For the settled in Austria and Switzerland company O.CT Oberscheider Tuning GmbH, car compressor engineering for cars made by Audi, Chevrolet, Chrysler, Dodge or Jeep, is part of the daily job for many years. The success is resounding, as can simply be checked by reading different publications in the specialized press.

As only the notion Supercharger Conversion comes into, not only insiders get keen-eared! In the present case, O.CT Tuning has „converted“ a Dodge Challenger SRT8 with 6.4 liters of engine size. During the conversion, there have been installed a compressor kit and a charge air cooler system, but before all, there was made an individual software optimization. By doing this, the software gets professionally matched to the particular car – so, not at all „off the peg“. The work is done on the company own high tech test bench. And the result has not any reason to fear the competition: 476 serial HP increases to 564 HP and the original max. torque of 637 Nm was boosted up to impressing 735 Nm (here is concerned the version with MOT / DTC certificate, further steps with over 600 HP for racing sports are possible).


Another no less noticeable example for compressor engineering made by O.CT Tuning, is presented by a Jeep Grand Cherokee. Here also, 468 serial HP increases to 564 tuned PS while the max. torque jumping from 624 serial up to 735 tuned Nm (version with MOT / DTC certificate). The pulling power, when driving the above mentioned tuned bolides, gets sensible in the beginning by moderate pressing in into the seat, with increasing rpm to be compared with the start of a jet airplane. In the same time, the compressor forced breathing emits a genial sound. Optionally, there is additionally available an individually adapted by O.CT Tuning stainless steel exhaust system beginning from the cat.

By the way, the compressor refitting with the above mentioned power enhancements, O.CT Tuning offers also for Dodge Charger and Chrysler 300C, both motorized by a SRT8-6.4 engine. Furthermore, O.CN offers also a compressor refitting for the new Dodge RAM 5.7 HEMI! Another important fact – the indicated values are confirmed by MOT certificate, thus being absolutely within the law. Indeed, O.CT Tuning can present a MOT / DTC certificate for these supercharger conversions. The (optional) exhaust system can be registered together with the compressor conversion.


It is not surprising that the mentioned measures for power increasing made by O.CT Tuning are not the „end of the road“. The parade example for this is a Dodge Challenger SRT8 refitting with project designation „OCTSRT8-700“, whereby the engine size on special customer’s wishes has been enlarged up to 7.0 liters and, consequently, has been equipped by a compressor. With 720 tuned HP and 875 Nm of max. torque the aimed 700 HP benchmark has been clearly cracked! Thus, O.CT Tuning show in an impressing way what is possible „for daily use“.
