One of my favorites, welcome

At 115, data shows that you are at 8.2 pounds per horsepower, and have the potential to go 11.4. So a bit of sorting even with lousy 60 fts,should get you 11s easy enough.
But, the 8.2 seems to indicate your 451rwhp engine is a tad lazy/off-tune,the car is quite heavy,or she's trapping too far out of her powerband.

At 451RWHP, crank power should be up around 510. And the Demon raceweight should be around 3500 so 3500/510= 6.87 pounds per hp, and if close, that should be about 124mph with potential to go 10.8
So there you have some data for comparison.
