| 944 Turbo S 016 AOR cryotreat with 8:31 ring and pinion
Hello:
I write this post only to tell you my experience with my 944 Turbo 016 AOR gearbox crygenic treatment in my first endurance race (4 hours) of this year (last weekend). I followed your advice and send my ring and pinion to cryo treat (to metal wear in Illinois, although I live in Spain)and shot penning last month Feb 2008. The only problem I had was two small pieces broken in one tooth in the ring and another in the shaft of the 3rd gear (I donīt know if it is normal in the shot penning). My reason to do this treatment was that I wanted to swap my R and P stock 8:27 with a 944 S2 R and P 8:31 ratio to get less maximun speed for the track. The result was very good at least at the moment. I have now 250 Km\h in 5 th gear at 6700 rpm and it looks like that this 8:31 ring and pinion works fine and hold the torque and the power (45 Kgm and 315 CV during 4 hours).
Thank you very much again to Pete, Jim, Ryan, Jack, Ron and other guys that had the kindly in answer my questions |
