I've ruled out the K&N and Mishimoto offerings, am on the fence on aFe (simply know nothing about it), but happy to take the plunge for CAI or Roto-Fab. Thanks for the input!

why would you be happy to take the plunge for CAI when he already proved it made no gains over stock? except what 2ft lbs torque? which is negligible

Well, he proved it had higher airflow, the car just wasn't making use of it. I'm not sure the Roto-Fab will give better results. At stock, the car doesn't really need more air. But, they look cool, and sound cool. With Roto-Fab you even get the bonus of being able to say that your engine-bay is Roto-Fabulous. I'm assuming that's what the 'Fab' stands for. And 'Roto' stands for Rotary because they really like old Mazdas.

What exactly is proof of higher air flow?

I guess for the most part it's proof of air flowing at a higher rate...

Again at this point on a stock setup id save the $ on an intake they are fairly worthless. Maybe the Rotofab will be different and until results are in I'm on standby.

Please elaborate on where you see air flowing at a higher rate.

all the cai's are halfway to an msd intake,nitrous setup,wheels with slicks on the rear etc.there are plenty of things to get you much faster times if speed is what your after,the cai are solely for looks i think,the rotofab is my last hope for actual gains but most likely ill save my money into my procharger fund

My opinon.. not 100% back by true numbers... yet. But I have a Vacuum meter and have been doing testing.

Overall I feel the Roto-fab design will rule the day here. During my testing off camera and in my garage, I built a simple design using a curved tube the size of the stock tube and with a stacked intake filter. Just bolted her on loosely and ran some runs. This setup yielded 10hp and 12trq gains. Crazy right?

Now I had to ask myself the question, why did this random redneck setup produce way better results than the CAI or Mishimoto configuration? I think it has to do with these systems removing the vacuum the stock system has/creates.

Now with a vacuum meter, the stock GM air box has suction / vacuum coming off the intake manifold. The mere fact a vacuum of any sort is present is a great indicator the motor will make use of more air. But I am also of the mind that the vacuum is needed to allow the air to be forced in to span the entire intake manifold. Unfortunately, the Mishimoto intake uses air from the motor bay and seems to lack the same vacuum thanks the overall size of the main tube and the open box design, overall allowing the air to enter more freely but under a hell of a lot less force. The Cold Air Inductions system isn't penalized as much as the Mishimoto setup as they retain a slight vacuum still but less than stock as they did go with a slightly bigger tube. But CAI's stacked filter design helps with overall flow and does show some results.

The Roto-Fab setup uses a tube system that seems slightly smaller than the GM stock box is using to suck in air. With using the semi-smaller inlet tube and forcing the filter only to pull air from the enclosed box and not the entire engine bay, the vacuum remains and in general more air flow seems to be the gain with the overall design.



The downside is, the area that the air for the intake comes in at is like the width of a pizza slice, again restriction of air flow all over. But again, making use of the vacuum that is present, allows the overall designs that use the vacuum a chance to succeed.

On the note of a super charger, procharger or Turbo, I can see a nice CAI with big filter only helping you out int he long run.

wanting to go procharger also makes me not wanna waste the money because it cant utilize any of the cai made,i suppose the magnuson,edelbrock,whipple,could though.in the older fbodies a cai could show awesome gains,but that was due to terrible factory intake designs,something that this generation doesnt have.i had to choose rotofab intake vs slicks,i bought a wheel/tire setup with slick and gained .300 in the 1/8 something a cai could never do,i would like to have the good looks of the rotofab under the hood,but without actual gains im not blowing $420

Well hopefully my tests will show some gains

Thanks man, as ever I appreciate your thoughts and explanation. On the whole, knowing what you know from what testing you have done so far and the general feel of driving your car with the Roto-Fab on it, would you suggest buying the Roto-Fab now and knowing that it will be of even more use in the future when forced induction is installed, or waiting until that moment and sticking with the OEM setup for the time being? Have you noticed any mpg advantages? I drive around 20,000 miles a year, so if an mpg benefit can be proven then an induction kit pays for itself.

If there are mpg benefits, I'd bet they're canceled out by your right foot getting a little heavier.
Off topic, but is your name referring to what I think it is? Lol

I dunno, not really but maybe. The Handle was never intended as a pornographic reference as such, but 'H Rated'. However, that pretty much goes hand-in-hand, so the reference is unavoidable. That isn't strictly the intention, though. But thanks for noticing!
