Intake resonator on VG - What for?
I have a 94 Max GXE, and the intake tube after the air filter has a black box attached to it, with a whole in the tube that leads into it, but the box itself is sealed. I've read that it suposed to reduce the sound. So I cut my box off and pluged the whole with a rubber cork. I didn't notice any difference in noise, and I think the car became a little weaker. I have a stock intake with a regular air filter. Does that box affect performance in any way?
If I put a cone filter on, will it change the sound?

p.s. It's probably a stupid Q, but what's WOT?

how did you "cut it off"?? and if you didn't reseal it properly you are most likely having an airleak thus a possible loss in power!

do a search on google for helmholtz resonator and research a bit for yourselves. automotive applications include removing loud engine resonances at certain RPM and to smooth out power peaks and dips because the intake/exhaust is tuned over that band of frequencies.

I cut off half of the box off, and sealed the whole that came into the box with a rubber cork. How would having an airleak cause power loss? It should be the opposite instead, because you have more air comming in, not considering the air would be dirty.

plugging the hole would be a bad thing.... the tube that runs out underneath it is a sorta stock "cold air intake" think. It adds some performance, so plugging the hole would hurt. it's also not that thing which really takes away most of the sound. If you just want more sound, get a CHEAP pop charger(K&N), but don't spend to much. I bought a $130 pop charger(Jim wolf), but didn't realize that I could have gotten CAI for $150!(also got a 2nd intake, a k&N filter for $45 that I can't use, so I'm a lil screwed).
Save up and get an actual CAI, it'll probably be the best to aim for. If you want to spare money, there's a way of making an adapter out of your stock air box(kinda risky IMHO), and you could do that for as cheap as those little neon paper filters at autozone. But a K&N would be better.

I did a search on that and it gave me a whole bunch of formulas for sound and air
I'm not that intelegent, so can you please explain in simple tearms what you just said above. "smoth out power peaks" is that in sound or performance? will the resonator affect my performance - is it better to have it on or off {not considering sound polution}?

OK people what in the world is going on sheesh...Do not leave the empty hole un plugged...dont listen to doomtoo. Period end of sentence. It will draw in dirty air that will couse engine problems and the hole is AFTER the MAF meter so the engine will be getting more air in than it is reading which will cause problems.
It will not hurt to have the resinator off and the hole plugged. I have done the same thing.
