Aluminum Flywheel?

[mrfreyguy]

I was wondering if a stock aluminum flywheel from a Briggs would hold up at higher rpms? I saw one go on eBay for $10 shipped.

Racers will tell you that they are dangerous above 3600 RPM, and that they kill (and have killed). People here will tell you there is nothing wrong, and that people who talk about exploding flywheels are blowing hot air. Personally, I wouldn't touch it with a 10 foot pole, if simply for the fact that you're dealing with a used flywheel, that you've never seen or ran it, and you don't know how old it is or how people have treated it before you.

Really, its not a thing to skimp out on. I've never seen one blow up, I turned a cast Iron one to 5600 without a problem. But I got a racing aluminum now. I mean, I'd rather be poor than injured or dead. It comes down to like he said, who you choose to believe.

I hear what your saying. Is billet the way to go? On agk's websit they have a aluminum flywheel and a billet flywheel at the same price.

Billet is the only way to go above 3600 RPM, especially on a clone motor.

Im not sure of the difference really. I have an aluminum one, with the fins cut. and I turn it 8500 plus. Im positive billet is better, I just dont know why... lol

Over 6k and climbing on stock aluminum flywheels.
Make sure flywheel nut is torqued to factory spec.

I'll just go the billet way. I'd rather pay $100 to live 70 more years.

A stock B&S engine cannot spin fast enough to destroy it's own flywheel. Just doesn't happen..EVER!
Rod will go (if at all) long before flywheel, assuming there is no load. Internals are far weaker than flywheel.
You (and others) are just making the scare mongers richer.
Give me the $100 and I'll guarantee engine will operate (sight unseen) for something close to forever.
Nowhere (past or present) is it documented that a stock configured Briggs blows flywheels for any reason. If they did, the lawsuits would abound.

that makes sense.
