not sure if this is the right place or not but I had an idea for my project.
Is there a way to wire something to come on at 1800 RPMs? on my boat i want to wire a water valve solenoid that will let water into the headers at 1800 rpms. kinda like a NOS switch i guess. Is this possible?

A window switch is designed for anything, not just nitrous, so that would be my vote.

I'm thinking an rpm activated switch that comes on automatically at a given rpm everytime and shuts off under that rpm no matter what

Not through the MSD 6012/10 box, you'll need a dedicated RPM or window switch as noted.

Sort of like a shift light.

A window switch, that is whats needed.

forgive my ignorance wiring is definately not my strong suit. But are you guys refereing to a momentary switch like for a power window?

No, a window switch is setup to activate or deactivate a accessory from a given "window" of RPM you wish to start and end.

Hahaha that makes way more sense!!! Is that activated by the tach or by the crank?

Usually by the tach signal.

Here's a couple examples, first the old-style (uses pills to set), and now the new digital style. Let your wallet be your guide...
