I just recently purchased a Nitrous Kit and the way it hooks up is It has the Bottle (w/brackets), NOS lines (w/fogger nozzle), external Mallory 110 Fuel Pump, Throttle switch, Nitrous Gauge, and Pills. Now from what I understood and figured out is that the switch will arm the NOS when you hit WOT. Now the external fuel pump he said he tapped into the fuel lines underneath the drivers door side and it feeds for the nitrous only and the injectors feed for the cylinders. I drill for the nitrous in the front of the intake right behind the throttle body and face it ******d so when the air coming in the TB will pull the NOS to all cylinders. Now, the only thing Im having hard to understand is this, if you have fuel going into the engine already why would you want to add more, wouldn't that flud the car? But on another thought, you have the air coming into the intake for the injectors and the gas in the external pump is for the NOS so I guess it evens it out??? That's what I need to understand if that's how it is. Also I have these combinations for pills: (I need help to understand)

NOS GAS Shot
47 53 100
55 61 125
73 82 150
82 91 175

Is this correct? I have in total these pills: 42, 47, 53, 55, 60, 61, 82 / So I can't run the 150 or 175 shots. Where do I get pills at? So would a 50 shot be like 22 NOS/ 28 GAS ????? Because on the chart you see the 100/125 shot have 6 pt increments in the numbers and the 150/175 shots have 9 pt increments. Does this matter or is it just up to the user and what works best? Thanks for all the help.

 

A little confusing..... for starters, what is the brand and model number on the nitrous kit? Did you get any instructions with the kit? If not, did you check the manufacturer to see if they could send you (or sell you a set)? Or maybe they have the instructions on their website?

 

Ok, first you have jets for a plate system. The fogger nozzle is going to have a 75-125 hp limit depending on the model. Sell the external pump to a carb guy and either limit yourself to 75 hp shot, or put in an intank upgrade pump and buy another fogger nozzle to increase the power beyond the 75. Call nos tech for their high pressure jet matrix chart. This will give you your jet sizes for the higher port efi fuel pressure you have. Talk to tech about how to tap into your LT1 fuel system for the fuel solinoid supply. An aftermarket regulator will usually provide you with an 1/8" pipe tap that you can use with a #4 line. This is fine for what you are doing. Do not point the fogger upstream. Your LT1 doesn't have the airflow to utilize an upstream injector and the fuel will end up in your airbox where it will explode like a bomb due to the lean condition. Not kidding. A typical fogger nozzle will support between a 44 and 48 jet, max. Some special nozzles may flow more, but chanxes are you don't have one. Hope this helps some. You'll have to purchase some jets after you receive your chart.
