    Default Nitrous Question

    So I am putting together a motor for the boat, it is a long rod 454 .30 over with forged I-beam connecting rods, SRP forged pistons, and a forged crank. With the domes on the pistons and my open chamber GM 990's I am right around 9.5 to 1 on the compression. My goal is to run Nitrous and my questions is, is there a benefit to running a fogger system in the intake over running a plate kit below the carburetor?

    I am thinking about a 250 shot on the boat will be about all she'll handle for any period of time. I would like to keep the boat engine together for a while, the nitrous will probably not be on the boat for a couple of seasons so I have time to set the cash aside and plan my system. Thanks!

    Better distribution on a fogger- Due to each runner having its own nozzle each cylinder gets the same amount of n20 and fuel where a plate system is sprayed into the plenum and kind of travels where ever it wants. A fogger is also easier to tune because you can tune each cylinder individually.

    things to think about when building a juiced motor.
    Rings and ring gap
    wristpins need to upgrade with a 250 shot for sure.
    bearings buy good ones.

    A plate will "hit" harder from what i have seen and heard. reliability and adjustability go fogger.

    Ther is so much to the nitrous thing. I have only begun to learn and im still really confused....

    One of the biggest differences $$$$$$$. Quite a bit more expensive to purchase the fogger kit due to additional components in the kit. Then you have to figure in the cost of intake modifications (drilling and tapping for nozzles), or at least the cost of the hard line and fittings and the time it takes if you're going to do it yourself.

    If I were going to do a kit for a lake/river boat and knew it wasn't going to get jetted higher than a 250 shot, I'd do the plate/plates. That's just me though.

    I'm running a dual plate with a tunnelram and have had it on the boat for about 5 years and it's worked just fine. Only jetted for 150 hp though. The only problems encountered were a broken microswitch on the carb linkage and a failed solenoid. Easy fixes and I carry spares now.

    Another thing to keep in mind is when running a 250 shot you should really be running race gas (110 or better). I can get away with 91 pump gas with the 150, but any higher than that and it should have better gas. This is one of the reasons mine's jetted for the 150. I don't like having to pay the race gas prices, or make special trips to get it. Also doesn't require a timing retard box/module unlike the the 250 shot.

    Some of these guys that run the real nice (big) kits will have better information. Like I said, for what I do and the way it's used.....mine works fine.

    I wouldn't hesitate to run a 250 shot. Later down the road put a better top ring in it maybe open the gaps depending on what they look like and check the wrist pins out. Have fun!

    I am running a set of total seal rings, they haven't been gapped yet. I was planning on having a seperate tank with 110 for the juice runs, haven't fully planned it out yet.

    Let it rip! I agree with cs but make sure your timing is ok.

    Do you just plan on running race gas as the enrichment fuel or a separate system ? I'll assume just enrichment fuel and as CS stated a 250 shot will be fine. My system runs methanol as the enrichment fuel; less detonation and for the same amount of Nos run (jet size) it will produce more power.

    Just remember there are two types of Nos user's, those who have blown up shit and those that will. But with a big shot it's sex in a bottle, the shit will curl your toe's.

    Thats exactly what I would like to avoid... I am a motorcycle rider and we have a similar saying, and boy that shit hurts!

    That being said, I will probably be collecting parts for quite a while so I have plenty of time to carefully plan out my mode of attack. Hopefully by the time the boats on giggle gas I have a second engine sitting in the garage for it.

    Methanol is a great idea for an enrichment fuel... How are the costs between that and race gas? And how and where are you getting your methanol?

    Just use E85 for the enrichment fuel....! Lots of good info over at www.yellowbullet.com on nitrous! Monty runs the site as is one of the best nitrous tuners and well as Steve Johnson from Induction Solutions is on that site and he is one of the best!!

    Not to say that there is not any great info here but all the big hitters and tuners are over there. Chris (cs19) hangs over there as well and can vouch for whats there.

    Good luck, Nitrous is a wonderfull thing to play with when its done right!

    Do you have to run a electric fuel pump?
    Can you keep the manual fuel pump? which I like.
    Do you tap into the same fuel line if your running a manual, for the electric to feed the nos?
    Does n.o.s make better solenoids then they did 20 years ago?
    For a dual plate system, what would you guy's consider?
    Sorry LuckyDaze I was going to post up something on NOS info but you beat me to it. Didn't want to start a new thread about NOS.

    If you go plate you might want to get something a little higher quality like wilson or speedtech not sure if edelbrock has a plate or not but they make nice stuff. Keep in mind their tuneups are nowhere near where they need to be. Do your homework, learn from others mistakes and you will have a trouble free system and make alot of power and you wont hurt a thing. Always remember that rich is not safe and to burn it up from being lean is hard to do unless something fails.

    As you get closer we can help ya get dialed in, if you have questions just ask and we will try and help ya out.
