What will be worse on a car, cams, or a supercharger (assuming both cars are tuned properly). The supercharger will have a greater effect on the engine, of course. Even if an engine has a sh1t load of N/A mods done to it, air isn't being FORCED into the engine in large increments. When boost is forced into the cylinders, it's almost like the pistons recieve a huge "jolt". They go from a normal cycling rate, to a very fast rate because of the boost, giving you more HP. But naturally aspirated engines do not recieve that large force that moves them to much faster speeds in such a short amount of time. Therefore, there is less wear on N/A engines even if the car is modded to hell with new heads, cams, exhaust, and any other N/A mod you can think of. Do want you want, but my experience with boosted cars has taught me a lot. And as far as realiability goes, N/A cars are WAY more realiable

Interesting mindset you've got......one sided, but interesting none the less.
I'm not exactly sure what point you are trying to make with regards to a "normal cycling rate" as you call it? Yes, the engine will make power more quickly moving it into (and even extending) it's power band that much faster, but you're not changing the rod/stroke ratio, so the rotating assembly isn't spinning any faster with a blower engine, than it is with a N/A engine. It is true that you're introducing and expelling a larger volume of air per complete revolutionary cycle, which is where things can get out of control in a hurry with a blower car, but as you stated yourself....both these engines are tuned properly, are they not? In which case, you're not going to see any excessive timing, or lean fuel curve rates with the blower engine like you're insisting and as a result, you're not going to have a problem. Of course every engine has it's limits, but considering there are more and more blower owners challenging and beating the odds every day, your outlook on these limits seems speculation at best.
Not all that long ago it was nearly unheard of to run more than about 6psi and 320-350rwhp on a stock 4.6L bottom end, for fear of disaster. Now a days, with improved blower efficiently, aftercooling and a wider variety of tuning parameters, your average Stang owner is running 8-10psi and most are seeing 400-450rwhp without ill effects. Don't even get me started on the newest crop of 3V engines. They've got the same internal components that the early 2V's do and I don't even think you can buy a blower kit for them that makes
less than 420rwhp.
If there's going to be a reliability issue with a car running a power adder, then 9/10 times it's going to be due to human error. Either an improperly tuned set up or constantly bagging on your ride because of the new found power under your right foot. A heavily modified N/A engine is subject to these same limitations. I don't care how much power it's making or how it's making it. If you're running with your foot in the oil pan all of the time, you're gonna shorten the life of your engine no matter what you drive. That aside....what exactly is it that you consider high maintenance about a blown car?
Having to change the blower oil once and a while?
....and what's with the

thing?
Since when did this because a Canada vs US thread? Because I'm not a citizen of the US, I don't know what I'm talking about? Many on this board might disagree with you! Or perhaps you mean to say that your comments in this thread have owned the Country itself, is that it. Or maybe you were just feeling petty because someone posted an opinion the differed from yours and attacking my geographical location on the map was the only thing you could think of on such short notice? Feel free to explain?
