When To Go To Direct Port
When To Go To Direct Port At what horsepower level do you want to go to direct port instead of dual nozzles for example? Anybody have some real experience with problems running larger shots through nozzles? Of course the type of intake and whatnot matters, but I just want to here some feedback about what people have seen.
There's a few guys around that have run big shots on a single nozzle. With a direct port there's a huge benefit especially with an LSx type intake to be able to tune each cylinder with jet changes. When you read the plugs you can see which cylinder to fatten up by changing the fuel jet.

That sounds like Ken talking right there....
Like Eric said, main benefit is being able to tune each cylinder seperately to get them all perfect, with spraying before the intake, you can't control where it gets distributed. I have no idea if it does or does not get evenly distributed going through the intake, so I can't really comment on that. But I have been running a 300 shot dual stage first stage 200 wet, second stage 100 dry with some good results, and know of others that have had some success with similar setups, so I don't know. But i'll probably switch to a direct port whenever I can get the money together for one and a 90/90 setup, just do it all at once.

Devon, do you run a straight up nitrous tune? I was wondering because I have a dry and a wet kit and I was gonna run the dry first to pull timing then whack it with the wet kit. That would be so I could run a good motor tune and not have to switch at the track.

I know some cylinders are going to be richer that others. My thinking was to am for 12.0-12.4:1 or so on the a/f to make sure there is less chance of going lean in a cylinder. It sounds like there are people running some pretty big shots through nozzle systems.

I still haven't been able to get mine to lean out enough, I gotta play with some things, mine's running at like 10.1
I gotta play with the fuel jet and the standalone pressure some more.

I am on a 200 with a TNT F2 dual nozzle kit. probably fixing to try 250 but I am getting mixed reviews on that idea. with the stand alone we are having a hard time getting it lean enough. I have 200 nitrous pills and 150 fuel pills just to get it on the chart on the dyno
