reading through some of this, a few things throw flags,

OP spins his motor up to 7800... the stock GT motors werent designed to spin that fast, yes it can be done, but the BOSS was designed to spin that fast... I personally try never to spin my motor past 7500. The boss has lighter valves, crank, different main bearings, different alternator, different cam tensions, etc to achieve this RPM safely.

One of the guys that OP is talking about posted and said Lund told him he was on borrowed time, which means, ENGINE IS MAKING TOO MUCH POWER TO STAY SAFE. To me that means that he is warning you that its going to blow, if you keep those power levels, start saving to build your engine, or back it off.

As others have stated, just because it broke when you werent pushing it all they way, doesnt mean when you were pushing it didnt do damage. The damage has lowered the "safe" levels of the motor. Its like once you blow out your knee, it will never be able to hold what it used to, and if it does, its just a matter of time before it blows out again, usually with less abuse.

Also, your comparing and saying that 75% of the Lund tunes you know of failed.... thats is NO WAY a fair comparision. That'd be like saying 75% of people have blue eyes, because of the 4 people you know 3 of them have blue eyes....

So in the end if you look at it, this whole thread is crap, and unless this was a troll thread, which would of been a success, the OP is basically an Idiot.

It's easier than picking your rods up out of the street. :)
while we're on the subject I'd love to know the current valve spring pressure on the overheated/overreved springs. Me I wouldn't raise the max rpm on my engine by 14.57% without springs that can handle the harmonics of 8000 rpm operation minimal.

I think you need to leave your engineering career behind the computer.
Not even the best in these industries throw numbers and percentages around like you do. Not everything is a mathematical equation.

If you can't debate me with facts in an adult manner than that's too bad. Your personal attacks only illuminate your lack of knowledge and lack of ability to discuss things in a mature and educated manner.

A valve spring change isn't quite "simple" to do on these motors...

It really is that "simple" if you can't or won't prepare your engine for an extended rpm range, than you "simply" shouldn't rev it that high. My only regret here is that it wasn't your engine!!

Please refer to post number 55 on page 3 where I clearly say at the end that my car shifts at 7300 and not the 7800 rev limiter and you say my car does.

so its the tuners fault when you guys have stock motors and are going to throw a 200 shot with e85 ( your sig ) and complain about blown motors. 14lbs of boost? I understand it didn't blow up with the 200 shot but those were your intentions. I know the 5.0 is the next best thing since sliced bread according to you guys, but really? If I owned one I would never run any of the combos listed in the first post. I hope you guys get everything fixed and good luck. It does suck when a motor pops. Its never good to hear. especially to another fellow mustang owner.

Wow, forged internals, then power adder. That doesn't seem that hard of a concept to me. If you go forced induction on stock internal, is not a mater of if it will fail, but when will it fail.

Any chance there is catalogs of a WOT highway dragstrip pull. That would answer most questions right there.

Ford racing does offer a 2.9 supercharger with 624hp with warranty. So I feel like some where down the line ford engineers thought a little over 600hp is safe. Mine put down 550whp with drivetrain percentage loss I should be around 632hp at the engine almost the same as what ford warranties.

Pretty sure they do not. The warranty is only available with the 525hp, not the 624hp.

You said you hit rev limiter and that rev limiter is 7800:

"Yes it hit the limiter but found that not to be the problem due to progressive controller having a cut off. I went back through and checked my cut of for nitrous and it was 7400 and rev is at 7800 so no nitrous in the system as I first thought when it hit rev limiter."
