so I know what to expect from an ATR45, just curious what the difference would be with the billet compressor. Power goals are 450 give or take 20-30 so I know both turbos are in that ballpark. Will be flex tuned on E85 in a Stagea and keeping VCT.

For 450rwkws ATR45SS-1 with 63mm billet wheel will do. Next size can do 520rwkws+ on E85 they works extremely well with XR6 BA/FA, but would be considerably laggier working with a 3L.

Based on that would it be fair to expect that the SS-1 would give 20-30kw more than a normal ATR45 at the expense of 2-300rpm response? I'm just trying to figure out how it would compare to my other 30DET.

The ATR45SS-1 I'm pretty happy with and I would run that on Rb25det with a smaller rear end. when tested on the 2JZ, The response is almost identical to the normal ATR45  that made 30kws more. This particular comp wheel works with a normal ATR45 turbine.

Great result to share from Garage 7 tuned Rb25det Neo powered S14 running using one of our TD06SL205 turbochargers. This is an custom built turbo based in a TD06 rear end, externally gated.

Car has: 1000cc Injectors, Link ECU G4+ Storm Flex Fuel and usual supporting mods. 
Peek power made: 308rwkw on 98 and 378rwkw on E85.

Fabrications done by: Vulcan Performance and Fabrication

Dynoed and Tuned by: Garage 7

FFP modifications done by: NDR Fab Precision Race Fabrication

Sorry if a bit OT .

I was under the impression that this was a fail on RB25 plenums - or at least R33 spec ones .

Tao I'd like to hear your opinion on this one as I took your advice and fitted your preferred intercooler with a Just Jap over the fan pipe kit . It would be good to use a bend and throttle mounted on the plenum if it can be made to work properly .

Thanks in advance , cheers Adrian .

Plenty have done it and plenty say it's fine.  Many of those engines may have died, and you wouldn't hear about it if the plenum distribution was to blame because then the person who claimed it was fine would have proven themselves wrong.

But....I must stress, I don't know that it's not fine.  I only have very strong suspicion that it's not, because those plenums are not set up to receive air for all 6 cylinders from the front end.  The internal shapes are set up to receive it from the side.  I'm enough of an aerodynamicist to be very leery of that.  And I have never seen anyone report on 6x EGT probe results showing that it is fine.  On that basis, I simply wouldn't do it.  I'd be less worried about the various large plenums that bolt onto the bottom half, because at least they are simply big arse volumes on top of the runners, with no odd internal shapes to interfere.

Hi, the Car's running 22psi to produce results above. 

With that FFP modifications,  one of my tuners did mention it feeds CYC 5 and 6 more air then the rest causing them to run lean. I don't have personal experiences with them, so I can't comment.

    • Hi Guys, my car issues seem to be going from bad to worse and I’m hoping someone can offer some advice. I’m a Brit and have asked for help on the Brit forums but they’re not as active as they once were.    To save my thumbs I’m just going to copy and paste my posts from the Brit forum. I hope this isn’t considered lazy or rude:- 1st post…… For a while now my dash warning lights on my R34 GTT have been coming on. All of the them. When it happens the car runs like a bag of s**t. I pull over. Turn the car off and back on and the problem goes away. It doesn’t happen again for ages and then all of a sudden the dash lights up and the car is struggling. This has become more and more frequent and it’s now pretty much undrivable. I need to sort this out but don’t know where to start looking. A quick search around the forums and I’m thinking maybe coil packs but I don’t want to just change parts for the hell of it. 2nd post…… Ok the latest in the saga……. I decided to replace the spark plugs and coil packs to eliminate them as the problem. I figured they were over 20 years old and could do with being replaced anyway. I’ve just been out to have a go at changing them but the car won’t start. It turns over fine but won’t fire. I had a replacement CAS here so have swapped that out but it still won’t fire. Pretty sure I’m getting fuel to the injectors as I can smell it! Any ideas? Should the coil pack harness have a constant 12v feed once the ignition is on? Can I test this just by putting a meter across the + and ground pins? Is there a relay or something that should give the harness power once the ignition is on? Any ideas/advice would be appreciated. I’m at my wits end. Don’t know where to start looking really???
    • Hi guys, im a Brit who’s been using this forum for a while. I’m after some help so thought I’d come on and introduce myself. my name is Paddy and I’m an old man (46)! I own an R34 GTT in cloud white. Had it a good few years and do enjoy driving it! Also enjoy the attention it gets.  for those of you who are interested I’ve posted a couple of pics. Not the best pics in the world and they seem to of come out worse than the originals but you get the picture   Will post my issues in the relevant forum. I hope you guys can offer some advice.    thanks. 
    • Started installing the meth kit last night, managed to get it mounted so I could still access the awd resevior. Battery is located on other side I figured this was a nice spot for it. Cheers mates.
    • I saw the E in the model number and stopped thinking. Might not be correct there.
    • As soon as I come on boost that rear housing area, along with all the stuff connected to it will get pretty toasty and I'm not the type to race for a whole 10s or so 😘
