Guys take it easier eh, no need to bash each other for things like this.
From personal experience I am running an entirely stock 7 bolt which initially had the stock 8.5:1 pistons but had to replace them with 10:1 N/A pistons (don't ask why long story). Take it with a grain of salt, but I wouldn't say there is a major difference in spool times or power. Then again, the car hasn't been tuned for the higher comp. pistons so that's also a factor. Runs at 12psi on stock T25.
We can all agree that, if we could get around knock effectively, more compression will be better. It's simple math; more overall efficiency. But to really decide if you want to go this route, it would really depend on your build and how you'll be using your car.
