That 20% is all loss, 20% lower economy compared with a turbo in otherwise equal circumstances.Superchargers do, however, cost a little of the power they produce. Unlike a turbocharger, which runs off the engine's exhaust (waste) and therefore doesn't drink up any additional power, a supercharger is driven by a belt or a chain connected to the engine -- and that does drain some power, just as all other belt-driven accessories do (like air conditioning, for example). This is one of the reasons a supercharger can't deliver a promised and consistent power output -- the supercharger itself affects the way a car runs. In some cases, it can sap up to 20 percent of the engine's power before it contributes its own boost to the equation. For people who really want the specific experience of a supercharged engine, though, it's worth the tradeoff.
Not for Naught but superchargers generally feel like all motor and they are more reliable, while turbos make more power, they run cooler, etc. I have a rotrex supercharger on my k20. It makes power all the same. The fitment is probably the issue but I'm sure it could be made to work.It's a lot more difficult to fabricate a bracket with perfect alignment for the belt than it is to make a manifold adapter and downpipe. Or that's my opinion anyways.
Superchargers also are inherently less efficient and would zap a small, but probably significant amount of power off boost.
Just my opinion, but anyways I think it would be pretty neat to have a supercharged Insight. I however will likely always choose turbo over supercharger.
Didn't the F1 cars employ that to make power? Expensive option but rotrex is VERY efficient, basically like a turbo on the pushing end powered by belt. Don't be put off by the parasitic drive. They are very reliable and make power reliably which comes on right away.An electric supercharger would be ideal. No pulley and could be mounted most anywhere under the hood. 120V motor would be small and light (think handheld hair dryer) and run off the IMA battery.
I wonder if an AC clutch could be utilized on a supercharger ?
A very few superchargers have these. Most Mercedes OEM superchargers do, I believe. They also have a bypass for the air to go around the vanes, which otherwise wouldn't let any air past.I wonder if an AC clutch could be utilized on a supercharger ?
