I have an '07 Shelby GT/SC. Whipple 550 supercharger. It's the twin screw kind. Has a liquid intercooler - this is important just as it is with turbos. All work done at Shelby. Went from 320 HP to 550 HP with 493 HP (dyno) at the wheels. To answer the question.....it drives like a normal car unless you put your foot into it JUST A LITTLE BIT! Then it goes like heck! You don't even want to give it much throttle until third gear. I think the centrifugal type have a bit of lag, which is why Shelby went with the twin screw type. Does it handle like a 911? No. But at 64 I am not capable of judging corners like I used to, so accelerating in a straight line is a thrill I can enjoy.
