Title: flywheels
Post by: aviation officer on July 28, 2011, 01:36:53 PM: Im going to replace the clutch on my 91 sidekick 8 valve. i was going to buy a 16 valve flywheel and get the 16 valve clutch. i wanted to know if the 16 valve flywheel will go on an 8 valve engine and if the flywheel will fit in the bell housing?

You get a bigger clutch with more holding power. Nothing wrong with that.

I guess that is where you are wrong.
The added friction area outweighs your ppsi of holding power theory.

If your theory was correct, then smaller brake pads would be better than larger ones.

the same principals work in Hydraulics too, a cylinder with twice the diameter
will exert 4 times as much force with the same pressure input, not twice as much
as most people would think

Post by: mrfuelish on August 01, 2011, 05:24:47 PM: I don't think the Hydraulics theory Is the same thing, I think compairing it to an elephants foot in mud verses a humans foot, the elephant would float on the mud but the human would hit the dirt at the bottom and have more solid ground to push off from. Lol.

Have you not been paying attention? :P
All 1.6 flywheels are the same...no matter if they came from an 8v, 16v, 2 door or 4 door.
All 1.6 8Vs had a 7.9" diameter clutch.
All 1.6 16Vs had an 8.5" diameter clutch.
So you can use either a 7.9" or an 8.5" diameter clutch on any 1.6 flywheel.
