I don't want to come off to rude of anything, but I get kick out of watching you guys thinking that certain bolt on's mean certain times. The one thing that everyone seems to forget when it comes to power and 1/4 mile times is ALTITUDE!! (more air = more power, less air = less power) It makes a HUGE difference!!! 13.50 in California is a 14.50-14.70 in Denver. Every 5000 ft you go up mean about around .75 to 1 full second slower in the 1/4 mile.
