dunno about the 414 specifically, but unless your belt is skipping you should be getting the power you need to accellerate adequately. infact, it's usually a tight belt that bogs a car down. excessively loose belts can be problematic due to vibrations or resonances, but i dunno how easy that is to feel or see on the track. and really, many racers run the belts so loose that they are just short of skipping. especially in stock or on single belt cars. that's my 2 cents.
