[QUOTE="blown03mach1, post: 10296302, member: 54705"] As mentioned, best thing you can do is find a great tuner! These motors are not forged (just the crank in the 5sp only is) so high hp will lead to certain rod/piston failure. Also, 450 is the accepted highest level on the stock motor, but I have read of motor breaking in the sub 410 area. You will also need to realize that just because your motor may make 445 on the dyno during tuning, that does not give you a green card to beat the holy crap out of it. Like I said, this motor is not forged. FWIW My stock bottom has been blown (9.5lbs of boost and 458rwhp on a Mustang dyno) for over 5 years and nearly 27k miles without a single issue. I do take it to the track about 4 times a year so she is not 100% babied, but away from the track it is strictly short burst on on ramps and occasion boost on the street. I am also in the process of changing out my motor to an aluminator. Not because the stock motor took a dump, but peace of mind and dreams of higher hp goals. G/L [/QUOTE]
