A new intake plenum and runners have been on the "to do" list for a while now.
While doing some reading the specs. on the Cayman, I noticed "variable length intake system." Of course this got me thinking....." 914 retrofit!!!!". Anyone ever tried this? |

I suspect adapting onto a different engine will be a WAG as to whether runner length and ID are optimized for the engine. And if not installing on a 911 engine, what do you do with the extra runners?
And then, the method of controlling the VarioRam hardware.  |

There will probably be some improvement, but to really optimize the system you need either dyno time and a way to change components around, or FEA of the intake stream at different RPM.

But by the time you do all that, you could build a bigger motor or just buy something bigger. |
