Porsche Turbo RSR Type 934
Porsche took auto history into a new era with the introduction of the 930 Tubro in 1974. The racing spec, road going supercar, made turbocharge technology available to Porsche customers for the first time, rapidly selling well over the planned production run. Porsche developed a racing incarnation of the 930 Tubro, called the Turbo RSR or Porsche 934, for the 1976 FIA Group 4 GT season.
Only 42 models were built during the 2 year production run from 1976-77, with the Turbo RSR dominating at GT races across Europe and America, including two first in class wins at Le Mans. Spotting a forced induction engine similar to the 930, the RSR was extensively upgraded yo improve performance.
The cooling system layout, including fan and cooling fins, was redesigned to achieve higher efficiency, while an oil cooler and intercooler were added to lower the intake air temperature. Greated power and torque than the original 930 Turbo engine mean that the Turbo RSR is capable of top speeds of around 300 km/h(190mph) and a 0-97km/h acceleration in 3.9 seconds. Like the 930, the Turbo RSR usesall wheel independent suspension with torsion bars, but with changes including alterations to the shape and position of stabilizers, and coil springs added for reinforcement.
The Turbo RSR brakes feature aluminium calipers and 917 style inner vented and pierced discs. The distinctive styling include enlarged overfenders to fit the wide tires, large rear spoiler and front air intake with oil cooler in the center and intercoolers on each side.
