[Three Peaks]

You're young enough that you probably grew up with 4 bangers in foreign cars that needed a turbo to get the power needed to feel like you have a fast car. My advice would be to get a ride in a Cobra with a plain old American V8 in it and see if you really think you need the extra power.
Besides not needing excessive power to make one of these cars ridiculously fast, the short wheelbase makes bad things happen in a blink, especially if you've never driven a car like a cobra before.

My advice would be to build/buy a standard V8 car first, then decide if you really need the extra push of the turbo or supercharger. I'm betting it will be quite awhile since you can easily get 450-500 hp out of a stroked 351W and it will have much better street manners.
