proper placement of fire suppresion nozzles

(1/1)

up in smoke:
is there a standard location of the nozzles for the fire system, running none blown stack injection on alcohol, thanks mike

rooman:
The usual placement is forward of, or near the front of the motor and the same in the cockpit, relative to the driver. At one time some of the funny car teams were attaching a nozzle to a length of braided line and putting it inside the diaper as that was quite often the root of the fire source. On a blown car with 20lbs of agent I usually put one engine bay nozzle low (for an oil pan fire) and one at the base of the blower. With two cockpit nozzles I aim one at the driver's legs and the other at his torso.

Roo, on a dragster with 20#s, do you suggest two kits independant of each other, or one actuator dumping all 20#s ?

I'm plumbing mine this weekend.
