It does really depend on your combo and what you're trying to do. If you've got a slightly smaller then optimal carb, and you're looking for a little more mid - top end, then a tapered spacer might be worth some HP. Or, if you're turning lots of RPM with an intake that's a bit undersized. I've seen 15 to 20hp on the dyno plenty of times.

I went from a 1" open to a 1" Phenolic tapered spacer from Jomar on my 524. I never dynoed it, didn't have to my whole family noticed the difference. Difference in part throttle acceleration is phenomenal.
