you DONT want the nitrous to FOG in the airbox and change the relative air density, air temperature,humidity or barometric pressure IN THE AIRBOX... WHEN you shoot a "positive pressure" (compared to "ambient pressure") you change the WHOLE science of carburetion and throw it out the window... the CARBS will NATURALLY create a LEANER condition (because of the pressure ALONE) not to mention the NITROUS'S 02 content.. and cause the WHOLE SCIENCE of carburetion OUT THE WINDOW!!!! NITROUS systems work BEST when you spray nitrous and fuel into the CASE!!!!(usually at the crank)!!!! The fuel and nitrous need TIME TOGETHER (especially with the HIGH OCTANE FUEL) go "get to know each other" (if you will) so the fuel can atomize-vaporize (whatever you prefer to call it) so the mixture can enter the combustion chamber to "do it's thing"!!! I've met and talked to Barry a few times and MOST of his ideas impress me... Some don't!!! I'm sure he feels the same way about me and my ideas!!! BUT thats O.K. If you want to talk to srx2000, he'll talk to you and tel lyou ALL ABOUT NITROUS just like a LOT of guys out here on this forum!!! If you want me to endorse a system that is available to the general public,,,, SRX2000's system would be MY PICK....... Gary Oles nosboy
