I think that is safe. WOSP alternator is a robust unit and powerful for its size. It's the size that is the limiting factor and I don't believe there is a more powerful unit that will fit within the unique confines of a pre 964/993 fan assembly.

I am not familiar with the 964/993 alternators and I am don't know the specifications of their fans. Is it possible to retrofit the M64 engines shroud and fan to an earlier motor?

I have seen custom brackets and pully assemblies utilizing larger alternators on race prepped 911's but those have also been using a flat fan configuration.
