You can spray thur the blower no problems.

With stripping off the teflon, its debatable. My own personal car i still have all the teflon on the rotters. Dvldoc who has ran just as much thur his car they are cleaned off. Just like its no problem finding someone who never ran meth or nitrous and there rotors are clean. IMO it just happens to some and not to others.

DevilsOwn Injection is the solenoid we sell. I recommend running our check valve. Its cheaper and works without any problems. Reason why thats what we supply with all kits. Sounds like you got it all setup for what you need.
