DeMan Motorsport specializes in engine rebuilds – from race builds to factory restorations.
We also build race engines from scratch and can make performance modifications to your existing engine. We can blueprint your engine, dyno test it and certify your horsepower and torque. From Engine Builds and custom ECU programming to Turnkey Racecar Development and Construction, DeMan Motorsport can handle all of your needs. Engine dynamometer testing is performed on custom engines and by customer request. Assembly, engine layout design, and build clearance checking are all done on site.
Porsche transmissions, like their engines, are precision equipment, requiring extensive knowledge and expertise to repair and rebuild.
DeMan Motorsport has the expertise to totally rebuild your tranny or make the necessary repairs. We have the factory tools to set the ring and pinion and handle any transmission job, large or small, be it a 901 or a late-model cable-shifter. Factory and custom transmissions are rebuilt and bench tested. Performance analysis of the racecar is simulated to select gear ratios that provide the highest level of on track performance.
