Supercharger Performance and Engine Performance Parts

he heart of the upgrade package is a Lysholm twin screw compressor elevating intake pressures to a modest 6 psi. This fairly low boost pressure means that the engine’s static compression ration can be left untouched and that the supercharger package can be a true ‘bolt on’ affair. Following through with this ‘bolt on’ strategy, MTM have coupled the supercharger with an integrated top mount intake manifold with integrated air to water intercooler courtesy of Laminova intercoolers. Also in the mix is an MTM bolt-on cat-back exhaust system exiting in an exotic dual dual (that’s four outlets) 3″ tips.

The car is further enhanced with suspension modifications, lowering, lightweight body parts rounding off the performance package. The result of all of this work is shifting power up from 420 hp @ 7800 rpms to 540 hp @ 8220 rpms. Torque is amplified from an original 317 ft lb , 430 Nm @ 6000 rpm to a new 412 ft lbs, 560 Nm @ 3700 rpms.

The attention to sound engineering design in this kit (using a twin screw supercharger, coupled with an integrated manifold and integrated intercooler) resulting in short intake path lengths, means that the whole package is both still highly throttle responsive as well as having more power delivery on the top end. Not only is it impressive that the car gains over 120 hp with this modification, but more impressive is that the power band growns from 1800 rpms on the stock high-revving V8 to a very meaty 4500 rpms between peak torque and peak power. This not only makes the car faster in a straight line, but makes it much more versatile on exiting corners and carrying its hefty weight and the weight of the AWD Quattro system in the lower rev range.
