Off the top of my head the secondary jets for the last/best pass were 95 and 90 for the primary.
I think the car is about 2550 lbs with me in it and low fuel. I don't launch the car, but start a bit over idle, so time is about .4 slower that potential. Use MPH for HP calculator in this link.

The pass should come out about 430 to wheels uncorrected. Correct that to sea level and it's around 463. I think it would put down about the same on the load bearing Dynodynamics were I usually go. I'd like to put the car on a Dynojet for some bragging numbers that are a little higher.
If you want to sea level correct here's a link.

It comes out about 2200 ft DA, but I called it 2100 DA to be safe.
