2012 Dodge Grand Caravan Grill Block

I have not seen a lot of people modifying vans in the group (understandibly) so I wanted to post some of my own test data for others to have access to.

I have a 2012 Dodge Grand Carvan with the 3.6l Pentastar V6. It has 93k miles on it. I just replaced the spark plugs / air filter / engine oil. I took it on a 240 mile trip last weekend and averaged 26.44 mpg per my scanguage 3. The engine temperature hovered around 170 degrees F with outdoor temps in the mid 50's. With this information, it appears I am safe to experiement with grill blocks. For some quick/cheap trials, I purchased some clear vinyl to experiment with. I am going on a simlilar trip this coming weekend, and will update with my results. Pic below for reference.

Thank you. I've been lurking off and on since around 2009. I figured it was about time I made a post.

My wife thinks I am crazy, so we will see what the consensus is.

If you think your wife thinks you're crazy, isn't that a consensus right there?

With me it will depend on how long the boat tail is.

Remember Dark Aero?

Update:

With the full upper block, and 60 degree ambient temperature, it ran 180 degrees on the highway. In town in stop and go it got up to 204 degrees. I climbed a very tall mountain and it hit 214 at the peak.

All was good, however the 3 mil vinyl was not strong enough and got shredded by stones on the highway.
