The only side effect is that when the engine is cold the s/c will be louder for about 1-2 minutes. Everything else is the same. The crank pulley is only enlarged on the plane that spins the s/c and altenator and both will spin 17% faster. The altenator can easily spin faster without any harm and nobody has had an alternator failure due to a pulley on the 2.3L Kompressor in 5-6 years that these kits have been available. No other pully company or tuner currently offers a kit that does it differently for the U.S. market.
I know Carlsson in Europe offers a 3 pulley solution but nobody has installed it yet on any forum and they won't sell directly in the U.S. Also Kleemann in Europe offers a 2 pulley solution (1 pulley is not really a pulley but a ring you screw onto your factory pulley) but it requires a special order belt from Kleemann. The really large MB tuners in the U.S. like Renntech and Brabus use a single pulley design like ASP but charge slightly more.
