AM I being greedy? First off let me say that I am happy with my times and all the work done on my car by Robert at Advanced Dyno.
Here comes the rant...
Before current mods, I was running 13.2 @ 103 consistantly with a 1.9 60'. So I just got a ADS4 cam, 3000 fuddle stall and a 75 shot put on my car. Dyno #'s are in my sig. Went to the track on Wednesday and here are the results.
With no juice:
Rt: .061
60': 2.03
330':5.744
1/8: 8.584
MPH: 86.48
1000: 11.01
1/4: 13.06
MPH: 110.5
With a 75 shot
Rt: .022
60' 1.672
330' 4.972
1/8 7.768
MPH 85.15
1000 10.20
1/4 12.20
MPH 108
Now I was expecting more with the cam and stall, I was happy with the MPH and can explain the ET by my 60'. Maybe if I had a better launch it would have been lower. I was hoping to get into the 11's with the 75 shot, but it looks like I pretty much maxed out. Should I be happy with that or should I expect more. Or should I just stop whining about it.

If you were spinning on your all motor run I guess that could have inflated your mph a little bit but I would still expect your nitrous run to have a higher MPH.
110mph on motor
108mph with a 75hp shot
Something looks wrong. Most of the gained ET probably came from the 1.6 second 60 foot on that pass.

i think all of the mph numbers are painfully low. my lid/flowmaster 99 ws6 traps more than either of those number sets. i would look at the tune. what size cam? this is with an ls2 gto...yeah, those numbers are real low. that thing should trap more with just headers than you are now.
fwiw i had a bolt-on 00 z28 that trapped 110 on motor with a 4k stall, weighed 3600lbs. racing @ 2500'+ da.
it looks like when spraying n2o you are just spraying fuel? is it a wet shot? the mph should not drop on the bottle. it appears the difference in timeslips is just how much traction you got, as the mph numbers are almost the same.
