Pretty big lean spike on initial hit, reminds me of the NXL pulling fuel out of the rail. How is your fuel / nitrous system setup?
AFR after that looks very stable, if running a 300 shot I would fatten it up a little until 4500rpms and then slightly and slower lean it up some to where it is now or maybe 12.4 at max hp. But thats fine tuning it. Looks nice. Update the sig now man!
*Edited* went back and seen the first post. Are you bleeding the air out of the fuel side/priming the fuel?

I dont think he did when he dynoed it, I forgot to tell him about that. The lean spike was on my first nitrous run and the second run looks almost perfect so Im pretty sure thats where the lean spike came from. Overall Im very pleased with how my nitrous system is performing on the A/F ratio.

11.9 w/ 484rwhp?!?! were you on street tires??? that e.t. is HORRIBLE! i'd get some more practice in before i put the spray to it... the way you're going now you'd probably run 11.5 w/ a 200 shot.

Yeah the ET is "horrible". Guess you didnt see the little 2.0 60 out beside it.
Cars running on a stock 10 bolt and I have already twisted an axle off in the car once and Im not doing it again. Might want to know more about a situation before you make yourself look more like a moron than you already have, which would be hard. Whats this got to do with my dyno?? I posted that up to make sure A/F looked good and all. I didnt post this is the drag racing tech forum and ask why I only ran 11.9, I know why.

IMHO i would have gotten a 12 bolt or a 9" before i did all that axle twisting crap and put a tire and suspension to it... that way you can run better numbers w/ less power and not have to worry about breaking anything... but that's just my .02

Dont you think if I had the cash I would have bought a rear for the car? I didnt get offended by you at all but I can tell when someones being a dick. When the cash is available I will buy a rear end. At that point I will run some 10s and make you happy.

Maybe you are misunderstanding the way things happened.
This car was originally going to be a cam only car wth a 150 shot on it, not much track time and a daily driver. I figured most of my races would be from a roll on the street. Well I did the cam and nitrous and ran it that way for over a year with no issues until my solenoid stuck open and melted a piston. Well at that point I was going to just replace the piston but it was going to be rather expensive just to do that and I really needed forged ones anyway. The guy that was doing the work told me he would give me a really good deal on forged internals and a 383 kit since I had to build anyway. Well then he called me back and said for $400 more he could build a 408 so thats the direction I went. I didnt have the money to do it but I borrowed some and pulled some out of savings to do it. I still dont have the money for a rear end though.
