Any Body run Nitrous on their rigs I got a 350 sb and will be running a 100-150hp shot and was looking for Tips on it I got colder plugs good wires , and a better fuel pressure regulator , Who runs it what pressure you run what you got done to your rigs?
rpm window switch and a throttle switch make life easier

window switch, wide open throttle switch, fuel pressure safety switch, keep trhe pressure between 800-1000 psi. I recommend the dyno tune nitrous bottle warmer, it's pressure regulated instead of temp. Colder plugs. usually 1 step colder for every 50 hp shot. So if you are running 100 2 steps colder, 150 would be three, etc. Are you running efi, or carb also? EFI you can get away with running a dry system much easier than with a carb. With a carb you need to run it pig rich all the time, with EFI w/ a MAF system, the MAF will know how much oxygen is coming in and adjust fuel accordingly. With a carb a wet shot is much easier since you can tune it normally and then the extra solenoid will get you the extra fuel. Do a ton of research before you use it since people setting it up wrong is what causes the problems with the nitrous. If you set it up properly you will havfe no problems running that much.

would you run an entirely seperate fuel system to the fuel solenioid
like a small 2 gal cell with maybe Racing Gas? 100 octane+?
i got a wide open throttle sensor , and 3 step colder plus also got taylor wires, and NGK plugs

Depends if you are running a carb or EFI. With an EFI setup it really isn't necessary, you just run a splitter on the back of your fuel rail. On a carb you may want one and then run a EFI fuel pump to keep the pressure at the solenoid. Most setups are meant to be run at a high pressure, hense the fuel pressure shut off switch. Now if you buy a kit that is just for carbs you may not need to. But you will still want a higher pressure fuel pump and run a fuel pressure regulator. Run the splitter before the regulator and then the regulator is only dropping the pressure at the carb fuel inlet.
If you are running a carb, look up some kits in either summit or jegs. Find one you like and once you get it, don't be so quick to put it on and slam the motor with nitrous. Make sure you have everything set up right before you hit it, or you will melt a hole in the top of a piston with a quickness.
with only 150hp you do not need a dedicated fuel supply
