Intercooler Ice required

[<wmtsmith@landracing.com>]

Will anyone give me their experience and/or a method to figure how
much ice I will need for my intercooler BEER tank.  Also experience of
using dry ice as a (supplemental cooling source if I don't have enough
room for the BEER cooler that uses bag ice alone.--thanks in
advance--please don't be hesitant--as Mayf says--Inquiring mind needs
to know
