Nice starting point. So with a 150 shot on top of that we will be looking at 550+ rwhp.
Definately get a pump
I would opt for an MSD ignition that has retard capabiltiy. I believe their is a harness adapter that plugs right into the stock plugs. Youll have to ask around or do more research on that one. But you can set the MSD to pull a few degrees of retard when the nitrous is spraying. I wish it were that simple on an LS1
TR6 plugs will probably hold you over although I would inspect them on a regular basis after spraying

I do believe with an MSD and using some timing retard you will be able to get away with spraying that 150 shot on 93 octane. And almost certainly if you use something like the FJO/NX controller and set it up in RPM mode. However...if it where my car and I was running at the track I would probably put in a few gallons of 100 octane unleaded. You would be amazed at the extra cushion of safety that gives in terms of detonation control.

And the only name of the game in staying safe with nitrous is detonation control

here is a pic of my dyno graph on a small 200 shot using the NX/FJO Maximizer in rpm mode. Note the smooth seperation from the NA line...especially importsnt on the TQ line. TQ is a direct measurment of cylinder pressure...so by looking at Tq we can see where detonation is more likely. It will always be more likely at peak TQ. This graph was done starting at 0% nitous at 3500 rpm and going to 100% by 6000 rpm. Youll see the graph mimics an NA car. This will keep you safe as safe can be. Compare that to a regular on/off type nitrous kit that hits at 3000 rpm. You will see TQ skyrocket stright up 200 or so ft/lbs and taper off from there. That is exactly what you DONT want. The Maximizer also can do % or nitrous by gear....all your gears. So if you want 0-10% in first 10%- 25% in second 25-75% in third and then 100% in fourth you can do that to.



I would aslo recomend checking your setup out on a dyno with wideband before playing on the street or track

 

Nice graph Al, and numbers. One additional thing I would like to make clear is the fact a engine can handle more nitrous more safely in the higher rpms. This is the greatest benifit of running progressive or multi stage, a bigger hit and a longer more linear torque curve. Al's graph is what I am aiming for with my multi stage, on a stock longblock.

Edit: If I remember correcly, the Opti spark can be somewhat problematic when running nitrous?

 

Thanks Robert

The opti is just problematic period...lol. Some get lucky and rarely have them crap out...others seem to go though one a month...lol.

 

Can't we just all get along??? Hey Jeff, are you a member of the GS registry? I'd be glad to post in here but i'm afraid of the rocks and stones that will be thrown at me.

 

Yep a member of the Registry. And as far as the rocks, you have to duck a few to get all the right answers .

 

Well I'm with ya on the spray. I am looking for a kit right now as well. We need to trade notes. I will only be running a 75-100 shot and will most likely go with the Barry Grant kit. I like the plate setup they have...makes for a nice clean N2O introduction and atomization. I'll be getting a few bells and whistles as well but not as intense as yourself. My motor is mostly stock and I plan to keep it that way....400 RWHP is enough for me.

 

db...im in Tampa as well...if you need any help just let me know.

 

The system mentioned by nitrous direct is a very good way to have a direct port setup. No removing the manifold for drilling and very easy to install. however, from looking at the setup you can see that the placement for the nozzles will affect the spray pattern of the injectors.

i have only had experiences with NOS and NX and I can tell you that NX is by far the better company of the two. i am using the NX maximizer as well and it is a very good way to control your nitrous flow.

 

I assure you the Nitrous Direct/Cold Fusion direct port was designed by engineers that took your concern into account. Fact is, there is no detrimental affect on n/a performance what so ever. NOS has the basic same set-up in thier NOSzle system which has been out longer and is a proven winner on the big stage. I will be running this system on my Z06 for the plug and play factor, which is an easier/cheaper install and everything can go back to stock when resale time comes, no butchered up manifold. Just some insight to think about.

AWESOME thanks!!
