few things.. first vid you said one amp.. second vid you have two amps..

why they want to waste money to make it go fast then more to make it go slow? if they wanted to make it loud add some glass packs to the exhaust..

haha. shouldn't have said that

you're telling me mechman shouldn't be doing this project to promote their product? you obviously don't see the appeal of "best of both worlds." have you ever been in a fast car? yeah maybe a civic with some fat friend sitting down in the back seat. bet even that car wasn't noticeably slower. you don't have any fat friends? then it's probably you.

that's ~400 pounds of stereo equipment (i'm guestimating here.. feel free to check my math) to over 700 horsepower. i think those horsies are still going to do what the owner wants them to do regardless of what is in the back. he's gonna have some ****** tunes to listen to while melting tires

i don't see how my wattage has anything to do with my knowledge of cars.. but i see how your years of autoerotic asphyxiation has clouded your judgement. like i said, leave the car talk to the big boys

its not just how much its where.. all the weight in the back will throw the balance way off.. most of us don't car as we are trying to go fast.. not to say it had the best handling anyways its a mustang but still..

and when you are trying to not sound like a 5 yr old its good to keep the retard lingo down.. besides you are younger than me retard

and you're living proof age does not = wisdom. if he was going for easy and perfect weight distribution he wouldn't have a fox body. they are street cars and they handle fine for what they are. if he wanted to put all that work into a perfect 50/50 distribution with a fox body he wouldn't have a hatchback.

you're angry because you don't understand the things i say. i said you whacked off with a noose around your neck and went into a coma. when you came to you weren't as sharp as you were before. people are allowed to be slow without being retarded

i'll be looking for updates soon so hurry! :)

I understand everything you say and that you have some homoerotic desires to whack it with a noose and you are projecting you behaviors on others to cover up for your own weird actions. and it doesn't need to be perfect but adding all that weight to the back will throw it even more out of proportion.

and wisdom is what you bring up.. let me know when you can figure out what mdf is instead of particle board.. blame the guy at menards.. but you saw it before you paid...

We were planning to use a warden originally, but it was brought to my attention that the gap is probably a little tight to play music on one for extended periods. The first vid was shot before we made the change.

5,000 watts should be fine for very short demos and burps. Input voltage and gains will be kept very low so that nothing has to be overstressed. Just because we have that much power available doesn't mean we have to use it all the time.



few things.. first vid you said one amp.. second vid you have two amps..

why they want to waste money to make it go fast then more to make it go slow? if they wanted to make it loud add some glass packs to the exhaust..

Originally we were going to run one large amp, but it wasn't available in time to make the show. These videos where shot across a two week period, and sometimes plans have to change to accommodate conditions.

The car already runs mid 10's on DOT approved tires, and is easily capable of 9's on race gas. In order to meet the minimum weight requirements for some local racing classes, and to run conventional street tire shootouts, we would have to put at least 200 lbs of ballast into the back of the car anyway. Basically we opted to install a functional audio system, instead of bolting steel weights in the rear bumper. It's a stock style suspension drag car setup for radials, not a road race car. We want as much of the weight in the rear as possible.

Here's a video of it on street tires against a 2003 Supercharged Cobra. It has 220 lbs of ballast in the back. No transbrake, rolling off the line just above idle:

YouTube - 2003 Cobra Terminator vs. Turbo foxbody (http://www.youtube.com/watch?v=yAuwj2ctR8g)

...and it's already an open 4" downpipe, so the exhaust note isn't going to get any louder. Maybe you might put glasspacks on your sweet ride, but around here glasspacks are reserved for flatbed farm trucks and redneck '79 transams.

If I remember correctly every 100lbs accounts for .1 of sec which is kinda of a lot at that level of racing. A plus of the build is having more wieght over the rear tires to help them hook to the track. You can say its a win win situation.

Uh what? The extra weight in the rear over the rear tires will allow the tires to hook up better.

I take it you've never seen a car do a wheelie? Drag cars intentionally have soft springs up front and most people will also remove the front sway bar to help transfer the cars weight to the rear causing ****** handling but a consisent hard launch.

Keep the videos comin mechman.

MECHMAN
04-12-2010, 11:35 AM
When we run our hard tire class, we are limited to a 300 treadwear, regular radial tire. (not a drag radial) I have added as much as 250 lbs ballast to the back of the car, and the more weight I added, the faster I could ramp in the boost, and the lower the ET got. I estimate that this build will add about 350 lbs to the rear of the vehicle, so we will see what that does for ET.

I'm still doing some smoothing to the instide of the box, and the port exits. We will be installing the box and wiring it on Wednesday. I feel that the SPL gods will smile on this build :)

We still have a lot more smoothing to do, but hopefully we should have the lid on and the box mounted today.

Here's the mockup of the sub. It barely clears the spare tire well by 1/2 and inch, and the rear of the surround clears the back of the hatch by about 2". Once I install the amps and batteries on either side of the box, there should be hardly any air space except for the "wedge" of airspace above the hatch.

progress so far has been a little slow, had to wrap up the bathroom remodel in my house, AND we broke and axle over the weekend, so know I have to deal with that. The next vids should be of the windshield flexing....

Basically we just have to swap out the alternator, finish covering the box with vinyl, and we will be ready to rock. We opted to go with two D1400 XS power 14 volt batteries instead of just one, they look more symmetrical and fit in perfect little pockets on either side of the box.

MECHMAN
04-19-2010, 11:51 PM
We did a quick amp test with just one amp, on one coil, just to verify that the amps would run at 17 volts after we modded the board. We didn't even have the sub screwed down, and the windshield was flexing, LOL. I expect good things.

The box has two baffle boards that make up twin 8"x8" square ports firing into the seats. All the corners inside the box and ports have been rounded and smoothed, and 2" pipe was used to make rounded inner flanges for the ports that double as box reinforcement to support the sub.

not really the baffle.. was talking about where the sub sits. is that only one piece of wood? is there any other bracing inside the box

MECHMAN
04-20-2010, 10:48 AM
2" pipe was used to make rounded inner flanges for the ports that double as box reinforcement to support the sub.

Also, that is marine birch ply, much more rigid than MDF. There is only about a 6" span of unsupported board all the way around the sub, so it is PLENTY strong. We used birch so that we wouldn't have to make the box so heavy with multiple layers of MDF.

I am going to do a flush mount trim plate, but just for looks, not because it needs the strength.

I just played it with the car turned off. (no alternator) I tried playing some Jeezy on a CD, but it would just skip at about half volume. I plugged in my Iphone and played "Put On" and the fluorescent lights in my shop started shorting out and flickering from the Vibration. Still needs a little tweeking but we think its definitely breaking 150 db. I would have made a vid, but I had to use my phone to play the song, LOL. I will post one up tomorrow.

Regarding the choice of the Death Penalty over the Warden-

I easily could have afforded either one. I gave Nick (the owner of Incriminator) my specs and what the general use would be, and he recommended that I go with the Death Penalty. I would think that he, if anyone, would know.

Sweet! I was building mine for Meca boom & zoom, but there don't seem to be any events on the schedule?

I'm going to try and get some events going, I know we could do one at I40 dragway in Crossvile TN.

Maybe if I get real cocky and start calling people out, it will develop enough interest to get some B&Z events on the Meca schedule.

I'm pretty confident nobody in the country would beat my combined score, so lets find out!!

Did you not see the video link I posted, you can see just about the entire system in the video:

Here's a vid of it pulling up in the lanes at the show last weekend:

I am taking it to a local car show this weekend, so hopefully I will be able to get some good vids of demoing it for people and their reactions.
