High power to weight cars are ideal for mechanical carbs up until the point that you have so much torque that you can't pick up the throttle with out blowing the tires off the car.
The vacuum carb theory is commonly used in dirt Late Model racing (2300#/800+HP). Max torque and throttle response is needed when there's traction. But, as the track dries out the amount that the secondaries can open is restricted and delayed or the carb is switched to a vac secondary model. The vac carb works very well in keeping the tires hooked up off the corners, without limiting HP on the straights.
If your car "suffers" from way too much torque and throttle response for the available traction, it will make it easier to drive off corners IMHO.
