I understand. It's your car, but I just figured why not just get a couple more horses? Even if you put it to 400RWHP....that is a nice street car. My 96 Cobra doesn't have trouble with anything around town. **Now...I don't go down to organized street races or anything**, but on cruise nights, I don't have much trouble.
I agree about the supercharger whine too. It's an intimidating sound, but you just have to have enough boost to back it up. When I raced this HCI 6.0L GTO...I had a little trouble but came out by half a fender wellllll into 4th gear. If I had 10 or 12 lbs, he wouldn't even have come close.
