need alky help
We are running alky in a 548 ci BBC using a carb. Yesterday we made 1 time trial as we had problems on first time trial. On 2nd time trial around 3pm in high 80 degree weather car ran 8.92 in the 1/4. We went up for first round around 7. Car had exact same 60' but slowed up to 8.96. Does anyone know what would have made the car slow up as temps started to drop? Please only serious comments.
