Any thought to ducting air directly to the filter from the outside rather than the round louvers in the rear screen? I have seen side NACA ducts on either side piped to the top of the engine where an oil cooler sat. This arrangement could work for engine intake air.
This weekend I was able to make a little progress, I got the intercooler and piping roughed in and finally received my modified engine harness, flex fuel kit and the VEMs standalone which has been preloaded with two tunes (E85 and gas) for my turbos, engine, etc. The harness is now totally plug and play, no wiring required! Definitely the easy button. I have to show off these injectors too, probably the most expensive part of the build but designed for both tunes and tested for both tunes. Its the little things like this that have really added up.
