Throttle Body Improvements: 986 e-gas

[Gary in BR]

I don't know enough about this to be considered an expert but I will give my thoughts.

We desorkel and see a HP increase.
The "cold air intakes" increase air flow and we see a hp increase.
The new plenums that are being sold for the Cayman and 996, 997 models change the airflow and sees a hp increase.

So logic seems to dictate a larger TB will bring more HP.

I think this is something worth looking into, I would like to see pre and post dynoes along with track times.

There is a pretty good book on this subject written by Jeff Harmon. He has done more engine hot rodding over the years than anyone I know. It is not the final word on this but it is well written, reasonably current, and does a good job of showing you how to make more power with any engine platform while dispelling the engine mod myths floating around on the internet these days. This is a useful reference for anyone interested in hot rodding or power mods. It gives you the knowledge to separate true performance improvements from marketing hype. Worth a look.
