Standalone vs taking fuel from rail
Standalone vs taking fuel from rail Whats the pros cons of running a standalone system vs from the rail. Im running a 200shot n.o plate kit wet. Is it worth the extra money? Will i be fine and safe just running it with taking fuel from the rail?
Standalone
No Fuel pump upgrade required
you can put race gas in the tank for safety
No risk of having some injectors go lean from pulling off the rail
Costs $$$$
I spray a 250 shot on a heads and cam LS1 off the fuel rail with no issues and a walbro 255.

As mentioned above if you run a stand alone system you wont have to worry about the fuel pump in the car being able to handle the extra HP or having fuel pressure drop for that split second when you are spraying a large shot.
One of the biggest benefits of having a standalone is that you can run a high octane race gas in the cell so that you can get away with more timing without having detonation problems while on nitrous.

As mentioned above, standalone. It's much safer on bigger shots and you have the advantage of running a higher octane fuel in the cell.
I have run a 250-300 shot pulling off the stock rails with a 340 pump and a hot wire kit. I wouldn't necessarily recommend it but I made due with what I had.

I think it would be easier and more cost effective if you just ran the standalone. I think you will be fine running a 200 off of the rail. The only way to truly tell is to read the plugs and see if you are going lean in any cylinders.

another benefit to running independent fuel for the N2O that has not been mentioned is it is very important to keep psi consistent not only bottle pressure but often overlooked fuel pressure. additionally running independent allows you to run lower fuel psi and thus a little larger fuel jet compared to EFI fuel psi. the jets get very small on lower size shots and the smallest particle can obstruct the fuel jet and things go bad very quick. personally i rather run a lower psi and larger fuel jet also it allows your fuel pump to run under less load at lower psi.

I am planning on running my nitrous fuel supply from a y fitting before the rails, with an Aeromotive A1000 FPR after the rails. I will be running a 200 shot. I will also be using a KB BAP as well. When I get the money, I plan on spraying meth thru the plate along with my nitrous, but that is down the road lol.
I should be about 550rwhp on motor (11.5:1 compression), throwing the 200 shot on top of it.

You should be reading plugs anyway or your just guessing and risking buying a motor.
If you get a fuel cell, look into the ones that go next to the fuse box verse the battery located ones. Im new at this to and got a used nos kit with fuel cell that goes where the battery is, so than I got a battery relocation kit, battery box and so on. Its only money that's all

good advice for any guys new to nitrous is start with the smallest jets you have then learn to read the plugs. if you start with 75-100 apx Hp jet and can not tell or explain the difference or effect of appearance on the plugs timing marks and fuel ring you have no business going to larger jets.
also be aware that idling and the short drive back to the pits/ nearest parking lot will skew your plug readings shut down asap after your run and get a tow back if at all possible. This makes for the most accurate information from the plugs and allows you to learn how to read plugs much more quickly it has for me anyhow.

If you can go dry nitrous imo. Seems people have decent ways with HP tuners and EFI Live plus most if not all new standalone have that option and a progressive built in. The fastest LSX nitrous guys are doing dry just saying.
