Morning - just two quick questions on a twin plate system

I have two compucar 100 hp fixed plates atop my tunnel rammed 383
(Took years to find a match for the first one I bought )

My questions for those running two plates:

First - How many solenoids are you running ? Two fuel and two nitrous ? One of each per plate ?
Or have you plumbed one fuel and one solenoid to power both plates ?

Second - since I have two fixed 100hp plates - I'm going to assume I am not adding 200 hp to the engine. Maybe I am wrong.

I'm aware these fixed plates aren't the greatest and I could get a lot more out of an adjustable set. I plan to upgrade with the next engine
