air box mod?

[JDCAMARO99]

Question......I was up at the track last night and a guy was telling me to take my air lid off and jigsaw away some of the plastic on the air filter holder. he was saying the airflow is so limited with it coming in through the ram air. He said i'd pick up more air from under the car. He also told me to take the screen out of my MAF. He told me that I would pick up 10 to 15 hp. Is this accurate? I feel like the guy was being a little carried away with this. And, I certainly don't want to mess up my car by messing around with stuff like this if it's not going to help.

I have 2001 Camaro SS with LT's, high flow cats, y pipe, slp air lid, air bellow, dyno tune. I'm running consistent 12.9's. So if I do these mods, will it actually be worth it? And will I need to get a re-tune done? I really don't have another $400 to spend on another tune. Thanks for any feedback you guys may have.

Check this link out. I wouldn't mess with the MAF. When I did it years ago it started pining under full throttle loads. Went away after I replaced it with a new screened housing. The free ram air mod is good though.

Air box mod - I've done it and to say it gave 10-15 hp gain is It does give it a bump but not so much that you could say yeah, that's it. I still recommend doing it, just beware that filter changes or cleaning (if you used K&N type filter) will become more frequent. What the mod does is it takes an opening of about an inch and increases it to about 3-4" wide, letting the filter use more surface area. Think of it as an asthmatic kid breathing through a straw vs breathing normal.

MAF Descreening - I do not recommend doing this. Again very marginal gains and increase hazard to the MAF. Meaning if something blows through the filter that screen is the last line of defense for the MAF & engine. IIRC this is something that pro track drivers do that has crossed over to the street. Big different between the two is on the street it is easier to have something sucked up into the air intake. I once had a plastic bag sucked up into the filter.


No tuning mods needed. You will benefit more with a LS6 intake and to help lower your ET's some suspension mods like aftermarket LCA's and torque arm.

I haven't messed with the air box on our car at all. As posted, leave the MAF alone. Any attempted mods simply throw off its calibration and result in misreported airflow to the PCM. The stock MAF will hang in there all the way to about 500 hp.

The free ram air mod works.

Its even better if you add a(FTRA) Fast Toys Ram Air set up or the(SSRA) Super Sucker Ram Air.

The FTRA is stainless steel and sells for $169.00-199.00 and the SSRA is plastic and sells for $199.00-$249.00.

BTW don't mess with the MAF.

thanks man. good stuff. I think i'll do the air box mod and try it out. It looks like i'll keep the MAF intact.

Thanks for the info everyone. I've had this car for a couple of years and I'm still learning great tips on these. Awesome Awesome cars!!! Thanks again.

Sometimes even more than that

as other's have said....don't mess with your MAF. It's calibrated to have that screen there....that screen straightens the airflow across it. The only time you should mess with that is if you can get the car tuned for it so the calibration is correct. The airbox mod won't hurt anything, other than having a dirty filter way sooner, but if you do a FTRA or similar scoop avoid deep water. I've read a few times over the years of people sucking water into the motor going through deep water. Why the hell you would go through water that deep is beyond me but it's happened.
