Hey guys, like the title says...

How much HP will it add?

Also, anyone with one, how does it feel?

 

Pros: much better throttle response, much faster revving.

Cons: possibly stalling in vacuum (turning with power steering and brakes in neutral, etc.), overrevving becomes much easier.

It won't add HP, but it might free up some .

yup, took the words right out of my mouth. if anything with a lightened flywheel you might get more HP to the ground.

 

Question:

Can I take my stock Flywheel.. and shave like 6 LBS from it?

will it be safe?

I know there like 17 lbs,
11 lbs is good I think..

 

probalby not

 

since you'll rev faster, itsn't it true you'll lose more rpms between shifts ?

what?

does someone have an answer to this?

 

if you shift like a granny, maybe.

 

well, to me a civic drops rpms fairly quick between shifts. granted my car is new to me and is stock, so no short shifter. buy my 95 mustang gt barely lost any momentum between shifts and it had a yardstick as a shifter

 

lol, I dont shift like a granny.........

i'm going to put a SI tranny in my car, so might as well put a lighter flywheel, and a new clutch.

Also for my D16 CRX, i'm also thinking about putting a lighter flywheel on that bitch.

Just need some info here. and nobody has it

 

it takes a little of getting used to..
shift like granny + lightened flywheel + 6 puck = not a good combo..

 

well i'm not getting a DRAG clutch, i'm getting a street clutch...

also i'm just going to shed off 6 lbs

 

I had the ACT streetlite in my HB with a B18b and that flywheel is 12.5 ish lbs. I noticed faster revs, losing rpm when shifting wasn't somthing that i noticed. If i could do it again i would try the prolite flywheel which is lighter. People that rode in the car commented on how fast it revved.

 

I'm new to Hondas myself, but on my Focus, I lost a full second off my 1/4 mi time with a lighter flywheel.

more details.. is it that it is harder for you to shift correctly?

 

No. Shifting wasn't the problem. It was launching. Because the flywheel was lighter, you'd launch and the engine would bog down because of it.

 

i had a comptech 8lbs flywheel, ACT MAXX pressure plate and clutchnet sprung 6 puck and i never had any problems what-so-ever launching. i actually launched a whole lot better than i did with a stock flywheel. the trick is feathering the clutch...you just have to get used to it. and to take full advantage of a lighter flywheel, try getting a short shifter. it really helps with the dropping revvs

 

I guess it varies from car to car.

 

Lightened flywheels WILL NOT show an increase in HP period. Not on a dyno, not anywhere.

They free up rotational mass allowing quicker rev matching, easier heel/toe and just better all around drivability.

There are a lot of rumors about lightweight flywheels. Personally between a lightweight flywheel, an improved final drive and a single drive crank pulley there are few and far mods that are as noticeable as these.

If you are into "street racin'" and dragging you may or may not like it. As you will probably not notice much of an increase in straight line acceleration. Once you are on a track it is a WORLD of difference. At least for me anyways.

and driver to driver.

 

I won't take that as an insult. It happens on every Focus. I know this to be a fact.

oh sorry, it wasn't meant as an insult...just trying to compare that driving styles vary as well.

Actually, it depends on the dyno. On a steady-state dyno, there will be no difference. But, on an inertia dyno, it can show an increase in HP numbers.

 

all pro's, no cons

revs faster, allows more power to reach teh ground, car feels more alive

they are one of hte first mods you should ever do

I can't agree 100%. While most of us would want at least a slightly-lightened flywheel, it isn't better for all driving conditions - especially if it gets really light.

Just as Twilight2ner said, the lighter it gets, the worse launches are. This is because when the flywheel gets spinning, it's holding all the inertia used to get the wheels spinning. When there is less weight behind it, then you need higher revs and better throttle control - especially if you have more traction (slicks) or heavy wheels.

From a physics standpoint, if you had a million-pound flywheel (and enough power to get it spinning), you could get to the end of the track just from launching and never touching the gas again (I'm sure it would even take you farther than that).

Also, with a lightened flywheel, you will notice a loss of momentum going up hills and less engine braking.

So, for dragging, it isn't necessarily what you want. For road racing, you probably want it lightened. For the street/track, you don't want it as light due to poor launchability.
