On the old setup like you had I trapped the same, 124, but only pulled a 12.45 because I spun all the way down pretty much (street tires & cold weather lol). It's strong now, but I've had nothing but problems with it up until this point. Lightened it up & maxed out the stock blower. I don't do digs because of 2 reasons, first I got KW Variant V3 coilovers, which are meant more for road racing than drag racing so my weight transfer would suck on a hard launch, & I'm scared of breaking my transmission or rear-end with my luck. I doubt you'll ever get any track times for me, if I do go I'd be more worried about my trap speed than my ET. I'm more worried with looks than power now though.
124 is moving for 12.45!
I hear what your saying.
Anything can break, anytime. You mod the crap out of something, it breaks, you fix it. Simple as that. Would I be mad if I had the #8 issue? Sure would, but I made my car produce 202 rwhp more than stock, so I really couldn't cry to Ford about it, could I?
In the same way, while your car still features a stock blower ( no one could tell it's ported), would you bring it to the dealer if you blew up something in your driveline while attempting to launch a 4000+ car with 650 rwtq and sticky tires? I know I wouldn't because I took the chance when I modded it.
I could care less about all the hoopla surrounding this Ford TSB concerning mods. It's nothing new, nor is it unreasonable. If you sold your car to someone, and they put twins on it and it made twice the HP than how you delivered it to them, then they break the motor, would you cover the cost of a new motor? Didn't think so. Lol.
