Interesting (well I think so) log from Oulton mishap.

Motec data log from Oulton last Saturday. Where the cursor line is you can see the throttle is at 100% but the boost takes a sudden dive. This is usually not good news at all, maybe a turbo failure. In this case it was an intercooler pipe becoming partly detached. After my heart stopping throttle lift off I tentatively glance at the instruments and risk a bit of throttle again, but seeing little boost on the gauge head back to the pits. I just love data logs now, and feel lost without a decent engine log to check after a run. You can see the Lambda go daft after the I/C pipe comes adrift, too. You can also see the engine efficiency take a dive, in fact you could pretty much diagnose this failure by e-mail.
