Aluminum vs chromoly flywheel

[9240sx]

what is the better flywheel to use on a rwd sr20det.a aluminum type like the fidanza,or a chromoly steel type like the toda or jun.is the chromoly alot stonger.and is the aluminum alot lighter,stuff like that.thanks,brian

i Belive the weight savings are the same, but there are 2 very impertant differences. On the Aluminum flywheels, the friction surface can usually be replaced while the chromoly are usually one peice units. I also know that the Chromoly usually cost an 5hitload more than Aluminum. I have heard of high boost cars shattering aluminum ones, but that Is one thing that your average consumer would not car about.

In My honest opinion, I will always suggest the aluminum, but buy myself the item.Chromoly.

Chromoly is stronger, Ive heard of of aluminum warping and like he said, shattering..

Ive got a TODA chromoly and its awsome.

If your not looking for alot of power aluminum will be fine.

i've got jun ultralight chromoly. :thumbup

I know that doesnt answer your question but look at it this way, If companies like JUN & TODA use chromoly its probably for a reason.

The stock flywheel...that's where it's at :thumbup

If you want to lighten the drivetrain, I say carbon fiber driveshaft would be a better investment.

pff, for the cost of one custom CF driveshaft you can have an enjuku aluminum shaft and a light flywheel of your choice. While its probably overall the same weight loss, IMHO there are benifits. 90% of SR20 owners have no chance of breaking an ALDS, where as any sort of impact on the side/shaft of the CFDS could be disaster.

I still prefer CF if I'm going to do it. When will the driveshaft be impacted?

[Cyberkreig]

its not likely it will ever be impacted, BUT it could happen if you drive over something largely un even, a curb incident, road junk, or even from sliding sideways.

I dont aruge the benifits of CF over AL, simply that I, and I would guess most people, cant afford a $1200 DS. Not to mention if you have to buy it twice.

[cnichols]

Knock off about $400.

Chromoly is better!!!!

[cnichols]

You forgot the part where you explain why.

[Cyberkreig]

really? 800 isnt so bad. last i looked into one i remember the number 1200..

i'm not enough of a baller for either of those numbers tho =P

[cnichols]

Me neither...haha

Why do I need an explanation? Just say the word "Chromoly" Doesn't it just sound better?? " Hey everbody, I got a "Chromoly flywheel" Hehehe (Just being sarcastic :pface )
