I'm doing this to help the N/A guys out with out having to do anything major.
I dont appreciate my efforts being called a waste of time...

 

A fair request... I appreciate your effort! I'm also very interested in your results. Dont let people detract from your efforts. Continue, you have my attention.

 

Wrong

 

So you cut the safety brackets off of the headlight right?

 

Well, admit you're not doing anything profound - with really little value to us.

However, I don't blame you. I like to do similar things, whether beneficial or not. It's good to see young minds working.

But really - be mindful of your elders.

 

How do you know? Seriously.

Where was he rude to his elders? If you want to talk about rude, how about telling the kid what he's doing is of little value?

Campeck, when you test this, also run the tube through the hole in the fender and place the filter down into the fender. Get some real length on that and try a bunch of lengths.

 

yeah. I need some extra tube for that. going to check out NAPA in a while.
The headlight bracket isn't cut off....for now.
I popped the headlights up and disconnecte4d (edit: haha..l33T Sp33k) the motor so I wouldn't accidentally put them back down.
I may have to cut it off though depending on the final setup.

serge. I want to be able to maybe market these if i can make a good one. so It would benefit us.

 

In relation to changing the intake system. Porsche uses the vairable length intakes on the 911/997's.

There are two sides to the intake; before the plenum and after the plenum. Before the plenum is the AFS and the filter. Changind the flow into the AFS may marginally change the AFS response. More than likely not so much you would notice. This is akin to washing and waxing the car. You would swear that it put on 20 more horses.

The plenum on the intake is the buffer. Like a large capacitor. It ignores anything on the up flow side.

Unless you stick pressure transducers all through the intake and use a dyno this is a waste of time.

And it's not aerodynamics that governs the flow in the intake.

 

All this arguing really worth a 5-6HP improvement????

 

CAMPECK - PRESS-ON and ignore the critics - they know not what they say. I will look for all the .1 secs and 5hp changes I can find. We are starting with only 150hps to begin with!

 

If we can gain 5-6HP from a really simple, minor modification, why not?

Although I do not think your G-Meter testing method is very valid (WAY too many variables), your ambition is great. Get some proper testing done on a dyno, and maybe you can help lay the CIA/cone filter debate to rest!

 

dont worry.
some ppl are just ignorant.

 

Ashton, go for it. I was disappointed with my results, which was why I stopped the project. Sorry if I was giving you sh*t in any way. I say go for it, but you don't have to lose anything if you do the project right and your budget won't be exceeded. Good Luck.

 

Big deal. A lot of companies use variable intakes. It's not really that special.

Well, keep on with what you think you know. The FACT is that resonance tuning of CAIs does in fact work and the gains on a lot of the popular cars that use them are real. They are repeatable and documented in controlled dyno testing. The plenum does not make the upstream side irrelevant. My fear with the 944 is that the barn door AFM is impediment enough to negate any improvements in air flow. Shouldn't though, but you never know. The AFM barn door could be the biggest buffer in the system.

I don't know where anybody said anything about aerodynamics governing the flow. Fluid dynamics (of which aero is a part) and resonance tuning does for sure.

 

For me, 5 hp is massive! I am extremely restricted by the rules and the intake before the AFM is free in my class. I will definitely be working out a CAI for my car. If Campeck can do some testing now, that will just get me that much further. I'm still concerned about the barn door and how it may affect the flow. I'm also concerned about the shape of the venturi in the adapter. The tubing attaching to it is round and the openning in the AFM is rectangular, therefore a complicated adapter would be necessary to keep the air flowing smoothly and minimizing turbulence.
