Project 987.2 Cayman S: Getting More Out of the Engine to Chase the GT4 Part 3

The stock airbox was removed from the fender area and we installed the cone filter and block off plate.  Now ram cold air from the cars side scoop feeds the engine directly.  We got one of the silicone elbows and cut a segment and clamped it to the cone filter adaptor.

We attached the other silicone elbow to the GT3 throttle body. Then we cut an aluminum tube to the right length so we could could connect the elbows together.

Now we have a 3.25 big diameter passage from the air filter to the plenum for great flow!

The PVC line routings are somewhat different between stock and IPD.   One of the lines was blocked off with the supplied plug.

Our intake tract mods are now complete. In our next segment we will work on our cars oiling system for the engine and transmission to assure that the bearings get a good supply of oil even with increased lateral G’s and to help keep things cool even under hard track driving.
