    Anit-Crank-Drop cap solution?

    Would'nt it be possible to fit a relatively large cap between the battery and the dc-dc psu to prevent powerloss while cranking?

    (If this has been asked before then please forgive my utterly useless and rude no-search-before-posting behaviour)

    A "proper" DC-DC should not have problems during cranking. If it does, there is either a problem with the electrical system in your car or the DC-DC unit.

    I've said it before, and I'll say it again: tank circuits do not fix the problem, they only mask the symptoms.

    Make sure you have a new, high quality battery (ie. Optima), that the grounds are all in good shape (maybe run an extra one to the engine block and frame) and that the battery terminals are clean and tight. Connect the DC-DC as directly to the battery as possible.
