I always have and always will like the scoops, regardless of induction.
Latest reports suggest they actually are pretty close to making the same power. It's the RPM cap that's making the difference.
The new expenditures undoubtedly had an impact on participation, but make no mistake, the fields weren't exactly flourishing in the couple of years prior to the change. The class doesn't get the exposure the nitro classes do, nor will they ever, so it is a millionaire's playground. And as long as an engine leasing program runs nearly a million dollars a year, it will remain that way.
Overall, I still enjoy the class. It's not the class I grew up loving, but nothing is like it was 30 years ago. The bottom line is the EFI change, although about 15-20 years late, was necessary. The scoops are just aesthetics, and the wheelie bar change (which is the most baseless change of them all) has had no measurable impact.
