aluminum driveshaft and flywheel

[EMW150]

I know you didn't...but your example about inertia was on a track car and then a street/strip car. What about daily drivers...those in traffic all day long, etc.

Like I said previously, I wouldn't put an aluminum flywheel in a stock 5.0 with stock gears. On a torquey street car with a decent gear, you will have no driveablility problems.

No one has ever say you will see a "big difference"...but we are just posting some cons of it (pro being a bit quicker acceleration due to a couple factors). You noticed a difference either way...whether it bothered you or not. What is wrong with some posting some of the differences they might experience?

None. What's wrong with me posting the Pros of it?

Sure you can replace the inserts...but guess what is adds up. A resurfacing cost $25 bucks at my local machine shop. In my opinion on the steel inserts...it is like buying a nitrous kit...you still have to buy the nitrous...over and over and over...it may be a fraction of the cost...but you will see what adds up.

You could say that about any part on your car then. All parts wear out eventually regardless. The steel inserts do not wear any faster than the surface on a steel flywheel. You act like you have to replace them every race. My last one lasted 3 years of street driving and probably 100 passes (all powershifted) at the track with a Spec III clutch. That's pretty impressive. Personally, I'd rather replace my steel insert than have a $25.00 resurface on the local brake rotor lathe.

EMW, what are you spinning that motor to to make that kind of power?

Thanks,

I shift @ 7,600. It peaks around 7,200.

Your still going to notice a difference...though it may not be as pronounced. That is the whole reason I posted this so they know.

There is nothing wrong with posting "pros" of a mod but let the potential knower know the "cons" of it so they know what they are getting their self into, that isn't to hard to do is? "Sure nitrous gives you more power...go buy it and your all set!" - Something like that is misleading...you need to make sure he has access to a tuner and all the supporting fuel components. (Cons on the wallet and ease). Pros/cons and needs need to be expressed when suggesting a modification...

Most people go a long time with their stock flywheels before replacing the clutch in them (some 130k miles)...so your little inserts will last that long?

Resurfacing is resurfacing no matter how bad you make it seem (brake rotor comment)...they use the tool that gets the job done. It doesn't matter what they use it on...does it?

That comment is almost funny. Are these 130k mile cars putting 433 to the wheels and launching on slicks regularly at the track? How long do you thing a stock cast flywheel would last in car that saw some serious abuse? And yes a quality aluminum flywheel with steel insert would easily last that long under those conditions.

That's where you're wrong. Just FYI I copied and pasted this from Ram's website.


"Do I have to resurface my flywheel before installing a new clutch?

* YES!* In order for the new clutch disc to properly seat to the flywheel, it should be resurfaced using a flywheel grinding machine.* Do not lathe turn flywheels!* This can cause a taper in the face that will not allow the disc to seat properly.* FAILURE TO SURFACE THE FLYWHEEL CAN NOT ONLY CAUSE PREMATURE FAILURE, IT WILL VOID ANY WARRANTY.

* What is blanchard grinding?

* Blanchard grinding is simply resurfacing the flywheel with a stone cutter that spins opposite the flywheel and leaves a ‘cross hatch’ type pattern on the surface."

Not likely...but is your car a daily driver? That is what I thought

You missed the point I was trying to make. You were making it seem "cheap and wrong" to resurface the stock flywheel by using a "brake rotor machine"...

I was simply dismaying that...

Mine isn't a daily driver, but I wouldn't be afraid of putting an aluminum flywheel in a daily driver. I'd put it up against any cast flywheel for longevity.

To me it is a cheap way of doing it. If it was a beater car that I didn't care about, I wouldn't think twice about using a brake-lathe'd flywheel.

It is easier to say that when it isn't your daily driver, isn't it?

I wasn't talking about longevity of a flywheel in that post. I was talking about the "abuse" of 430rwhp on slicks...

My point exactly..."beater car"...
