What up Crews? I ran for Axe a couple of years ago. I still have running an old Mamba, two Cobra X1, and a 25 Cobra X1. The 25 is a BEEEAST, with much better mileage than a 28.
As for pipes, my team engines came with the #3010 (3-chamber) pipe, which never made it to the mainstream market, in lieu of the 2050. However, I preferred the JP3 on the 21's for shorter tracks. The JP4 is still on my Cobra 25, which replaced my RB C6 w/2045, so you know it had to be for real.
As for plugs, I caught hell with everything, until I changed fuels. After trying all the Axe plugs, and the OS-P3, I settled with the Odonnell 97T eventually.
You may want to help bring back to life the Axe Rossi thread on SGrid. When you come down the NC, please bring an extra conrod for me.
Good luck this year,
RJ
