Anyone who has built a fast stick car knows how hard it is to build a reliable, fast stick car. It’s a constant battle between having a clutch and transmission combination in the car that allows for more than one pass before needing a rebuild, or another clutch. When you start getting into four-digit horsepower, the list of clutches that can handle that power and torque is really, really short.

Fathouse Fabrications is one shop working to figure out what works, and what doesn’t when it comes to applying that kind of power to a stick car. Ben Stoner, Fathouse’s VP owns the car, and he tells us the car was all built in-house.

The engine in Ben’s GT features Wiseco pistons and K1 Technology rods, but the heads, cams, and compression ratio remain stock. The power adder of choice is a Forced Inductions billet 76mm single turbo, and all the work took place at Fathouse Fabrications in Martinsville, Indiana.

“We did a custom single turbo kit, along with a pretty basic engine build,” Ben says. The engine retains its stock compression and stroke, but Fathouse added Wiseco pistons and K1 Technology rods. The heads and cams also remain stock. Everything else on the car, though, is anything but stock. The combination far surpasses the capabilities of the stock fuel system so Fathouse added a custom return-style system using twin Walbro 465lph fuel pumps, ID1300 injectors, and E85 in the tank. “We tune it in-house with HP Tuners and the car makes right at 1,200 horsepower to the tires,” Ben adds.

The rest of the drivetrain is likewise modified with an RPM Transmissions-built Level 5 T56 Magnum with a Mantic triple disc clutch, and a suspension made up of BMR springs, and upper and lower control arms; and Viking shocks in the rear with Strange Engineering struts in the front. Strange was also sourced for a pair of 35-spline axles and spool. The GT sports a full interior minus some of the rear seat, and still has power heated seats, full stereo, and the like.

Fathouse’s goal is to run in the 8s with the car in 2017. Once they get the clutch figured out, that goal will be conquered.
