bought this vortex plastic gizmo for my truck - I'll save 100Kms per tank (60miles?) on a 2000 Xterra and it do notice I have more jam at the pedal - but the guy discovered the fuel savings thing as a side line to finding more power for a carbed corvette dragster
this 10 cents worth of plastic (mine was $80 Canadian) sits in the air intake between the filter and top end of the motor - but the bloddy thing works - I'll get my money back in 3 fillups I have PMO's on an early 911 and I am thinking about buying 6 of these things anyway more of a comment than anything - with the price of gas these days... josh |

Butt-dyno's are always inaccurate. This can make mileage tests inaccuate as well. Dyno suggestion is the best one.
These 'vortex' objects work because of ADVERTISING! Period. Gullability and marketing. If these objects really work then they would be used by OEM's already. Seriously, let's use some uncommon sense (it's uncommon because common is an endangered species in human-kind nowadays). Tie a string to a fan housing and turn on the fan. Does it spiral? NO. Same applies to these spiral-max-nados pieces of crap. Even if it did cause a "tornado" effect, how is that going to continue when it reaches the plenum and has to be divided into 4 cylinders? 6 cylinders? 8 cylinders? If such a device actually worked then the geo-physics labs would have these simple devices to further their studies instead of specially equipped labs that cost an arm and a leg and then some... Sell enough of something (play the odds) and you will get some who find the device does work. Further examination would quite likely lead to defects that the device band-aides (covers up). You could get the same effect by putting a Radio Shack resister in the wiring to fool the ECU. |
