Thinking Supercharger Until This Video
According to this guy, a turbo is a better choice because you get more hp under the curve. If I go to 7000rpm and reach my peak of 400hp then shift and go down to 5500 rpm and loose all my boost which puts me at 325hp where the turbo will be at 375hp, the same exact car with a turbo shifting at the exact same time is going to pull on me if I'm the one with the supercharged vehicle. Obviously these numbers are made up and this is just an example of what I think I learned from this video. Is this true? Does it make that much of a difference in low boost 8-10psi situations?
Also, why not have a supercharger that would normally produce 15psi at 7000rpm and 10psi at 5500rpm if 10psi is all you want you can install a wastegate that releases anything over 10psi and that way you get maximum boost through the rpm range when youre going through gears. Is this thinking flawed?

This video is slanted to sell turbo set ups. His 'pro and cons' list made me laugh.
You match the power adder to your motor and driving style.
You can match either with proper sizing and putting the power in the 'sweet' spot for your RPM range. A good low end turbo will not have top end, a good top end turbo will have poor low end. Same with an SC (generally speaking - but you need to break down into PD blowers and centri blowers).
His comment about SC's not getting to peak power right away is wrong. My V6 had full tq a touch over 2500 RPM and the tq was a FLAT LINE all the way to redline. My 4.6L is pretty close to the same. PD blowers LOVE to make crazy power down low in the RPM range, which makes them great for street cars and road course cars.

you can do this, people do it BUT now you are spinning the crap out of it heating the air way up.

I have a Supercharger on my 4.6L with zero problems! The main thing I like is that it drives like a stock Mustang until I put y foot into it! Then hold on! For resale my setup looks more like a Shelby and easier to sell! Love it! I'm selling it, just so I can build a other one!

No, my Mustang is a 4.6L and the 625 hp ad is for the 5.0L Coyote. Roush webstite does not show the 4.6L Supercharger now, but I'm sure it is still available.
