usually the first really cold day of the winter, i'll goose it and the car will kick me in the @$$. I forget how much this car loves the cold weather.
Also, since i've got the flywheel lightened, 1st gear is a blast. A short blast, but a blast. Under full acceleration the tires are usually spinning towards the end, followed by spinnage in second, and depending on whether or not i'm lucky and whether i want to beat on the car a bark in third.
