Charlie Springs??

[Swann, Benjamin R. (BSWANN)]

Good to know, but I plan to disable the hot-wired fuel pump, and correctly
install Q-chip.  It's a no brainer, just need the time.

Regards,

Ben

They are rated at 1.7 Bar(conservatively) and can be easily shimmed for
more.  I have one installed in 1 of 2 '87 5000CS Turbo Quattro Wagons.  This
has the fuel pump wired on with Ignition (not recommended) as that is the
way the car came.  This car easily aquires 1.8 Bar.  the car pulls quite
well, but I note some surging and flat spots in acceleration and
driveability, nothing major, but I've become spoiled by the setup I have in
my other wagon which uses QLCC chip, 2 Bar Spring, and some other combined
mods.

Use of the QLCC chip with this spring is a bit more controlled, as the
timing maps are appropriate for the amount of boost as provided by the
spring and assisted.

[Are "Charlie" springs still round & about or available from anyone?
Does anyone have a description of the physical dimensions &/or the estimated
installed boost threshold the Charlie spring provided over the stock?

 Ben,

If you see any old '80-'83 5000 turbos in the wrecking yard, there's a
pressure switch attached to the plumbing that opens at 1.8 bar.  Gives you a
bit more safety than a hot wired fuel pump.
