its not really THAT funny to be honest..:S because:
1: that riced corolla is keeping up quite well with the GTI
2: right towards the end of the video, its quite evident from the grin on that guy's face that he's just playing around with those other guys...(he couldn't get the spelling right, yea right).. to be honest, he made quite a fool out of those laughing hyenas.. LoL! (H)
P.S. when it comes to engine mods, i'm quite nill, but even I know that the engine pulley has nothing to do with a turbo...:S he's just fooling around with those guys..
