How much does the high temps and hi hum. effect the 1/4? I went drag racing today, and I hoped to get a better 1/4 time than i recieved. In the beginning of the day it was in the 90's. But later at night it cooled down to probably about 80 and i dropped .4 off the 1/4 time. I have a ls1 346 engine, and I was wondering what would be the best weather to go drag racing, thanks. <img border="0" alt="[Firebird]" title="" src="graemlins/formula.gif" />

Any more wind and they might think twice about opening the track. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />
