Test drove a 5.0 Today

I think calling that safe might be a stretch. Sure it will probably last a while but I would think the stock bottom end would eventually fail. I like to think if Ford will warranty their 525whp kit that is safe, but since they don't warranty the 625whp kit my guess is 700+ wouldn't really be safe. At least in the eyes of Ford.

Have you ordered your kit yet? I go back and forth on wanting one but I think I've decided not to as long as this car is my daily driver. A couple guys that come to our local sports car shows are putting down some nice numbers with bolt ons. One has 420 whp with the Steeda CAI, tune, and Flowmaster cat-back. The other is putting down 430 with CAI/tune/catback plus the Boss manifold.

I have the Steeda CAI, Bama SCT tune, FRPP X pipe and FRPP Sport axle-back which should put me somewhere around 410-415 whp which feels pretty nice. I'm not really hurting for anymore power right now. I might throw the Boss manifold on later and call it a day power wise. Maybe I'd go FI later down the road when I pick up a real DD. Right now I want to do a few appearance mods and some suspension stuff. I am going to need to replace the stock Pirelli PZeros later this summer as well. Oh, I also want the Barton shifter and bracket.

How's yours going along?
