The fact that the Rotrex drive spins much faster is not the cause of the more desirable boost curve. That curve is directly related to the fact that the blower speed is not held at a constant ratio relative to engine speed.
The planitary gearing and traction drive don't separate the compressor from the rpms of the motor -- they just allow a smoother and faster ramp up to full boost speed ---

From what I read at the BRP forum their blower is almost ready for release. Lately they do an update every few days - the last one is from Friday and says that they were doing tuning on the car over the weekend.
Here is the thread with the last few updates:

I can bet you'll see the BRP kit on the market much before Jackson, Fastforward or the Axial guy - the Fastforward and the Axial guy are just in the talk phase and haven't even touched or experimented with a S2000 ...

I think the hype of the rotrex had us all misled a little. It looks like a standard centrifugal boost curve, the only advantage seems to be lower noise from the drive and impeller.
This is worth a quick read:

I think what we were all hoping for is something that spooled fast and then effectively vented the excess rotation speed of the motor using some kind of clever oil that allowed the drive to slip. I hope to be corrected but I have found nothing to suggest that is the case.
Had me all excited for a couple of days...

Look at the increase in the torque before Vtec on the Civic R!!! Flattens out the Vtec crossover, while also giving substantial gains across the powerband!!!
Most of the other superchargers don't do anything before Vtec...
By the way, the expensive oil refered to on the Elise forum is probably a fluorocarbon based oil...kind of like liquid Teflon...very expensive, yes, but very temperature and chemically stable. Essentially, you don't ever have to change it out!!

We're all in the black for info here, but I think that forcing conjecture to resemble truth goes a bit far. And, calling a yet-to-be-proven design "hype" and "misl[eeding] does no one any good, either.
I'm no expert on FI systems, but I do tend to be able to tell facts from opinion by the source and "proof."

I'd be interested in you explaining how this has anything to do with an F20C engine? Yes, the Civic and S2000 are both made by Honda, and use VTEC technology. But how the two engines/cars respond to FI is not necessarily the same.
The dyno of that 6.0 liter motor with the Rotrex in my opinion has no merit on this thread.
I have a CTSC and it makes zip/zero/squat/nada power below 5-6K.Its all in VTEC...
By seeing the civic dyno there is a large difference between this and a comptech/Vortech and it is definitely a good difference.

No need to hide behind the computer. Im sure you could squash me by the looks of your avitar. which brings me to a question. How on earth do you fit in the s2000.
My shoulder just barley touches the door
