Engine Anyone (still) running a single fogger nozzle or TB plate nitrous system?

Thank you.., I figured we’re few and far between doing what I’m doing.. this isn’t 1995 lol.. speaking of which, which is preferable between a TB plate and single fogger nozzle setup..... you guys like the nozzle mounted in intake tube before throttle body or in intake after TB?

I did that backwards...There’s no part number stamped on plate anywhere but I’m 99% sure it’s part number 13005 as that’s the only plate from TNW “The Nitrous Works” (back then, I think no longer same name..?)
I have found 3 charts for part #13005 but seem like way too much spread, looks like would be lean and I’m afraid to go way lean lol

i havent ran nitrous on a mustang yet but i have ran it on a camaro and a civic. i had the same thing happen alot of the time it could be due to your jetting. are you sure its correct?

mayke sure you have a chart for your plate or nozzle. i melted alot of plugs in my civic thinking i had the right jets but i didnt notice i was using a shark nozzle and not a pirhana nozzle. changed them and it was smooth as butter

Is that what you have in there now or no?

I had a 50n 28f and had the “bucking” problem, so stepped down to 44n and 22f and it got better but there’s still a problem... I’d like to hear from someone successfully using this same plate but that guy is hard to find lol

That’s probably not bad man I know people that will spray a dry 75 shot

With no extra fuel from injectors either?? Ive never heard anything about that but I’ve had people tell me to not retard timing at all until 75-100 worth but I’m too scared to try that

I check solenoids to make sure they’re coming on frequently, it’s a 50n jet so should be 112ish on hp. It almost feels like an ignition issue, would too much timing retarded cause an issue such as that??
I realize I’m not using the jets on chart(s) but again they seem so lean compared to an online calculator... also as I mentioned already the 50n 28f starting point was recommended by guy who owns a speed shop (parts, nitrous etc) who’s also a mustang drag racer, owned store for 30 years and said he sold a lot of those plates back in the day and still suggested the yet again aforementioned 19-23 “split”... didn’t mention the chart and I didn’t have copy with me, store phone ringing non stop so here I am lol.. I plan to confer with him more when I get bottle topped off..
Thanks again guys... I’m hoping someone is/was using the same plate.. it has the same number of holes in bars as described in directions I found online but I cannot tell oriface size

i would retard the timing and set the plate up just as they say. idk what size you are spraying but if its not bigger than a 75 its not a "big" deal.

if that doesnt work you may look into just doing a nozzle system from NX or something so you know the jetting is right.

also make sure you solenoids are working correctly. make sure they click on and off. sometime people will wire them all up and only one solenoid will be working. specially if its an old set up

Do you think I should retard more than 5* or 3* with 44n 22f which is about 87hp according to calculator which actually calls for 25f and it did run better than larger combination.. so maybe it is THAT rich..? I’ll try retarding more timing but am afraid to retard more... no one here is recommending that.. im also afraid to lean it out too much either so I guess I need to face my fear(s)

Wish I could help,my carb tunes 6.5 ffp (flowing fuel pressure) are pretty much 9-10 jet spread.
Current tune is 1st kit .049n-.039f pulling 3*
2nd kit .49n-.040f pulling another 3* (24* total on both kits,about 185hp) BP is off at 1025 on at 975
92 pump in the tank,C16 in the stand alone. AFR's are low 12's. NGK R5671A-9

Guy also told me on carbs it’s usually a 8-10 spread or something like that so must be close to correct on EFI, I trust he knows what he’s talking about anyway.. you should be at same “HP” level as EFI with same jet right?
About 109 with 49n on 1st??
Thanks!

Now that I read better you’re saying about 185 worth with both kits on? That would be a little lower per hit than I figured... seems N jet would dictate “hit” be the same whether FI or Carb so long as fuel is at same ratio to nitrous, am I thinking about it wrong? Probably am.
Why are you running a fuel jet one size smaller on 2nd kit? Is there a lot of difference in just moving one size for F on carb because such lower fuel pressure?
-9 is a really cold plug right? I’m starting with a -7 but don’t plan to go bigger than a .054n which is 130ish I believe..
Thanks again guys!!

Rereading your first post that sounds like detonation (bad)
The jet spread is determined by fuel pressure. If foxbody is supposed to have X pressure (say 40) but you only have 25,
your nitrous tune is going to be very lean. And if you have 60,your tune will be rich. Do you know what your fuel pressure is ?
Are you sure the fuel enrichment is working ? And said enrichment is getting through the plate into the intake ?

Yes I agree with all the above.. my fuel pressure is set at 43psi (adj regulator and gauge under hood) I have checked that plate is cleared... well I did upon installation.. I can definitely tell fuel is getting to plate and I have plenty enough flowing to it I’m sure .. also I did not mean to describe problem as detonation.. I’m 99% sure it’s too rich if anything.. it’s “stumbling” feels almost like bad plug wire(s)
