I have a 2005 RC SRT-10 with these mods, Bassani headers, Mid-pipes, Maganflow cat back, B&M shifter, and K&N cold air intake. Made three passes, the temp was 59 Degrees, Humidity was 67. First pass was a 13.209 at 110.18 1/4 mile. Best pass was a 13.104 at 111.12 1/4 mile. My 60 foot time sucked 2.3 and a 2.4 , I need Slick or drag radials. I just want to share with everyone, I will be getting the Computer this week and I will see if that makes a difference
