http://12v.org/urs/4.2 V8 vs 3.2 F6 tuned.jpg



Stuck my 2001 Boxster S with an Audi D2 A8 4.2 AUX engine on my dynojet today. New V8 puts the previous flat 6 to shame!! Nearly 90 more lb/ft of torque at 3500 rpm. Still revs out to 7200 like the 6 did, but with more urgency. Still has the same charm of the rev happy boxster.

The 4.2 is not internally modified and is breathing through an OEM boxster S muffler.

The old 3.2 S flat 6 had my tune, headers, no cats, open mufflers and an afe cold air intake.

Both on 93 with similar ambient temps.

Seeing the new action in this thread is getting me motivated to get back to work on my AUX swap. It has been sitting waiting for me to mate the harnesses together for months while I focused on my '04 SE flood car project. Now I want to hear that V8 roar with life.
