I have my SPA fire suppression system 80% installed. I am currently planning on routing the line as shown:


Two nozzles for the driver and passenger lower leg area. One for the fuel rails, one for the starter dizzy area, and one for the turbo area.

My question is, do I have too many "T" fittings to assure equal suppressant distribution?

Another route I was thinking about was option 2:



Still the same number of "T" fitting, but allows more of a direct line of fluid flow into the engine compartment , but requires more bends and an extra fitting I don't have.

Or does it matter? Is the suppressant going to expand so quickly through the tubing that I don't have to worry about any one nozzle getting less then another?

 

It shouldn't matter. The amount of the nozzle and the total length of line will be the determining factor.

I would take the passenger side out.

 

Id have to agree with Andrie... Most applications I have seen have only two nozzles in the engine bay mounted in the upper front corners near the firewall shooting at 90 degree angles. This ensures overlapping coverage under the hood.
In your case I understand why you would put one near the turbo.
