Since Bob Martin wanted Air to Air intercoolers and the intercoolers are mounted in the engine bay area things are getting a bit tight. The intake air filter has to go into the spare tire area and will be ducted to grab air from the right side scoop of his Dallara replica. The details have been worked out on the test body using a free flow air filter that is from a 2.5 Subaru. Attached are a few pictures of the build, the top of the air cleaner will be latter ducted to the right side of the car when I have the road car to build the parts required. TonyK.
