I ran the SXX with an X12 10.5 using 2 dot timing. When using this speedie the gearing needs to be run much shorter. I finished up on 9.4:1 using feel on 5 and boost on 7. The motor was coming off the track at around 85 degrees but this is about right for an X12 motor (they usually run hotter than other makes). It was a little quicker than the guys using the X12 with the Tekin I think.

I thought I should post this becuase earlier in the night when the gearing was set shorter I was having issues with Lunging... The long gearing cased the car to become a little Jerky. I would suggest you all try shortening your gear ratio's.
