So I've built up this little 3.6L 993 with 108 super sport cams, 50 gallon flow injectors, TPC supercharger & liquid intercooler, and a Haltec elite ECU. It only fell 20 hp short of the target. As I prepare to put the GT3 gearing in to the stock transmission C2 gearing I had this nasty premonition of snapping axels... #Awful...

I researched the subject and It appears that there may be three part numbers - but possibly only two axels (standard and turbo)?? I'm hoping to get input from those in the forum with experience on the correct axel. Does anyone happen to know if the turbo part number is machined for higher torque? Are three versions of 993 axels? Any input on the subject of 993 axels would be greatly appreciated...

Your input may save a lot of money and heart ache later so seriously - many thanks in advance! For those who want to know hp and torque I have the image below with the stock gearing on the dyno.

Thanks again,

axle part numbers are 996 now so what you'd want is a 996 turbo axle.
cruise the 996 gt2/gt3 forum for blue axle vs black axle to see what people are using and where to buy.

opps, forgot the link, here's some cup car axle info with part numbers and description, even a link to high end demon speed 1/2 shafts.
