The figures they have indicated more flow at the rear inlets (with number 3 having the most - significantly more than number 1 which was worst, I think near double). I can't work out why that would be, and with no methodology we've no way of judging whether the testing in any way replicated the flow within a running engine.
I'd have thought near double the air going into some cylinders relative to others would imagine the engine so much it'd tear itself to bits, but I'm not an engineer. They'd be getting the same amount of fuel, so maybe you just get some cylinders lean, others rich and not that much difference in actual energy released?
You do not get a flow imbalance in an engine like you would in a continuous flow test. In a four cylinder engine only one cylinder is intaking air at any one time. The firing order causes the flow to go back and forth from one pair of intakes to the other. This prevents any real pressure imbalance within the plenum. The air stops and starts at the far end allowing time for the pressure to equalize.
If they were serious and actually wanted to do testing and support their design hypothesis, they would add individual EGT sensors to each cylinder. This provides the easiest way to determine how well balanced is the flow of air through the cylinders. It is a low cost and simple way to provide science behind their statements.

They quoted test results of a flow bench test for runners 1,2,3 and 4 of the manifold.
A test of the manifolds on a flow bench has no meaning. You need to test it on an engine with a dyno. Engines do not have continuous flow and the way in which the fluid dynamics affects performance can't be determine from a continuous flow test.
Why is it so difficult for these vendors to perform proper testing? It is a commercial enterprise.
It just confuses me. I spend much of my working life building and testing apparatus for R&D. Making design and purchasing decisions without unbiased repeatable data is not logical.

According to this video, someone has tested something:
Okay. I watched the two videos. What testing was performed? I did not see any testing.

As I said, your issue is with the retailers, not Britpart. We buy from Britpart directly and they are great to work with on warranty. They send new parts right away without issue or will credit for OEM or genuine. So people blaming Britpart are blaming the wrong company. We buy a lot of stuff and the 2 year warranty is always honored.
I agree with using LRDirect as they list both the brand of the part and the supplier, so you have choice.

You must deal with bad retailers. The problem is not at the BP end. Here on the other side of the world we buy direct from BP and BM. BP is great for warranty and provides replacements fast and without any issues. BM on the other hand is difficult to deal with on warranty claims.
We don't see much variation on aftermarket parts quality based on the wholesaler. They are all hit and miss. Most things they supply with OEM options and usually those are okay.

I'm also intrigued. I asked the manufacturer about flow increases, but he got quite shirty. That's the chap that makes them, not the retailer (Fourby). I once calculated how much air a 200tdi would flow (think it was about 15cm/m). so I wanted to know what the flow capability of the double pipe was...
Bwahahahaha!!!! None of these guys do any testing. They just make parts and decide they are helpful based on the seat of the pants feel. Land Rover parts developers in general do not know what the word science means.

The Series to 90/110 change was an evolution. It maintained/improved the off road and utility use while improving the on road use and comfort. This new one is worse for off road and utility use while only improving on road use and comfort. It was not needed. They could have modernized the vehicle, making it more comfortable and better on the road while also improving the off road capability and utility. It could have easily become a world leader in off road capability and utility usage while meeting modern on road expectations. THAT would have won them new customers and improved sales vastly. But...their management has no vision and is wearing blinders.

That said, I'm assuming that this device does not include the valve in the stock one. Seems to be a downgrade without the valve.
The description is quite misleading. There is no gauze or filter in the stock breather. It is built and designed by Mann-Hummel. I might suggest they know a bit more about designing oil separators than Alisport....

If you can hear gas, something is wrong. The gas in the shocks should not move. They are possibly installed upside down.

You get what you pay for. Air to air heat exchanger design is complex. I would highly doubt any low cost intercooler on eBay will do anything to improve heat removal.

Just asking if sticker price in US includes local state and county taxes 😊
No. Sticker prices include nothing but the cost of the car. As stated earlier.
*Price shown is Base Manufacturer’s Suggested Retail Price. Excludes destination/handling charge ($1,050 for Range Rover Evoque and Discovery Sport, $1,150 for Range Rover Velar, $1,350 for Range Rover, Range Rover Sport, Discovery and Defender), tax, title, license, and retailer fees, all due at signing, and optional equipment.

Just now, SteveG said:
So is sales tax on a vehicle paid by consumer at point of sale, or later? So the price they are showing in video doesn’t include the state & county sales tax?
Tax varies by state. Some states have no tax. Some have up to 10%.

Don’t know, so let’s go by the car they actually bought and their total price as shown on the video. I just priced up the equivalent of their ~$55K 110, and it’s ~£51K here, so £9000 reduction from walking into a UK dealer.
You are mixing up the taxes.... It is cheaper in the UK. You pay more because your taxes are higher. That extra money goes to the government, not Land Rover.
-
110 - £45,315.00 ON THE ROAD = £36252 without VAT, which is $47,258 USD. $3000 cheaper in the UK.

VAT is 20%.
So it is much cheaper in the UK.
-
So I just looked at the UK site. Lowest price is. £42,920 on the road, not 45. I assume "on the road" means that is a complete price out the door. Less 10% VAT is 38628, which is $50354 USD, so that is lower that the US price before tax. It is $51250 before tax and any dealer fees.

Ok, so add another $1400, so £6K discount for crossing the pond.
That is just shipping. Does you 45000 pounds include VAT? There will be tax added and the amount depends on location and a dealer prep charge of another $2000 at least.

I see that LR are still subsidizing US sales with profits from UK and Europe 🙄 Price starts at $50K vs £45K, so a £7K discount for shipping it 3000+ miles..
I'm not sure how pricing works in the UK, but the $50k does not include shipping or tax or dealer prep.... That all gets added on.

Sure. That is a beadlock. Many beadlocks properly center the bead. That does not make them legal. If you think you are getting pulled over for the tyres, you are just as likely to get pulled over for those.

What looks like beadlocks are what is probably not legal.

Nothing too difficult it’s just that the Thor V8 manifold doesn’t have a port for the series temperature sender so I just need to find or make an in line unit to keep everything standard with the gauge.
Okay, but where are you putting it? You can't have it in the radiator hose. It will not read engine temperature there.

You misunderstood what he wrote. That was not his top speed. That was his speed after accelerating a fixed, known distance.
As far as the math. 78/70 = 1.11 ==> 11%. Power increase if this was actually top speed is (78/70)^3 = 1.38. 38% increase in power. If 70 had been his top speed, his engine would have been broken. A standard Defender 300TDI should happily make 85 which requires 80% more power than 70.
