vortexing the intake?
 
are all these gadgets that say vortexing the air into your intake makes for better for your car is this true? (ie: tornado)
thanks

DONT BUY THE TORNADO!!!

They break and damage the engine.

I dont know if they damage your car but I can tell you that they will SIGNIFICANTLY DECREASE performance.

It is basically the opposite of a CAI. A cold air trys to make the pathway to the intake as simple as possible, a vortex makes it more complex.

Any sort of restriction in the intake will decrease performance and just imagine the destruction one of those little wings would cause if they broke off.
A word of warning on CAI's they can cause turbulance and may deminish the accuracy of your MAF. In other words if it isn't designed properly you could end up running lean and in turn increacing detonation. On a turbo car a CAI will yield very little in terms of performance unless you are in the 400+ hp range because the air from the turbo is being run through an intercooler anyway, and so the only performance gains will be through less restriction in the filter. Basically, there are better places to put the money such as EM.

WOW, do not do this. what a waste of time and money. It is crap.

vortexing works when two things are trying to go thru a small space at the same time(like the water swirling in the soda bottle that you see on the tornado infomercials) the thing is, with a car's intake only one thing has to go one way! air goes in, nothing goes the other way. so what the others above said is true, and this is why.

CAI's, IMHO are really only for the sound that they provide. Actual engine performance is gain is minimal so I only think they are worth the money if you want to hear your engine more. Not that I dislike the sound, because I do. ;)

i have a dyno appointment on my way home from work... i have a pretty good feeling that you will be VERY wrong about that last comment.

RE: vortexing the intake?
 
Perhaps I will be wrong. I simply stated my opinion and if it is not correct, then so be it. I am just speaking from my experience with CAI's and what I have noticed in my time dealing with and modifying cars. I have never personally seen more than a 5whp or 6whp gain on a dyno come from a CAI only install.

Bender 05-23-2006 06:32 PM

RE: vortexing the intake?
 
you say 5 or 6 whp like it is nothing... it isnt great but with these cars only putting what they put out, that is a pretty big jump.

on my camaro i got a 7 whp gain out of a cai (well wasnt really a CAI due to the intake set up but basically the same thing)

I am thinking I will get the same here due to the turbo.

S60T5 05-23-2006 06:45 PM

RE: vortexing the intake?
 
My opinion of a 6whp gain is minimal. Your opinion maybe that it is a significant gain. I cannot argue with you on your opinion. If you are happy with that gain for what you spent for the CAI, then that is all that matters.

YOU WONT GAIN ANYTHING FOR DOING THIS TO YOUR CAR OR ANY CAR. 1. I DOUBT IT IS DYNO PROVEN 2. IT IS WORTHLESS DO NOT DO THIS

CAI results- 8whp 8lbs torque


BUT what S70 said... listen to that

where did you get your CAI from?

Can we see the dyno graph please. Also a stock dyno to compare.
