Bumbebee, STFU, what WRRR is saying IS CORRECT!If X turbo, can supply Y amount of air, at 12PSi, and make 260RWKW, and you ADD another turbo, the ENGINE will still see Y amount of air, but each turbo will only supply Y/2 Air each. Hence, 2 lots of Y/2 air being flowed through each turbo, makes Y amount of air entering the engine. STFU, and stop posting, you're making this place look stupid.

If you take the RB26, and use ONE of it's turbos, the actuator still kicks in at 12PSi say, and you get x amount of air in CFM flowing through that turbo into the motor. Now add a second turbo, feeding the RB26, the actuators still kick in at 12PSi, but now, each turbo is moving x/2 CFM of air. Therefore, the turbo itself isn't working as hard, it isn't spinning as fast, and shouldn't be as hot. Mind you, the motor is still receiving X amount of air, because you have two turbos, pushing X/2 amount of air... Hence 2*X/2 = X... It's the flow of air through each turbo that drops, for the same amount of pressure. Pressure is just the resistance of the air entering the engine... It is not a calculation of flow.

Redo the wiring.

Get another known working ECU, and test it. Check the injector loom wiring. (Not just the plugs, but the actual wiring...)

Cams not set right? Valve float? You haven't mentioned springs that are being used... It looks like it ramps up quite nicely, and just noses over... As if the cams are set for response...

*Smacks head against wall* Back pressure KILLS power, you NEVER want back pressure, EVER. The choice of 2.5" is to do with harmonics, and gas flow speed VS cooling. Mainly, Harmonics.

*Yawn* Nice Tanty... As to why you "must" (PS, I never said you had to) I'd just like to see a touch of evidence that your missing power is back from something that can't affect it. MissR34: You seem very stuck up personally to me, and stubborn. You're unable to listen to those who KNOW what can and can't affect your PowerFC to alter it's fuelling and timing. Those of us who have told you the Knock sensors can't "fix" this missing power, would like to see how you magically got it back. Oh, and the last person I saw throw a tanty like that was about oh... 5 years old, and an only child... You really need to be less defensive of everything, open your eyes, and accept some Constructive Criticism. If you do, you might find your issue with the missing power. Hell, it could be just a set of plugs fouled, it could be bad fuel, your AFM might be stuffing up and want cleaning, you could have a vac leak. But there is no chance, knock sensors will affect the PFC. If you accept this, then those of us here, can help you find the issue. But firstly, you need to accept, knock sensors won't affect your tune AT ALL because you run a PFC. And this, is why people are saying your tuner may not be the best to listen to at the moment, as he doesn't seem to understand this fact from the PFC.

Can agree majorly on the just "me time" thing badly! And the loud things to block out others. As to the leaving it outside... I found for me, I like those really really close that i have a brilliant emotional attachment to to know... So far... I haven't really found anyone close to me to let know... People know I've been depressed in the past, but not that I still feel it coming back on days, sometimes it lasts just hours, other times, weeks, sometimes a few months. But my car, my close friends, and my family are my life, they keep me sane... Hopefully long enough till I find a girl. But my most relaxing thing, or most lifting thing, is buying things for my car... Just earlier, I bought some new cam gears... Felt so damn good after it! My car, really is my release. So, who can I see for this HOD test to be done around Wollongong/Sydney, and how much will it cost?

When you put the cam gears on, they'll have a marking on them that will align to the backing plate. Set them to that. Then, the crank pulley as a mark on it, that aligns to a notch, align it to that. Put the timing belt on, crank motor over 2 full turns of the crank by hand, inspect these 3 markings still align properly. If they don't redo them.

I gotta say mate, I'm on two sides of this... I've had the anger management issues and depression before. For me, the counselling didn't do much, as really, at that stage, *I* didn't want the help. But years afterwards, I've reflected on things I've been told in those sessions, and from talking to other people, and now I'm completely different. To this day, I'll walk away from arguments etc as I can't stand yelling voices. But as for you, my brain is saying "stay strong, help sort her through it, you can do it!" as I know if I were in that position, it's what I'd be thinking. In fact, last year I was in a relationship where I was getting fairly used, and I didn't really realise this until after we broke up (She cheated, it ended) but now, I'm 100 times happier, yet I'm single, so nights can get rather lonely, and I really need my friends around me sometimes otherwise I crash down into depression. I found, I had to find my own ways to deal with everything, unfortunately, sometimes people find me a tad "cold" for it, as I do lock my inner self away from a lot of people, but it does help me not to go all angry style at the drop of a hat, but at other times, it can also cause depression issues... It's all about me getting my balance. Personally, I'd try the test that has been suggested, also the pill, yeah, that shit f**ks chicks up bad, then try and get her some one on one help, and a bit of group therapy, and I'd also suggest, get yourself some one on one help, or at least find a REALLY good friend that you can really open up to, a lot of guys have issues doing this, but it does help.

