na man only looking at 1 bar or 250 to 280 is rwkw.

i appreciate what you are saying about the gt30 but it will be maxed out before i reach my goal. of 400rwkw.

So do you want 280rwkw or 400rwkw? Theres a big difference when it comes to setup....

it has a 0.5 to4 front housing and 1.06 rear but i'm gonna change a few things soon to a .7 and .86 rear. John the ultimate goal will be around 400, as my weak points at the moment are the box and clutch which is going to cost around 8k so i'll save that up and get ppg gear set and nismo twin plate. so atm i'm just building it to be able to do what i want too, when i'm going to do it.....if that makes sense.

I take it you are using the factory boost pickup point - ie the nipple at the start of the scroll? If so that point has a higher boost level than manifold pressure. The pressure difference between the two increases logarithmically with airflow rate.

If you change to manifold pressure as a boost source for the actuator you will generate a lot more boost.

^^^^^^doesn't make sense as this is a 3ltr, it also has bigger cams so i'm expecting it's go to drive like a strong na off boost, and beside i've seen gt3540rs on sr20 with plenty of mid range, the turbo was actually designed for 2.5 to 4 ltr engines so being a 3 i'm kinda right in the middle, and if a rb25 will push a gt30 to 300rwkw and have plenty of mid range i can't see why a gt35 on a over sized forged rb30 would do any less justice. the engine is being built to handle a flogging.

You do realise bigger cams are actually going to make it weaker off boost yes?

It's not a high comp N/A motor you are dealing with here.

so in turn it would also read "true" if i where ton read it from the manifold and not the turbo side of things which would allow me to adjust it accodingly for what pressure i want???

You can use either boost source. The reason ford use that pickup point is to allow better control at higher rpm. And by better control I mean better ability to lower boost.

right so nismoid i would be better running the factory cams ie rb20 ones as i was only going to use stage one tomei items. Also what is the safest power level and rpm of a standard balancer as i cant find the info.

Not enough for you. I am running a max of 6500 to protect my stock bottom end and N1 pump but if you want to rev high you should get a better balancer.

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
