All the cast manifolds for the VQ have been a big restriction when it comes to big numbers, and no, 700whp is not big numbers. I am talking numbers north of that. Not to mention using an external wastegate, and something other than a T25 turbine housing with a tubular manifold.
You will never see a big power VQ with a cast manifold, but you will see one with a tubular, equal lenght manifold.

I don't mean to argue that tubular isn't better than cast "log" manifold. I am talking about the bigger picture, which is making the entire kit work in the space we have without giving things up like accessories. For our platform, I just don't believe top mount is a better solution and I think the product offerings out there tend to support that circumstantially. I'm not saying I don't want someone to try, or that it wouldn't look cool, or that it couldn't make great gobs of power, but rather, that it's not the best engineering decision for our cars accounting for all variables.
