5177 Dry Kit Open Line HP??? First off is this stupid to run this kit with no jets. I heard that it puts down about 140hp@ the wheels. I am kinda new to nitrous. I have a window switch, low fuel pressure cutoff switch, and WOT switch, and my bottle stays around 1100 psi with the heater and bottle pressure switch. I decided to hose her down tonight and man it felt good. Then I thought anything that feels this good has to be bad, thats why Im on here asking you veterans. First off I do have HP tuners and am going to try to get my A/F down to about 12.5, right now it is close to 13.8 to 14 range which might be a little lean to be spraying this much. I do not show any KR however so I dunno?? Help me out guys, Im a family man and cant afford to melt my block.

Ok I see, Im an idiot, thats the A/f it changed to, 11.0 when the MAF picked up on the nitrous. and its normally 12.5. Ok. I dont know why my car is so lean. Im gonna get back on the dyno and get some more results. I only went once and it was 14.0 and 13.9 across the board from 2500 Rpm up to 6000 Rpm.

Also check the type of A/F meter they are using, I had one shop slide a sensor in my exhuast tip, and i still had cats, so it said i was running 15:1 or some BS. After i got my cats off the car, i went to a place where they actually remove a 02 sensor and replace it with a wideband, there i was 12.5:1 NA. and so on. So just be careful and watch how they monitor your car.

Ill get this A/F thing handled now that I know what a couple of others are running, and what you all are telling me seems consistent with what Ive heard.
Now does anyone know anything more about the 5177 dry kit. How much juice is it spraying without jets, no jets, notta. I know a few peops who sprayed this kit this way and one has a blown motor, of course he sprayed it like that bottle after bottle for 142,000 miles. lol. So I just wanted to hear what some of you others had to say and what power level you heard it was.

Not sure on this one, But i think the main restriction at that point would be the solinoids, if your using the small ones, i believe they are only rated at like 175 each for Max, so you might top out at like a 200 or so, no idea. If your running the larger solinoids, then I believe Homeslice calculated a 325 shot, or some **** like that with no jet.

Thats Fin crazy dood. I think I need more fuel maybe even bigger injectors and fuel pump to spray that much of a dry shot then. I didnt think about how big of a shot it was, just knew some peops were doing it. I guess I need to follow them when they jump off a building too then. I think I better stick to the 100hp jets til I get some more upgrades. Sux, that big spray felt good too.

Thats cool. My kit only came with 75,85, and 100 hp jets. Dude, the open line felt good, and my bottle heater wasnt installed yet, only runnin about 850 psi, it will be 1100 with the pressure switch, that would hit hella hard, time for more fuel

I spray my 5177 w/ no jets. I have it set up exactly like the manual says except with no jets, notta.. 
I started with the small and so on, got bored with the big jets, then took them out. I have a 98 with the larger injectors, and I haven't had a problem with detonation yet!

DOUBLE THE OUTPUT

Yea, on a 5177 with redundant n2o noids the limiting factor is the .076 orifice in the noid liminting output. Each nozzle has an orifce of about .087, so if you split up your noids one to each nozzle you can double the hp output of this kit. Being funny?

That's actually what they did to my car. They slid the sensor into the rear of my exhaust, but I have cats. Was showing that I was about 14:1 when I sprayed, so I shut off the spray to prevent any possible damage. I was told to come back when I got the A/F down to somewhere around 11.5:1 (12.7 on motor). So maybe the cats are my issue? I was spraying a 120 shot (dry).

No dude, not being a smartazz, just trying to imagine what a open line would feel like with the noids split, that is if the engine held for even a second.
