Pulled my Mazda Torsen Diff. and the alum. housing was cracked. What's amazing is we were able to set the fastest time (over 85 Miata's) @ Hallet Raceway 1.8 mile circuit on 100 treadwear tires 1:28.2 with our 184 whp N/A ITB Piston motor beating the old time of a Supercharged 260 whp time of 1:28.3. Driver only had 1 session and put down the time with the cracked housing which does affect acceleration and possibly handling. I have a pretty good idea what the piston motor can do and can only imagine what the 13B will do.
Note: Last week testing the 1st gen RX712A Semi-PP in the 1/8th and the R&P Gear broke. We will try again this week.
Semi-PP is not new to us.
