I've emailed him about the issue of boosting a high compression ratio engine, to see if he's had any issues or knows of other turbo Z owners with issues.
It's not so much the compression ratio I'm concerned with - it's the integrity of the pistons and rods. The AMG Kompressor engines typically use a higher compression than the standard Merc engine and are still able to run high boost. The AMG internals, however, are strengthened to accomodate the boost.
It looks like Kleeman installs their superchargers (bolt on 400hp) without any internal modifications. I could be wrong on that, but based on the vague description on their site, it looks like the $22,000 kit is just for the blower, after cooler, assorted intake bits, and labor. They make no mention of internal engine upgrades.
Yeah, x'ed, someone was watching that auction carefully and was purposely outbidding every potential bidder in an effort to raise the final price. I have no proof of this, but that's what it looked like to me. There are currently two more auctions for AMG blowers listed now and I've emailed one seller offering to purchase his out right. We'll see what happens.
