I've never run nitrous, but am thinking about maybe just a little wiff may not hurt anything, right? I've read that dual plane manifolds and nitrous don't play well together and is a quick way to kill an engine because of the uneven fuel distribution as compared to a single plane(input welcome here).
Anyway, I'm already running the WFO drop base shaker air cleaner and have NO room for a plate... If there's a way to do it on a 78 t/a with shaker, q-jet, RPM manifold, safely, I'm all ears.

It just happens I have an old torkerII I bought back in the 80's on the shelf, all I have to do is port match it. So then i'm aware that switching to a torkerII mandates switching from my Q-jet to a Holley. The torkerII/Holley combo should leave room for a spacer/plate, right?

I've read alot about tuning a Holley and am confident that with my wideband I can get it in decent shape. Sounds like fun, really, if I had the right carb to start with. Can someone recommend a good Holley for an application like this? See sig below, street/strip, mostly street. I'm thinking 850 DP. I could live without a choke if I had to. I guess. There's a lot of Holley models out there, not to mention the off brands, not sure if I need the extra fancy aluminum HP, etc etc. Basic, functional, tunable, don't care what it looks like, reliable, affordable kind of deal. Thanks!

You can add port injectors into each runner right before the head.

NOS is fun and my pontiac responed well to a plate system. There is a nos set up that fastens to your air cleaner stud and is mounted inside the air cleaner if you have the room. You can also plumb it to enter the underside of the intake. I would run a hp950 holley. Here is a vid of my car on the bottle. I hit the button 10 feet out of the hole and through the qtr mile. My car back then( 1999) was street driven 75 miles to the track ran 11,40 @ 116 on the motor then on this pass ran 10.18 @ 130 spinning bad out of the hole.

like a fogger? anyone done this with a q-jet and rpm manifold? Does this even help a fuel distribution problem?

Sounds dry, I'm thinking at least run a wet system

I use a plate with a Q Jet and a Ram Air IV intake, it works fine.

thx FTA. RAIV manifold is tempting.

Intake depends on the amount of jet you plan on running. Nothing wrong with a dual plane with a plate at lower nitrous HP levels.

I just did a whole bunch of research on carburetors and, for the money, Quick Fuel is the way to go if you want a square bore. Do some research on this.

People have a tendency to get intimidated by things like air bleeds and power valve channel restrictions, but they are very easy to play with and you can use a wideband to tell how they change your fuel curve. I think every QF available has adjustable air bleeds and PVCR's and IFR's on the primary side, even the cheap Slayer deals.

I run Nitrous Works plate system. All of my suggestions are wet systems that friends of mine run. I would never run a dry system, seen too many bad things happen. Quick Fuel has great carbs and I would not hesitate to run one.

I ran a 400 with an RPM and a NOS Cheater plate system, the bars spray out to the sides. Same with the NX systems (perimeter), think those are a little better, like the Hitman setup. And since it's wet, you don't need to do much to the carb, whatever runs good for the street will work for a wet plate. I ran a 780 VS 3310 on that setup.

Auto or manual? Same would apply with or without a plate system, would say a VS for auto, DP for manual. If it's a 400, standard stroke, not sure you need to go too big, 750/770 VS or 750/800 DP. Get it running right on carb alone and then add spray. Can even leave the choke on there, electric would be fine.

Hopefully you know your exact ring gaps? And your fuel system is up to par?

Some choose to run a 1 gal aux tank on the core support with it's own pump and regulator for the fuel sol, allows for fine tuning as well as ensuring flow. Can even put race gas in it for that extra comfort. They make a number of shapes too.

Are you basically saying to tune rich enough for the leanest cyl, and dual plane and q-jet is ok?

Thanks for the info

[jonmachota78]

hwystr thx for the insight!

now I'm more confused. Here's what I think I'm getting:

I can run a plate with a q-jet + rpm manifold as long as it's just a sniff and jetted right (read rich?) This sounds great! except I still have this shaker on my back.... I don't have room for a plate.

Or could I get sneeky and stik a couple spray bars in my manifold (keep shaker) anyone done this?

OR: Port the TII, and get a QuickFuel carb$$. (keep shaker)?

[HWYSTR455]

You don't need to fatten or adjust the carb at all, it's all done with N2O/Fuel jets. The manufacturer's jetting table is on the fat side to begin with, experienced sprayers usually lean those out by going to a leaner fuel jet, or playing with fuel pressures on the fuel sol. Another reason having a dedicated fuel system is beneficial.

Distribution is the issue with spray bars installed directly into the manifold, that's why usually you see only small kits offered that way.

If you wanted, you could mill the intake to squeeze a plate on the RPM, but not sure how much material there is on an RPM before you get into the runners. If you were serious about running the RPM, as previously mentioned, plumb it with injectors. That too is a little tricky, because angle and spacing all effect distribution, so you kinda run into the same problem. Most send them out, and for the cost, would be easier to go to a different intake and a plate.

Like I was eluding to about the ring gaps, that is the limiting factor of how much N2O you can ran, and will help target the level of effort you're looking at.
