First up, I own myself a 2013 3.7 Mustang and have always loved it. The power delivery is smooth, and more than not stability at top revs is oddly, perfect.
Ive driven all sorts, and had my hands in all kinds. So, I like having options.
After what seemed like a disparaging amount of time looking for proper upgrades and parts for our cars, I found a rather interesting website.
First, the website:
Super Six Motorsports - V6 products that make your life faster
They sell Ported heads, stroker kits, etc for the 3.7 and offer some options I have not seen in a lot of places.
Secondly the article:
This article gets into the nit and gritty of our engines as well as the ecoboost variants, and talks advantages, disadvantages, weak points, and strengths.
May be nothing, but It seemed worth sharing to a good community such as this.
