Need some help making sense of stuff... need someone with a CAMS manual!



Basically want to know what size(s) extinguisher you need.



Whats it mean by scatter sheild?

Cheers for any help!

I don't have a current CAMS manual but the extingusher used to be a 1kg as a minimum.
A scatter shield is a steel plate on the outside of the clutch housing to protect the driver from an exploding flywheel/clutch.

Go to a race meeting, you will find heaps of CAMS manuals choking the wheels of cars so they don't roll away. If your only doing as suspersprint you should'nt need a scatter sheild, by the way a scatter sheild is a aluminium plate that goes around the flywheel housing, so in the case it exlodes, the fragments don't go through the firewall & cutting off your jatz crackers.

Hay, it's not about the car, it's not about the venue, it's about the people that come here. Peter Dwyer, Mayor of Hay NSW.

minimum 900g, and it's gotta have a metal strap and retaining clip so that when the car is on fire the plastic strap doesn't melt closed, cos as the car is burning while the extinguisher is within reach, but surrounded by flames, you'll be trying to grab it instead of running as fast as you can...

CAMS manual Schedule H (3 SpeedEvents, Races and Drifting) states:
ii - It must be of at least 900g capacity
iii - It must be restrained under an acceleration of 25G
iv - it must be capable of removal by the driver without the aid of tools.
In REALITY the scrutineers will insist that - It must be a 1KG capacity and lass than 5 years old (going by the date stamped into the base of the cylinder). It must have a metal restraining bracket - not plastic, and the driver must be able to reach it whilst seated in the driver's seat.

Scatter shield - generally not required on road reg cars or for sprints, hillclimbs etc.
Requirement is 6mm steel or A5083H321 alloy plate around the flywheel casing extending 140 degrees above the horizontal.
The one on mine (pictured) goes all the way down the back of the motor and across the top. It's held in place by the 2 clutch slave cylinder bolts.

I will be doing khanacross (basically autocross but you start and stop in a garage, makes it a non-speed event over the speed event if it was an autocross).

It's not a Mini, will be an AE82 Corolla. I just have to bite the bullet and buy one!

I would think a scatter shield would be a bit extreme for what i'd be doing?? I better contact the organisers...

From the 2000 CAMS manual (the last one I bought)



So the rules are clear, you don't need one.
(unless they have updated the rules since 2000)

Regardless of whether you need it or not , might pay to get a bit of plate the required thickness and put around the clutch housing . Not sure what the corrola's like but I've seen what was left after a mini clutch exploded and there were some reasonable sized bits made it into the cabin at great speed , Bit of alloy plate won't weigh much or cost a lot (find an aluminium fabrication place and ask if you can scrounge through their scraps , or a metal recycler) but might slow the bits down enough to stop them doing major damage , don't know if it'll stop everything but if it reduces the risk which is a fairly low chance anyway , it's got to be good .

By the way , on the subject of fire extinguishers , has anybody here plummed one into a car before so the bottle is in the cabin but there's piping on the nozzle that directs the powder to flood the engine bay (aimed at carb/master cylinders and any other potential problem) as well as a handheld one to use seperately ? Been thinking of doing it in the Fang as it's not the quickest car to get out of and you're sitting on the fuel tank , anything to slow a fire down if not extinguish it completely might be a good thing ....
