Relocated Mass air sensor lower too the ground

[1986LX2002]

Was at a local car show and saw a 91Gt with tons of goodies on it and the guy relocated his mass air unit lower to the ground. He had a Aftermarket cold air unit but the sensor was mounted 4" above the cone'd air filter. I asked him what was up with that and he said because the air is denser lower to the "i knew this already just wanted to see what he'd say" He also said he gained more seat of the pants feel and that the throttle response is a bit crisper. Knew it wouldnt give you a ton of power but ever lil bit helps he seemed to know what he was doing at least i hope lol afterall it turned out he worked for ford as a mechanic "but that isnt saying much" Anyone else seen this on other cars or have done it?

true, the air is more dense closer to the ground compared to 1000 ft in the air. but honestly, how much more dense is it? maybe the longer tube to the throttle created more velocity or something, but the air being more dense is kinda sketchy

Yeah it's not like he gained a ton of power or anything. The way i see it is that its just another thing to get a lil more power even if you dont get any. Here in Arizona though i wish we had more cold and denser air, during the summers here its terrible. Its a night and day difference between performance when the season changes. We basically have only summer and fall. It never gets "cold" here like other places.

I can see if the air pickup was lower to the groung but what difference does it make where the MAF sensor is located? I'm with ECU5.0 on being a bit skeptical about the gain. Pulling air into the throttle body from perhaps a 12 inch difference in altitude wouldn't produce a noticable gain. About the only thing I've seen that really has produced measurable dyno results is drawing cold air vs. hot air from the engine bay. Even the ram air kits that I've seen (read) about being tested produces negligible results where a positive displacement supercharger or turbo was not being used. The centrifigals seemed to care not if ram air was used or wasn't.

Forget to mention the fab'd up his own ram air kit. He took out the fogs and made a sheetmetal style box behind the passenger side which was his intake basically and then went into a cone style filter than after that was the mass sensor which then went into i'm assuming what was left of a bbk cold air intake tube. He probably scoped up plenty of air with his box "looked pretty nice btw" because it was completely enclosed. But yeah i'm with you guys there's probably not a difference, its the mind over matter type of thing probably just made him feel good knowing what he accomplished.

the actual location of the MAF meter in the intake tubing makes no difference whatsoever except for one thing. The air is supposed to pass through the meter as straight and steady as possible, to get the most accurate measurement of the incoming air. If the open end of the intake draws in air from a spot that is "colder" or "denser", then the air farther up the intake tube will be the same. It might heat up a little, but it wouldn't be much. Moving the MAF meter down the intake tube to get it away from the heat of the engine will only richen up your a/f mixture. If that makes more power, it's because your tune was off and you were lean. If your car was in tune and then you moved your MAF meter, if anything you'd go a little rich and lose power.
