Default I put in the 75 shot today.....

First I ran n/a and ran 12.82@ 111.... Not my best but, I then run with the 75 shot hitting it at the beginning of 2nd.... I only ran a 12.32@118.4...

2 days ago I ran the 1/8 and a little past with a 200lb passenger it it ran 12.35@109.. My top speed was 112 so i Let off at 112 coasted through the 1/4 and still did good.

After I ran I checked the bottle and the pressure was at 875 when its usually at 975-1000. could this be the problem?


Also what should I have my WOT a/f set at running n/a for running nitrous? Right now its at 940's....

Also once I get that right what should the WOT a/f be using nitrous?

depends on the 60 foot what was it? Why didn't you finish the 1/4? Bottle pressure does have a big affect on your et.

I only had room to run the 1/8. 60' was 2.05 the same on both. It was just kinda weird that I would have been in the 11's easy one time and low 12s the other with same 60's and pretty much the same 1/8's.

Yeah I was using a g-timer so maybe one of the runs were a fluke. But as far a consistency is usually right on. I even took it to the track and it was perfect.

From what I have read my n/a a/f ratio should 900-910 if im going to spray? Does this stay the same during a run w/ nitrous or should it go up?

i dunno if this helps.. but ive run a 75 shot with mods in top of sig and dropped about 8 tenths... when to the 150 and had a much worse 60ft in the 2.20's and ran a 7.79 1/8th spinning instead of my usual 7.45-7.50 1/8th and still picked up 1.2 seconds or so and about 15-16mph.... if ur best i see in ur sig is 12.50 on street tires, then id run me some m/t drag radials and id say u could knock down 11.75 on the 75 shot cuz ur 60ft alone should be in the 1.80s even if u have the stock stall as long as u hook and spray it about 2800-3000rpms in first gear and keep it in there thru the 1/4 mile.

Buy some tires and hit it off the line. Then you will see all the ET you are looking for!

1.8's spraying on stock converter?

I pulled 1.801's with stock converter, cat back (Slp LM) and a Cold Air induction with ET Streets...

Get some tires like Offaxis stated.. you will be amazed at what you see.

I am hoping for a second drop with my NX system.. but seeing as some people here state 1.2 second drops with a 100 shot.. makes me optimistic..

But I will tell you what.. I will leave the number guessing to the people who dont go to the track.. and i will let you know what I did at the track whenever I get over my fear of blowing this 10 bolt up.

LOL

Have a good day guys..

I have et streets and have run them......My best was 12.5 @112 but since then I have did a little tuning and the weather has been better.. Im thinking I would get low 12's n/a on them but havent tried yet....

Basically what confused me was how i was obviously going to run high 11's one day and then low 12s the other day.... Its like the nitrous was working as well....thats why i was wondering if 800 psi would hurt me by like 4 tenths are so....

Also I think i May be running to rich for nitrous but cant seem to fine anything in the search taht is specific about what i should be running.....

Is low 900's good for spray??? Should I stay out of the 890's or is that safe as well?

950 and up on bottle pressure atleast.

950-1050 is good.

As for the tune.. I dont know. I am in need of one myself. Make sure your A/F ratio is ok though bro.

Dont go and blow up your motor.

500 for a tune is better than 6000 for a new motor

Have a good day guys..
Time to man-up!
The stock 10 bolt is not that weak.
I have pulled 1.5 60fts for about 2 years now(knock-on-wood)

With the wrong convertor for spray,i went from 12.7 @107 1.7 60ft
to 11.4@119 1.54 60ft on a 150 shot
I even tried once to see what it would run the way i drive it to work,Stock tires(Now Drag Radials) 100 shot and nothing removed(always has been full weight 3636 raceweight) It pulled 11.94@115 1.7 60ft!!!! Not too shabby.



Keep your bottle pressure between 950 and 1050 and if it gets any higher,COOL it down before you spray!

Good luck!
Dave
