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.
I did not choose a dyno on a rotex charged honda over a non honda engine deliberately.
It is the only dyno I have found for a rotrex charged 4 cylinder engine.
Surely some information on what the charger does in other applications is more relevant than no information at all?

Looks like BRP will have some dyno numbers next week. That's awesome progress lately.
Hmm so BRP hotside with A to A intercooler, Jackson, FastForward coldside, Axial Flow. I know Fastforward is going for CARB cert and I suppose Jackson is too. How about the others?

With the recent discovery regarding the power curve of the Rotrex, my interest is rapidly slowing down. I will need to see an impressive dyno sheet to re-spark my interest.........However, #'s aren't everything.

Some of you still get it wrong.
The Rotrex CAN boost from as low as 1800rpm as per their info if you mash it from this rpms (same would go for a tiny turbo). It does not mean that if you just cruize along on partial throttle that you are boosting, since a blow/pop off valve will vent the boost.
And if you floor it, it will boost, but once you are in those situations, you go from 1800rpm to redline and than shift up (who races from 1800rpm anyway), what makes you drop to around 7000rpm. So it's not like you will be driving 1800-9000rpm on full boost all day long and wearing your engine out.

Very well explained-this is a concept that is really genius in design and hard to understand for a lot of folks.On my previous setups, my MPG was unchanged under normal driving situations and would only decrease with "racing", WOT pulls etc...

Very well explained-this is a concept that is really genius in design and hard to understand for a lot of folks. I believe on the old Jackson Racing kits-it was reffered to as an "air bypass valve".On my previous setups, my MPG was unchanged under normal driving situations and would only decrease with "racing", WOT pulls etc...

It's interesting that the new 800+ h.p. Koenigsegg CCX uses twin Rotrex superchargers. There must be something more than just the fact that they're Swedish for Koenigsegg to choose them for their supercar. Would two fit in an S?
