The car you see in the link has an naturally aspirated b16a engine, I would like to increase the performance and keep it naturally aspirated. I have already upgraded the intake, exhaust, cams, hondata tuned, coil overs, water meth kit etc.

Im now thinking of weight reduction using carbon fiber parts. Would this add any significant performance to the car.

Of course it would. The lighter your chassis is, the more powerful you engine will feel. Your acceleration, braking, fuel economy will all improve.

Negligible weight savings.

people still swap out for CF parts? What year is this? How long have I been sleeping?

yea it will be lighter its not as ridgid though so you loose some stiffness. also if the car is not garage kept then i would get some heavy rubbing compound and a 6" buffer to buff out the oxidation from the rain and weather.

Smaller ,lighter wheels and slap on a carbon fiber hood.Nice civic btw.

oh yea the lighter the car the less the engine has to work to get the car up to speed. its like if you were to run 100 ft with a 100lb vest on and then doing it with a 50lb vest, witch do you think would be faster?. the only downside to carbon fiber is depending on the are your at, like here in ct having a carbon fiber hood is a lot harder to take care of to as if you were in cali or fl, cause of the constant differences in seasons, winter cause carbon fiber to crack if not taken care of.

I highly doubt it will be anything significant.

There's better places to put the money for performance. If you're looking at from aesthetics point, do what you like.

It is not significant for performance. Too many threads asking about weight savings and all of them barely remove any significant weight. I don't know how much weight you people think you'll actually be getting rid of. It's negligible.

Fliptard

The only way I see wieght doing anything is if you gut the interior, carbon hood, lighter wheels, and get rid of everything else that has no real use/need. Then maybe it would be worth it. But then you lose everything you took off.

If you mean totally gutting it, removing the heater core, etc, then yes. If just rear seats, panels, not so much.

Shedding some weight works wonders on hondas due to the power to weight ratio.

So back seats removed equate to about 10 horsepower then?

Fibercation

get quality lightweight wheels

98civdx

That's what it's starting to sound like.

Back seats weigh what? 10 pounds combined.

What about stickers then?
Those add 3-5 each but thats only for one color ones.
Two colors and above start a 7hp and go up with size

People, it's an extremehonda-R. It's no regular ex/si. Nothing is too extreme. So why are we flaming?

If you're looking to shed weight, listen to Fibercation. The reduction of rotating mass has the most significant effect on acceleration response. Wheel weight reduction has other positive effects too but I imagine the details aren't worth getting into seeing as grumblemarc as already pointed out that there are tons of threads relating to weight reduction and this probably isn't a dedicated race car that would have a tuned suspension.

CX-Adam

Also, it's a nice looking car. Good work.

No Flaming intended here.
He should leave it as is, and leave the weight reduction alone.
That car with the right suspension upgrades, wheels should handle great.
Feeling power from a weight reduction on a street car is negligable like Marc said.
He wont even notice it.
Carbon fiber doesnt wear well unless you have it out of the elements all the time.
Sun, cold its just tears it up.
First you see the clear coat go, then cracks etc.
Carbon fiber is best suited for the track because track cars dont sit outside in the elements.

viciousjames

Living in florida carbon fiber gets alot of sun damage. Most people get it for the looks and after a year it looks like crap. Unless you take good care of it. Which most people dont. Our hoods are already light. Unless its a track car i wouldnt bother. I have a sc300 and that hood is heavy as f@#k lol

98civdx

Most of the parts on these cars are already quite light.

PerfectionIsKey

Unless the car is going to be a Trailer queen just leave the Carbon fiber parts alone. Leave the "Blingy" and "Eye-candy" parts for last. Just throw in a couple "Eye candies" here and there. Like someone you will see and use on a daily basis as in a Steering wheel, shift boot and **** ect. Carbon fiber parts are way to expensive for a street car.
