Why do we need to move more water? Since when has that been a thing?

I see no evidence of proof of fuel flow in your OP. I see no evidence of looking for injector pulse. I see dubious evidence of spark. Looks like smoking gun to me.

You have to demonstrate fuel flow, injector pulse and actual spark. Any one of those not happening is kiss of death.

Technically it's DAP.

No. It means they are nasty shit with a dead short inside.

They're so cheap you could afford to put double calipers on for redundancy!

I think it curls up above akin to a lesser RB manifold and so doesn't stick out to the driver's side to the same extent as other plenae. Should be better to fit.

Ooh. Nasty. 3rd shift, 4th factory, Shenzen?

Do they have no idea how much they could have sold them for?

I highlight two words that have a tenuous and troubled relationship with each other.

Needs a price, per forum rules, etc.

Yes, but on the Dunnydoor it was for a genuine brake upgrade (albeit not necessarily a good one, given the rotors were the same, I think). This GKTech stuff is for flatbrims to put a hydo handbrake on for derp sideways action.

Are you suggesting that you can use the 450+rwkW on the street? Or are you suggesting that it comes on boost early enough and gently enough that you can have fun long before it gets to 450+? Or are suggesting that we just pretend there are no laws, no cops and no other road users and just use the 450+?

A very preliminary 2c on the AD09. These went on yesterday, so I have done <<100km on them. They replaced <~3yr old RS4s, almost exactly 15000km old. And f**ked. f**ked beyond all belief. The RS4s had been left to sit still for many months straight in 2021-22 while I was stuck in WA, and for extended periods before and after that (I was away almost all of 2021 and 22). I'm convinced the Hankooks took a flat spot that did not recover, even with let's say, 1000km of driving afterwards. They were well down into the tread markers. Complaints on the old knackered RS4s; They were hard. Had gone off nastily either through age (only <~3 yrs though!) or through using up the softer compound and running on the hard stuff underneath or from heat cycles. Whatever the case, they were completely without grip. Would light up at the rear with no provocation, understeery and oversteery. Just terrifying in the wet. They were as noisy as f**k. Between the horrible tread noise note and the whomp whomp whomp of being out of round they have added at least 2 more dB to my KU36 tinnitus. They were tramlining, wandery, all sorts of lack of directional stability. Wheel alignment was perfect. Exactly on my specs. So nothing to blame there. The AD09s? Quiet, smooth, sticky, even with the mould release still on them on damp roads yesterday evening on the way home. It's been too many years (~5) since I had AD08Rs on there, so I'll probably not be able to say whether they approach (or surpass) the qualities that I remember. But I'm already happy with them. No fair comparison against the RS4s of course, given how shit they were at the end. But then....the AD08Rs that preceded the last 2 sets of RS4s were still great to drive on when they were bald. $320 fitted per corner in 235/45-17. What's not to like?

That turbo is also not likely to make 450rwkW. 400 maybe. 430 or so if the planets align. Regardless 450rwkW is not a street setup. It will be no fun to drive on the street.

Look at the flow vs pressure curves. If you use the same pump type, it will be flowing unloaded and will move the maximum amount of juice it can.

Could be. Specs on the cams? If they're too big for VCT, they're too big for VCT. Otherwise, the actuator could have been stuffed and he sidestepped the problem. 450kW measured how and where?

Use a piece of garden hose as a stethoscope to narrow down where the noise originates. Could be from the timing belt area/VCT actuator, or cam lobe slap on lifter, or something else.

Pump to the surge has to be able to replace what the engine can use. The main pressure pump has to do a fair bit more than that and maintain high pressure. The lift pump only has to do the smaller amount and without much pressure. Makes it a much smaller power draw, even if the delivery is, say 75% or so of the main. Of course, if the surge tank is large relative to how much the engine can pull our of it, and you do not have long periods on power, then you can go even smaller with the lift pump. But in general, it will only be a little smaller than the main pump.

Well, you cannot avoid cutting or removing the dust shields if you're going to go as large as you're talking about. And you should not even ever just once consider grinding anything off of the upright or any other part of the front suspension/steering, even for a track car. Doing it on a road car should be punishable by death (and it could happen).

Functional sensible engineering trumps fashion.

No, of course not. Now you are really showing that you don't know what I'm on about. Steel wheels are heavier than the very light RPF1s that I have. Why do I have RPF1s? Because they are very light. Are they the best looking wheel? Hell no. Are they close to the optimum of light & affordable & not ugly. Yes. Yes they are. Oh. And they are black. Oh, and so are my calipers. And the hats on the brakes.
