Hi Mark, this was at a VMax event (Maximum Velocity), 2 mile runway and basically go flat out. My car was running medium mods, B&B style headers, Fabspeed duel out, 1.0bar spring in standard wastegate (getting around 0.9bar), K27HFS turbo, IA fuel head, IA airbox, Ported heads, Ported manifold, 964 cams, tapered injector blocks, 964t intercooler, the weak spot was a dodgy WUR, I had an adjustable WUR in hand on the day but blew the engine on the first run.
From my experience trying to run optimum 12.5 to 12.6afr is plain silly without doing major verification on each cylinder. Keep it around 12 to be safe.
I have a modified 993tt motor in the 930 now, just waiting on the second oil cooler to be fitted and some tuning and i'll be back out there going flat out

Mark, I see you have a KX250, I raced motorcross from schoolboy through to my early 20's, it's a while ago now but my last season was on a KX250, only club racing but those bikes are in my blood! Porsches and motorcross, we have a lot in common
