you guys are poking fun but i've seen these used on pretty high end cars.. (turbo supras/TT 300zx'*/import cars in general)

they do work pretty well (i'm unsure of the tube, but i know the filters are quite nice.)

Just because you've seen them on high end cars doesn't mean they work, Eric. I've seen some pretty stupid things on high end cars.

The Weapon is worthless. Do a search on 'weapon' here on the Forum. They use big words and bogus theory to sell garbage.

This thing doesn't have a heat shield. The "flow bench" showed that the filter is of lesser quality than a K&N. There is no forced induction, so no vacuum can be created, as I see it. One smaller tube inside of a bigger tube is just two tubes. When the engine pulls in air, air goes in through the throttle body from either tube or from both. But no vacuum is created. If you really could create a vacuum, I assume air going in through would become very turbulent, and you'd actually need to have air traveling at different speeds to create a vacuum or to do anything new at all. If anything, take out the pipe in the middle to get more even air flow.

I think you can tell almost every single stupid auction on eBay. All you have to look for is nonsensical manufacturing year restraints of the product'* use. 99 - 03? Why can't the Bonnevilles that have everything fit under the hood the exact same way as the 99 from as far back as 92 use this? How come the chassis changes in 00 but is still supported, but then the support stops when the chassis doesn't change for 04 and 05? These questions are hypothetical.

i agree with willwren. i see 10x more stupid things on "high end" import cars than i do on anything domestic.. just cause daddy can afford a nice car doesnt mean they know something about cars

Those cars you listed tend to be riced out by idiots, hence why idiots buy idiotic items such as this one. They go see Fast and the Furious and they think they are experts on cars.

Anyone with a basic knowledge in science will know that this doesn't work. If anything it will just cause turbulence which will be worse.

It'* just that the 'older' motors can't handle all the stress from the added HP. They'll simply ESSPLODE!

Think it is about time that the Mythbusters put all of these "super," "wonderful," "amazing", "etc., etc, etc..." air velocity improvers to bed. Any one remember one few years back that you used to put on your car, the Tornado? Proof for me that it doesn't work, I know quite a few friends who have put these on their rigs, low end beaters and some high end vehicles, most of the newer ones had air mass flow codes that popped up, and in all cases, every, yes you read right, EVERY vehilce with the Tornado installed LOST gas mileage, and no significant advance in ponies galloping as promised....

No thank you, they can keep thier $182 (plus $25 shipping)

The tornado actually works on CARBURETED vehicles. And some TBI.

A shop vac? There is a good stable source.

Could the higher vacuum numbers be caused by a higher restriction? Less air going into the box would cause the higher vacuum reading.

A 3” ID pipe has a cross sectional area of 3.14*1.5^2 or 7.069sqin.

If you add a 2” ID pipe you reduce the total area by the area of the inner pipe wall. (0.405sqin)

You now have 6.664sqin total cross sectional area. Flow through a pipe is proportional to (c*A*L) (flow coefficient*area*length)

Less area = less flow.

Weapon-R Secret Weapon? WTF sounds like some lame video game. Anything that has the word "Weapon" twice in the product name shall not be taken seriously my friends.
