I should not have assumed you knew the later in the evening/night the cooler air makes better times, if i had tested the needswings first, then yes the times would be much closer to each other and the first run with the needswings did run a 10.80 the same as the stock intake and then 10.79 .
to me I gained 1.5 tenth and today that equals 200 lbs weight off the car or about $1000.00 spent on a good performance part.
I do know with the needswings intake i got into the 10.7's for the first time,,
as of now I have run a 10.55 (but no time slip so i do not claim it without proof)
