hey guys im new to nitrous and jus bought a edelbrock performer kit to run on my small block chevy..I was wondering if a carb system needs to be purged cause wit the spray bar plate im assuming it is jus being sprayed right into the intake manifold..also if u can run one how hard is it to install cause it is a pretty cool thing to have lol

 

If you have a kit, you always want a purge just to make sure theres no air in the line. Its easy to install, goes inline before the actual nitrous solenoid.
