Hey Bill;
I hear you, and I asked Camden some of these same
questions, awaiting a reply. Their unit mounts directly to the block, and
appears well engineered, but as I said earlier, endurance, and what happens if
it blows, is my main concern. Been around the 1/4 mile tracks for more
years than I care to remember, and have seen a little excitement when the old
Gimmy 4-71's and 6-71's decided to cash in, not pretty. Conversely,
watching a turbo melt or lose a turbine blade doesn't get me real excited
either.........trying to find the best middle of the road.

Supercharging
Greg,
Superchargers are sometimes simpler to implement, but there are other
reasons they aren't as popular on aircraft. First they are a power robbing
device. There is a net gain in power of course, but the charger can require
10-15 HP to drive it at WOT and it makes the engine less efficient. The other
problem is you must be sure the unit is up to continous use in the
boost RPM range. Lastly the mount must be solid enough to hold up to
continous use as well.

As I have cruised around, looking at options, I came
across www.camdensuperchargers.com, who make kits for
rotaries. Has anybody had any experience with this? I like the
idea of less heat, and plumbing, but how about endurance? I know John
Slade had a lot of fun until he got the right Turbo, I wonder if the situation
would be any different with this.
