oh so close......

Gotcha, I was just looking at the 10.1 @ 131 part...that is pretty much identical to what my car is running (ET and speed), and my car is very well sorted out. That is why I was saying a little more nitrous would put you over the top, or if it could handle it, a couple more degrees of timing.

I used to run nitrous all the time many years ago...fun (and safe) if applied correctly.

Depending on the ops actual tune a couple degrees less perhaps?, no point in hitting the pistons while they are still on the way up?. I only got 1.4 secs gain from an old cheater 250 shot (around 200hp .093 thou orifice N solenoid) on my 340 back in the 80's, rich tune (110N/110F) and only came back 3 degrees on 97 leaded octane, went from 108NA>122.8mph worked out to only a 130-ish hp increase according to weight/mph. More you clean the tune up today with smaller F jet the less advance, timing is what kills N motors, not lean is how I see it.
