I have one on my 7A-FE. At first I liked it, but now I am frustrated with it.
I need to keep the RPMs a bit higher in order to move off from a stop, without stalling, and it sounds like I am just learning to drive a stick. It is worse on a hill, and I think my clutch is suffreing for it.

If I ever need to pull the clutch, I will be re-installing the original flywheel.

I don't recommend it if you are not racing.

Anyone interested.....I have a brand new 4A-GE lightweight wheel flywheel for sale, still in the box, never installed.

there you go, dunno how good alluminium is withstanding that much heat and or stress.
Another way to get it lighter is to send the standard one for balancing and machining.

I've always heard scare stories of aluminum flywheels so I'm always scared of a high RPM flywheel explosion. Especially with this car where the flywheel is directly inline with the driver.

Both the aluminum flywheels I have, have a steel mating surface for the disk.

now it's just internet myth that the aluminum flywheels break apart..... I'm sure it happens in all out drag cars but they're typically producing 1,000hp..... and at that amount of power anything can break.

I forsee other problems with aluminum flywheels that I have expressed concerns about in the past.... which has to do with steel mating surfaces, bolts, and steel starter ring gears.... their expansion rates vs. aluminum expansion rates.....

Heh, well it was before the internet took off that I heard the stories, but anyhow, yea, they were still stories. Nonetheless, they don't sell scattershields for looks. And you're right, the blame isn't solely on the flywheel material being aluminum. I guess I'm just that conservative to feel that way.
