1st track day in the bag with the new 914, no decent pics yet (there was a photog in attendants, but haven’t seen his pics yet). Car rand great and although running with much newer machinery she was holding her own once her driver brushed off the cobwebs... (IMG:style_emoticons/default/driving.gif)
Since this was essentially her first shakedown I found a number of little things I need to address, one in particular I’m questioning: After a few laps I noticed - mainly on a flat sweeper turn, when entering hard on brakes and trailing off while turning in I’d get a soft groan from my outside wheel (drivers in this case). I’m thinking wheel bearing? I’ve never had one go bad on the front spindle before, so I’ve never heard or felt the slight vibration before. Never really occurred on any other turns.... thoughts?  |

I agree may have something fundamentally wrong. Check your spark plug wires and fire order. I had an old chevy v8 along time ago that had two close wires swapped with similar issues to what you are describing. Would make sense why your afr is so low, actual unburnt fuel in the exhaust. My 3.2 with DC40 cams takes off like a banshee and yours should be faster, for comparison I am about 12.5:1 AFR at WOT on the high end.
