[DML] Blow-off vs pop-off

[raddad@xxxx]

Both Wm Wilson and Bruce Benson are correct. But, they are talking about
two different things.

The blow-off valve is, as Bruce says, a boost limiter. It has been used
for years on race cars.

The pop-off valve is a relatively new item in the turbo world. It is, as
Wilson says, used to reduce the excess pressure that buils up between
shifts because of the throttle being closed. It is now offered as an
aftermarket piece by several performance equipment manufacturers. I know
of no one who has installed one (or two) on a DeLorean, but can think of no
reason why they couldn't be so installed.
