Results vary based on the combo. If you just threw a 200 on it and changed nothing else but total timing you'll pick up X amount. If in addition you installed a tighter converter and a lower numerical ring & pinion, you'll pick up X+ amount.

I ran a tight converter and a 3,73 gear with 29" tall slicks. Naturally aspirated the converter made the car a pig in the 60' (it would only flash to about 3200 rpm). Launching on a full 200 hit it would "wake up" and flash to 4300-4400 rpm, allowing it to "leave on the cam".

At 3850 lbs. race weight I got the following best 1/4 results:

11.40 @ 120 n/a
10.19 @ 131 on a 200 shot

I always ran the fuel pressure at 6-1/2 PSI to the nitrous system solenoid with it's own proprietary fuel pump and line. I always pulled 8 degrees out of the total timing. I ran the mechanical advance locked in the distributor and used the "start function" in the MSD box to pull 20 degrees out so it would start. I usually ran between 32-34 degrees locked naturally aspirated. I also tried to leave with the n2o bottle pressure at 1000 psi. The nitrous solenoid was wired with a WOT switch and was all there on launch.

And read your plugs, you may find even with a 200 shot you may have to go one range colder (maybe two) from naturally aspirated.
