Nitrous plate should go UNDER the spacer for sure , if you're ONLY spraying a 100 shot then pull around 5 degrees & work it back in if the plugs tell you so , should be fine on the fuel you normally use , if the plugs are projected tip then change them out , NGK are a good nitrous plug.
Buy the system as a kit , mismatched solinoids don't fair to well if you have'nt got a handle on the tune.

The instructions for my NOS Super Powershot on page 13 says to use the 2* per 50hp method and test against the plugs and MPH. Is this bogus info?

The plate should go between the adapter and intake, NOT above adapter. Forget the 2* per 50 hp for retard numbers, the timing number that the motor runs N/A has no bearing where it will run on spray. Where timing needs to be on spray depends on how much you spray, how much compression you have, what head you have, what fuel you run, what plug you run, among other things.

Thanks for answering Monte.. Was hoping to get so insight on this from you. It's a 440-1 headed motor right at 13 to 1, I'm thinking bout 100 or 125 shot.. I'm running VP C12 fuel, I'd have to look at the plugs that are in there but their middle of the road Autolites..

The info on that sheet is better than no info at all if you're a beginner , although 3* per 50 would be a safer starting place , only the motor will tell you what it wants , these timing #s quoted are just a starting refference & not set in stone , i pull 6* on a 300 hit , 9.5 to 1 with around .100 quench , the 2 per 50 rule would have me pull 12* , my other motor wanted 10* on a 200 hit.

Let me say one more time, the timing number that your motor runs best N/A has absolutely no bearing, where it needs to run on spray, so the "x" per hundred, or fifty, or whatever, is useless. Let me put it this way, lets say you have two nearly identical motors, but for whatever reason, one liked 32 degrees and the other liked 40 degrees on motor. If you used to "2 per 50" rule, motor 1 would be at 24* with a 200hp shot, motor 2 would be at 32* with a 200hp shot. Motor 2 is not going to be happy, as that is too much timing, for a properly tuned 200hp shot. This is an extreme example, but it shows why the "X per hp" rule, is about the dumbest thing they ever came up with. This gets more people in trouble than anything else. As far as "that is what is in the NOS catalog", well, not for long. New catalogs and instruction sheets are being printed and a new way to arrive at timing numbers is being included. I know this, because I wrote the new instructions and tune ups, for the new catalog.

So you spray a 150 shot after removing... lets say 9* of timing for example and the plug is still pig rich.. you would? I think im gonna spray later in the year.... my car I just bought is wired up with a 3 stage retard system.. have no idea how to use it yet...

Over time i've found the 2* per 50 hit does'nt always work , in saying that it worked pretty well on an old 440 i ran , the 605" i run now likes around 1* per 50 hit (300 shot) if you base it on timing pulled per 50 shot , when i sprayed it with a 200 shot it liked 1.5* per 50 , so you can see with this engine the more i spray the less spark lead needs to be pulled , if i step up to a 500 shot then who knows , it might start going the other way regards timing , guys new to this have got to start somewhere & i found the 2* per 50 WAS a good starting point when i running the cheater plate , if the fuel you use is the correct rating & the plugs are right for the ammount of spray you're gomnna be using then i don't think pulling 2* per 50 is gonna hurt the motor when spraying around 150/200 shot , just gotta read those plugs after the first 1/8th make pass & go from there , you may find the motor wants more or less timing , @ least you had a starting point ,& yes bigger hits are a different ball game , but by that time the begginer should have a hadle on it.

when are the new catalogs going to be ready?

Listen to Monty. I ran all kind of combinations that always resulted in N2O backfires. Needless to say I rebuilt and even bought a couple Dominators and a new set of Dart Pro1's before I got wise and asked the expert to set up my combination. I tried running the 2* timing. My 468-9.5/1 on the dyno made 658hp on 110 @ 37*. Put the N2O and the right combination works at 22* for a 125 shot. I have been using Monty's set up for better than 200 rounds and no I will be sorry for saying this) issues.
1/8@5.83/120mph
1/4@9.28/143mph

Was that a typo error? , you're saying you pulled 15* on a 125 hit? , either you left some power on the table or the motor had wayyyyyyy to much spark lead on motor only , i pulled 15* on a 300 hit & blew the throttle plates off the carb , this was due to crossfire in the cap , have since changed it out for a different cap.

If it is rich, you remove fuel, or add nitrous, rich is not a timing issue. You CANT force a motor to burn more fuel than it needs by adding timing. If its rich, its rich.

Obviously I can't tell you what to do, but I wish you would please stop suggesting these timing formulas. They don't work. Even your own examples, don't work, so why quote them. This is not goood info for a beginner.
