Message So how did we kill the car? Our track setup up was 17
PSI, with 18.5 deg BTDC, 100 octane and Aquamist
starting at 7 PSI. The car ran strong and cool in the
low 200's and with EGT's in the 800 deg C range. The
3.5 deg of advanced timing helped the low end response
and brought down the EGT's by 80 deg C. We were very
happy and did a lap at the very long and fast Willows
Springs at 19 PSI with only slightly higher coolant
temps, but the day was also getting hotter. Between
tracks, I just turned off the boost controller for
about 10 PSI max and never pushed the car at all.
Well, this is where we blew it. On the 6 mile road
between the hotel and T-hill, we were setting the high
boost setting on our boost controller to 18 PSI and
boosting to 18 PSI for verification. Well forgetting
that we didn't have racegas, we saw a big cloud of
smoke behind us. We didn't hear anything. We got to
the track and saw oil in the engine compartment coming
out of the dipstick. Thinking we may have just
overfilled the oil, we cleaned it up and went out on
the track for a warmup lap. Unfortunately, the car
was smoking badly, so we brought it into the pits
where Joe R., pulled the plugs and checked
compression. We lost the compression in cylinders 2
and 6. It looks like the rings went. The car was
well enough to drive home without problem.

Ouch, Very Ouch.
