Beside the obvious difference in material, we struggled making 700 to the wheel on an HR engine. As the boost pressure increases, peculiar issues begin to arise. Making a cast manifold will only pave the way for this platform. We are also planning on testing the manifold on an NA application to see what kind of results we will get.

But what exactly are the differences between the VR38 manifold and the VQ37 manifold? Is it purely the material/design/legths of runners, or are there a series of reasons why this will be a much better improvement?
Just curious how this one say stacks up vs the stock manifold and say the Motordyne manifold as well?? |
