CJ Motorsports VHR Intake Manifold

That is sort of a matter of perspective. An intake manifold design is a compromise. Adjusting the design will shift around its peformance range. If there was any free horsepower on the table, I can assure you Nissan would have found it before I could.

Since I don't stand a chance at beating Nissan at their own game, the only hopes for gains we have depend on setting different design parameters. It is possible that emissions or packaging forced a compromise on them, but other than that... It's safe to assume that they aimed for the greatest performance possible.

A manifold targetting slightly more torque such as the HR manifold does would create perceived performance gains by increasing power through the midrange, although midrange power doesn't exactly make for a faster car in terms of a drag race, but can make it more flexible and faster around a course.

I tend to be more critical of power "gains" though. I don't care for cooled-down glory pulls, or picking the best out of 12 runs to overlay from the worst of the before. I can't stand that part of this industry, and I am not a fan of people being tricked out of tons of money for a car that is only just barely faster as measured under a microscope. The butt dyno lies to please our pride.

When the time comes I will give you guys the data as it is. I don't think there is an intake manifold that will reasonably fit the engine bay and make great power for the all-motor bolt-on and tune cars. But maybe I just expect too much to personally label "gains".
