So I was looking at 8thgencivic forums and found a thread about how people were disconnecting their resonator chamber from their intake. Basically removing the tubing from the chamber to the air filter box. It seemed like a good idea since the radiator hose is appox. two inches from the air-box, plus the tranny is right bleow it so water and such is not likely to get up in there.
Needless to say I gave it a try. I was goin to test any FE improvements/ decreases by the half tank. But then my testing went somewhat wrong. I found that below around 2.5krpm the engine sounds pretty normal. 2500rpms is right around my cut off limit for forcing the auto to shift unless I'm going up a hill or something. Out of curiousity I decided to gun it, since I essentially created a short ram intake. Well above 3000rpms it sounds like somebody let the demon out of my car.
Long story short I've had a bit of a lead foot lately. Although I'm still managing 30mpg. I'll have to see how it does on the highway. I'm thinking that a scangauge might help with the discipline, however that sound is addicting.
I was working on my friend's 7th gen civic and we left the resonator off to test drive it, after first I thought we broke something, it was crazy, anyway, he's never put it back on (I have mine blocked cuz I can't get it out,
Oh yeah, I could hear my friend pulling out of his parking space after school from 150 yards away, it sounds beastly. I'm guessing they started making them really loud and muffling them so that people could get their "loud intake" jollies easily.
Well so far it's gone down a lot since I can't keep my foot off the gas. I can't say that I would even be able to detect any changes anyway cause i have to measure by the half take. My FE usually fluctuates +- 1-2mpg every time I fill up. Until I get a scangauge there's no telling what it does to the FE.
I remember when I put the Injen WAI on my altima. It took out 2 resonators and it made a straght pipe into the Throttle body. it souded mean like crazy and you could hear the car from a mile away. Anyway... Whenever I went into tunnels or under freeways and saw ricers I would have some fun with them and gun it a little. They would look all paranoid searching for a V8 or V10 car. The look on their face was priceless when I drove by. I remember one time when I was into saving fuel and I was on a 1 lane road doing the speed limit when an integra wanted to go around me. I gunned it a little and he got back in line real quick. The noise was scary, forget about adding stickers adding 50hp, this thing made the engine sound like it had 500hp.
