Default Any gains by porting MAF??

Do you think I would see any gains with porting it, I got a lot of mods on the car and this is the one thing I haven't done yet... <img src="gr_stretch.gif" border="0">

My major mods are

Cam
Headers
LS6 intake (stock)
lid, free ram air
catback

I have an MAFT so I would be able to tune it...I would just like to know if it would be worth it.. <img src="gr_stretch.gif" border="0">

The 98s usually gain the most with ported MAFs, but the newer ones tend to have more problems with pinging than anything else. Although if you have a MAFT to tune it, then you should be ok. Give it a try, my MAF porting page is still around:

My honest opinion would be that you should just remove the screen and leave the rest alone.

Joe Prince showed me the difference in flow of a descreened maf and a ported maf and it was very minimal, less than 10 cfm.

I picked up a ton of tq and hp by adding IRS 75mm bookends on my 2000 WS6. Gained from timing increase, not from airflow. Gained 4 degrees of timing across the board. Your results may vary.

Here's the dyno sheet: www.converter.cc/ported_maf_gains.htm

The results are what im afraid of, cause I won't be able to get on a dyno right away, I'm sure If I do it I will be able to tell with my AFR gauge.. <img src="gr_stretch.gif" border="0">

We will see what happens.. <img src="gr_stretch.gif" border="0">
