Something has been bothering me about how nitrous is hooked up on a fuel injected motor. My brother has a big block chevy with nitrous. He has a separate fuel system for the nitrous and always double checking the fuel pressure to the nitrous system. Adjustments are done with a regulator (of course). He says that without the regulator the fuel solinoids would stick open. On my TNT kit for my 95 firebird, the fuel line for the NOS just plugs into the schraeder valve. Are solinoids on fuel injected systems designed to handle the high fuel pressure? I know 44 psi could not be handled by the solinoids my brother uses.
Any ideas?

LOL
How do you know his solenoids won't handle the N2O (not NOS!)?
The solenoids are the exact same.
You just have options on bigger higher flowing ones. They will work for high fuel pressure or low.
Your nitrous solenoids work with pressures near and over 1000psi and are built just like the fuel ones (basically).

Answer your question?

"How do you know his solenoids won't handle the N2O (not NOS!)?"

Was referring to the fuel solenoids not the N20 ones.

 

He was basically saying the noids are the same. So if the n2o noid can handle a 1000psi then 44psi on the fuel noid is nothing...

Well, like Ken said..I know what you meant.
I know about the Noids, because I sell NX.
They are all the same (besides size/flow rate), from kit to kit, doesn't matter the pressure against them.
