just wondering how much power rb20/25 afm's will support on a R32 gtr? I see most people use the z32 afm's but they are quite alot more expensive. Was reading an old zoom mag and they said to use the rb20/25 afm's. Im aiming for about 300 - 320awk. Will thse do the job? Also do the wires for the plugs need to be changed around or are they straight plug in?

Cheers

plugs are the same but the flex hose will fit if you try really hards LOL. you will need a re map thought as i did this to find it was very lean on the air fuel ratio.

Cheers mate. looking at that then 2 rb20/25 is plenty for what im after. You know if the plug or wirring needs to be modified to fit to a rb26?

Interesting people have not steered ytou on the straight line!!!

You'll be able to get away without changing the AFM's

Ferni did using GT-SS i believe, and im also gonna give it a whirl on my very similar setup :P

Munna's "rule of thumb" is totally wrong in its power readings.

Z32's/Q45's read a fark load more than 250/300rwkw respectively

Although its more about airflow than power anyway

well maybe i should keep the cash and go for the tune straight away with the standard afm's. im running hks 2530's pfc and have a set of sard 700cc injectors to through in. Think i should invest in a pump then instead of afm's.

Is it possible to put an external 044 inline with the standard pump without using a surge tank?

Hi, I have R32 GTR with standard afm's and 375 kw at the rears on 18psi. Havent tried to push them any further yet though. Hope this helps. :thumbsup:

Do you have a Power FC?

What is the max voltage you see, as i regularly see 5.1volts with 310hp(230kw?) at the wheels.

Anyone else maxing there AFM at similar power level?

So you say you standard 26 afm's a maxing out at only 230rwk? something cant be right there. They both read that?

Hi, yes I do have power FC. Im not sure about the volts, I dont realy play with my FC, But Ill try to find out for you next time I drive it.

Yeah mate I know, I"ve read the tables too,with 400hp atw apparently the limit on std AFM(or Scoop may prove us wrong)

But they both read roughly the same,using the sw check they seem to fluctuate within a few millivolts of each other.

Could also be due to the cold weather as I never noticed them sitting that high in the summer.

It would be interesting to see other peoples power and peak voltage..

Hi guy's, first up Im not a tuner and I dont claim to know much about tuning. Im trying to learn but its all beond me, give me a chev with a holly carb and I can tinker with that just fine. Anyway my AFM are maxed out [no tuneing resolution] but they still flow the air to support the power. That is the way it has been explained to me, and that is all I can go on. What power would I need to run 10.9 @ 127.4 mph? Fair bit of wheelspin through first gear. This was my first time out with the car as we'll. :(

You ran a 10.9? or your asking how much power you would need? What turbos are you running?

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • 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.
