FAQ:  DANGER - Nitrous Express
How NOT to use Nitrous Oxide!

Warning by Geoff Mohler

Nitrous Oxide systems can give racers that "extra edge" that may put them in the winner's circle. Our own Jack T recorded the fastest 1/4 mile time EVER for a Stealth or 3000GT using a Nitrous system. Handled and installed correctly, they are reasonably safe, but this is one system that we should avoid of, IMO...

This example was a badly-installed Nitrous Express kit (not to be confused with the NoS brand). They wired up the heater directly to 12v (not on a temp switch) and left it on. Then they had TWO pressure release vents on - instead of one - which doubled the emergency release pressure. The car owner claims a malfuntioning safety valve/disc/cap. (?) And below you can see the results.

Fortunately the car was garaged, so no one was hurt. This wasn't a 3S car (it was a modded '91 Nissan Maxima owned by Doyle Thomas S. of Ohio). But these photos bear looking at, just so you know what you're dealing with when you consider adding a shot of Nitrous. This was a professional installation on a spotlessly clean engine, with the bottle kept safely (?) in the trunk!
