I received my new Volant Intake and Moes Performance 87mm Ported Throttle Body this past Friday and had a chance to do some good testing this weekend. Both mods came from Moes Performance. http://moesperformance.com/
I started by installing only the throttle body first. I drove around town about 20 miles and I can honestly say I felt a difference. I might not have the best tuned butt dyno, but throttle response is a little better and it feels like it pulls just a little harder, especially up top. Then I installed the intake. Power wise this also made the engine feel a little stronger. What I really like about the intake is the sound. It makes the Hemi growl like it's supposed to. It's not an annoying growl and can really only be heard over half throttle.
As far as gas mileage, I have picked up about 1 mph on the highway. I had to make a 120 mile round trip on Thursday and Friday-Saturday so I decided to try and set up an MPG test. On Thursday the Jeep had the stock intake and throttle body. I reset the MPG display, set the cruise right at 75 MPH for the trip and finished with 18.1 MPG, which is right about where it always is. Our highways around here are like roller coasters so with that and driving 75, MPG isn't always the greatest. Then on Friday with the new mods installed I departed and tried to drive the same way and at the same speed. Once I got on the highway the cruise was set on 75. MPG was reset before I left my house and I finished the first half of the trip at 19.3 MPG. I did a little in town driving on Saturday and headed back home that evening, finishing at 19 MPG. This isn't the most scientific test, but I've got over 6k miles on the Jeep and have never had gas mileage in the 19's, or even high 18's for that matter. I'm sure if I were to slow it down to 65 I could get into the 20's, but I just can't drive that slow. 60 in this Jeep feels like about 45.
Overall, I am very pleased with both mods and I think both work great together. I would recommend both of these mods to anyone wanting a little more power and MPG! Now here's the pics!
