NOS and COPS, suggestions

[Art5]

HI, all. I have cops, one 25 shot NOS kit, one 100 shot wet kit , 6 jets and extra predrilled intake manifold. I would like to use it all soon.
I have read a lot of threads about NOS and cops and all that, but can't figure out if I'm missing anything out.
As far as I know I have about 50-60K on my engine,LSD tranny, larger than stock fuel pump and bigger MAF. NO chip or tweecer though.
I was thinking to set up COPS and use E3 plugs, but don't know if I can use them with nitrous.Do I have to upgrade injectors and FPR? Would I have to make a chip for it or standalone computer would be better or nothing?
Thank you in advance.

You dont need a FPR unless you have a larger then 190 fuel pump. What MAF do you have? If it is a Mark 8 you need a LPM or Tweecer.

I would not run E3 plugs you need to run copper with nitrous.

I don't know for sure what kind of maf it is, but I got it from my 91+ when I had it. I think it is smaller than 80mm, but I have that one too, but can't install it without a chip.
WOuld I need to upgrade injectors though for wet kit?

I'd run copper 3923 plugs.
What size N2o shot do you plan on running?

 

[Art5]

I have 25 dry and 100 wet. I'd like to run both but occasionally at the same time. 25 shot for second and then 100 all the way after.
I really want to put cops on, because I think my wires are not as good as they used to be, because last night i raced SUpra turbo and kinda lost, then found out he had a bunch of mods, but still, felt like I was loosing power somewhere.

Search button dude , there is 100 threads with all this info in them .

You should stop trying to overdue everything first imo. Get the COP set up complete and running on the vehicle then go to your n2o . Set up the wet kit correctly with a 155lph walbro , and some cheap copper autolite 3923's gapped around .032-.035.

Do some research and identify the Maf before just throwing it on your car , it could require tuning to run correctly .

You don't have to upgrade injectors , a wet n2o set up provides it's own fuel. It does not use the fuel injectors to add fuel .

Again read up on all this before trying to install or your going to nuke your motor . Good luck .

I don't understand doing the COP conversion other than eliminating the need for plug wires. Sure, you will get a more direct and even spark with a COP setup but it's actually a lower output than the factory coil pack. There is nothing wrong with the factory ignition system. The only thing I would upgrade would be to go to a nice wire set. I would never use a multi-point spark plug in any vehicle. They all suck ballskis in my opinion. I would recommend using copper plugs a heat range colder, maybe 2 heat ranges colder depending apon how large a shot you run. If you're after longevity you can run a fine wire double platinum plug in a colder heat range.

Why are you using two seperate nitrous kits (wet and dry)? I would recommend using a 2-stage wet setup if you are worried about traction. This will also create the need further modify your intake. Honestly, a lowly 75 shot renders 1st gear worthless, and depending on tire, the first part of second as well. There's just not much you can do about this. Do you know what size pump you have? The stock fuel system will handle a 75 shot no problem (100 shot is on the ragged edge but I got away with it). A larger pump should have you set for a safe 100 shot. Any larger and I would recommend the FPR kit from SHOnut and a wideband O2 so you can dial in the fuel. With an adjustable FPR you don't necessarily need a tuning device as you can tune the fuel with the FPR (unless you are using an MAF that needs to be tuned). Of course, the bigger you go, the more supporting mods you will need. If you go 150 or larger it would be a good idea to be able to dial back some timing.

I believe I have 155lph pump. I have a very small dry kit, that I want to use sometimes, to play around with. And wet shot for racing nights.

My direct port intake manifold is not on the car at the moment,but before I had wet kit on my other car that I bought with this whole N2O setup, but it worked with only one jet through air intake. After about 5000-5500 rpm car would just act like this was it for any power in it. Tach wouldn't even go any futher. That setup was using fuel from fuel rail.

A non-direct port wet kit on and SHO = . So what is your goal? Using one kit sometimes and the other kit at other times? Or using them in conjunction with each other?

I know that was a bad idea, luckily nothing bad happened, but I only used it twice back then.
I had dry shot on my red SHO and used it few times mostly to get through second gear to 3rd. But that 100 shot I would like to use in 3rd and all the way up, mostly for high speed runs or when I race from a roll. It is getting harder to race against boosted cars and I can't spend on a turbo right now.

With the COPs you can run a much larger gap than .030-.035, even with nitrous.

I read about that , but I can't run E3 plugs though, right? What about running cooler plugs , how does it work with bigger gap?

Heres what your missing. There is no such thing as a 'small' dry nitrous kit. A nitrous kit is a nitrous kit., the jets are what makes the size of the shot. Sell the wet kit, and buy the 100 shot jets. Forget about COP, it does not give you any horsepower.

I know COPS don't give me power, I didn't say i'm going to change COPS for more power. I think that I keep having issues with this car and its wires, plus I would like to have something more updated there. As for dry or wet, why do you think I better off with dry? By the way, my small dry kit is 25 shot with a very small bottle, that's why I call it small.

Heres a thread where you already asked alot of this .
http://www.shoforum.com/showthread.php?t=113413&highlight=direct+port+n2o

I dont understand why you want to try and use both n2o set ups ? use one or the other get the car tuned safely for that and have fun with it .

Indeed, using a wet kit and dry kit at the same time would be pointless. Using your direct port setup would have the extra cool points. It sounds like you should stick with simplicity until you get the hang of it. Get some 75 shot jets for that dry kit and call it a day.

I would not run E3's with nitrous. Autolight 3923 is one step cooler than stock plugs for this car and are cheap. We used these plugs on supercharged cars back in the day and work well with nitrous as well.

I can do nothing with that small dry kit, because I don't think they even have jets for that bigger than 50 shot. It's one of those kits that uses thin lines like plastic.
I read all of these threads before, but one thing I don't understand is wethere i need FPR or not for a 100 shot and how would it be tuned, since this is not a turbo , doesn't work all the time.

You do not need an FPR for 100 shot. Because you have the 155 lph pump you should be OK with that. You do not need to tune the car because the wet kit is providing the additional fuel needed when the nitrous is engaged. A proper dry kit compensates using vacuum to the FPR to add more fuel. It's never a bad idea to have a wideband O2 just to verify you aren't going lean but, a 100 shot and lower is no big deal. I've never heard of a simple dry kit as you explained... please tell me it isn;t some cheapo ebay crap someone dreamed up with some compressed air and duct tape.

ok...What brand and model is this "small" dry nitrous kit you have... As far as E3 plugs DO NOT USE THEM....I used to sell them, out of the 50 sets i sold, about 40 came back within 3-6 months.
