Re: Airbox Mod? (xman03)
don't it helps clean up the airflow...

We already shaved some from the outside, it's gonna be as thick as a soda can if we port it

. The issue is people having negative pressure in the airbox especially tuned so I was thinking taking out the plastic mesh would aleviate the problem.
- Looked at some other forums, seems like a good idea to leave it on. O well.

| I cauld my friend. Id leave it there if you need more air flow lets port out the charg pipewe can shave about 2-3 mm off it |

Re: (xman03)
For under $100, the IPD Ram Air kit will alleviate most all of the vacuum created by the spooled turbo. That's probably the best way to combat vacuum at WOT, for example (although it obviously has a better effect in any gear other than 1st).

Re: (Oceans60R)
This is the expected result. The grid is called a flow straightener, it helps distribute the flow across the surface of the pipe so that the tiny sampling area of the MAF sensor actually represents what is happening, as accurately as possible.
With turbulent flow across the MAF if your intake setup sends a stream into the tiny sensor but other parts of the pipe are seeing less flow the reading will show more airflow than actual. Vice versa if that "jet stream" of sorts avoids the sensor area, it would get into the engine unnoticed (i.e. with incorrect fueling to match).
Leave the flow straightener in place.

| I've removed mine before and can confirm it WILL set codes. Specifically MAF Flow too High. So back in it went. It only took a very short trip to get the MIL and surged and bucked under boost. |

Wow, I can't believe I was even close. I guess that degree was worth it.
