2009 Mustang 4.0 vs. 2006 Sentra se-r spec v

so the other day me and my friend had a little argument about whose car is faster. He has had a truck since 16 and finally got a somewhat performance car. The interweb said that the spec v runs the 1/4 in 15.2 while the mustang is pretty much right there with it. His is stock my mustang has CAI and 93 tune. I finally got him to agree to a race but he didnt want to do from a dig, he wanted a rolling race so we went from 40. Which for stock differential 4.0's is a pretty good place to start. So we took off and all through second until about 5500 rpms we were nose and nose (he took off a little early so i did technically gain a little ground on him) but for the rest of second gear i pulled on him, hit 60 mph shift to third. When i shifted i had MASSIVE driver error because i had changed the height of my seat that day and wasnt used to it. Took about a full second to shift to third. However, when i connected, it was just walking away from him. We ended up hitting about 95 with him about 5 car lengths behind me. We raced again to try to correct my driver error, same error happened, same results. Both cars are man trans (mustang 5 gear, sentra 6 gears). anyways i just wanted to share my story with you guys. i'm hoping to have a video up very soon, i'll probably post it in this thread. HAVE A GOOD DAY!!! :bigthumbsup
