not sure, but......

I have seen that thing advertised on TV. I have spoken with 2 diff peeps on this subject. One said he can tell such a difference that he is going to put it on every car he owns; the other said he wasted his money. I know this doesn't help much, but the reasoning behind that product make perfect sense. To me anyway..lol

Actually it does not increase the amount of air bieng sucked in rather it blocks air flow causing a decrease in preformance. Here are some dynos I pulled from the bay area probe club.Spiral Intake a.k.a. The Tornado (Back to Index)
Here's what I found on the dyno. The data is uncorrected and smoothed (to avoid getting too many unbalancing peaks) to S=3 on dynojet's software. I made six passes on the dyno. Two with the Tornado unit installed followed by a 20 minute cooldown (with the engine idling) and two runs without the Tornado installed. Following yet another 20 minute cooldown with the engine idling I proceeded to make two more runs with the Tornado unit installed.

Run #1 w/Tornado: 145.1 HP, 147.3 lb-ft Run #2 w/Tornado: 145.3 HP, 146.7 lb-ft

Run #3 noTornado: 148.0 HP, 149.8 lb-ft Run #4 noTornado: 146.8 HP, 149.3 lb-ft

Run #5 w/Tornado: 145.6 HP, 148.8 lb-ft Run #6 w/Tornado: 146.3 HP, 148.4 lb-ft

As you can see from the above numbers, coming in "hot" from the street produced the lowest numbers. I did allow for about a 10-15 minute cooldown before hitting the dyno the first Time. So perhaps the second run wasn't surprising, with the car probably being a bit cooler. The third set of runs is what put the nail in the coffin when it comes to the Tornado. Although the third set was a bit improved over the first set, it was still visibly lower than the second of runs. (thanks to JTT)

Yet another snake oil automotive product

And with definitive proof it doesn't work on the MX6, I'm closing the thread :E
