Yes and those weight loss numbers look even better when you realize that 20hp improves straight line acceleration only. Weight loss improves acceleration, braking distance and cornering speed. Back-of-the-napkin 986 performance improvements look something like this on a typical 2 minute race track:

Add 20hp, cost: $3000, shave 2/10s of a second/lap
Remove 200#, cost: zero, shave 2 seconds/lap.
Upgrade suspension and run R-Comp tires, cost: $5000, shave 5 seconds/lap

Some mods deliver a lot more measurable bang for the $$ so spend your long winter tinkering wisely.
