Flywheel ?

[steveo_32]

I machined my flywheel, Got her down to 15.15 Has anyone done this before?
I see most flywheels are 12lb? just wondering if taking down the step and getting it balanced
won't kill me.  Kinda thought i would ask before putting it on!
Cheers!

You can get a stock T1 flywheel down to 9 pounds. just by taking the metal off the outside diameter, and under-cutting the gear. I think most shops trim to 12 pounds because that's the easiest to do. It takes a lot of extra time to cut off the metal under the gear.

Some important things to do, or not do: Do NOT cut metal off the back of the clutch surface. The flywheel will warp easily if you get it hot, or run a heavy duty pressure plate. If you under-cut the gear, watch out for the step in the front side of the flywheel. After you lighten your flywheel, it MUST be re-balanced, because you just cut all the balancing out of it. Get the clutch surface ground before you get it balanced.  

I drive a car with a very light flywheel, and have no problems. It just takes some practice, getting used to it.

I played around with flywheels on a GTI I had, thought lighter was better. Ended up taking like 6 lbs off it and lost a lot of bottom end torque, put a stock one back on. Do air cooled motors react the same as H20 when you lighten them that much? Mine is 12.5\" .... I mean lbs

my 356 S90 motor had a 7.5 lbs flywheel in it.

That thing took A LOT to get used to.  Tons of fun though!

Its just a 1641, But it built like a strong 1914 port and poslihed the heads and scat rockers, chrome moly push rods,nice oil pump good cam and new tin from Scat with a modified sump, I just thought with a set of Kadrons it would spruce it up a bit.
The Ghia could use a nice clean motor.
And the motor from the ghia Im gonna throw into the 59 type2
