Manifold / TB rule revisions

[Chip42]

I'm with Eric, and have been on record thinking the same (and more) for well over a year.

in a displacement to weight class with street car origins, using street car parts is a very good way to separate the haves from the have-nots. FI will overcome a lot of those issues and, especially with the more modern turbos, sacrifice a touch of peak hp for huge gains in area under the curve over a NA sibling, even with small restrictors. couple that with a huge industry-wide shift (more true in smaller STL type engines but still) toward low end torque and efficiency over performance, and you get a similar enhancement to the NA cars but a lot less peak power potential in most cars than in a few exceptions. yes, hp/L numbers have been on the rise, but once the rules are factored in a lot of that dies off in lost "gains" and you're often times left with a relatively shitty (for racing) intake and head designed to get 11ty MPG on 7-11's 87 octane. NA generally can't compete with FI under that basic premise. open the rules and let the displacement be the driving force like it's supposed to be (at least more so), and fields will be a lot more diverse, and yes, maybe more expensive. and the gap to FI should shrink.
