But now that I think more into it, it's not a forged bottom end, so you're right, it's not designed for that much power. Still, I'm not particularly impressed. Lets see someone forge the bottom end and crank up some boost. 557 out of a 6.0 is nothing. For the cost of the turbo build they might as well do the engine as well and get some real numbers.

You mean high horsepower world. We got Coastal Dyno down here and they do a lot of custom turbo setups on Cobras. I've seen some sick #s but they are on the high maintenance side. They usually run a lower boost on the street. With the guys I hang out with, if they don't have a 600 rwhp Cobra then don't even come out to play . . .
