thanks alot

 

My 2cents. GM spend more money than you would think designing the MAF sensors. If removing the screen would add hp they would of done it, they were competing with Ford and Dodge. A shop my company works with on a regular basis, House of Boost, leaves the stock MAF in when they turbo a GM, so I doubt it's restrictive. They know what they're doing they've done many GM cars and trucks, turbo and supercharged.

The coolant bypass, I'm passing on cause I live in KC and it'll be in the single digits tonight. The air box, I'll think about. I'm going to look into making a ram air.

Just something to think about.

 

Man, I've really got to say, honestly, this "mod" is NOT adviseable.
Won't get you anything except a burnt trans. I'm not hating, but I just think other people should realize before more try it out unknowingly!

 

That's been beaten into the ground too much to even argue about anymore.

 

I am thinking of doing the same, I was under the impression that it was a silencer but the water trap sounds legit too. I wanted to do it because it seems that the down scoupe would cause a pressure drop or a vacuum effect. I may be wrong.

 

hope this isnt a repeat, my apologies if so but its worth sharing..
guess this mod cost me 14 bucks versus 300 anywhere else.
i cut a round hole in the bottom of my existing factory airbox (4 inches)..went to Lowes and purchased a 4 inch drain pipe with a scoope extension(to poke out the front spoiler--you have to remove tow hook)
then i removed the steel plate that the airbox sits on--leave it out.
poke the pipe up thru the bottom of airbox..put it all together with a lil duct tape and zip ties, and oh yeah the filter is K&N.
Lets in massive amounts of air, ill just have to clean my filter more often.
Also just changed out Fuel filter, and next on list is spark plugs..

 

how in the world can the removal of a maf screen burn a trans????!!!!

 

I just moved to Germany, am waiting on my truck to ge here, just gt a cai and programmer from rpmoutlet.com, seem to have very good packages. Can't wait to take my 07 Z71 5.3 w/ flowmaster series 40, predator programer, S&B CAI out n the autobahn. Can't wait to blast those Europeans with obnoxiously loud American V8!!! LOL

And plan on de-screening te MAF... I had a 96 SS Camaro with Complete topend redone, port and polished, bigger valves, rollr rockers, .525 inch lift cam. Replaced my stock MAF with a Granitelli (which came with no screen in it) and could tell huge differences fro the MAF alone.

 

The screen is there to flow air across the sensors evenly. Removal will create turbulence and cause misreadings on the hot wires. The MAF, TPS, and MAP sensors all work in conjuction to help the computer calculate readings in according for the right AIR/FUEL mixture and load on the engine. Calculating the load means what gear the transmission should use. Therefore one sensor off will affect the whole chain. I did it to my 01 and guess what???? The transmission shifted bad for a day and then eventually burned up!! So if you wanna learn the hard way then go ahead. Only way is to get an aftermarket MAF which does not require a screen. And also descreening will not yeild extra HP. More air does not give more power alone. More air means more fuel is needed. In those cases would work better when a bigger cam is added.

 

Air Box Mod???? Im wondering if anybody noticed a big M.P.G. savings? Im getting 15 now with my 2500 HD. If I could gain 1-2 more Id be super happy.
