Unfortunately, I haven't been able to weigh it yet to see exactly how much I took off. I wanted to kill some weight, but still needed it to last for another year or so, threrefor I tried not to shave TOO much.

And BTW, for those that thought it couldn't be done, I did this on a brake lathe.

you can probably remove some more.........

have it weighed and balanced and it should be fine.........

 

see the low spot in the middle between center and outer edge, go that low from middle out to the starter teeth.

 

Holy hell! That means I can cut that ridge down by almost half of what it is!?! Kick ***! Thanks Mista Bone!

I imagine that you've done this plenty of times, so I'm curious how many miles you typically get out of one shaved this much?

 

I didn't do the work, a old fart at local crankshaft shop did it.

He used to race air cooled VW's.

You really wanna maintain consistant thickness across the flywheel, hence the stepping.

12.2 lbs, should last forever

i believe i read the rule of thumb is no more than 4 pounds off. is that right? two of my friends had their gsr flywheels shaved down to 14 pounds.

 

doesn't shaving a stock flywheel comprimise its strength? I've herard bad things about doing that... anyone else?

 

"I've heard"..........

 

chill buddy, I'm not flaming... Its an honest question, as I was thinking about doing it myself.

 

MistaBone was just making a point that you might hear a lot of ****, but that doesn't necessarily make it true.

You're taking metal away from where there used to be some. Therefor, it's not going to be as strong as it was before. It's also not going to be able to dissipate heat as well. However, my flywheel was warped to hell when I took it off, so that goes to show you that even @ the stock weight, you can **** it up. It's really all about not abusing it. Most of the people who talk about their bad experiences probably shaved too much, abused it to hell and back, or both, and still expected it to last forever.

I shaved and balanced my stock ITR flywheel 1.2 Kg ( 2.6 pounds )
It looks ok.

Well, I don't believe everything I hear: I was making a 100% valid point that I felt needed to be brought up. It is a fact that doing this to a stock flywheel WILL weaken it. Mista bone needs to chill and realize that ther are other valid views besides his own.

Did you balance your newly shaved flywheel? I've read many heated discussions on this topic, and decided against lightening a stock flywheel myself. Partly because I don't trust any of the machine shops enought in my area to modify a heavy disc that flys at 8100rpms near where my friends will sit. The story about a guy on this board who walks with a limp because of a stock lightened flywheel really topped it off for myself. I'm not necessarily saying it shouldn't be done: I'm just saying that it has negative effects as well.

Man, All he said was "I heard".....anyway, I heard (hehehe) the same sought of stuff as this and my car is RHD so I sit in line with the flywheel so I aint doing anything to the standard flywheel. I'll pay the extra but that;s just me....

 

how is this.......

"I heard the search button works"

 

whats your problem? I'm not some newbie who doesn't know what they're talking about.

I learned about these discussions via the search button on this board, as well as other boards more than a year before this post. Its always good to get diffferent perspecitves on a debatable topic without a single, solid, one right answer.

Did you not notice that I posted a link to a previous discussion on the topic in my last post? Pay attention.

who are you, and where do you get in coming in to this topic and making an uneducated comment? Funny how your post history shows almost all of your posts have been in OT forums on honda-TECH.com.

Why do you feel the need to come in and turn a perfecty good discussion into a waste of bandwidth? I'm here to talk about cars, not listen to BS from people who don't know what they're talking about.

I've build, all by myself, a civic that ran a 13.003 @ 109.95mph at 6000feet elevation. I'm about to complete my turbo h22 civic hatch, all built by myself.

I spend my time learning from the wisdom and experience of others who know more than me, and actually going out and building cars instead of drawing little animated .gifs to make fun of people I know nothing about.

 

hey servion, just let these ppl lightened their flywheels. these people are about being cheap and not safe. some also like to argue because they got nothing better to do. piece

 

Yet you came in and attempted to flame a trusted memeber of the board who time and time again has provided valid infomation and you....well your as stated above a ******* newbie who should calm the **** down.

Even with a stupid little link of a damn gif you flip out. Get the **** out of my forum.

 

woah back up pal, and look at the entire thread. I did not start the flame... I asked an honest technical question, and was returned with a smartass comment... one I decided not to back down from. I did not say that mista bone is not a trusted member. I would not doubt that he is a very knowledgable honda tuner/tech/whatever. I was simply saying that he handed me a smartass comment to a valid question. No-one is always right (including myself)... and this topic is one that has no solid right answer. There are both pros and cons about ligthening a stock flywheel. It is a FACT that there are cons to lightening a stock flywheel. I was simply making another technical comment to start a technical debate... not a flame war.

