My car normally runs 8.70's at 81.xx in the 1/8th. Lately it is running 9.1's at 78.2xx. Does heat and humitidy have that kind of an effect on these cars? I ran the time in my sig in 70 deg. weather I don't remember the humitidy though. Last night it was probably mid 80's and a storm was coming. Could something be wrong with my car or is it the weather? I had the car dyno'ed at FFW in Commerce and it made 226 hp and 263 torq. I thought this was kinda lowconsidering my mph. It was also very hot there like mid 90's. Any ideas would be greatly appreciated.
