Dogbanger, huh? Anyone ever tell you that sinking to personal attacks is a sure sign of losing an arguement? BTW…I noticed you are again doing some backpedaling and denying comparing power outputs of N/A cars to boosted cars….does this in any way sound familiar? You’re the one who made the comparison right off the bat between what would need to be a moderate to heavily modified N/A engine and an entry level blower car, not I….or are you still under the impression that the average 4.6 owner can just add a couple of Mickey Mouse bolt ons and run with a blower car? If you’re going to spread around the crap at least be man enough later on to stick around a clean it up! I never once implied that blower cars were indestructible, so feel free to shelve the exaggerations any time. It’s a reality, just as 01Steeda stated, that increased cylinder pressure from a power adder will add a measurable amount of stress to the bottom end and more often than not, it’s one of the top ring lands that bites it. What I’m saying is, is that running a moderate amount of airflow, with conservative tuning parameters is still going to prove more than acceptable for these engines without worry of failure. I’d like to say that this is only a theory, but this statement has been proven many times over in the recent past. Thousands upon thousands of Power Adder cars running the streets, working within reasonable levels of power are living long and healthy lives and continue to turn more than impressive times and horsepower numbers as a result. How impressive? Impressive enough to run mid/low-12 and put down numbers in the mid-300rwhp that will effortlessly meet and usually beat even the most aggressively built N/A combination running those same weak stock internals. Weak stock internals that are just as likely to damage the bottom end with RPM in an aggressively modified N/A car as a Power Adder car is with cylinder pressure. You want to talk about engine wear??? Lets talk about how a N/A engine that’s going to be built with enough power to run with a blower car (again….as stated in your original post) is going to sacrifice huge amounts of off idle and low-end torque in the process. How does one deal with the loss of torque….by adding gear and by running the engine at higher RPM levels to keep it closer to it’s power band. Sounds like a recipe for engine wear to me? BTW….most power adder cars are capable of high-11/low-12 second times, not high-12’s. If you’re seeing many boosted or sprayed Mustang running high-12’s, its either because the owner needs a lot more practice harnessing the power and putting it to the ground, or is running the most basic of power adder kits. In which case, you're in for a rude awakening when you start spouting off your "opinions" to some guy that's actually put a few dollars into his ride or knows how to drive his car. ......and if it seems like I write miniature novels with each of my replies, it’s only because I feel as though it’s warranted to clear up all of the misconstrued information from your previous posts!
