Nitrous plumbing A1A...??..

150 shot and under you are fine tapping into the fuel line to your carb (assuming you already have a good electric pump and sufficient supply). Over 150 I would get a dedicated line/pump/and regulator. The nitrous side is self explanatory.

For what its worth, this is what I did years ago with my cheater system. I was tapped into my main fuel line, running a 150 shot. I had one side of my regulator feeding the carb and the other side feeding the N2O system...tried a 180 shot and it was fine as well, but I was at 5800' (i.e. I had more fuel to spare than sea level folks).

You might want to check out ebay for used nitrous parts. Always been a DIY kind of guy, got a good sized bin full of different plates/solenoids/plumbing/etc that I've picked up over the years to experiment with.

I was going to recommend this. Steve Johnson has a whole nitrous section on Yellowbullet if you drop down on the homepage.

There's also a very good thread on Moparts thats somewhat old now, it mixes in N20 and turbo/blower threads. The sadly missed Nitrous guru Monte Smith answers questions, have a read?. Its 18 pages long and you'll have to sift through to find the N20 threads though.

Same here. Did not add 250 horsepower to my combo, just ran their "250 horsepower" jets. Mine was pretty mild and I never leaned on it hard. Pulled extra timing, ran 110 octane fuel with those jets, and never hurt any parts at all.
Mine was a heavy car and a heavy driver. Probably 4100 pounds or so race weight. Ran 13.60s on motor and best of 11.85 on nitrous.

The opinions will vary. If you are running 2 carbs fog it. Cleaner, softer hit, more options.

As Said Steve Johnson is the man. It's like crack and every hit puts you one step closer to a rebuild lol....

Be cautious on bottles, when they get too old they have to be re certified, that is not cheap. I looked at a bunch of swap meet bottles over the years, they needed re-certified.
Well I found this on Speedmaster and damn near ordered two of them today through Summit... It looks like I can put whatever Jets I want to in them? I would have an extra mounting bracket obviously.. The Summit site says they won't ship them till February 17th and the Speedmaster site says in stock ships within 24 hours? The guy on the summit site said he couldn't answer why..
With the hoses and the brackets I could order solenoids and a Purge kit and be damn near ready for a tank and a line and I fuel system as well?? I know I need the full throttle trigger which I also want to put in line with a trigger on my shifter or something as I want to control it myself...

So I was thinking if I ordered those two plates (post number 32)they would have the mounting bracket for the two solenoids and the purge solenoid? And if I was to get the solenoids and just block them off where their feed lines come in I would be able to run my carburetors normally until I got the tank and line and the fuel system setup? But pretty much be ready...
