That's what I was thinking, climbing slowly so only another hp or two at 6500, so, 606hp, maybe holding to 6700 but I don't see any jumps in power above 6500rpm.

Its done @ 6400 RPM, but it will hang on to 7000 RPM.

Thanks so much for the simulation! And I knew this was going to be the results when I couldn't get into the 6.20s, I saw the 6.31 on the board from the driver seat on the first pass and I knew I was in trouble, then another 6.31 on the second pass, we then dry iced the intake as it was heat soaked, but ice got mixed in with the dry ice, and of course the water came, we tried to pick out the ice and run it, after the burnout they shut us down, it was heart breaking, we went back to the pits and cleaned up the mess, by this time there was no more dry ice, as we got the intake cleaned up the heat came right back into the intake, a horrible mistake was made that day and it cost me the 9s, we made a final pass, of course the power adder freaks were out and in the lane next to me, I went into the beam first and waited for the power adder, he finally lit both bulbs, I rolled in, but to slow for the starter, he red lit me, I ran through no time due to the red light, But we had the draggy in the car and it read 6.31.........................

By this time I've had enough, 200 mile drive home, to late to make the road house, screwed again in the TX conditions, but the best part of this whole thing is your simulation, thanks so much!
Thanks to Larry Meaux for the simulations!

Three 6.31's....I know you want more but I'd be happy to bracket race that!! (of course, then my bad lights are more obvious when I have a bad package) LOL
