The reason that the 904 billet drums aren't plentiful like the 727's is because the factory steel 904 drums aren't a problem. The diamater is so small, they don't have the mass/rotational inertia to pull themselves apart.

I continually ask, and I have NEVER seen or even heard of a 904 drum coming apart. They are just too small to do so...



I agree and it's typical how NHRA lumps everything together making it harder for the racers. 904's don't blow up and yet we still have to have shields/blankets. Probably because the tech guys can't tell the difference between a 904 and a 727.

I have broke a couple 904's but never blew one up and I have never heard of it either.

Has anyone ever heard of a 904 blowing up?? Anybody??
