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.

I'll bet its fun.

What secret spec cams are you running?

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.

Big ones. :dry:

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.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
