Re: Indy pop-off valves

[Glen Powell <gpowell@acacianet.com>]

*Perhaps* the pop-off valve might be good insurance for those that
experiment with the (risky) fool pump relay-defeat hack. Can a properly
functioning turbo actually be damaged by overspeeding due to no load on the
compressor -- like if the IC or a turbo compressor output hose blows while
WFO -- boost gets vented to the atmosphere and hence no overboost condition
or automatic fool-pump shutdown? What would be the failure mode of an
'overspeeded' turbo? Impeller explosion? Or would the max speed be
self-limiting? Lotsah people 'blowedup' ICs and hoses, but you don't hear
about exploded turbos.....? (yet  :)
