We will be at track day. If you want a run down on the nitrogen push just come on over and Ill be glad to show you what its about and what you need if you wanted to slap one together.
It basically puts a head pressure ontop of the LIQUID nitrous as it sits in the bottle. The nitrogen must come into another port that does not use the pickup tube. The you need a pressure switch like that from Dynotune.org and then a Dedenbear 3000 psi solinoid. It can be made for about double the price of a good auto bottle heater.
