Lighter and smaller rims make a big difference, as does tire weight. Yes some tires are heavier.

removing all those bumpers/hood/windshield/fender things would create more drag, probably outweighing the benifits. only maybe going w/out hood (for the cooling effect) would create more benefit than loss.

what are cam sprockets?


If we remove the muffler how terrible is the sound?

I think I can loose weight so I could add that to own personal list. It wouldn't hurt if I lost 15 pounds.

cam gears that are on the cam and turn the timing belt. That's not really an issue here. Well I've tried to reduce weight, but I'm not willing to give up a nice sounding stereo or body kit. Muffler hardly weighs anything. Maybe 5-10lbs stock. I got new seats, but they're only 5lbs lighter.

I was looking at these seats today. Only 11.8lbs w/out brackets. Comes with universal side mount brackets. Might be a beiatch to install? But with brackets they should be about 15-20lbs less than stock. Now if I can find a nice carbon fiber hood to save another 20lbs.

Hey guys we shouldn't negate any idea. We are making a list lets see how lean the car can get. If we get the car to 2100-2200 pounds its a pretty astonishing weight reduction. Then people can view the list and see which mods are good for them and whether weight reduction is viable and cost effective. It is part of tunning. Its one of the optiosn we should take seriously since its not so easy to mod our engines.

i dont think anyone specifically said to get a lighter flywheel. that would help out way better than weight reduction especially in 1st and 2nd gear. you might notice a little difference in 3rd, but thats about it. fidanza makes 7.5 lb flywheel for our cars...i am about to get one. all i know is with that your trap speed will be higher and you can launch higher cause of the less rotating mass. it wont build as much interia as a stock flywheel would do...so it would be a little harder to break them losse. there are so many products like lighter rims, brakes, drivetrain and engine internals that can help you get more of your cars power to the wheels. you lose a lot of your hp and tq through that stuff....why havent a lot of people figured this out. this is just stuff i felt like got left out. later.

Yeah I'm currently working on a crazy idea I had.
I'm gonna try to power my alternator with a dc motor, a pulley and a seperate battery. This would eliminate the need for the crank pulley and alternator/AC belt. The problem is if I remove the crank pulley I need to put something real light and probally rubber that will absorb harmonics so I don't screw things up. If anything I'll at least get rid of the alternator/AC belt and free up some hp. I'm still researching everything.

Rotational weight is worth around 70% more then static weight.... so, Have your Gears drilled, get a light fly wheel, Find the lightest wheels you can,Find some light weight axles,Ect ect ect... Basically lighten any thing the engine has to get to rotate.

Will a light weight flywheel have any adverse effects on the car, or is it just better overall?

Whick axles can we put on our cars?

The problem with a light fly wheel is that you may have trouble getting the car moving from a standstill.

what the stock "heavy" fly wheel gives you is Inertia. this inertia helps get the car moving because it allows the fly wheel to have enough force to grab the clutch and not instantly stop and stall the engine.. a light fly wheel doesnt have this, so it forces you to either feather the clutch more, or rev to a Higher RPM to get the car to not die when you engage the clutch. once the car is moving you'll have no problems though. This is why Really light flywheels are ushually reserved for Track use, where saling the car isnt really a big deal..

I seen a video of dude with a modded GTI and his car stalled twice once on the start and once when while he coming to a stop. He might of had a light flywheel.

Whats the bad part about drilling the gears?

They may brake sooner, your removing metal and reducing their structrual integrity. You'll need to have them balanced too..

ooo weight reduction!!! my favorite

Lets see

you can remove your A/C compressor, core and piping. On my mazda this was around 70 lbs. Also there may be a bracket that holds the compressor to the engine block.

Lexan windows, anyone thats had to pick up the rear glass of our cars knows what im talking about. Lots of weight there.

Lighter rims would really help

removing the back seat wont help too much, its basically a big chunk of foam.

But i think youd be hard pressed to get the EX (2600 lbs) under 2100 lbs without really taking a hit in the comfort department.

Hey everyone check this thread out
http://www.7thgencivic.com/forums/sh...d.php?t=183085

The guy has a dyno chart of his performance improvements with a lightened flywheel and performance clutch. He says his car runs fine, but I think it sounds too good to be true, he dynoed 125 WHP.

Let me know your input guys.

No they're different. Check the wheels forum for a sticky that has the weights. I think the stock steelies are around 18lbs, and the 2000 Si alloys weigh a few lbs less. Lighter, smaller rims = faster acceleration.

Btw, the LX has 14 inch wheels I believe, which is even better. The EX has 15 inch wheels.
