I have a 2005 Hayabusa engine in my kit car. I have a SBD motorsports dry sump oiling system. Total system capacity is estimated at 7 quarts (sump, tank, lines, and oil cooler). I took off the PAIR valve and the associated plumbing. Westfield included a header and muffler with the motor, so it's really not that modified to start with.
Question is what oil is recommended for the 'Busa motor for lapping day activities and some street duty?
The message forums and locals have me at 2 final options:
1) Amsoil 10w-40 Bike Synthetic
2) Mobil 1 Racing 4T 10w-40
