in first.. its down to the elbow on a cosworth which is the limiting factor.
So .. in first .. on a cosworth you would need to get a custom manifold which bins the elbow...
then .. you go for a bigger throttlebody...
on a cosworth .. 65 mm from a RS500 .. (standard is 56mm)..
this is enough to go to 600 ish...
i use one from an alfa V8 (76mm)...
hope this helps..
