Heat is a killer in air-cooled motors, whether you're using 930 heads or Carrera heads. As long as you keep your boost levels to within moderate levels and have proper A/F's, EGT's, oil and inter-cooling, there's no reason why it shouldn't live on a race track.

Personally, I wouldn't go running sustained boost levels of 1.3bar on a race track, but 0.8 - 1.0bar would be fine I'd think.

My Carrera is purely street and has been turbocharged for many years. No issues with cracked/overheating heads whatsoever.
