3. The crew at Nitrous Supply drilled our manifold for the system, bent up the stainless steel hardlines from the solenoid valves to the nozzles, and plumbed the system. We then sent the system and our manifold to Induction Solutions to have the system flow-tested and blueprinted. The benefit of doing so was that IS's owner, Jeff Johnson, was able to see what we had for fuel lines and fittings and after flowing the system, he gave us a list of what size nitrous and fuel jets to install so that we didn't waste a lot of time on the dyno trying to dial-in the system. As you can see in the photo, -3 hard lines run from the solenoid directly to the nozzles and interchangeable jets.
