NOS problem in my GT-Four Options

[Vacchus]

Yesterday i had a street race against a sierra cosworth rs500 and while i activated the nitrus beck the tube nearly exploded! Thank to my mechanic i had an extra safety valve that propably worked and stopped the nos supplyment to my intake. Some people there told me that propably this happened because of overheated intake, but i dont think that the temp was so high to cause this problem, and in the past i have use the nos, with much more temp. Does anyone know something about this problem or had something like this in the past?? I dont want to know what would happened if the 10 lbs of the bottle would explode, but i dont want to loose the extra (just in case) boost!!
Is there any website with a specific forum about the nitrus oxide systems, or some advanced informations about troubleshooting??
