What are the pros and cons of using a lightened flywheel. I have found a few in the $200 range. I know that with going with a lightened one the engine will spin up faster and have less momentum. How does all of this effect the daily driving?

Thanks

 

I had lightened flywheels in both a D-series and my B-series motors. I live in San Francisco (read hills- big ones) and never had a problem in driveability. Throttle response was really improved. I also do open track events so it depends on what your looking for as the revs will drop off much sooner and you'll need more throttle to get going.

 

I guess that can be both good and bad. When you take your foot off the gas you will slow down much faster, right?

 

i use one act flywheel 8.9 lbs or something like that, i love it, gas mileage is fine, my d15b revs like a dream, depends on what you like.

yes, but its not so dramatic that it feels wrong

Ive had a lightened stock 12 lbs flywheel and a 6 lbs fidanza on my D16's and they feel great. Its nothing to worry about to where some "feels wrong". The only thing that felt wrong to me was that my SOHC actually revved fast! lol

But Yah daily driving isnt too bad, as long as youre good with your throttle modulation skills and foot control. On the 6 pounder I found it required more "blipping" of the throttle when I was getting out of a parking spot or starting off at a stop light. Rev matching when at higher rpm is also more precise.

Over all, its probably one of the first things I do to a swap. Its just that necessary for me now.

Yea I agree. I've got an ACT Prolite flyhweel, think its 8.4 or 8.8 lbs. Hands down the best mod I've done to my car so far. The acceleration increase is amazing. People like to say that you should go with a 12lb for street use and that any lighter than that is too light, I disagree, the lighter the better (within reason)
Theres no actual power increase per say, but there is a greater amount of power delivered to the wheels. Its power that you acutally feel as opposed to the gains "felt" by usual bolt-ons. Hope this helps

 

So, where is the best place online to find one of these? A place called gripforce (www.gripforce.com) quoted me $269 + shipping for the fidanza one with exedy clutch kit. Is that a good price?

 

With a clutch kit thats pretty good/average. I think at Clutchcityonline.com with any racing clutch kit you get a lightened flywheel in the package, i'm pretty sure. I got my flywheel on here for 80 bucks picked up with only 5k miles on it. Just keep an eye on the classifieds and local for sale threads if you dont wanna drop the money for a new one.

Once you have one in your car, you'll never what a car without one.

 

not to hi-jack your thread, but i was also wondering this..... however how would this 8.8lb flywheel interact in a turbocharged application? i've heard some stuff on here about the lightened flywheel making your car loose some "top end" and requiring more throttle to get going off the line. i have an act in my 95 integra and the rpms do go up pretty fast. but that car is N/a and i duno how it will work on a turbocharged car..

just want to find out some truth on this, enough of the he said she said.

 

me too, i was wondering about my h22 turbo and a lightened flywheel. pros and cons?
