Thomas Dolby Fan?
Tri-X has lots of "grain power" packed inside.
Processed in HC-110 can also make it quite punchy.
I looked in my Big Formulary and found a few things you might like...
Take Tri-X, expose it at EI3200 and process for 6 minutes at 21?C in Dektol.
Yes, you read right, Dektol, the paper developer. It will give you lots of grain by developing every bit of exposed silver in the emulsion.
Another one is Tri-X, exposed at either EI3200 or EI6400 (what a push
). Process in HC-110 diluted 1+12 for 10 to 12 minutes (depending on the EI) at 32?C...
You will get a negative with a very visible chemical fog that, when printed on Grade 5 paper will show a real grain storm!
The high chemical activity in those 2 processes will cause grain to become excessive. This is due to both the temperatures used and the high concentrations used. Both those tricks come from old time news photographers...
You can also use an overlay texture screen... but that's like cheating...
