Wow! 19 minutes. That must be the quickest pulley kit swap. I think I got ripped off by my local mechanic. He quoted 2.5 hours and charged me $183.xx. I know that it could be done in 1/4 of that time. Well I got to enjoyed it the last few days. On SUnday, some guy in a modded integra pulled along side on an empty Interstate and raced me. He couldn't keep up so I slowed down when I hit 105mph. He gave the peace sign and we went our own ways. That was my first race. THe car pulled really stong and in no time, it hit 100+. This is the best mod for the money. YOu can actually feel the power. Most other mods such as CAI, Exhaust, etc.. don't really make enough power to really feel significant different.
