Summit says that the Super Powershot Nitrous solenoids are good for up to 175 HP, and the fuel solenoids are good to 200 HP I think.

I'm running them on my car with a 100 shot and they are fine.

 

Im not sure about the NOS solenoids.I know that my personal opinion is that the quality is very poor on them.Thats why they run them in a series.

As for the NX shark nozzle.It will flow 250HP.THe -3 line going to the nozzle maxes out at 200.If you want to spray 250 all you have to do is upgrade the hose from the solenoid to the nozzle to a sho hose.

If you can find someone to buy those solenoids while there still working I would sell them and then upgrade to the NX Iceman solenoids.

The only time I've seen NOS brand solenoids run in series is for the dry kits. The first solenoid opens with a tee between the two that goes to a regulator to bleed some of the nitrous pressure off to the fuel pressure regulator to bump fuel pressure while spraying. The 2nd solenoid is an added safety measure to protect just in cast of a solenoid that sticks open.

All of the NX kits that I've see are wet kits if I remember so they don't need to worry with bumping the fuel pressure.

 

Dave,

How much for the iceman solenoids?

 

The nitrous solenoid is about 118.00 and the fuel solenoid is 91.00.

Will those solenoids mount on the same brackets that the NOS solenoids use?
