Does anyone make a light weight flywheel for a 1st gen 1.9?
You were right the first time. It'll take less hp to turn the flywheel, which will allow it to rev faster, but you will not get any sort of "power gain." The engine will not produce more hp because the flywheel is lighter.fixitmattman said:Not true tito,
The lighter the mass of the flywheel, the lower the mass moment of inertia and the less horsepower it takes to turn it. Essentially the car will rev faster and get a small power gain. Of course the more material you remove from your flywheel, the less smooth the engine will run to an extent. This is one of the two main ideas behind the underdrive pulley as well since they're about 3lbs lighter than the stock pulley.
I can see where your coming from on this James, and esentially you are right in a respect. The engine will not produce any more power than it already does. What you are doing is freeing up power lost due to having to accelerate a larger mass. Everything that moves takes energy to get it moving. If my flywheel is lighter and takes 2 less hp to accelerate and get moving than stock, that is two more horsepower available to me for output.James92Scort said:you will not get any sort of "power gain."

No. You're not getting what I'm saying I guess...you will NOT make more power by lightening something up. If you make 88 flywheel horsepower and you lighten up your flywheel and make 90 hp, you were already making 90-92 hp.fixitmattman said:So essentially, if I had 88hp with a parasitic power loss like a heavy flywheel, and free up 2hp from lightening it, my output is now 90hp.
Forgot to add that :wink:

He will be making a few more horsepower, but he'll obviously never be able to tell the difference...
Lightening the rotating mass does increase HP, but 5-10 lbs. isn't going to make too much of a difference.
That's not too bad, I found one for my Si for 275 or so...for a 7.5 lb flywheel which will be shipped for under 300, that isn't bad...but 450 for a flywheel? must be rare or inlimited quantities.kikoy said:you guys ever heard of "FIDANZA"?...they make aftermaket fly wheels for almost any application... ...i tried asking them for my 2nd gen scort(1.9) and they quoted my me for 450 bucks...but its worth it cause you can replace the surface where the ckutch meets the flywheel....anyway here is the link http://www.aluminumflywheels.com/welcome.html
