When my car was ( NA ) there was about a 3-4 tenth difference in 1/4 mile times due to temp. at the track with temps in the high 70's to low 80's the car would run 13.9's or 14.0's. the best it ever ran ( NA ) was 13.58 at 101.5 with a 1.94 60ft. The temp was 56 degrees out and the track was prepped well. So anyhow now i have a 6psi powerdyne on, had to give up my race pullies and short belt because they wouldnt work with the charger, and went to the track about 2 weeks ago. the best I ran was a 13.23 at 106.1 with a crappy 2.08 60ft. the temp was 72 degress. So my question is for everyone with a charger on their car. What kind of time difference have you experienced with your cars running them in warm weather as opposed to cool weather. Everybody I talked to said that when the temps start to get into the mid to low 60's and cooler that thats when the superchargers really perform. I guess I was just hoping to see a 12 second pass in the warm weather. Any feedback would be great.
