i know the edelbrock ones are good but the d-series intake manifolds have long *** runners. looking for something with a big plenum and short runners for my 400+whp d16. only thing i could find is a obx manifold.

 

why doesnt anyone make a good boosted d16 intake manifold?

 

Because you don't usually see that much of a gain till very high in the powerband. Most B-series manifolds don't show much gains till 7k+, and a turbo honda making power only between 7-10k isn't all that common. WHen you compair the honda manifold to many other 4-cyl motors, it has fairly short runners.

If nothing else, contact full-race for a good answer.

 

STR makes a great manifold for a Z6.. Not sure if still in production but I got one on my z6 and Im pushing 418whp!! Here's a site that has them for sale??
