What size battery do u use for type 1. High comp motor

All those with street driving high comoression big cc type 1 motors. What battery do u use....

12 V you could find a type 3 auto starter that spins over slightly faster

I've run a Century 58EBMF with a Wosp Starter Motor on a type 1 1776cc engine at 9.9:1 compression with no issues.
Hope that helps.

Thanks for the replies...i check it out

You can get a 'Cranky kit' which adapts a subaru starter motor for use on a VW, I used to need two batteries to turn over the 1916 when I had it, but that kit spun it over way quicker with one smaller sized battery. Paul from steelart customs should be able to help you out.

Nothing special in battery in mine and 11:1 .. no issues
