The cabin/ interior side of the cover plate, dig the Karmann coachwork badge>> found it at the L A. Lit show ยก
The alternator bump-out is not too invasive into the cabin.  |

Marty,
The kit came with a little 70 amp alternator. That won't work for me. I have to have amperage to run the electric AC compressor. I need about 250 to 300 amp alternator output. I am not running a distributor on mine, so the alternator is going to be mounted way lower in the space where the distributor was mounted. If I have to, I can put in a dimple in the firewall to accommodate the alternator pulley. I am also going to run it with one v-rib belt rather than the second belt from the fan drive pulley, with an idler above the Clewett dynamic tensioner. That will make the belt run in a T path and keep t low to clear the firewall. This is the alternator I plan on using... https://www.mechman.com/400-amp-fits-6-12-c...m-fitment-only/ 400 amp, and a computer controlled regulator. It is a small case, so it should mount low in the distributor space. |

Clay, make sure that the Clewett pulleys, belts, and their ratios are close to your horizontal fan specifications ; keep the air flow rates close/ or same as the Porsche design.
