Hello all, I'm looking to put nitrous on my engine. I am wondering what the pro's and con's of a fogger vs a plate system are? I have a 548 bbc in a jet boat, looking to spray about 300hp. Working my way up starting, off at 100hp. I don't plan on officially racing it in any kind of events, and I don't anticipate that I will be using it alot but of course everyone says that! I have heard both pos and neg things about both, but I want to hear what everyone's real world exp has been with each and not theory. So with that being said, what do you guys run and why? Also if you could do it over again would you make the same choices? Thanks.

My old manifold, you can have the spray bars installed in the plenum pretty clean system:



Can't find a picture of the new intake :)bulb

Maximum adjustablity is a fogger, but this system puts out over 300 hp with 1 fuel and one Nos siloniod.

Have you ever dynoed with an a/f in every cylinder? Alot of single four barrel manifolds don't distribute very evenly. When running nitrous it can get ugly, with a port system you can compensate for it.

Oh it can get ugly all right:



Wall of Shame tokens

( don't drink and drive ;) ) staying on the button for longer than I should have had some to do with it.


After this happened the second time I had the bars installed in the plenum never even hurt a spark plug after that. Should have done it two years earlier when I first thought about it. Must have been in '95 or so, maybe earlier.


Having the bars in the plenum fixed the distribution problem. When I got the new manifold it got the bars installed after the porting was done, before it even hit the water.

thanks guys for the input, yeah I've heard that a fogger allows maxium tunability but I have also heard that plate systems today have came a long way since the days of the past. With that being said I have also heard that in a harsh bumpy marine enviroment it's a lot easier for a fitting to vibrate or rattle loose causing a leak and wreaking havoc, also you have to worry about every nozzle in a fogger performing flawlessly, if one malfunctions for whatever reason your done. So I like the simplicity of a plate but concerned about the aformentioned distribution issues! The spray bars in the plenum sounds intriguing, but I have to believe that they cause some sort of impediment or distirbance to the airflow? Keep the input coming guys, thanks.

something you'll never see on the tach or mph on the water, dyno........maybe but not enough to effect the performance of your boat off the button.

If you arent going to run a big shot of nitrous then a plate will work fine and is easy to tune. If you want over 250hp I would use a fogger system.

Have had real good luck with the nitrous express billet plates- 300hp no problem- but all on cars-
never juiced a boat- just prefer blowers on my boats I guess:p

NOS systems have a few extra rules

First the fuel system must be top of the line no short cuts

Second the spark and timing also must be able to handle the demands

Pistons don't last long when you miss the mix

Hey sleeper cp, I was wondering where can spray bars be bought from, and how did you install them?

I think any of the major Nos Companies will install them for you, not sure if they will sell you the bars to do yourself.

NOS systems have a few extra rules :

1st: there are two types of Nos users, those who have blown-up shit and those who will.

2nd: the fuel system must be top of the line no short cuts

3rd: the spark and timing also must be able to handle the demands

Pistons don't last long when you miss the mix
Corrected.
