Seems like I am still having a issue with the nitrous, hitting extremely hard. You can feel hit just not like a ton of bricks.

The fuel is Sunoco 116 45psi, NO pill spread is .62/.23 for the fuel side. It still rich 11.0/11.2 it doesn't seem right. Being race gas I would think that the car needs a bigger fuel jet.

Motor runs are 12.4/12.6 all day everyday.

Car went 11.1 on motor at MMP and with botlle went 10.6 last night I changed the fuel pills to a .18 and left the .62 on the big side and weather rolled in.

Does that not sound right to anyone else

Have you tried dropping the fuel pressure? Run like 5-8 psi and you might even be able to jet it straight up. I always worry about really small jets clogging, but that's another story altogether. The lower fuel pressure should give you some more fine tuning ability vs 45 psi. My .02

Are you sure those are the jets on the car?

.062 Nitrous/ .023 fuel?? and then you said you went down to an .018 fuel??

That should be really lean at 60 psi let alone 45 psi. Something is going on here

How did you set the pressure on the stand alone? Did you set the pressure flowing with a jet in the flow tool or did you set it deadheaded? I am guessing that your gauge is off because NO calls for more fuel jet on their plate @ 45 psi than they do @ 55 psi. Their chart calls for a .035 fuel jet with .062 nitrous so you should be way lean with .023. I am thinking you have way more pressure than 45 and don't know it.

Yes I am sure if the jets, I changed them myself last night .62 in the top, and a .23 for the fuel. Only reason I changed the .23 to a .18 is that is was 11.0-11.2 on the wideband. So to lean it out I dropped to a .18

The fuel pressure is static not flowing, and fuel pressure is set with the regulator on the standalone, gauge is on the manifold pre solenoid

Pressure should be set flowing .

I will set it tomorrow flowing tomorrow and reevaluate the issue. Thanks

I have a similiar issue on my Nitrous Outlet dedicated - on 078 N2O jet I had been running 36 fuel jet and had to drop fuel pressure in dedicated down to 38 llbs and was still rich (pulled plugs). Had to drop down to 34 jet so I could increase fuel pressure away from fpsw set at 35 psi (increased to 40 llbs). I don't know anything about setting the guage flowing or static but I am very interested in following this thread to see outcome.....

I mean I can eliminate the standalone from my set up, and pull pump gas off the rails that are a constant 58psi with enigine running, then I can see if it is a standalone issue or the solenoid on the nitrous side not opening or a nitrous delivery problem. Which I don't think is as I replaced the main feed line already

The issue is not the dedicated. Its just simply supplying fuel to the solenoid.
Are you street tuning the system or on a dyno. If on a dyno is it making the power?

What does all of your system consist of?

I wasn't implying that there was a problem with your stand alone system other than he may not have set the pressure correctly which was making the tuneup, jetting etc incorrect. I have one of your stand alone systems myself.

NO outlet 102 truck plate, NO solenoids, No standalone and msd window, you guys did the hard lines.

Street tuning don't want to waste 100.00 a hr just to have to find out its still not right

Killer 5.3 I know.. I was replying to Sean.

What happened when you tried the specified jetting from NO? explain the process that led you to that .023 jet please

RsSean

So rich is choked in its self, so we dropped the fuel pill till it actually ran in the 11.0 in the wide band.

But have a good learning phone call from Dave we think we have eliminated the plate and nitrous side as being a problem.

I had a bad lean issue when I first setup the nitrous on my car. The air fuel was fine on motor but no matter what we couldn't get the air fuel right on the bottle. I would go waaaaaaay lean. It turned out the throttle body was not sealing completely against the intake. It was enough to be fine on motor but not when we used the bottle. Had to grind the water pump down a little more and it was fixed.

I put a Nitrous Outlet plate kit on a 2010 Camaro with a dedicated nitrous fuel cell and was really rich also with the recommended jets. I ended up running a 78N 33F(200 shot) and lowered the FPR on the dedicated from 58psi to 48 and just left it at 11.8 AF.


On my truck I just finished some runs using a 88N 33F with fuel off the rail at 58psi and was 11.2 AF. I run the NANO system on both vehicles and B8EFS plugs. After dialing it in as best we could I pilled it down to 56N 22F for DD and it was in the low 11's AF.


Going to switch to E85 and turn it up to 300 shot(93N) tomorrow so I can be ready for the next track day. I just saw the jet chart for E85 and it looks like I have to up the fuel side a little.


Should I step down to B9EFS plugs?
