Have there been many results with the gtx3076r around the place?

I dont think on here.. I know the supra forums have some results, and also the S2K guys have some results too. A search in google gave me a lot of BS, if i have time later when i get home i'll post the links.

Have them in favourites on the lap top :) on the phone atm, sorry mate!

Marko - thanks for the reply. I'll go through and have another read, i remember reading that they are stock items in AMG's, etc? The flow rate is awesome.. Price isnt too much of a drama, would rather hold out a bit longer to get good equipment.

Feel free to post up how you go fitting it :)

Let's not turn yet another thread into a discussion about your car, please.

That GT3582R compressor map isn't right... see from Garrett:

Damn, I knew it was too good to be true. How can the maps be different? I got that one off the ATP US website.

It does say 68mm not 82mm like the one you posted too.

Dajae - I bought a pierburg but haven't fitted it yet...I created a thread on my findings and what I can tell you is that it flows more than the aeromotive stealth by a decent margin but I can't recall the figures exactly.

As a comparison, Bosch 044 flows 200ltrs/min @ 5bar whereas the pierburg flows 360ltrs/min @ 5bar.

They are not cheap so expect to pay about $450 with a filter.

You wont regret it. I am running 2 of the suckers and together they are quieter than one walbro or bosch.

Great stuff, do you have them intank or external? How did you go about fitting them, not really a drop in? I had a quick search, but only found discussions on the use of them, not so much the fitting etc. My walbro is fairly quiet (although I dont really have much to compare it to), so if its even quieter, fantastic!

Veyron.. 4 of these pumps all together isn't it?

Ok, so some results for the GTX3076R .. Turns out it probably can flow enough for ~400rwkw :) but with all things, we should take this on board with some speculation. I mean like seriously, a Focus with over 400fwkw... With an intercooler the size of a cereal box? C'mon... Lol. Ok, enough jibber-jabber, linky time!

^ Bit of a comparo with a GT3076R.

^ The focus with 600whp..

http://forums.nasioc.com/forums/showthread.php?t=2110277

^ Fairly good write up on some of the GTX range. You can see here why I'm pretty confident of the GTX3076R hitting ~400rwkw.

^ And finally, an RB25 making 534whp. I know, its not *quite* 400rwkw, but farout it's close! Awesome stuff.

I'm drooling at the thought of getting one now.. :D

There is no way that 240SX belongs to that dyno graph. Have a look at the way it ramps up compared to the power line.

There is also a very very very slim chance you would ever get a real 530rwhp from a GTX3076 and not on 26PSI.

On 20PSI the GT3076R is lucky to crack 300RWKW. 6psi more and a 10% more efficient compressor does no equal 130hp at the wheels. I'm betting methanol or nitrous help if the figure is right

On E85 I can fully see them hitting 400kw, as I've already said. On pump gas, I'm pretty confident of it NOT happening. You don't need >60lb/min of flow to make that kind of power when using flash fuels though.

a lot of dynos in the UK (if thats where the focus one is from) give readings based on some crap math for "flywheel" hp

Definately have to take this results with some sceptism, but the potential is there.

Lith, agreed with e85 400wkw would be achievable. Hopefully when r33_racer (sorry i dont know your name, im quite a n00b to the skyline community) gets the gtx on the 3.4, will see some similar results. Anyway, enough of me hijacking the thread.

Thanks for the input guys :)

Agree on the 240sx. To look at the car on the dyno it's hardly straining the dyno. To make that sort of power with a 4th gear run your going to be making upward of 8000N of tractive effort. When you are making 8000N you can tell that the car is wanting to leave the dyno - that car is barely moving on the dyno.

I don't believe it will be impossible to make 400rwkw with a gtx3076r but you will need high octane fuel min 105ron. And your may need to increase the cr to help the bsfc.

What makes you think it might not?

They take alot of meat out of the block to fit the 3.4 stroker. Have heard of a few blocks not holding up for long.

Have u tested one before?

Only what i have been told never seen

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
