408 + 300 shot fueling questions got a 408 around 475hp to the wheels . im looking at a 200 dry shot and 100 wet shot ( at once but seperate so i can stage it in as needed. i need to know what upgrades you think i need in fuel system 
got 46lb accels( figure 60lb siemens)
255 intank holey pump
trex inline( was told it is slowing the 255 down take it off)
stock rails and lines
i was talking to a guy about a booost a pump for the intank . not sure how it works or if it will. what do i need? new rail sumped tank? help me out .

This is just my opinion....but I would not do a 200 dry shot...asks a lot from the injectors. I'd do a wet shot and start low on the dyno...say 100 and watch the air/fuel ratio and step it up to 200/250 with what you have...if it starts going lean, stop and add a boost-a-pump and start again. BAP should get you the flow that you need.

i am not willing to go higher than 150 wet shot. i don't want the rear cylanders going lean. I think a dry shot is much safer. i can always get bigger injectors although i thinkl the 60lbs siemens will be fine. I would go DP before going more than 150 wet.

Honestly the problem you are going to run into is MAF limitations with a large motor combined with a very large dry shot. My sugestion is that if you are going to go with 300 hp of nitrous, go ahead and get a direct port setup with a dedicated fuel system for the nitrous. You could add a progressive controller to the setup to get the benifits of the two stage system you are thinking about.
The fuel system you have is great for the motor you are running (- the inline pump).
The dedicated fuel system is great on many fronts, one, great plus is the ability to run a higher octane fuel in the dedicated system. Its also easier to adjust the nitrous AFR, by changing the standalone fuel systems fuel pressure.

Dude just do it the right way.. Get a Direct Port setup... Sell your other kits if you have them, and buy a NX Pro-Shark Fogger kit, or a kit like it. Then do a seperate fuel system, a 1 gallon fuel tank, a holley blue (or black) pump, and the other little things you need.
It will hit like a SOB and it will be VERY safe on your motor. I ran a seperate fuel system even when I had a TNT kit, except instead of a low pressure pump, I ran a Walboro 255lph Inline pump and a Aeromotive Regulator. Worked perfect.

Yeah anything over 200shot I would highly suggest a DP setup! Do it right! 200HP dry may be asking a lot unless you have a really good fuel system or standalone as stated...
