So you are getting you a set of these made? Would "Road Car" Be Daily Driver? What Manifold would you be using just a custom one, how long would be your runners to upport the 8,500RPM and how would your low end power suffer? I know it wont matter because it's for rally and staying higher rpms but I'm curious.