Just thought I'd check, as to me, when someone says "it's rattling at 3000RPM" I'd be thinking "OH god, engine is on it's way out and knocking" But if it's from the exhaust, and you're sure it's the exhaust note sounding "rattly" then that's all good.

Whilst I like saying everything done to my car is all done in my garage, the blood sweat and tears sometimes doesn't feel worth it when shit all goes horribly wrong and there's major f'uck ups, as I find I quite often lose my focus, and interest for a while... Only right now, as I'm getting things back together am I starting to be slightly happy... Although it's still stressing me money wise that I may not quite finish everything when I want too...

HOLY SHIT! Ever thought of putting individual throttles on the RB25? Not like it hasn't been done before... Oh and the butterflies won't affect LAG or the BOOST THRESHOLD between either of them if built right. It WILL affect throttle response... These are THREE totally different things.

My question is, is this "rattle" from the exhaust, or is it a rattle from something else... All that you've said is "rattle" at 3000RPM... Are you sure the noise is from the exhaust?

Why is an RB25 going to be laggy compared to an RB26 making the same power? If you've got a really laggy RB25 making the same power as the RB26, then the RB25 isn't built right... It's only a 100CC difference, not overly noticeable, at all on the street. Now compare the RB25/26 to an RB26/30 and the latter will make much more power, with the same lag... And just remember, Lag and boost threshold are two different things...

Define better. Looks, flow, noise?

For some reason I didn't get notified of this reply... :) I don't have any current photos, but, I'll attempt to slide under the car tomorrow and get some photos of the setup, where the car is currently sitting, I can't move it, or jack it up, so I'll try my best to get some photos, but they won't be great, when it goes up on the hoist next, I'll grab the good photos. Please note, the dump pipe WON'T be bolted up. I'll try get the measurements as well of what sizes I'm running length wise, I know it's definitely a 5" and a 7" (midd and rear) I'm thinking of trying to make it even quieter, so I might lengthen my mid section, and put the front muffler on, just to see how quiet I can really get it.

Check the breather hoses to things like the charcoal canister. If they crack, you'll get really strong fuel vapour smells.

If Cara could find the real problem, and then post her dyno "figures" and then back up the power with a good MPH, not an issue... Until then, those who know, are just sitting back pissing themselves laughing at her for believing the knock sensors are the culprit. Come on Cara, dyno it, and then drag it!

Once it goes back together Adrian, Kon's expecting somewhere between 450 - 480 hot ponies from it at the tarmac melting stage... It already lights third on the roll before it came apart again... But, I don't see what this has to do with a sensor on a car, that affects absolutely nothing in the way of the tune, and hence, won't affect power, or driveability.

*Dives into a garbage bin at 200 killer wasps*

So a sensor that provides feed back to a system, which does NOTHING with this feed back to alter ANYTHING, not even pull timing or change fuelling... Made a difference on your car? Wow... I really want to know how it did that... Unsure if you know, but having a knock sensor, having a dead knock sensor, and having no knock sensor, on a car with a powerFC will make it run EXACTLY the same... The only thing you'll notice, is the CEL flashing if you actually get knock, (Or if it's cactus it'll flash without there being any knock, and without the sensor, it won't flash at all) But glad to see you picked up 50 bajillion killer wasps at the rear wheels... So, when are we going to actually see this thing make a pass down the quarter to back up these over inflated dyno figures? Or, are you too scared to run it down the 1/4 as it'd prove you don't have all those killer wasps, just like you won't post a dyno sheet of how it's running now as you know the knock sensor did sweet f**k all, and if your mechanic told you it made a difference, you should quit going to him. If it's you saying "it made a difference" get over the placebo effect.

Knock sensor change was an epic failure I bet...

Driveway to garage... That's a long distance... Do you not look in your mirrors?

I run a 3" straight through system, with a cat, and two mufflers. My exhaust is loudest at idle, and even then, it's legal. Open the throttle right up, and all that you can hear is the engine itself revving, and the turbo induction. My whole system is custom, the only off the shelf item is my cat, my mufflers are all custom built. If you're around Sydney/Wollongong, and you want a really nice sounding car, that's quiet, with HUGE flow, PM me, and I'll pass on some details for you. Oh, and when my mufflers were built, we were looking going "Hrm, we can fit X, but we'll just stick to smaller for now, if we want quieter, we can make this one bigger, that one bigger, oh, and throw another one in there..." For reference my rear muffler is a 7" 650mm round custom muffler with fibreglass packing, straight through setup. And mid muffler is a 5" 550mm from memory (Or maybe it's the 650 and the 7" is the 550) and it runs fibreglass packing as well, and if I wanted another one, I was going to lengthen the 5" muffler to 950mm, and also chuck in another 5" 650mm stainless packed muffler BEFORE the cat (Hence stainless to deal with greater heat)
