Hey, are the runner pipes for the intake manifold the same diameter as the throttel body (65.5mm) on the GT-S?

 

[Shizuma]

sorry "throttle"

Not even close. Not sure of the actual diameter, but they have to be around half as large.

Hmm, i wonder if anyone is going to release a race intake manifold. Is there room left for gains, or is it already a good design stock? I know Hondas tend to respond very well to an intake manifold, such as the Skunk2 Pro series.

The intake manifold is actually very well designed, it has alot of things built into it that most aftermarket companies build into the designs of intake manifolds for other applications

The only other things I can really think of are extrude honing it to smooth out the interior and maybe adding velocity stacks to the entrance of the runners, but that would probably be a PITA.

It already has velocity stacks cast in - I cut one open to look

The sneaky b^stards :gap: ...the only reason I'm asking this guys and not measuring it myself is b/c my car's about three hours away...thanks for the replies though

Sick. How was the casting roughness inside of the plenum?
