Dude, love this build. Great job! That S&B CAI looks awesome. Very rarely do I advocate for a "CAI", because it doesn't normally do anything. But you can tell that the particular design on this, where it replaces EVERYTHING from the nose to the turbo, will actually probably HELP (and I stress the word 'help') increase airflow ... in particular if you get tuned (like I plan on doing by Cobb as soon as they release the 2023 tune version). It's definitely something down the road that I'm thinking about.Having now completed several multi hour interstate road trips with the roof rack and Pelican Cases I can provide the following fuel efficiency details from my experiences.
In Florida most of our interstates have a 70mph speed limit, so all of this data is from spontaneous trips to Mexico, it's also using 93 Octane gas in all of these trips.
4 hours @ 71 MPH averaged 27.9mpg
4 hours @ 75 MPH averaged 24 mpg
2 hours (2 separate trips) at 85ish MPH averaged 20.2mpg
Before adding the cases I was seeing closer to 28mpgs at 75, so there has definitely been a loss with the cases (each case also has gear in them) but it's nice to have the full trunk available for trips.
With regards to wind noise, before the cases there was no noticable increase in wind noise from the JCR Roof Rack over the stock Badlands, with the cases there is definitely more "wind against a wall" sound but no whistling I've heard from other racks and roof toppers. With the radio on its not noticable at all.
With that being said, cantilevering the solar panel off one of the cases has created some... Interesting driving mechanics during high single directional wind events when driving next to large semi trucks. Car moves around a lot like my focus use to when driving next to semis. Just wanted to put that out there Incase someone tries to do something similar
That gas mileage is excellent for that roof rack. On a recent trip from Miami up to Cedar Key, I only averaged about 23 miles a gallon with 4 people in the car, fully loaded rear end, sloggin cooler tow, yakima rack, with a fully extended yakima basket, in where I probably exceeded the roof threshold and was at maybe 160. I usually had it right at 70, and rarely pushed it to 75 or higher. I could tell that the wind drag was serious.
However, I also think the fact that I recently increased my tire Diameter by a half inch without telling the PCM, might be throwing it off a bit
