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?

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.
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.
