Any typical spec sheet says that there is a 20 or so pound difference between the coupe's and sedan's...97-03's tip the scales around 3600-3700 IIRC.
Like most people say. Especially since you had 2 buddies, 2 tires and just a intake. I highly doubt he wasn't WOT...or like mentioned too...he needed a driver mod BAD.
If it is a '03-'05...they were rated at 287hp and 274 ft. lbs...'06 to '09 are 306hp and 268 ft. lbs...so they gained like 20 horse and dropped 6 tq. meh whatever nissan lol
I say if you ran it cool...but he wasn't on it I guarantee it. Try again with no buddies and tires![]()
OH...and to whoever said 15.5 in the 1/4...driver mod. A buddy of mine has a '04 (the slow ones) and he ran 14 flats all day...
