I can get that done on the SAME dyno, the same day. Real simple. Get to the weather station, isolate it with a vaporizer. Like magic it make 7-10% more corrected power.
It takes a lot less than 530hp to push a 3200# A body to 114mph. 530 at 3200 should be north of 120 and closer to 125.
Go watch reruns of Pass Time if you want to see inflated hp numbers and crappy MPH. :)
