Smooth-Filtered: K&N Ford Mustang RTR

Dave Martis competes in the AI class with his K&N Engineering Ford Mustang RTR and has allowed us to show you the details of his amazing ride.

I haven’t known Dave for very long; in fact, the day I pulled into K&N Engineering to shoot the car and get the details of the build was the first time I met him face to face. We met when I asked CorteX about his car as it was being built. At the time, I was drooling over the details that I could only just see. I asked if I could do something on the car itself, mostly expecting to get pictures from CorteX and some marketing material when I asked about Dave’s car on Facebook. Instead, they introduced me to him.

The car itself started as a body-in-white, where the manufacturer sends you a chassis that has no engine, drivetrain, suspension or windows — basically the most perfect way to build a brand-new race car. It was then turned into the car you see here today. CorteX is a suspension manufacturer that creates some rather trick stuff for the S197 chassis. This is CorteX Racing’s Torque Arm and Watts Link setup. The torque arm eliminates the need for the upper 3rd link that Ford uses and improves straight-line and off-corner bite while also improving the roll steer of the live rear axle.

Bassani worked with Dave and his crew at K&N to create this exhaust system for the RTR Mustang. It features long-tube headers and an x-pipe that help get the fumes out of the engine with minimal back pressure.

The axle is a modified version of the Ford 8.8″ rear end, but has been beefed up with a Drexler LSD. The ring and pinion ratio is 4.10:1 made by Ford Racing. The axle tubes were replaced with stronger, larger ones installed by Currie Enterprises.

Fuel is held in the Fuel Safe Racing Fuel Cell and the trunk spare tire well was cut and removed for it.

An Aeromotive A1000 fuel pump takes the 91 Octane gas from the cell to a K&N fuel filter.

Thanks to these components and to the rules set by American Iron, you can expect this car to make between 450 to 500 horsepower.
