Default how much power can the coyote 5.0 make safely?

I have a 2011 5.0 with a vortech, boss 302 manifold, Doug Thorley Headers long tube tri-y's , o/r x-pipe. before the boss manifold it made 544 rwhp with a very conservative tune from vortech. Now the car is at racers edge tuning getting a full custom tune done. What would you guys say is a safe power on these motors?

Probably 550-600. There was a guy I read about with a whipple pushing well over 600 and it blew up on him.

There are never any guarantees but then you probably already know that.

To the OP. I would say you are getting close on stock internals.

There's no doubt it's gonna pull like crazy especially in the upper rpms because of the boss intake and these motors love rpms.

"I" would be a little nervous climbing close to that 575+ mark. Again, no doubt the motor will make some numbers but for how long? Just my .02

thanks for the input guys.. Im not one to beat on my car a lot. Its my weekend car. so i wouldnt be driving it everyday. But i do agree about for how long will the stock internals last. I think sometime next year im going to start looking into forging my internals just to make it safe.
the car was a 544 rwhp before the intake. so we'll see what the intake and a good tune do. what are you guys seeing the boss manifold make on cars?

oh as far as my coil covers, I got them painted out here where I live. the company that painted my car for me did the coil covers too. they matched the stripes I had painted. www.lge-paint.com L&G Enterprises in San Dimas, Ca. They do great work.

Mine are blue, I want them in Race Red along with a Race Red JLT intake, I think it would look sweet. I found them on AM though.

OP I like your setup, I even thought about it myself but I really want a 500 hp car without an SC, I think I can get there with an intake/tune and some headers.

Doug Thorley Headers did my long tubes and full exhaust. They are great. They built them using my car. they are a tri-y header. I made 36 rwhp with them.

Recently in the Speed channel featured "Two Guys Garage", they mod the 2012 GT with Roush charger, Boss intake, and many suspension mods. They incresed the hp to 540. I would say that's safe guideline to use.

Flash, the roush charger would not use the boss intake as it is a positive displacement blower and has a manifold below the blower that houses the a-w intercooler.

There are modders, even professional ones, who have put the stock fake forged conrods and stock pistons through over 600 HP at the wheels. But of course, on the stock conrods and pistons, you can be sure the engine longevity is been greatly decimated.

Personally, I say 500 BHP crank is as far as I would push my own engine with stock internals.
If I go for 500 HP at the wheels, I would prefer to have one of these:

Mahle true forged pistons, true forged H-beam conrods, etc.

It would also depend on how you drive it.
