Air Induction Systems, Voodoo, and simple test

[DCColegrove]

I did. I think you should go threw with your plans. also I noticed when I did the M30 AFM it made my car run very lean untill I did the injectors to match, doesn't that mean it flows better than the stock AFM? but I do see how a bigger door could mean a bigger restriction.

You're missing it...

It's not a question of restriction but velocity...

If you read the original post all the way through I think you would see that why was my original question.

eric lukas was the original bathrobe clad god of the CAI. you guys are mere commoners

No... I think Steve Dinan beat him to it. (now there's a guy there is no point in arguing with)

why is everybody making CAI now?

or can you gain more by making it a similar design, but smaller so you have more velocity VS larger bore and slower velocity

[der affe]

so are you talking about running a smooth 3" tube with a bend and a silicone or rubber boots at each end to allow for flex that may be needed in the intake boot. there by straightening out the air path, but still keeping it flexible without disturbing the air path.

Wait, so if you add an afm with a larger door that runs the same as the original m20 afm, it DECREASES the amount of air going into the intake maniforld? I would think the amount of air going in would be the same, if not more. I roll an m30 afm and haven't noticed a hinderence at all.

In a word... Yes.

(on a "stock" m20 configuration)

i hate to point out the obvious but you fuckers are driving 20 year old single cam 6's. change your stock air filter once a year and call it a fucking day.

True...

But that's not very fun...

Some of us have this thing for pushing the envelope...

There is a certain elegance to the nasty old M20s that is hard to recapture in the more modern power-plants.

edit. i agree with blunt as well, the head is a huge problem.

this doesnt make sense

Why not?

The additional volume of the larger AFM is negligible in it's performance increase because it only serves to slow down the velocity through the entire system...

An AMM is more accurate and has no limit on what It can sense flow and density wise but in actuality it will only increase the throttle response unless the flow through the whole shooting match is increased to take advantage of the AMMs capability.

The M30 AFM will only give you headaches the only step up is an AMM and that's not much of a step on a stock M20.

[DCColegrove]

Build it, test it, and show its better than the stock setup or any homemade concoctions and people will buy it.

Period.

Be sure to set it up for the M30 AFM though. ;)

I'm already running it on my M20 powered car and have had a whole different system for the M42 for several years.
