Topic: Scattershields?

[2nstoys]

So there is a rumor going around our clubs that there will be a USLMRA rule on mandatory scattershield needed on all ungoverned engines that turn over 4000 rpms for next year. Has anyone else heard this? I did not see this in the new 2010 rules. Just trying to get a head start on if I need to build or buy one. Thanks, Glenn

It is just in the discussion stage, no more than that for 2011, along with mandatory billet aluminum in the Prepared and F/X. It is still just highly recommended now.

If they are talking about the same scatter-shield they've been using, those shields are not effective and cannot be relied on to protect anyone. The shield needs to be redesigned to encapsulate the flywheel in 1/4" steel like the shields used in drag race-cars, unfortunately that would require engineering and testing which would be unneeded if billet flywheels are made mandatory.

in my opinion, billet wheels should be mandatory in any un-governed class....if ARC sells enough of them i could see the price dropping a bit on them.....if not, they still a good bang for the buck...just my opinion tho!

but i know alot of people who cant afford a billet flywheel and that rule would shut them down

[George Herrin]

I can see using the stock wheel in a STOCK class even ungoverned. I have yet in 12 years seen one explode under those conditions, Its when you add a cam and start turning them upwards of 6000 or more and they lighten them that it happens. BUT if used in a stock class even ungoverned, rules have to be enforced. Even to the point if your caught doing something which would jeapordize safety atuomatic ban.

I think modified stock flywheels should be baned! if its not a safety rated BILLET or stock it should not be alowed on ANYTHING!

the local 3 clubs i race with....modified stock wheels are banned! believe that is becoming the norm......but it's kinda hard to enforce without removing flywheel, but tech guys are trying.....so that helps!

i agree 100%

Is there any video of a flywheel shattering. I just can't imagine it. Is it a common thing.

i honestly hope nobody has a video of it happening......if you do some searching on here, there are pictures of the results....not good!just a couple months ago, there was a post about a guy getting hurt pretty bad on here....broke his leg i believe...

[2nstoys]

That guy was racing at a track near me. That's why we have banned any mods to the stock flywheel.

[RICHARD_NOLIMIT]

So a stock flywheel won't shatter as long as it's not moded right? And another ?, What is there to mod on a flywheel.

[birdman_express]

We are not going to let anyone teach anyone how to modify a stock flywheel.
A stock flywheel is just that, and meant to stay unmodified, and thusly
remain stock.

Removing the magnet from the inside of the flywheel for the stator is considered modifying a flywheel as well.
