FFR Customer Jeff Barfield’s Mk4 in Modified Mustangs & Fords Mag

Huge congrats and kudos to Factory Five customer Jeff Barfield as his turbocharged 600 HP Mk4 Roadster is profiled in Modified Mustangs & Fords Magazine by tech editor Mark Houlahan.

Jeff base his build on a 408 cu. in. Windsor block and used Borg Warner’s T6 83 mm turbo for boost.  The article has a comprehensive list of the engine parts and other upgrades.  Steve says that “with race gas and adjustable boost, the engine is capable of over 1,000 HP, but after the first ride, I got out of the car shaking and found my limit.”

The article is written by Modified Mustangs & Fords technical editor Mark Houlahan.  Mark is a great editor, active on Ford, Mustang, and Factory Five internet forums, AND Mark has built his own Factory Five Mk3 Roadster, so he knows a think or two about build quality.

You can find the article in this month’s September 2012 issue of Modified Mustangs & Fords Magazine.  Congratulations again to Jeff and big thanks to Mark Houlahan!

Mark has also written a series of articles about his own Factory Five build.  You can read them on Modified Mustangs & Fords website by clicking here.

Factory Five is Closed Today, Monday January 26, 2026.

I made the call to scrub FFR operations for the day. The drive in wasn’t bad, and most roads are clear. Unfortunately our plow crew was late, and the day dawned with 3-4′ drifts in the back parking lot! We will be at work and at full strength tomorrow. Sorry for any difficulties this may cause.

Three Generations Embark on a Type 65 Coupe Dream Build

Dave Ryan’s Type 65 Coupe build is moving right along—and it’s become something even bigger along the way. In collaboration with Factory Five Racing, V6 Media is producing a short film documenting the build process. Recently, Dave’s father, Vaun Ryan, sat down to share his lifelong passion for performance cars and motorcycles—sparked as a young boy on the family farm in Utah, building a homemade go-kart powered by a hay-elevator motor. That curiosity for how things work turned into a lifetime of mechanical enthusiasm, passed down through generations and now culminating in Dave’s Type 65 Coupe build, which is a…
