If you have a ’97 to ’04 GTP or GS, your car will run about 14.8 in the quarter mile in stock form. There are lots of variables here, but this is a realistic average based on our experiences. If you have an SSEi, your car will be about one full second slower. The Bonneville’s are only a few hundred pounds heavier, but they are slower for several other reasons too:
- additional weight (several hundred pounds)
- poor weight distribution for drag racing (things like the battery in the back seat, aluminum hood, aluminum control arms and aluminum front bumper all work to reduce the percentage of weight on the front tires, resulting in less traction during acceleration)
- larger front brakes (more rotating mass reduces power put to the ground)
- larger tires and wheels (increased rotating mass takes more power to accelerate)
- restrictive PCM (much more aggressive traction control system cannot be overridden by simply pulling a fuse; PCM will actually retard ignition timing if you try to power-brake the car)
- no Performance Shift function (so shift points are lower and shifts are slower)
- no air opening behind the headlight means that removing the headlight won’t give you any cold air
The Regal GS is slightly (a couple tenths) slower than a similarly equipped GTP, for some of the same reasons as the SSEi.
