The blow down tube is only required if the bottles are mounted in the passenger compartment. If you have them in your trunk with a backseat or firewall seperating then you will be fine with the supllied burst disc set-up.. Something to pay attention to is when you are installing a blow-down tube DO NOT overtighten it, the burst disk will be become weak and blow off too soon, I have been in a car where this has happened and its not fun.
Man, that is a great install on those switches. Is there a company that makes those plates or did you make it? I have seen the ones that go in your cup holder but I like the OEM look for the interior so the way you have yours setup is very clean.
Nice pics man! I appreciate your guys' help on this. Do all these kits have the WOT switch or is that another option for the kits? I really am uneducated on nitrous. I don't even know how the kit works. I'm assuming that you just turn it on, warm the bottle, purge the system and then it activates at the RPM levels programmed in your window switch? Lol... and what exactly does purging the lines do?
All kits come with a wot switch, it's what tells it to spray once the system is activated. Purging just clears the lines out so you get a consistant spray. Open bottle, start heater, wait for pressure, activate system, purge, and make a pull. All your switch tell it when to spray and for how long.
