To good to be true???

Just been doing the evening troll through ebay and I found this:

http://cgi.ebay.co.uk/SuperMAX-35bhp-30-fuel-saver-for-Porsche-944-968_W0QQitemZ170396224236QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item27ac680aec

In brief it's a doo-dad you put in your air intake. It is meant to produce a vortex that then give your car more horse power and better fuel economy due to the richness of the air.

I was just wondering if anyone has seen, heard of or used one of these as they sound too good to be true....?

I think the man may be correct[8D]

Too good to be true. We did stock them, but didn't really sell them as we're too honest when people ask. If it was that simple to make an engine better in so many ways, wouldn't the manufacturer put one in in the first place?

 

[kevinyearley]

Thought as much. Would have been nice if they did, could have fitted them to all my mates cars, started my own little 'tuning' business, lol.

Cheers for the quick replys guys.

Oilman,

Off topic, but have you got anything to do with any Land Rover forums?

Yes, quite a few. You'll find them here

A good laugh.....it was discussed on here a while back. My reading of stuff by experts (which I'm not BTW) convinced me that tinkering with air filters, porting heads, and the like was all about cleaner, turbulence free, laminar flow in the inlet, the exact opposite of what this product promotes!

Wonder if it would improve exhaust flow too if shoved into the tailpipe!! Perhaps it would whistle too....

Yes the consensus on that particular piece of "technology" wasn't exactly enthusiatic. []

Its strange too how many satisfied customers have left feed back.I wonder how many are genuinely satisfied.[8|]

 

[oilman]

True, but that's ebay. Up until it was changed, people were always worried about getting negative feedback so that is probably a large part and also it will be a placebo to a lot of people, they will think their car is faster, so they are happy.

I best cancel my order then. I was going to get 2 as that would be +70 bhp. [8|]

From my past experience with motorcycles vortex's do work http://www.hillbilly-motors.com/html/svvs_vortex.html, there used to be an aftermarket modified airbox for my bike that had a little cone shaped point going into the intake, created a vortex and increased power slightly, it worked and the manufacturer even incorporated their own version in the air box cover for the following model.

I'm not convinced however that this item on ebay manages to do the same using a few slits of metal, unless the vortex is right over the intake (as it was on my bike) I cant see what benefit it can provide if any.

I can see how the motorcycle one would work directly in the inlet tract very close to the cylinder, which is why it wouldn't work in a set up like ours with great big long and curved inlets. It would need one in each tract.
I think I'll leave this one.

Don't see how vortexes will work at all. Intake design is all about trying to increase air pressure inside the intake. Moving air has a lower pressure than static air therefore if you create a vortex in the intake you are increasing the air speed and therefore reducing the pressure and the mass of air in the intake = less power. Also it takes energy to create the vortex and that energy is being taken from the engine therefore less power again. All this thing is doing is creating a huge restriction in the intake and sapping energy from the engine.
