Fair enough. You don't really need a dyno if you can measure speed over time.
Find a deserted road or go to the dragstrip and compare the average of your best 3-5 runs with that of a stock Z. Ideally, you'd be the one driving both...
Or, do this just for yourself before and after each mod. Whether or not you feel faster, if you are faster then you've picked up some power (well, assuming all other factors are about equal).
