With the forged internals, low compression pistons, etc... VF engineering should be looking a huge power gains but also huge $$$$!
They are going to boost the stock internals first. Just like they did with the E46 M3, which was capable of over 600 wheel on 11.5:1 with less displacement. Should be under 15k again, they are using a Vortech T-trim.
