Autocross rules

Hello All,

Question: why doesn't the SCCA allow flex fans in autocross?

Re: Autocross rules

I'm surprised they don't have a separate class for flex fans. They seem to have a class for every other variation.

Re: Autocross rules

Because unlike a clutch fan, at high speeds it keeps on going, faster and faster. Whereas the clutch fan will stop/spin freely at higher speeds.

Ever try spinning a CD too fast in an optical drive? Sort of the same thing. They are known to just fly off, rip through hoods and mangle many other things.

Why there isn't a separate division for them, because they're dangerous in racing...period. So I've read. Adios.

Yeah, someday that is the plan. For now though I've invested in a clutch fan set-up due to the cost.

When I can upgrade my electronics I'll go with electric fans, it's not in the cards at the moment though.

Ha, back in the early days of CD burning I made a disc without finalizing it then put it in a friend's boombox. When it started spinning too fast we popped the top and it flew out like a helicopter.
