[Land-speed] Oct meet

Here is a more likely alternate theory..
You lifted the head gasket sent compression from the now dead hole into
the cooling system and blew the cap off..You would be amazed at how much
water an engine can ingest and not get hurt... Also  how easy it can be
to lift a head gasket as well..

As near as I can tell Sparky, the rad cap backed off to the point where
once it built up pressure it released it all at once and the air filter
for the supercharger is right in line with it.I think the engine
ingested a large amount of fluid all at once.When I took the filter off
there was a puddle of fluid in the intake pipe leading to the
supercharger.I do not know yet but maybe the engine experienced a
hydraulic lock in two of the cylinders and broke pistons or bent rods
but one cylinder had no compression at all, so I did not bother to test
the other-I knew I was done. At first I thought I had left the cap
undone but upon inspection I realized the cap was not clamping onto the
rad tightly enough and vibration may very well have backed it off enough
to cause the disaster we experienced .But we live and learn and next
time before each run Jim and I are going to do a thorough inspection of
the little things to try and avoid a repeat of this. We will be back
asap. Scott
