lol - i barely use my cell phone, which is an iphone (albeit a 3 and not even a 3S). i am likely one of the last ones on the planet who thinks that a cell phone is just for emergencies, and is the rudest thing to use in public. when and why did we become so dependent on instant access? is that really a good thing?
i don't want or need to be so accessible, and do not want to be interrupted with a phone call. i don't text, and feel that texting is the downfall of the written word. people can send me an email, or leave me a voicemail. i'll get back to them when i can devote my full attention to them, which is the only decent and civilized thing to do. nothing annoys me more than being in a meeting with somebody, who then gets a text or phone call, and has to stop what we are doing to deal with it. i have gotten up and left when that happens. i will ALWAYS immediately eliminate anybody who does that from any bidding process when i am looking to hire somebody. i blew 2 of them out the door last week.
remember when we had rotary dial phones, no answering machines, no call waiting, and no email? people actually talked to one another face to face. no flame wars. no miscommunication. no internet bullies. what a concept.
back on topic now.
there are indeed a number of things that can easily explain why dan's car might be faster than another car. the least of which is the balance of the engine and the setting of the cams. the cams alone can make as much as a 20hp difference. the state of balance can easily mean 1/4 second off your 0-60 times. the same goes for intake casting variance, valve condition, lifter condition, etcetera. all of these things add up.
engines are built to within certain tolerances. these tolerances leave a lot of room for variance between engines. if you got one that was perfectly balanced, and the cams were set to one direction, you could have an engine that made more power up top. if the cams were set to the other direction, it would be torquier down low.
this is exactly why engine builders and tuners get paid so much. they know how to take advantage of these things, and get the most out of an engine, without changing it from stock. this allows them to get the most power without breaking any rules. it really is a large difference.
basically there is enough variance between engines to easily equal anything you could bolt onto it to make more power. so, for example you could even have a car with an engine at the lower end of the scale, with all the bolt-ons, still get outrun by a car with an engine with no bolt-ons but at the upper end of the scale. if you were lucky enough to get one at the upper end of the scale, and then bolt things on, you would really have a nice setup.
this is likely where dan is. lucky guy.
