Just got my order in for a Safecraft fire system (www.safecraft.com), and asking some questions of the folks at Safecraft got some interesting information on the Halon 1211, 1301 and the newer FE36 agents. I have an older 10lb system with 1211 which as I recall he said was the better agent at the time for a few reasons that sounded good but not at all environmentally friendly, and most all of it is recycled from old computer room halon system.
In talking with them about placement in the GT40 my concern was heat if placed in the under front hood area. He quickly chimed in that 1211 and FE36 were the best for that as the boiling point was 200F and that the 1301 was only 140F. So if in a HOT area, skip 1301. I'm assuming that is under pressure as delivered.
As for agents performance the best was 1211 for a given volume, both the other agents need 10-20% more agent for the same supression (he said roughly). 1211 was more expensive then 1301, didn't check on FE36. One note is that for sanctioned events the sanctioning bodies are looking towards FE36 as environmentally friendly while still doing a good job.
I ended up with a 10lb RS manual pull with 1211 Halon, 3 nozzle system
