However, they wont hold the power for a long time like a Terminator!
I really don't see how you guys think this is something groundbreaking... They "design" a whipple for the 2015 which has essentially the same motor as the 11-14 and you guys seem to be amazed by this? am I missing something here?
The story is a bit misleading. Volumetric efficiency in this case means it takes air in and moves it all back out. Congratulations, it's a blower, it should do that.
Less than 1hp at cruise? Duh. You're not making boost and the bypass is open. Of course it's a low power consumption figure in those conditions. Start making boost and the hp required starts going up.
Someone asked if centrifugal blowers were better with regard to not heating incoming charge: yes, they are a lot better. But with a single speed drive, they require higher engine rpm to start making boost, so low-end torque is reduced. Where a positive displacement blower scores is low-end power production.
I have tried for years, just messing around because I'm not an engineer, to make a multi-speed transmission to drive a centrifugal blower. But I keep coming up with big, clunky designs that won't fit under the hood. Almost all of the great piston engine fighters of WWII had centrifugal blowers with multi-speed drives. I keep trying to copy what they did, with no luck.
