Besides going CF, getting lighter wheels, and gutting spare tire and seats. Are their any other tricks to do to kill some weight without completely gutting the car and making it looked strip down.
Basically i still want my interior to look good but loose weight at the same time.

Anything i don't know about, or do i basically have it down?

Yeah i think i remember somebody wanted to carbon fiber it. That would be awesome but way expensive lol

Anybody got anything else

Remove A/C
Remove all ventilation under the dash
Remove spare tire
Remove everything under the cargo cover
CF hood/hatch/roof
16" RPF1
Shove finger down throat

Btw, your system alone weighs as much as all this stuff.

Mount your battery in the trunk.

I'd assume the new aluminum radiator is lighter.

Brake rotors.

Relocating the battery adds weight, it doesn't reduce weight due to the fact that you need to add two beefy wires to run to the rear of the car.

That can actually help a lot in some cases...I've lost over 100 pounds since buying my tC, no joke!

Yeah my system weighs around 100 pounds but i love it and the box size is perfect for the great sound. I think im gonna try removing everything under the cargo cover

Odyssey brand battery even with the thicker cables will save some weight. Not to mention it takes some of the weight off the front of the car. My battery weighs around 14lbs.

Lightweight flywheel will save you some rotational mass. Not everyone agrees on them but light weight pulley set will also help a bit.

i agree with carbonxe that it adds weight because of the wires, but yet again you're not dragging the car so reloating the battery to the back will help balance out the weight distribution a bit better. but to lose weight...


TAKE OUT:

passenger/back seats
back panels
carpet

REPLACE:

hood w/ cf
trunk w/cf
roof w/ cf
wheels w/ lighter/smaller ones
battery w/ lighter one

tube frame chasis


you can make the car 2200lbs if you want, but that's some bank...

Just remember the more interior pieces you take out, the louder it will be inside. With no seats, rear panels, or hatch panels freeway driving is almost unbearable if you have a non-OEM exhaust.

Yeah i was thinking about taking out the baqck seat but i always have people back there so im gonna keep it, ditch the spare and all the crap under the cargo and maybe soon replace some stuff with carbon fiber

Mount your battery in the trunk.

Do you know why people move the battery to the trunk? And why you never see it done in a FWD car?

TRACTION

The battery's weight is used to help put weight over the drive wheels to aid in traction. Which in most cases is a much bigger problem than actual weight reduction.

Are you trying to get a better E/T on your drag time? If so, don't worry about pulling seats out and all that other nonsense, it is all minimal to begin with. Instead, invest in a LSD, 15" rims and drag slicks for the front. This will help the minimal power get planted to the ground rather than spinning your tires or the lovely case of wheel hop. (also might want to look into poly motor mounts as well as an engine damper)

a LSD is totaly different then weight reduction. Yes i understand what u mean with traction and it helps take off. But that only helps though your first 2 maybe 3 gears if you have the power and thats IT. It helps put power to the ground. Were weight reduction lightens up the car. Less weight = higher speed, acceleration and better aerodynamics.
If you match a tc with a LSD vs the same tc without one and full weight reduction which one do you think will win. :eyebrow:

in a drag race? 1/8 and 1/4 mile? The tc with proper traction wins. Trust me, I know from experience.

You can have the lightest tC on the forums, but if you can't hook up, suddenly your go-fast diet doesn't mean crap. Unfortunately, most things you can do to lighten your tC will adversly effect another aspect of it, appearance, audio quality, interior noise levels, practical use, whatever. If you want to keep it appearing stock, I've seen an old school charger that had drilled 2" holes into whatever inconspicuous spot in the sheet metal (under the doors, in the jams, under practically every interior panel). Granted, he also used a lot of fiberglass body panels and had no system and just a few interior panels in the car. Just food for thought.

Well if its stock most of the weight is taken out of the back and since its a front wheel drive car all the weight in the front is still the same so i would believe that traction control wouldnt be that much of a difference

You lose a lot of traction with stock set up. And you get A LOT of wheel hop. You can spin almost all the way through 2nd on stock tires and now power mods. And guess what that does for your E/T? I know you THINK weight reduction will help, but the truth is weight reduction only comes in handy when you start to run under 10 sec 1/4's and hundreths of a second comes into play. Cause really, that's all you're gonna gain from gutting your ride. focus on your R/T and hooking up and you'll be surprised at how much you knock off your E/T...

You can be light as a feather and have 1000hp, but it all means nothing if u can't put it to the ground.

that sub ur running is also draining power away from the battery and that definitely doesn't help. Might as well have ur a/c on full blast while trying to race.

didnt know that. even when its not on?? isnt their like an equilzer or something i can buy that helps it not take up all the power out of my battery

here's what u need to figure out. U are either gonna be a show car or a race car. ha ha there is no in between. If u wanna race then ur not gonna look good for the most part. If u wanna show then ur gonna have to add weight.

I think the rule of thumb is for every 100 lbs u remove u gain like .01th's of a second.

U need to work on getting the power to the ground. Like u said the LSD would help with all the way through the 3rd gear. well here's a secret, the tC is ALL low end torque which means we are better at launches. so u need to take advantage of that and try and create as much distance from the other guy in the start so that he will have to catch u at the end.

I would look into getting atleast a cold air intake and axleback exhaust. it would at least give u a few extra HP and better throttle response. good tires and lighter wheels would help too.

lol yeah sorry to say but i kind of am going for the in between look. I like my cars realllyy clean but fast too. I definetly wouldnt trade my system for anything and take it out i get plenty of comments on it.

The reason i was asking about the whole weight reduction thing is because i raced my buddys honda ... accord i think? And lost big time :tap: Im stock and i think he was too and he was running an automatic???!! I was like what the f*ck!! Maybe i should cut some weight on this b*tch lol

they have higher and faster reving engines. plus his accord is prolly lighter. hell our long doors weigh as much as those whole cars. ha ha

Learn one thing quickly. Tc's are slow.

You will get beat by almost EVERYthing. It takes a lot of time and money to make it respectable, not fast, but respectable.

So does that mean if we removed 2000 lbs of weight, we'd only gain .2 seconds?
I can't imagine that being accurate.

It isn't, well not entirely.

Acceleration deals with the ratio of power to weight over time. The more weight you start to shed the less time it takes to accelerate, but in each specific case the equation reaches a crescendo where the time it takes to accelerate begins to decline exponentially. In the case of the daily driver it is pointless to try and reach that crescendo because to reap the benefits and see any significant decline in time you will have to whittle your car down to something resembling a tin can.

Of course there is. The original version of the PTuning tC was a show/race car. They got laughed at on the track for it.

Show and Race is possible, it just takes A LOT of money, and A LOT of custom work.

thats me, just some boltons and took everything from the two front seats back out of the car. I want to see someone run that with just more traction. In truth both WILL HELP. Something you should think about is the more weight you need moved, the more traction it takes to get it going. If I didnot just have my little girl I would still have every thing out of my car, but yes it does get louder in there from the road. I got my car down to 2890 with me in it( 235lbs for me), you will see a lower et from it.

I dont know if you know this or not but your r/t has nothing to do with yor overall e/t, the clock starts when you start to move not when the light turns green. The r/t is how long it takes you to move, once you move thats starts you e/t.
thats just my two cents.
