Perhaps a cog belt to drive it, no slip and far less tension. Set the A-4's max output RPM at around 22~2400 RPM for the alt' output rating. I think that at that RPM transferring 13+Hp via the front should not be a big deal. And at lower RPM's the alt won't load the drive. I've seen huge "blower loads" on the end of many cranks with "cog drives". Belts and drive pulleys are also readily available.

Also check to see that the RPM's you drive at are within the thermal ratings IE so the alt won't overheat.
