Thread: NOS Nitrous plate differences

    Default NOS Nitrous plate differences

    I have three used NOS plates here, all of them have NOS super powershot solenoids attached.

    I want to use the Super Powershot system that is adjustable to 125,150 and 175hp with the flare jets.

    The problem is as follows: all of the plates have different numbers and sizes of holes in the spray tubes. One has 4 small holes per tube, one has 8 small holes per tube, and the last one has 4 big holes:

    The one that fits my application has the 4 big holes per tube.

    Can I use this one with the flare jets and Super Powershot solenoids? Also could you explain the reason for the different holes, and if any problems can occur if either of the shown plates is used with the jets and Super Powershot solenoids?








    Thanks,

    Simon

    The top plate is a non-adjustable Powershot plate. It will not accept jets. It should have brass fittings on it with a fixed orifice. The second plate looks to be a single plate for a 2x4 setup and the third appears to be a Powershot plate that someone has drilled the holes out in the spraybars. I would not recommend that you use any of these plates for your application.

    Thanks for your reply, I really appreciate it!

    What would be the correct plate for this application? How many holes have the Super Powershot spray bars?

    I am not sure what your application is. Please give me more info and I will be glad to steer you in the right direction.

    Built SBF with forged pistons and aftermarket rods, Edelbrock RPM heads, roller cam, Victor Jr intake.

    I want to use the NOS Super Powershot system, as I have all the parts of this kit (solenoids, bottle, lines, WOT switch etc.) except for the correct spray plate it seems.

    Basically all I need is the spray plate that fits the Super Powershot System.

    You will need a part # 12530NOS. It includes the plate, jets and some minor plumbing.
