And when you say blower, are we still specifically talking about centrifugal superchargers?For power delivery, you can't beat a naturally aspirated engine, or an engine with a positive displacement blower. The torque curve on a naturally aspirated motor or roots-type blower equipped engine is broad and flat and the torque is there immediately and the engine/power is predictable.With centrifugal superchargers and turbos, the torque curve starts later in the rpm range... generally speaking. And said torque curve is usually sharper, with a peak or point. This makes for power that isn't there down low, but hits like a freight train up top.You can learn to use either to great effectiveness, it's just a matter of what you want or enjoy. I, personally, like the down low immediate power of a well built n/a motor. With positive displacement superchargers being a close 2nd. Turbos and centrifugal blowers are last on my list, especially for road racing. Texas mile car, yes, big single turbo or a big centri blower.I am a huge fan of consistency and predictability. When I press on the gas pedal, I want an immediate, linear, predictable response from the car. With naturally aspirated engines, and positive displacement superchargers, this is generally the sensation you can expect.With a turbo or centrifugal supercharger, you press in the gas and it's almost like nothing is happening, then BAM!, here's your power, all at once, you better be holding on. And that's cool. And you can learn how to use that and play to it, but I prefer the more linear power progression associated with n/a or roots motors.</blockquote>
