FLYWHEELS DISCUSSION.....one piece vs multiple parts

[noridetoolow]

I keep hearing comments about multiple piece flywheels coming apart. I am sure these are valid points but I cant see a manufacturer ( especially a reputable one ) putting out a product prone to failure. Yes, anything can and will break...but is it .02% of a specific products that fails ( which might be acceptable to a company ) or is it 30% of the products that fail? Most reputable companies would not even get close to..... I would imagine even a 10% failure rate of any of their products...they would be put out of business by word of mouth. I guess maybe I look at it this way...I personally see for example Fidanza as a reputable company ( I have heard good things about their products and see them at events )...so lets put this in easier terms....if I was to buy a 3 piece flywheel from Yugo ( anyone remember them??, alright...how about KIA? LOL )...I would not feel NEAR as comfortable with that as I would a 3 piece flywheel sold by Honda or Toyota. I would expect a better more reliable product from the latter. Am I making sense?

Another thing that needs to be considered is how hard we plan on driving our cars.....my DA is a daily driver...I want something moderately quick and fun to drive but I don't plan on taking it to the track and I do NOT street race. Yes, I will get one it here and there, its fun to drive....but in general... I am not going to be very hard on the car. For my application, I should be able to run a 3 piece flywheel made by a reputable manufacturer in my car without any issues. Considering that the 7.5 pound flywheel is designed for track use anyway...I should be able to drive the car how ever I want and not worry about it...to an extent that is...there is a point where abuse is abuse.

Anyway.....thoughts...comments......

exedy makes a 1 piece chromoly flywheel. It is a lot stronger than aluminum and only weighs a little more, which is actually good since most lightweight aluminum flywheels are actually too light.

it all depends on your application

road racing guys prefer lighter flywheels so they can take advantage of the slightly quicker rev. Considering their cars are constantly moving around the track, the engine needs less momentum to produce power.

Drag racing on the other hand, a slightly heavier flywheel is in order, considering their type of racing is performed from a dead stop rather than "who comes out of the corner faster."

he said he does not road race, so I suggested the slightly heavier chromoly steel Exedy flywheel.

I agree with you that 1 piece chromoly flywheel is much stronger. Usually aluminum ones are about 1 or 2lbs lighter at most, and nothing wrong with that.

I already bought what I have, done deal. I started this more for comments and to get others ideas and thoughts..out of curisousity more than anything else. Its just that so many complain about flywheels that are not 1 piece that I wanted to hear others comments on this subject.

If I could find the pics of my old Clutchmasters flywheel with ring that was separated, I will post them up. I personally don't like 3 pieces design.

My flywheel bolts failed a few months ago.

ACT street light flywheel. ACT is a very good company.

nothing wrong with having a light flywheel. the myths must stop. there are multiple articles on team-integra.net and dyno charts proving you dont lose hp from a lighter flywheel. it only helps. im sure like anything, there is a point of no return, but there is no problem running a 8lb flywheel in a drag car.
