Bottom line is, with the intercooler pipes, you wont gain nothing.

Intercooler is another thing. you should get before and after air temp sensors on the intercooler pipes and measure the stock one then the aftermarket one. thats the best way IMO

Podi makes a nice differential gauge to measure two temps at once and automatically tell you the difference between both values.

Why not just go 3"?

Found this link today before I found this thread. What no ones mention is at the stock power levels and stock sizes ic pipes air flow is around 170mph. Could that speed be more clue to Porsches intentions then anything else? Would intercooler cool better with a slower air flow then a faster one, making the intercooler more effective. Smaller pipe at stock power levels would increase the speed with it spool, however would that results in less off a temp drop across the ic?

If so, then by increasing the ic pipe size inrealtion too power levels inorder to maintain this air flow speed would result in cooler air ?

I'm going with 2.5" myself as its that or 2" which will mostly likely be to small
