My poor Nitrous Outlet nitrous kit has been through the ringer...

First, was a DRY nozzle kit, to help (or should I say, TRY to help) spool my old rear mount turbo...

Sold the whole turbo setup and converted to a WET nozzle kit....

Couple days ago, Ebay had a 15% off everything sale, so I ordered a Wet Nozzle to 92mm Plate conversion setup....

Mainly, I do not care for having the nozzle "mounted" into the silicone bellows (speed density car)

But am wondering if the PLATE(with it's better distribution), should, jet for jet, make about the same, or more HP?

On a side note:
With a 200hp n2o jet, I run a 150hp fuel jet, and still see AFR no leaner than 10.8:1. I am hoping for better adjustability with the plate as well.

Should be about the same

brandon@nitrousoutlet

iTrader: (2)

Yep. It should be fairly close. Report back with some results!

I will. Plate has been on, and bottle is full, but weather has not cooperated at all.

Well....appears to have been a $300 lateral move in my case...What sucks is, while the plate cleans up the "looks", with the Dorman LS2 intake and 92mm TB, I have had to trim the heck out of my bellows to make room for the 3/4" wide plate...so if I delete it, and go back to the nozzle, I need a new bellows, and a new purge line... .

anyway....
Nothing different but the Nitrous Outlet 92mm plate replacing the Nitrous Outlet wet nozzle...same jetting, as recommended by manufacturer's jet chart...

2/10th's and just shy of 2 MPH slower...car runs near identical incrementals footbraking or using transbrake, but I always mix it up and use both everytime

It was a half point RICHER though, according to datalogs...
HPTuners logs usually are 10.8:1 at WOT (which I think is already too rich)
Last night, I saw as low as 10.3:1...but unfortunately forgot my jet box... (78 nitrous/35 fuel, 200hp, is what I had in there)

I "HOPE" it was just a weather related decrease, and not a decrease strictly due to the plate versus the nozzle...

I don't know where to locate a weather summary from 3 weeks ago, to compare to yesterday's...in fact, can't even find one for yesterday, LOL

I think next time, I will have the nozzle back in the mix, and make 2 passes with it, then 2 passes with the plate, same day, same weather, same jets, and get a better comparison.

Lean that thing out man! The jet chart numbers are only a rich starting point. You still have to tune on it from there. 11.8-12.0:1 is what I would shoot for. What size line are you running from the nitrous solenoid, to your plate/nozzle?

iTrader: (43)

Oh, I know it's beyond pig rich, LOL...I didn't have my jets with me, and the fuel shack guy only had NOS brand jets, which were different.

I am using the, as-delivered, -4 from bottle to solenoid, and -3 from both solenoids to jets (plate or nozzle)

You've got a restriction with that 3an line. A 3an line will tap out around 175 hp. You need what's called a "race" hose. It is a 4an line with a 3an b-nut on one end. Check out the link below. You will also need an 1/8NPT X 4an fitting for your nitrous solenoid outlet.

Story of my life...
I started with an X series DRY nozzle kit.
Then converted it to a WET nozzle kit.
Then finally, converted it to a 92mm WET PLATE...so probably already over spent by $100 (give or take) as opposed to buying the NON-X series wet plate (and it's included "race" hose and bigger solenoids) from the beginning...(which is 100% my fault)

I now see that the X series nitrous solenoid only has a .078" orifice, so to up the shot to what I wanted to, I'd need the bigger solenoid and the race hose....dammit

I guess I'll either just settle with a 150 shot, or try to sell what I have, minus the bottle, and spend $700 on the better wet plate kit...

brandon@nitrousoutlet

How high are you wanting to go? You can still get 200 out of that .078 solenoid. The nitrous jet for 200 is a .078.

iTrader: (43)

400, of course!!
....sheesh...LOL...j/k

I wanted to try a 250 shot. I think that (and my needed fuel tuning) would get me those last 2/10's to run easy 10's...heck, the 200 shot would probably have done it with a more realistic AFR. (It went 11.20's at 121-122, 4 in a row, with a mid 10:1 AFR...with 78N/31F jets)

Well, I actually had a couple jets, and the "race" hose in my cart, waiting until I had a chance to complete the order, and instead found a mostly complete Nitrous Outlet 90mm plate kit, with the much bigger solenoids, and the hard lines. The kit specs say it is capable of 400hp with additional jets, so I'd assume (hopefully, correctly) that a 200 or even a 250 shot, will easily FLOW through the included hard lines, since the advertising for the kit says it is capable with nothing more than jets??

Planning to use the new solenoids, hardlines for Test & Tunes, and if what I have now can't fetch me $300 or so, I'll re-install the wet nozzle with 100hp jetting for bracket racing....using the plate strictly for N/T fun.

Sweet! Just make sure it has a 6an main feed line. Some of our earlier systems were sold with 4an.

rel3rd

iTrader: (43)

This has the -6 feed, but will I need that at 250hp?

It has the ProMod Nitrous solenoid...

brandon@nitrousoutlet

iTrader: (2)

That's a newer system. It will have a 6an feed line

rel3rd

iTrader: (43)

Sorry. I should have clarified...

I only bought the kit incomplete...no lines, no bottle

it does already have a -6AN fitting into the N2O solenoid, but will I "need" the bigger line to feed a 200-250 shot (max), or will my existing -4AN line support 250? I'd much rather buy a new solenoid fitting, than new.line and bottle nut, and also have to reconfigure my existing -4AN purge setup...but will if its recommended.

My end goal is to use the plate and newly acquired big solenoids for T&T and N/T fun runs, and use my existing X series solenoids and the wet nozzle (if needed) for bracket racing...but 100% NOT as a dual stage setup.

brandon@nitrousoutlet

iTrader: (2)

Yeah, I would switch it over to 6an. The longer the 4an line, the less it flows. Could a 5 foot 4an line flow 250? Probably. But, a 16 foot 4an line, wont be able to move enough.

iTrader: (43)

Good enough for me. -6 it is. Thank you.

iTrader: (43)

Just to update....

-6 line and higher flow capable solenoids DEFINITELY make this same 200hp shot hit harder.

1st pass last night, spun bad (which it never has done before), with nearly a 1 second recovery, still went 11.43@123, but was a bit lean at 12.8:1 AFR (78N/28F) through the traps.

Swapped in 35 fuel jet, as I had nothing between the 28 and 35, and it brought the AFR a lot closer, but a little rich now...

2nd pass, hooked great, pulled the front wheels and a 1.50 sixty foot, but for some reason, was seeing a constant 8 degree retard (last time this happened, a few months ago, the Knock Sensors were replaced and it was fine).

The 8 degrees KR, combined with the LNC-2000 retarding timing another 10-11, well showed an actual TOTAL TIMING figure of -1 to -2 degrees which turned my nice launch into a turd run...11.65@114

Not sure what's going on with the KR. I do not believe it is seeing TRUE KNOCK, as timing is very conservative (16 degrees @ WOT, OFF NITROUS), fuel delivery and octane are good, and nitrous AFR was mid 11's most of the run...Going to start a new thread in the TUNING subforum

Glad to see your making progress. What's the whole setup on the motor and how fast have you been on just motor?
