Well guys, drag racing season is starting to come around, and my next few paychecks are goin' into a nitrous setup. I want to run a TNT F1, or NX GM EFI kit. Besides colder plugs and a window switch, what all do I need to run a 100 shot as safe as possible? I assume I'll need a bottle heater too. Also, what exactly is a blow down tube?

I want to do this right and run the nitrous as safe as possible.

Thanks in advance for any help
Matt

 

Get a fpss and nitrous filter for safety reasons. The blow down tube is a tube connecting the saftey rupture disc of the bottle to the outside of the car. In case the pressure of the bottle increase to the point were the disc is ruptures, then the n2o will escape to the outside instead of in the drivers compartment.
