    Default Nitrous, plate, spray bars or direct port?

    Following up some of the discussion in the vacuum pump thread, thought I'd start something for NOS.
    In the late 80's-early 90's we ran a Canyon flat in the 8.0 IHBA bracket class (called Super Eliminator back then, think it's Pro E now). We ran a 509 that made [email protected] RPM on the motor. That was good for about 8.30's on the motor. To get to 8.0's we used nitrous. We had NOS install spray bars down the tunnel ram plenum and used jets to adjust for conditions. Typically, we only needed jets nominally set for about 50-60 HP. The jets we used were for 1 cylinder of a Pro Shot Fogger system. Worked great, the boat was a rocket to half track...
    Fast forward to now; we are building another Canyon, basically the same as I ran before. Again for the same 8.0 class. We have a bit more motor now (still going together but I'll be pissed if it's not about 925 HP), but I doubt I'll fly the boat like I used to, so I'm thinking I'll need another small shot.
    Now the question. For a small nitrous tune up (less than 125 HP) would the spray bar in the plenum still be a good way to go? Plates? Seems even a Sportsman fogger will be a bit much. Also, it looks like NOS got swallowed up by the Mr. Gasket/Holley conglomerate, so who does spray bar installations.
    Look forward to the comments.
    David

    I had Nitrous Supply do my Trick Flow manifold last year. 714-373-1986

    I think any of the Nitrous Companies can do it. Just call their tech line.

    CS, For less than 125 hp ? That's alot of beans to put out for that small of a system. But it would give him room to grow, that's for sure.

    My 300 HP spray bar system on the old engine worked great and you only have two solenoids.

    I like the tuning (staggered jetting if needed) and the even distribution you get with the fogger, I also like the easy jet changes and easy maintenence, you can get a nice kit for about 5 bills. Spray bar? I hear the distribution is horrible on those but I have never ran one before so I dont know, just what I hear. We all know that we will always want to push it harder (more nitrous) so why not buy the system that has potential?

    I've got a Victor Jr that we had ported at Wilson that I've considered running a 250-300 shot on. Motor makes 800 now so I think another 300 will be more than enough for me. Is a plate system going to work or do I need to go direct port?

    zex makes a nice 300hp ki that has no bars and i hear distribution is great the way they designed it. i'm runnin a 2 stage plate set-up almost the same way as the zex but it does have a center bar also for the 1stage . my 1st stage is 100-300hp, the 2nd stage is 100-500hp don't think i'll ever be thinkin i should've bought a bigger kit

    But who honestly stopped at the 125 shot? Every one I know thats running the squeeze started off saying there just going spray a "small shot" and are now spraying way more than that.

    If you have the beans I would run the fogger.
    There was a great nitrous issue in the chevy high performance magazine last month. Definitly worth taking a look at.

    Yep Yellow bullet rocks. I think Monty is the man, he knows how to tune nitrous. There is a little spamming going on over there but if you weed thru it there is some good stuff.

    We are trying to hit an index... You only spray enough to get it done. Our last boat went 8.30's on the motor, only needed a 50-75 HP shot to hit the 8.0. The tune up we're working on now we hope will hit the number without NOS, but if we come up short, we'll put a bottle in it!!

    ya I understand that but from what I've seen most people eventually want to go faster and end up spending the money twice. Not saying that you will want to do that but I can think of numerous people (including my self) who that has happened to. All I'm saying is if your willing to spend a little more cash then go w/ the fogger that way you atleast have the option. On top of that they are much easier to tune and look insane
