Does anybody know how many HP you can get with standard S4 heads?

Any updates to this question/answer? For example if going for bigger turbos like straight RS6 or something similar? Still won´t get 520ish?

Sounds very good. So I assume this was done with std cams also? What kind of intake mods is required for that kind on power? The reason for asking is if I´d go for example GT2560r turbos would those be an overkill for the stock intake or could ~550hp be achievable with stock heads and cams assuming the exhaust system (and everything else) was done properly?

I´d like to retain the low end torque as much as possible so wouldn´t want to do the heads/cams.
