I make this public, I think this is probably the highest HP out of a high flowed R33 turbo ever archived with 98 fuel internally gated. This is our PU high flow option.

Once thanks to Trent at Status for excellent tuning work.

Fully stock RB25det engine with forged pistons only.

800cc injectors, Nistune ECU, FMIC, Exhaust and 3inch intake pipe.

Car peeked 305rwkws @ 21psi, full boost by 4200RPMs. The average run was 300rwkws.

Yellow line is straight off high pressure actuator, no boost controller. Green line is with boost controller.

stao took me for a spin with this turbo last night and in a restricted form too (with std airbox) and wow what a thrill when it hits. I want one!

What makes you say the airbox is causing a restrction?

Thanks for support guys. Details of this high flow through out development and manufacturing is in our high flow thread.

I took Jeff for a spin that night with air box lid on. Very noticeable difference in how car reacts to throttle compare to a POD. The car was dynoed with a POD and 3inch metal intake.

I got some video footage I will put up later on.

Might be valve springs, I'm not too sure. I did hear a light pop just before the rev limited kicks in. That little dip is always there. Any thoughts would be great.

that is in .82 rear. The difference with an Air box would be, well it sounds very differenct lol. It just doesn't pull as hard, and feels like I'm down in torque.

Is it running out of flow around 6500rpm and hence the nose over?

Or is that being caused by something else?

I dont know much but I dont understand why everyone worries about this so much, Its just a high flowed stocky and usually I'd be clutching by then anyway..

you wanna bounce of the rev limiter get a better turbo (and a better engine)............

This turbo has almost 150kw gain from 3500 to 4500rpm and for the street legal ,that is crazy and affordable power .....

Well done Stao :ermm:

be interested to see a pod power pull followed by one with the stock airbox. i'm sure there is a point where the stock airbox becomes a restriction but it would have to be up around the area you're operating in.

great result!

congrats on the results mate, iv just purchased a 0.63 version of these turbos from another forum member. what can i be expecting from that?

Would you know the member's name and which forum it cam from? They all got different profiles in them refer to what the original customer wanted to do. Or you can pm me a photo of the comp wheel and turbine wheel I should be able to tell you what it is and what its capable of doing.

    • As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.
    • I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc. 
    • Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.  
    • So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
