I'm used to messing with my old LS1 where the spacer was a joke, so I didn't even think about TBI cars before I posted..........lol

I'm talking about cars like mine, which have individual fuel injectors in the cylinder heads, where swirling the air is doing nothing. I would agree that if you can swirl it with the fuel and air together, then gains are possible, but on my car there is no fuel anywhere near the throttle body, the air has to travel about 12" past the throttle body before it gets to the injectors, making a couple turns on the way, which would negate any effect swirling the air would have anyways.A simple misunderstanding of the type of "throttle body" you guys were talking about.

In old cars the spacers made a difference in fuel atomization, but in new fuel injection cars, they are almost worthless. They would work if they were swirling the air and fuel together, but swirled air is just that, swirled air, it does nothing to add horsepower. All fuel injected heads have a swirl damn built into them right at the intake valve, so that's where the fuel/air mixture gets swirled. Swirling air before it has to go through about 12" of intake runner on a fuel injected car really does nothing.

I have an Eclipse CD-8445 currently. I don't plan on getting rid of it any time soon, but need to add the cd changer because I can't turn my gains up at all on my bass or it skips.

My wife really didn't keep up with what I was doing to the R/T, but she decided to take it to the grocery store one day, and when she popped the trunk to put groceries in there, I heard about it, since she couldn't fit anything back there, and it actually had a pretty big trunk. She doesn't tell me I can't do anything, because she knows I'll just do it anyway.

Wow, can't believe I missed this one. I'm Richard, and have been into car audio for 16 years. I used to compete in IASCA from 1990-1992 in the 0-50 watt class using a pair of Autotek 7050XX's run down to .5 ohms and was fairly successful back then. Got out of the competition scene for a long time, got back into DB Drag for a season and realized I like music too much to build a true SPL car, which leaves me where I'm at today.We are currently trying to build the loudest single 12" daily driver car on the face of the planet, and doing it all from a trunk car just to be different. We are doing fairly well right now with a single MTX 9512, hitting 146.2 legal on the dash, but we're giving the sub all it can handle for daily driving, and need to upgrade both the sub and the power. Current plans are to beef up the electrical system, deaden the entire car immensly, and shoot for 150. I think the next woofer will most likely be a TC Sounds LMS-5400 in a rear loaded horn design, but that's still up in the air. I look forward to sharing my build and showing exactly what we can do to hit 150 with a single 12.

I hope you're ready to copy, because I have a ton of "old school" stuff. I don't call it old school though, it's just stuff I jammed in High School... Afrika Bambaata - Planet Rock Chubb Rock - Treat Em Right Kid Sensation - Rollin' Cybotron - Cosmic Cars Anything by Dana Dane is cool Das EFX - They want EFX Digible Planets-The rebirth of slick Heavy D - Now that We've found love LL Cool J - Boomin System N 2 Deep - Back to the Hotel Getto Boyz - Chuckie and My mind is playing tricks on me Special Ed - I've got it made UTFO - Roxanne Roxanne Mix A Lot - My Posse's on Broadway, My Hoopty, and Rippin' Slick Rick- Hey Young World Whistle - We're only Buggin' Whodini - The Freaks Come Out at Night Masta Ace Incorporated - Born to Roll That should get you started on Old School at least..........

If you don't have any future plans for that old AudioControl DQS, let me know

Damn Steve, you and I must be the same age, and I get looked at funny when I play old stuff.

That comes from the mentality that it's only cool if it's loud outside the vehicle. I run into that everyday. My new setup hit 146 on the TL, but my neighbors weren't impressed because, I quote, "It doesn't seem any louder from out here". And then they looked at me funny when I said I didn't care what it sounded like on the outside of the car.

With one of my old boxes, I hit 136.9 with a single 12, everything being the same, we moved the box back to about 6" from the back of the trunk and then hit 138.6 just from moving the box around.

In a trunk, firing the woofer and port to the rear has been the loudest and best sounding for me. You could probably get louder if you took the rear seat cushion out and actually sealed the box from the trunk, but I'm always a fan of stealth, so I say just run a lot of power to the MTs and fire them to the back and put a lot of sound deadening in the trunk.

Pete just sent me an awesome looking folded horn design, and I was wondering how much of a gain or loss you'd usually end up with over a folded horn over a standard ported box for a loud street beater, not tones.

Nope, just big, cheap, crappy sounding horn tweeters.........

Around here, they mount huge horn tweeters in the grille, I still don't understand it.
