Custom Intake
Well after the obstacles chino ran into, I decided to give it a shot myself. A little custom work, and I was able to to get a SRI installed with no cel codes thrown. Right now its very generic and installed, but I will be working on cleaning it up, changing coupler colors and hose colors.
There is definately a noticable change in sound, mean as shit is how I put it HA! Performance wise I noticed a very small amount at mid and high RPM. If there is enough desire, I could definately get some of these kits together for anyone who wanted one. Its not gonna be so much involved like chinocharles was, I dont have enough time. But I could definately fab them up if anyone wanted to. heres some pics.

Nice job. What is your MAF sensor mounted in? In case you didn't know, it needs to be mounted so the actual sensor is exactly in the center of the pipe.

Its a little off center, can you explain why it needs to be mounted dead center of the pipe? What about CAI's where the piping is longer and you cant get the sensor more centrally located? Do you mean it should be located a little closer to to the throttle body?
Like I said I am not 100% done with it, I wont say I am until I am completely happy with it. the maf adapter plate lines up perfectly and fits great. I want to try some more trial and error on the silicone hose, im thinkin a 45 degree angled piece would work better... when im done I will get pictures together and probably write up a how to piece it together yourself and also offer others who dont have the skills/tools/time to pull it off themselves... feel free to ask questions guys

I think your placement of the MAF in referance to the throttle body is correct.
what material is it made out of?

velocity profile
Quote:
The MAFsenser is calibrated for the velocity of the air at the center of the pipe... pm me if your interested in suggestions to maximize air flow...i have studied the topic extensively... Last edited by fu_im_from_texas; 06-17-2007 at 02:24 AM. |

where did you get the MAF adapter and/or the pipe with the adapter already attached?

Soooo....you're saying if off center the maf doesn't sense as much velocity and would send less fuel, causing a lean condition?

just a guess though...depends on too many conditions to make a blanket statement...i think a lean condition would be worst case... |

I get you texas, the piping is the same size as the original accordian tubing. the maf adapter plate doesnt look like its any thicker than the stock mount, but then again I eyeballed it. So I will pull the pipe off and check it again.
I was driving on the freeway and either the svs or cel light came on, i tried to check it with my code reader but nothing came up. I unhooked the battery lastnight for 10-15 minutes to see if this would clear it up, we will see.

For future reference, it will be about 50 miles before your ECU throws a CEL due to anything airflow related. Therefore, to properly test a setup you have to clear the code (disconnect the battery) and drive 50-80 miles before you can say for sure it throws no codes. At any rate, way to be proactive and give it a shot. Good luck!

the stock maf sensor is at the mouth of the airbox. I think reynold's number would not be significant in a 2.5"ID tube. Laminar and turbulant flow are calculated for use in fluid mechanics. but as an example the chart you have show a coefficient of friction of .04 or four-hundredths. Air probably produces less friction or drag at such low velocities. |
