| For those of you who think this design is "impossible", don't blame Jim.....it's just an almost "impossible" task. Why do you think I'm working on my 5th design now? The problem with exhaust manifolds isn't a technology
vaccuum....there's just no room under the hood. The problem w/ designing a manifold for cylinder #6 is that
the steering shaft location leaves few options, and is
compounded by the VG layout with driver's side head staggered rearward. Besides all that, there are motor mounts, oil cooler ports (P/S), wastegate actuators, tight cowl and frame rail clearances, and the whole issue of assymetrical turbine housings.....not to mention problematic cylinder head stud locations. A week ago, we just had a lengthy discussion on the "log" style manifold flowing "one cylinder at a time". Personally, I think that the log manifold at some point will reach a limit....maybe not just on a dyno, but in response or engine reliablitiy. Although his design in its present form will not "fit" the VG engine or the Z32 chassis, I admire Jim's effort. His focus on a "tubular" design may be another indication that the traditional log-style manifold may have seen its better days. While I'm working on my latest "AAE cast turbo header" I hope he can use all his high tech software to finally design a new intake manifold.
