dramatically being the key word, you just admitted yourself that those power adders hurt a stock engine over time. Sounds like your a hypocrite...
power adders make a bigger explosion (combustion) and add more boost to the cylinders, therefore put more stress on the engine.
The bottom line is, these engines weren't built for boost. Even small amounts of boost are going to affect the engine somehow.
Don't put words into my mouth! I admitted nothing of the sort and no I'm not a hypocrite. When I stated that a power adder wasn't going to going to shorten engine life dramatically, I also made reference to comparably built N/A combinations as well.
Any time you modify an engine beyond it's stock parameters for the purposes of measurably increasing horsepower, you increase the risk of shortening an engines life span. Sure, maybe a N/A engine making 30-40rwhp over it's stock configuration with simple bolt-on's may not affect engine reliability in the slightest...as a matter of fact, it may even heighten an engines efficiency if done within reasonable parameters, but then again even the most simple power adders are good for a total 325-350rwhp, so to compare a bolt on N/A 4.6 making 265-270rwhp and even the most basic blown engine seeing 330-350+ isn't exactly a fair comparison, is it? So feel free to build a N/A engine to similar power levels....then what are you left with? You're fooling yourself if you don't think that pushing a N/A 4.6L to these output parameters isn't stressing it's mechanical components to any lesser extent than that of a basic power adder...even more so at the high end of the horsepower spectrum.
Is it going to burn your engine down in the first year? If built and tuned right, absolutely not! There's no reason that the owner of either combination can't enjoy thousands of trouble free miles with proper maintenance. Will the engine last as long as a bone stock 4.6L.....not likely, but the means to that end is going to be related directly in retrospect to an owners driving style and how they're treating the new found power under their right foot. Will a 450rwhp+ blower car with stock internal components last as long as a 300rwhp N/A combination? No definitive proof either way, but the answer is not likely. But in the same respect, I'd put more faith into a 350-400rwhp F/I engine than a N/A unit with the same output level running stock internal components. Had we 4.6L modular owners been given more displacement to work with from the factory, higher horsepower figures would have come with much less effort and without the need to "ride the reliability line" so to speak. But we've got to work with what we were given.
I'll clue you into another fact that you may or may not be aware of. Excessive cylinder pressure isn't the only killer of an engine! Excessive RPM is going to do more damage over the long run that a little bit of boost. Staying with the numbers, your average F/I car is seeing anywhere from 350-400rwhp. Excessive RPM isn't necessary with this set up, since the horsepower being made, is done so within the same RPM limitations as it was stock. There just happens to be more of it between both ends of the power curve. This same reasoning unfortunately, doesn't hold true for a N/A engine making the same sort of power. In this case, without displacement, you need RPM. High horsepower N/A combinations don't make stump pulling torque at off idle or even moderate RPM, like a F/I engine does. The majority of that power, is all made at the top end of that tach, where unfortunately for the owner, reliability starts to take a back seat to power production.
….that’s just the way it is.

So many users abuse the use of their power adders, and blow their engines to hell. Why take that gamble? Maybe you have sh1t loads of money/time. Those two things I do not have. My standing stays the same.
Just for kicks....run the cost figures in your head as to what it will take to make 330rwhp N/A in comparison to what it would cost to do it with a power adder. I'll give you a heads up, that between N/A, nitrous, or a blower, you're going to spend the most money doing it with all motor. If spending the least amount of money to make the most power is your goal, then my friend you're going about it the wrong way.
