For that past hour I have been having a debate about which one would benifet me better. I said chomoly would b/c it is stronger and better heat resistant. He then said that the aluminim flywheel is stronger and better heat resistant. I want your guys's opinion. Which one do you think is stronger and more compatible with heat?

 

my vote goes to the ACT flywheels... i own a 8lbs ACT myself... Chromoly

 

Both are good.

There are some horror stories about aluminum flywheels coming apart into a million pieces and flying into the cabin. Very infrequent indeed.

What it comes down to in my book, is how you go about servicing them. Aluminum is not suitable as a friction surface, so most aluminum flywheels have a replaceable friction surface which is what the clutch disk gets pushed on to. When you replace the clutch, you replace the friction surface. Chromoly flywheels are just like any other steel flywheel, when you replace the clutch you have it resurfaced.

Some people like it one way, some people like it the other. Neither one really seems to be an "advantage" to me though.

 

Sorry but that is chromoly that comes apart. My vote is for the aluminum 7.4lb fidanza flywheel, the aluminum will not break apart and therefor will not KILL you!

Chromoly < aluminum

Okay well then that makes it both that are rumored to come apart. Because there are plenty of places where people have claimed that aluminum will come apart and now you're saying that chromoly is going to.

Personally all of the people's cars that I've seen with either type of lightened flywheel, they've never had it disintegrate. So all the rumors about that sort of thing are grossly overexaggerated to me.

ive never herd of the chromoly fw's breaking apart, only the aluminum. either way its really rare anyway. im goin with a fidanza.

 

didnt Lisa Kubo blow up a Jun flywheel like 3 yrs ago?? the said the only thing that was salvaged was the manifolds and the valve cover

 

hahaha...Thats amazing. It must have been pretty violent.

 

i dont know i think that even though it is a little heavier i would probably trust the chromoly one. aluminum doesnt dissapate heat that well and arent that great under high heat applications. chromoly is super hard, super strong, and doesnt weigh that much more. whats the difference 7lbs to 9lbs. 2 pounds and peice of mind are worth it to me.

 

chrome moly is brittle and shatters , thats why Nascar uses Mild steele for their Chassis.......

 

Aluminum does not shatter, it warps. Chromoly shatters...it's far more brittle than alum. I'd trust either from a good manufacturer, but forced to choose I say aluminum.

 

from all i have read the only dif is alum is better at low end it allows easier movement, but once spinning and it has the inertia chromoly (aka the heavy flywheel) starts spinnning and your better off and who cares which shatters we're driving imports with a passenger side tranny(jk)

 

Doesn't matter. Get the lightest and cheapest. My vote goes to Fidanza. $300 and 7.5lbs.

 

I agree.

 

and in the end, thats all that matters

got my ClutchMasters 7.5lb flywheel for $299 (thx chad)

and i COULDNT be happier

i actually left the stock one in there didn't have the moola at the time just finished my turbo and clutch went shortly after so i had no cash had to borrow money for the clutch i have had no probs with it

 

The best thing you could do if you're concerned about the strength of your flywheel is to get your stock one machined. You can get it lightened very easily by an experienced machinist. You can easily get the stock one center weighted and cut down from 18 pounds to 10-12 pounds and it will be a lot stronger than an aluminum or chromoly flywheel.

 

I have a quick question about the flywheel subject, on a 220hp max turbo setup would it be better to go with a 8.8lb (too light?) or be better to go with a 10.8lb, or maybe just a stock?

 

Well On the K series R motors honda is using Chromoly so i guess honda knows best

 

If Honda had done everything the way I would've wanted it I wouldn't be modding my car now. You'll find a great many people swapping out their flys for lighter chromoly and aluminum on ITRs. Myself, I got a great deal on a Fidanza alum($290) flywheel and jumped on it.

 

I'd go with the lighter option.
