Trent,

Just like to say good luck at the upcoming Autosalon.

Having seen the process of the engine work im sure you will crack the magic number you are aiming for :)

Thanks Dave,

We were extremely happy to get 1000hp on E85, not sure if that had been done before, but to push it further now we are switching to c16 and more boost. The engine had perfect compression after the power cruise event, so we are happy to step up the power and see how it goes. Obviously the GT4788R is a big turbo, so there should be plenty of room to move from its current power figure. Fingers crossed it performs well at Autosalon. If it does, we will make the trek to Autosalon Sydney with a few more goodies added to it to go even further.

200hp @ 6000rpm, 800hp @ 7000rpm. :whistling:

Holy. Shit. Talk about a serious PUNCH, just a shame it takes so long for it....why so little power at 6000rpm though? I mean my R33 pulls harder than that lol

The engine is designed for serious horsepower, so there has to be a fair number of compromises along the way with the build to ensure it will handle what we plan to do with it. One of those compromises is response. There are many factors, but some of them are comp ratio, camshaft size, camgear tuning, exhaust manifold sizing, the size of the turbo etc. We will be compensating for this with a shot of NOS, to get the car onto boost, hopefully around the 5500rpm mark. That would make the setup a lot more enjoyable, although it is pretty freakin cool when it comes on! BTW, there is no lag between gears. It falls back onto full boost.

In all seriousness have a look at wizard of nos nitrous products.... they are light years ahead of the holley/NOS- NX- Nitrex etc. I've had first hand experience with Trev's gear on a 1800hp GT40 (plus nitrous) at some standing mile events and I have bought a full direct port set up for my own RB28.

It's exy- but it's well reaserched and tested technology.

We were just going to use a Zex wet, single fogger kit which we already have here, controlled by the ECU to turn on and off based on rpm and boost. For spool up, that should be pretty easy to achieve.

      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

      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)?
