If you're brave, go for it!

Properly tuned, and maintained, I have yet to have a EFI'd engine backfire..
It would activate til needed meaning not before several PSI of boost.  If
you have a backfire under boost, this is the least of your problems.

Lots of fuel, way retarded timing. Creats after burning, ie fuel burning
post combustion chamber.  Enough heat to drive the turbo, withoout the
engine actually being under load to do it.

Ol 1227148 controlled one..

To turn liquid to gas takes energy, the energy removed from the air drops
its temp.

 Or does it displace air?

The purpose is just like that of the intercooler, dropping temp..  In theory
the measured boost should drop slightly.

 Or does it just reduce the in cylinder cooling that it would have done?
I've been thinking too much too:)

The cooler the intake charge the cooler the intial chamber temp is., and the
less likely to detonate.