If you're going to post again in this thread, I suggest you make yourself useful and post a real response to the topic at hand (to remind you: lightening stock flywheels, in case you forgot), instead of attacking someone you don't know simply because they have a lower post count than yourself.

BTW, Looks to me like you are a 'normal user'.... I don't see 'moderator' beside your name. This is a technical forum, not for a flame war which YOU started by straying from the topic in a TECHNICAL forum. It's not 'your' forum... stop wasting bandwidth if you're not going to say something useful.

 

whats with the newbie ****? your time on the internet indicates your skill level with cars? lame..make up a another deragatory label..lol

 

I think in all situations everyone over reacted.

He stated "I've heard" and in the link you provided (Which has been read by the creater of the thread already) the first 4 people that said anything about reliability stated "I've heard".

Mista has done this. That is why he answered I've heard. And he recommends a specific weight. While some have stated, "I've heard". Mista can say, "I've Done" and stating that he has "heard" that the fly wheel can come apart simply means that his have not.

And seriously, who gives a **** about post counts. And yes, even though it says "normal user", ask anyone who posts in the Tech forum, when I can help I do, I don't see you answering other peoples questions....you just come up with more questions.....give an fricken answer you leaching ***.

The first link I posted was merely to show that I have performed a search on this topic. This is not the only board that has valuable information on a topic such as this.

As a matter of fact, just yesterday I answered someone else's question... you should look a little harder:
https://honda-tech.com/zerothread?id=258398

I answer questions to topics that I think I can offer some insight to where it hasn't been done in the thread already. I don't answer hundreds of questions, usually because someone else beats me to it or I don't feel that I can offer up enough info. that hasn't been offered already. That, and I am not surfing honda-tech with all my free hours in the day.

Like I said, I'm not saying mista bone doesn't know what he's talking about. I was merely pointing out that not all the effects of lightening a flywheel are positive.

I certainly don't care about post counts... you're the one that went out of your way and came into a thread (in which you have offered no insight into) to call me a 'newbie'.

The point here is that we've got a good place to share technical information, and we don't need to ruin it with stupid egocentric comments such as the ones shown in this thread.

 

Servion, the comments have been directed at your demeanor, NOT necessarily your automotive skills. No one knows how much experience you have, and frankly, no one cares when you act the way you have, in this thread. Take a few deep breaths, relax & realize that no harm was meant by the original comments. Anything that you were fed after your second reply, you deserved, and as much as I hate to say it, you should take like a man.

And some people like to post a few meaningless sentences, which contribute nothing to the topic at hand, in a technical thread. They proceed to pass judgement on those of us participating in the duscussion, assuming that we are cheap and not concerned with safety, because we are looking to extract more power out of our motors, working with what we currently have. They make this assumption based solely on the few short paragraphs contained in said discussion. Had Servion not overreacted, and just taken a point, there would not be an "argument" for you to comment on. Hell, there STILL isn't anybody arguing. It's just Servion becoming more & more irate and everyone telling him to chill.

And dude, if you hold down what we call the...

"Shift Button",

Then press a letter, you'll get what we call a...

"Capital Letter"

You'll want to perform this function to get a...

"Capital Letter"

With the first letter in each sentence that you...

"piece"

Together. This is good to do when you want to NOT look like a moron.

 

Look at the 9 o clock to 11 o clock position in the pic I posted. Those extra holes are there due to balancing.

Stock flywheel can handle in EXCESS of 450 hp. The way mine was lighten, no area is thinner than the thinnest section, hence the stepping. Most cut factory wheels are straight cut on a brake lathe, might be too weak towards the center. ACT used to do this, but there was questions about their balancing, they soon dropped them. Figure it will cost $150-175 to PROPERLY lighten a factory flywheel and balance it. Mine was balanced to 20% over expected rpms, or 9000 rpm.

I would NOT do this again, but just buy a 10 lb flywheel for $250.

BTW a NA D15 with LOSE performance with a LW flywheel and using slicks. You NEED the stored energy to get the car moving.

BTW, I never said newbie, but have posted the same info above countless times. In fact MOST of my post count comes from REPEATING same info over and over.
