I spoke with AA and they don't expect to have their kit ready until early next year and don't expect there kit to be either below $10 grand (could of course be wrong) or to produce much over 500bhp.
With the forged internals, low compression pistons, etc... VF engineering should be looking a huge power gains but also huge $$$$!
