So first 1000km feedback.
I can definitely feel an improvement in lower end power on the Paj. I can not sea an improvement in consumption on the road though. I still get round about the same consumption at 120km/h as before, if not a little worse.
Will keep a close eye on it the next two or so tanks.
Some feedback as tested by Popular Mechanics in US. Seems like you might gain lower end but loose a bit at top end. Did you notice any difference, good or negative at high revs.
We strapped the trucks down to a pair of chassis dynamometers and ran them dry of gasoline. Then we added a measured quantity of gas, and ran four dyno pulls to determine horsepower and torque. Next, we accelerated to a corrected 70 mph, set the cruise control to keep the speeds consistent and ran the trucks dry again. This gave us a base line of each truck's unmodified power and fuel consumption.
We gassed up the trucks, installed our gas-savers and repeated the tests. (We didn't check for emissions, figuring most people who buy these products are fighting a holding action on their wallets, not on the environment.) Here are the gadgets and how they performed.
TornadoFuelSaver
VORTEX GENERATORS
These devices, which are usually installed on the upstream side of the mass airflow (MAF) sensor, use stationary vanes or, on some devices, spinning blades to make the inlet air between the air cleaner and intake manifold whirl around in a mini-tornado. This vortex supposedly mixes fuel more thoroughly with air, which means the fuel will, theoretically, burn more completely in the combustion chamber. Trouble is, there's a lot of intake tract downstream from these devices designed to maximize a smooth airflow. Turbulence, coupled with the restricted airflow caused by the device, can only reduce the amount of air sucked into the manifold. Less air means less power.
Again, we tested two devices. The TornadoFuelSaver is a nicely made stainless steel contraption, available in an assortment of sizes to fit most vehicles. We installed it on our truck's intake tract immediately upstream of the MAF sensor. We purchased the second device, the Intake Twister, on eBay. It was crudely handmade from sheet-aluminum flashing and pop rivets. It looked like something we could make in about 10 minutes from an old soda can. The staff at UTI was reluctant to install it: The bent sheetmetal vanes looked as if they might break off and be digested by the engine. The device is one-size-fits-all, and is simply bent into a curl to insert it into the intake duct.
THE DYNO SAYS: Both devices reduced peak horsepower by more than 10 percent. The Intake Twister increased fuel consumption by about 20 percent; the TornadoFuelSaver provided no significant change.

I can honestly agree with you 100%. I removed it last night to check what how the performance is without it. Lower end I now don't really feel a difference, but I definitely have better high end than with it. Will be taking back to the gentleman probably today or tomorrow. I think it would work better on the 300Tdi defender as there is almost no electronics to optimize airflow, etc etc.
I did however do a quick service last night, oil change (delo 400) and air filter. And that already made a HUGE difference on the performance. I saw that I need to check the air cleaner more often, cause darn she was black.

Still think it was good to try it and verify the worth of it. It might work in some applications like you say and you never know when some of these okes actually gets something going that does improve your drive.
Yeah boy!
I can eventually get off my hands, which were getting numb from a big guy sitting on them!

4e, I was waiting for ur input on this!!!Fitted it to the defender. I can feel a diff, a considerable difference actually. especially lower down. she's much smoother through the gears. weather that will make a difference on the consumption I can't yet say.
Either way, it definitely does not work on the 3.8 V6 Paj.
Drive it for a few tank fulls, logging consumption accurately.AndreBenson wrote: Fitted it to the defender. I can feel a diff, a considerable difference actually. especially lower down. she's much smoother through the gears. weather that will make a difference on the consumption I can't yet say.
Remove it and try the same (inevitable) "careful" driving style for the similar distance, again logging the consumption.
Then HONESTLY convince us (and yourself) that science lies!

I intent to do the same as I did with Paj.
Wrote down the figures without, then with , then without again....
