Similar but more eggagerated than a lightweight flywheel...ability to rev faster, and higher, without damaging engine internals, with matching bearings and counterweights. OF course, if the price didnt give you a hint, this is pretty much a race-only application.
Unless your referring tot he 89-91 lightweight rotors, as compared to earlier versions, which are both lighter and higher compression. This raised the engine's redline 1krpm and the hp(along with other slight revisions in intake and mapping) 14

Yeah, IMO. They give you a 8krpm redline, higher compression, and a bit more power, but they take away a bit of torque down low, and are known not to hold quite as good an idle as the 86-8 heavier versions. This doest mean your new engine wont idle right, just that htey have a tendency to be harder to get right than the others.
Driving an 86-8 car then driving an 89-91 car makes the latter feel like it has a lightweight flywheel on it...standing starts take just a hair more slip to get going, and the torque below 2500rpm isnt quite there.

I wonder if anyone has ever thought of having new rotors machined from titanium? I wonder if there is anyone out there with enough $$$$$$$ to try it sometime? I wonder how many mortgages I would have to take out on my house to be able to afford that much precious metal?
The idea just kinda popped into my head while thinking about how the Acura NSX connecting rods (what the hell is a connecting rod? this is a rotary forum) are made of Ti and can be revved beyond belief without failure or damage. Can you imagine the weight reduction? I just don't know all the specifics on the properties of Ti but I know it's light and strong (not to mention VERRRRRRYYYYY expensive! If anyone hits for like 100mil on the powerball, let's try it. Just an idea!

Ti has some very nasty properties when trying to introducing it inside an engine.  Ti galls very easily, so it needs steel inserts or very good bearing inserts.  Ti also expands at a different rate than Al and Fe, so you need to be very careful about clearances.  In the end, why not go aluminum rotors with steel inserts?  It's a lot cheaper, and just as light...
