I cut a hole in my sealed Airaid to hook up the ram air hose to it. Just ran at BSD this past Friday night. Conditions were great, very low humidity and air temps in low 60's to high 50's. Starting line had amazing grip, which cause couple passes to have wheel hop. They had a low car count, so we had open time trial for 1.5 hrs. My best run was #2 for the night, with 14 mins between first and second run. I didn't raise the hood all night, so everything had total heat soak. The car I ran against was a Nova with racing slicks. As you can see his R/T, he smoked me. I ran him down around 1/8 mile then went around him. Car seemed to pull better with the sealed Airaid/ ram air.
Nova
R/T .125 .009
60' 1.877 1.876
330 5.337 5.326
1/8 8.250 8.271
MPH 84.72 82.69
1000 10.764 10.878
1/4 12.890 13.074
MPH 105.65 101.87
The 12.89 was my best, my second best was 12.95 @ 105.77, but this run experienced bad front wheel hop, so probably would of been better. To me the car seemed to run better with very little time between runs. On on another note, took car to a picnic Saturday in the rain, when I got there I opened the hood to check the air back for water or being damp, I found nothing, which was a good thing.
