i've got stage2 w/toys 22psi clamped at 17psi i've also got just about every bolton plus a ptp economy exhaust manifold.my nitrous kit is NX shark nozzle (35n 22f) w/iceman pure- flo nitrous soleniod and big fuel solenoid from the direct port fogger i had on my stang.i can monitor whats going on with dual aeroforce gauges and a aem wideband.with the thing being clamped my timing is about 32 degrees and my afrs are 11.8 falling to 11.5 (out of HOM )at my shift piont and i don't want to mess with the tune to run the sauce, so my question is should i spray and hope thats not to much timing or ,don't spray it is to much?

im no expert but i think its not a good thing to spray when clamped.. Reason being when you clamp it down it lowers the boost reading the ecu sees therefore ups timing which is bad for using nitrous correct??

Thats why i'm asking because i don't know how much timing you can get away with running on these cars and still use the nitrous.My computer is only seeing 17 psi and before the map clamp the timing was around 27 degrees and the nitrous didn't seem to mind now its 32 degrees and i don't want to find out the hard way that it is to much.I was wondering if anybody had logged their timing and could give me some insite.I've broken my fair share of shit with nitrous (two production Ford blocks just as an example)and don't want to do it with this car.
well i know good timing on these cars is 30-33 but thats perfect condtions and no knock!! But you do not need to run that high using nitrous i say mid 20's should be about right while keeping a check on the afr's also. this is where a good standalone would come in you could pull your timing back enough to make for a safe shot manually!

I kinda agree.. Guys, don't get me wrong, His car runs pretty damn quick for a Stg.2. He use to have an inline switch for the clamp,.. you know,.. to disable it. But, a minor rewire issue left the switch on the work bench.
Myself, I would just put the damn switch back in, or.. back off the clamp a bit.. and tune it for the sauce. I personally think thats your only option, if your hellbent on using it. (clamp'd on the sauce)
Damn dude, HOM, or N20.. I know your quicker and faster, I think pump gas runs might be "close" I figure you'll still get me.. but, I don't think your gonna RUN away from me.
If you run C12 you can run the nitrous and not worry about the timing. Do you have a hexalogger or other way of watching Knock? Do you have the capability of setting up a trigger to turn the nitrous off if you see to much knock?
On pump gas you may want to back the timing up or run a very low shot, but if you use race gas you shouldnt have a problem. You could also probably get away with the nitrous if you kept your a/f ratios in the 10.5 to 11.0 range but it would just be easier to use race gas. As long as you are not seeing knock and your a/f ratios are fine than you dont need to worry about the timing. The only true way to find out is to run it and datalog the run, logging the a/f ratios, timing, knock, etc. Even though you have a map clamp the computer should still pull the timing very fast if it starts to see alot of knock. If you log your timing and you see that all of a sudden the timing is being pulled than just use better gas or back the timing up. Alot of people have and still use nitrous with a map clamp and as to date I have not heard of any one damaging there engine due to this. Every blown engine I have seen has been from mistakes made and not the use of tuning aids. I am also assuming you were not talking about using more than a 75 shot. Higher than that and you will have to back the timing up.
how big a shot? you're supposed to pull 2 degrees for every 50 shot. also, do the runs on a dyno with a scantool, to watch for knock. if you can clamp it at 18 psi so your timing is 29 degrees or so, then you should be fine with a 50 shot.

its just a small shot 35hp until i get it figured out.i can monitor knock on my scan gauges so thats not a problem i was just trying to get an idea so thanks everybody

You pull timing or can add higher octane fuel. You dont have to do both. When running the same octane fuel than it is recomended that you back your timing up, but adding higher octane fuel will prevent knock or, what it really is, predetination. I know you know this Wannasupra but believe it or not someone reading this doesnt. If you are going to try running the same fuel back your timing up. With a 35 shot you will probably be fine no matter what, but you will be disappointed with the power and jump up pretty fast but since you have used nitrous before I know you know this.

Follow the guru! On a real note if you pull the boost back and clamp less you can get 350+hp and 400+ lb-ft of torque out of a 75 shot. I did it with minimal mods the only mistake I made was my jet placement(froze my AIT sensor).

Yes the SRT4 in stock trim loves the nitrous. You really dont have to do much of anything to get an 11 second run out of an SRT4 running a 75 shot. Slicks, Free flowing exaust, and thats about it. You will be pushing it, but it can be done.
