This means instead of a impeller RPM plot that has a constant state of rise, you actually get a speed plot that is a bit "fatter" in the lower speed range and performs better than traditional helical/straight gear direct drive. This is also why the rotrex has oil reservoirs, I believe the nature of the friction drive generates heat.
This is how I understand it, I could be completely wrong... its very interesting operation  |
Sounds a whole lot like the clever wording I referred to in another thread on the subject of Rotrex units. That "fatter midrange", that the Rotrex customers-to-be always reference when discussing their reasoning, amounts to what? 3 ft lbs?
If the Vortech kit was limited to the same amount of airflow that the Rotrex kits are, I suspect that the boost curves and midrange power would be identical. It damn near is now.
