is that like a hyclone?

No.

ok, so what do they do?

I didn't realise that u can get them for the Disco 2s....

I can't speak for LR's, but we have one on the missus Prado 150 and it's like a chalk and cheese.... I love it. No lag, drives like a petrol & the missus is happy as she can drag others off at the traffic lights

We did have one issue and it might be vehicle specific.... On one of our winter outback tours, I noticed 1st thing in the morning when u head off, that the auto would not get into Overdrive nor would the cruise control work.... I would have to stop, turn the engine off and then restart and all would be good. I eventually worked out that anything other than the TOP setting and I would have this problem.

As soon as we got into the warmer climate of northern NT, the problem disappeared... I put it down to the colder climate. It's never played up again, but that's also because we haven't been into the colder environment again since.... Next year will be a good test though.... I'm hoping

From what little I know, they basically just enhance (boost) the signal to the Computer, therefore giving u a quicker throttle response....

From the Photo u can see they come with variable settings and u can also turn them off too....

Mine has the following settings:

- Off
- EC (Economy mode - very doey)
- P1
- P2

In the 2 settings u have a sliding scale that u just adjust.....

I believe the new ones might have gotten rid of the EC mode....

Happy yours works Rob,,

interesting blurb,,

Ultra Sports Mode P2

• By speeding up the throttle's response speed to advancing the instantaneous accelerating performance and explosive force. The vehicle speed bowed, doubled enjoyment in driving.

wind boost and duff are repectively a pokemon carachters wind attack enhancement and Duff is a cartoon beer in the simpson series.

I guess you could use a wind boost to blow the froth off of a badly poured Duff down at moes but you'd have to get a lot of liscencing agreements signed off to get the differing networks and producers to sign off on the cameo.


I'm unsure as to how youd get either of those things onto a Disco.

however if you mean wind boost as being one of those 12V printer case fans that show up on ebay and the likes promising to provide all kinds of performance enhancements umm, no, because well maths, entropy and hiclones, fuel polerizers, HHO converters, unicorns, dragons pixies and the pot of gold at the end of the rainbow just to add the required dash of cynicism and sarcasm..

Maths...

work out the Cubic Feet or meters or liters (whichever your fan comes rated at per minute) of each turn of your engines crank. now multiply that out by the idle speed of your engine (use 600 rpm if you don't have an actual number) and then compare that figure to the volume per minute of your fan.

now work out the maximum displacement pressure of your fan (just in case you happen to get one of the really efficient fans that does provide enough air flow to run an engine at low no load idle. (we'll ignore that atmospheric pressure is more than enough to do the job anyway) Now punch that figure through your stoichiometric ratios and work out how much extra performance that gets you. Now wind up the RPM of the engine until the fans displacement volume is exceeded by the engines induction rate. for the purpose of this we'll also ignore the losses caused by all the bits, bobs and bends between the fan and the intake valve

Entropy.

its the game with the rules written such that you can never win and at best might break even and you must play.

whats the power draw on the fan in HP?
now goto any good turbo manufactures site and see how much compressor you can drive with that much power being applied to the shaft by the turbine. (for this I'll allow you to ignore entropy because if you're like me you're entirely too lazy to work out the drop on such piffling numbers)

At this point...
if you havent already given up.

calculate out the airflow rate of your engine at Max RPM and Max load when the normal turbo is huffing all the air thats possible down the intake. Now compare that to the airflow rate of the fan and consider the nominal operating speed of the fan. Using simple ratio maths work out the ratio between the fans normal displacement and how much air your engine draws then multiply that by the fans normal RPM. We'll ignore friction, and fluid dymanics and balance and everything else and jut assume that its possible to spin it that fast.

have a good look at it and ask your self "would that hold together under that kind of stress?"

now add in some fluid dynamics and friction and reaction to the internal windings acting as a magnetic brake on the fan and ask yourself "Why would I want to bolt a restriction into the air intake? It would have been cheaper to install a hiclone"

now go and research hiclones

Now that I've finally managed to get it to come up on google (theres a good indication of how popular it is right there)

not worth it, save the money and get the ECU remapped by someone reputable.

relying on the basic prmise of keep it simple. that thing goes in betwwen the exisiting TPS and the ECU. its just another link in the chain which is one more thing to go wrong.
