Aluminum Flywheel
Does anyone have experience with this modification? Good, bad, worth it?
Thank You.

Re: Aluminum Flywheel
Many have had good experiences with the lightened stockers from Millers Mule.

Re: Aluminum Flywheel
How does the car feel with the lightened flywheel?
I'm doing the clutch now and the machine shop is willing to help me shed some weight if I want.

Re: Aluminum Flywheel
Would an Aluminum one be the better one? How much would the best on be? Also, can someone explain what cdn stands for and what the equivalent would be US?

Re: Aluminum Flywheel
The clutch will feel the same. Less rotating mass to bring up to speed, so acceration is increased, however your revs may also drop quickly between gear shifts. Check out Jason Millers website at Miller's Mule. Search around the site and you will find three cad drawings for lightening the flywheel that you can give to your machine shop. The cost will vary with the amount of material to be taken off and the shop's rate. GC recommends doweling the flywheel to the crankshaft with two 10mm dowels, to reduce the stress put on the bolts when the flywheel is lightened. I think the holes are already in the crank you just need to drill them through the flywheel.
Re: Aluminum Flywheel
Matt, regarding the dowelling holes, are they the two 10 mm holes in the last technical drawing on Jason Miller's site?

Re: Aluminum Flywheel
cdn= canadian dollar. at the moment around $1.20 cdn is $1.00 usd. so 50 bucks canadian is about 40 bucks US.(I think)azygoustoyou wrote:Would an Aluminum one be the better one? How much would the best on be? Also, can someone explain what cdn stands for and what the equivalent would be US?

Re: Aluminum Flywheel
The car will seem to accelerate more quickly and be more rev happy. The downside is while cruising, you got to keep your foot in the gas to maintain a constant speed.mosu wrote:How does the car feel with the lightened flywheel?

Re: Aluminum Flywheel
I have to do that anyways, so no downsides that I can see with some weight savings on the flywheel
Thanks for the clarification!

Re: Aluminum Flywheel
What seems to be the best answer to the question regarding a lightened flywheel vs. an aluminum one? I seem to recall the difference in weight (using M. Mule's website) to be quite substantial between the two. I'm pretty versed on the positives of lightening the flywheel, but is going to an all aluminum just too aggresive an approach?
Who can finally put an answer to the question??? Inquiring minds want to know!
Thank you all

Re: Aluminum Flywheel
Henry,
I will try to add my two cents to this. first of all what are you tring to achieve? Faster acceleration or "Safer" higher engine RPM? As for the first item either solution will work lighten stock or aluminum, but if you want to spin your twin cam past 7500 aluminum or even light weigh steel is the way to go.

Re: Aluminum Flywheel
So if a fella wants race, go aluminum, every pound counts, like everyone said. your car will rev quicker because it don't have to spin that big ass weight hanging on the tail end. If you go aluminum back there, you might as well go aluminum on the front crank pulley. Why do one without the other. you would'nt run two aluminum rims in front to save weight while installing two steel rims in back to gain traction. Although it sounds like a good idea now that i said it. So when you go aluminum flywheel you also should be looking at a light weight clutch, why would you hang a heavy clutch on a lightweight flywheel you need a clutch that weighs only 5 lbs from this site here. http://www.hrpworld.com/index.cfm?tpc=T ... on=product So its like where do you stop? One part aint that great without the other part, for the most part anyway. besides the aluminum flywheel is $500 and the clutch is $800 and the front pulleys will be $400ish and so on and so on. Oh ya, don't forget the lightweight starter, thats worth like 20 lbs. So in a nut shell stick with having the factory flywheel shaved down.
Re: Aluminum Flywheel

Normally you stop when the money runs out
the stock starter weighs 16lbs, the lightweight unit weighs 8lbs
