I disagree with the suggestion that it is a "very bad idea". I do not believe it will cause harm to the engine or have a negative effect on performance. If that is what the orignial poster was suggesting.

IMO

 

Anyone else notice that those of us who take the time too understand how and why things function generally have very different opinions on things than catalogue modders do? We also tend to have very different results, like faster for less money.

 

blah blah blah....

i've been running for 5 years now with NO problems. i understand the dynamics and i also understand the design and why it's there....

i also understand that in 2004 GM removed it from the MAF themselves....so that apparently means it's not important. there are tons of other people here as well that have had no problems as well.

HOWEVER, there are some people who have had problems. and, if you decide to go cutting away at your MAF i have a stocker available...i'll cut you a 50% discount from factory....i'll only charge you 200 bucks. kidding, i'll sell for 40

edit: i did come a cross a 1' deep puddle of water one day and the MAF did get wet...car stalled, sprayed with ELECTRONICS cleaner and was done with it. car started fine and i'm still running that maf today. but i dont think that a screen or wing would have stopped steam from shorting the maf...or whatever it did.

 

I guess all the tuners who tell you not to port your MAF or put MAF ends on are talking out of their *** then....

 

The screen I see as a minor thing.
Porting or changing the ends I see as MAJOR and a bad thing. It can be retuned but with signifigant effort all for no gain because the stocker is not a restriction.

 

I recently installed a ported descreened MAF housing. Data logging before and after showed no negative results.

 

Just because you lack the knowledge and equipment to see the bad results does not mean they are not there.

The MAF can not accurately report airflow if you change the cross section and do not retune for it.

If you had a wideband and checked before and after WOT AFR you would see a difference. The O2s correct for a lot at part throttle.

 

You are correct. I am a catalogue modder who lacks the knowledge.

Have a nice day.

 

I know what you mean, I think part of whats going on here is that a lot of people have already removed the "screen" and really don't want to accept that it's not beneficial and reduces the accuracy of the MAF. The other half don't understand what going on with the sensors so there is no way to really explain it once you've explained it...

Also, it's illogical to infer that not noticing negative results implies the change is beneficial.

 

wow....double negative.

i still have no problems. nor did i see a reduction in fuel economy or in power/feel. it didnt do anything, but i'm not going to go switching things around unless i need to. i still have a stock maf though, and if i do have any problems with either i'll use the opposite

Installed the factory one today and took of the Granatelli one and cut .41 off my 0-60 time. This should make my 1/4 mile time drop over a 1/2 second. Not bad for 5 minutes work and $90. I spent 3000 on other mods and dropped a second, so this rocks.
