The build took Jeff four years, which isn't long by many of the FFR builds we've seen, but Jeff had a good excuse for his delays. Early on in the build, he became a father when he and his wife welcomed their new daughter, Jenna. He's had more than 60 brave passengers in the Roadster in the eight months he's had the car completed and on the road, and even taken home a few car show trophies. Admittedly, the first thing we thought when we saw Jeff's FFR is the same thing many comment on. How do you put that kind of power down in such a small, light car?

"I can put down 95 percent of the power with very little wheelspin," Jeff states. Since a turbo depends on load to make boost, and with the tall gears Jeff uses, the Roadster makes more boost with each gear change. With a Competition Engineering rear antiroll bar pinning the rear tires down, the Roadster puts down roughly 550 hp in First and about 600 hp in Second. Third gear on up, the boost is controlled by a boost controller, so Jeff can easily set it for the conditions he has to keep the car controllable. It certainly helps that the replica has the engine behind the front wheel centerline and a lot of its weight in the rear, including battery and water/meth supply tank, helping traction.

Jeff says the project wouldn't have been finished without the help of his father, as well as his brother, Jay, lending their technical expertise to the build. Help also came in the form of babysitting duty from his mother, Nancy, and his in-laws, Virginia and Jay Godwin, so he could get some time in with the project. Of course, big thanks goes out to his kids, Jenna and Luke, and his wife, Abbie, as they certainly had to endure those moments of absentee dad/husband that all "car families" have to deal with from time to time. It's usually a team effort that us gearheads get out to the garage and finish that project so the whole family can enjoy it!
