Manhart has released an upgrade package for the current-generation 911 Turbo with its TR 750. Based on the 911 Turbo S, Manhart gets 99 extra horsepower out of the twin-turbo 3.8-liter flat-six for a total of 740 thanks to an ECU remap. Manhart didn’t release performance figures, but expect a significant decrease over the stock 911 Turbo S’ 2.7-second 0-60 time and 205 MPH top speed. Manhart also adds H&R springs that lower the car 1.2 inches and a Kline exhaust with 200-cell downpipes. The TR 750 wears Manhart’s trademark black-and-gold livery with no additions to the stock bodywork. The TR 750 package is available for order now.
