Onboard fire systems, Any recommendations? Options

[ThePaintedMan]

Hello Paddock readers,
I'm getting ready to order a fire system for our car and I thought this might be a good time to see if there are any opinions on which system to go with. I think that I've decided to go with the newer AFFF style system and the only real stipulation is that it be 2.25 liters in capacity or above.

FourBlades has an OMP system for his IMSA car. I think it's this one :

There is also this style, recommended by Chumpcar:

And finally, the SPA 4 liter system which also seems to be a bit cheaper than the others:

Any major difference between these? Is the mechanical actuator or the electrical solenoid more preferred?

I'm still using Halon
but some of the newer systems are fine

note that halotron is only 50% as effective as halon, so buy 2x the size if you go halotron

once you've seen a fire... you will believe that you can't go to big. I'd buy the largest volume you can afford
you still have to practice exits and prepair as to how you would use it. you have very little time and extinguishers run out VERY fast in the case of an actual fire

most of the fires I've seen the onboard supresses the flames for only a few seconds and then the fire comes back if its source of ignition is still there (leaking gas, oil)

I feel like there is only a small chance (like 20%) the onboard will save the car unless you are near a corner station
