Plumbing in extinguisher
Discussion
For the cabin most extinguishers would make sense pointing at your legs - mounting is typically just under the dashboard into the footwell.
In the engine bay it depends what you think is the most likely ignition source (presuming you have a single outlet of course), I'd probably go for the area around the fuel piping and inlet in case of a leak, as that should be the main source of combustibles.

One in the engine bay, pointing towards the most likely source of ignition, turbo, injectors, fuel rail etc.… take your pick. The other one, pointing at your knees/shins is a good compromise.
As a scrutineer, I could take the easy option and just say “read the blue book”. In reality, talk to someone who has had an under bonnet fire and see what they recommend. Being in a burning car certainly concentrates the mind… so I have been told…. I’ve been in the co-driver’s seat of an upside down rally car with a very strong smell of petrol…
The extinguisher system is not really there to put the fire OUT, the bottle is usually not big enough for starters - it’s to buy you time (5-7 seconds) to get out of the car.
As mentioned above, keep those cables free/lubricated, common fail in the bay for the first race or 2 of the season.

And please ,please ,please get into the routine of making the thing live when actually competing !
I lost count of the number of cars I attended in 36yrs of marshalling that still had the pins in the extinguisher systems .
Marshals usually check them while you're in the holding area, but yes I agree its easy to leave the pin in.I lost count of the number of cars I attended in 36yrs of marshalling that still had the pins in the extinguisher systems .
Scrutineers check for this too. At least a quarter of the field still have them in when held the assembly bay until told. Perhaps some of the more idiotic drivers may like to comment as to why they need telling 3 times about this in 10 minutes, like someone did on Sunday, or use the “best” response heard so far…
